Pcb dendrite12/31/2023 Metal dissolution: A strong alkaline condition attacks the anode and the power-leading contacts respectively – usually created by environmental pollutants or flux residue. Other substances, such as the flux, can also participate in the electrochemical migration process, which is divided into three (3) steps:ġ. The chemical reaction within a PCBA involves the copper in the board as well as the inorganic and organic compounds that constitute the substrate. Other key factors that can contribute to electrochemical migration are the PCB material composition (plating chemistry), uncleaned flux residue, active chemistry concentration and distribution, board surface roughness, and the environmental conditions to which the PCB gets exposed (e.g., Humidity, Temperature).įigure 1: Dendrite Growth due to electrochemical migration in PCBAs Īn overview of the electrochemical migration process inside a PCBA is presented in Figure 1. PCBA's reliability is highly affected by the chemistry of the soldering materials, and the activity and ionic nature of the residues. These dendrites are a common root cause of field failures, and they can be either intermediate or permanent. The outcome of this process is the formation of dendrites, which cause surface contamination, device sensitivity, and a rise in flux residues. It is the formation of conductive metal filaments across a printed circuit board (PCB) when dense current leakages occur, in the presence of an electrolytic solution. How Do Dendrites Grow on Electronic Assemblies?įlux residues on the circuit’s board surface can lead to a process called Electrochemical Migration. It is estimated that failures due to electrochemical migration have increased in recent years compared to what the industry experienced in the 70’s through 90’s. This might lead to short circuits, electrical failures, and compromised functionality, posing significant risks to the device's operation and potentially resulting in costly recalls or repairs. Moreover, one of the most concerning consequences of insufficient cleaning is the formation of dendrites, which are microscopic conductive filaments that can bridge closely spaced conductive traces on the PCB. Even in cases where “no-clean” solder pastes are used, the residues they leave behind can interfere with coating adhesion, and negatively impact the board’s performance. This compromised adhesion can result in coating delamination, reduced effectiveness in protecting against moisture, and increased vulnerability to corrosion. However, failure to adequately clean the PCBAs before coating can lead to a range of problems that undermine these protective benefits.Ĭontaminants such as flux residues, dust, and other particulates left behind during the assembly process can impair the adhesion of conformal coatings to the PCB surface. It enhances the circuit board's longevity and prevents product returns for manufacturers. Conformal coatings are thin polymeric films applied to PCBAs to safeguard them against environmental factors such as moisture, dust, chemicals, and corrosion. With this in mind, this article aims to showcase the importance of cleaning even “no-clean” fluxes in printed circuit board assemblies.Ĭleaning PCBAs before applying the conformal coating is a critical step that influences the reliability and performance of electronic devices. However, it has been demonstrated that even “no-clean” solder paste can lead to electrochemical migration and dendritic growth, which are one of the most common causes of failures in PCBAs. No-clean” fluxes can save expensive steps in electronic card manufacturing, they are safe, effective, and reliable when used properly. This type of flux is marketed to, and assumed to not leave significant amounts of active residue on the board’s surface after soldering, but multiple studies suggest that this is not necessarily the case. This “no-clean” solder paste intends to eliminate the need for cleaning the circuit boards after assembling all the metal parts into them. In the electronic industry, the manufacture of printed circuit-board assemblies (PCBAs) has been greatly simplified by the adoption of “no-clean” fluxes during the soldering process.

Cyberpower battery backup testing utility12/31/2023 Of course, there are some expensive uninterruptible power supplies that will do the trick but you don’t necessarily need to break the bank to keep your computer protected because the line-interactive CyberPower CP1500PFCLCD is able to offer the necessary protection. Some devices are known to not work well or to be completely incompatible with a simulated sine wave UPS (such as sensitive audio or medical units), but, recently, people have also experienced some problems with computer power supplies that require an active PFC power source compatibility. CyberPower CP1500PFCLCD ReviewĬyberPower Systems is a well-known USA-based manufacturer of uninterruptible power supplies, surge protectors and other backup power solutions, with some of its more popular products being the affordable line-interactive UPS devices. That’s why it’s important to verify the power consumption of your equipment prior of purchasing (it can be done by using any inexpensive electricity usage monitor, like the cheap Kill-A-Watt. Important note: Before purchasing any uninterruptible power supply (UPS), you need to make sure that it can handle your devices. CyberPower CP1500PFCLCD vs Eaton Electrical 5P750RC vs Tripp Lite SMART1500LCDT vs APC BX1500M – Performance That’s why UPS manufacturers pride themselves with lots of additional minutes or even hours (depending on the power consumption), so you don’t have to worry about power outages and have enough time to save all your work before performing a safe shut-down of your computer. Some people only use surge protectors as a way to protect their computers and other type of electric devices, but, unlike an UPS, you can’t prevent data loss in case of blackouts or brownouts (also, they are useless against low voltage, which can do some serious damage). If you’re unsure about what UPS should you purchase in order to have your devices safe and protected, I have compiled a list of the best uninterruptible power supplies (UPS) to help you make the best decision (mainly addressing the line-interactive UPS). Most electronic devices should work fine with an UPS that has a simulated sine wave output, but, the more sensitive equipment may not play nice with anything less than a clean, close-to-ideal sine wave UPS (a common scenario for some sensitive audio devices or medical equipment – Active PFC power supplies can work with a good line-interactive UPS). Based on the technology that’s used, we have offline UPS devices (also known as standby uninterruptible power supplies), line-interactive UPS devices (the more commonly used type of UPS in households and smaller offices, since these are more reasonably priced) and lastly, the online (double-conversion) uninterruptible power supplies which work very well with sensitive electronic equipment – usually found in the medical industry, laboratories. The uninterruptible power supplies come in various shapes and sizes, but the main differentiating factor remains the topology.

Best places to view illuminations epcot wdw12/31/2023 Advanced Dining Reservations are not required or offered.Many locations offer Mobile Order which allows you to skip the line.Sometimes referred to as “Counter Service”.Here is what you should know about each: Quick Service While dining at Disney World isn’t all that different than eating in the “real world,” there are few things to know about in order to make your experience easier.ĭisney groups their restaurants into two main categories: Quick Service (which is like fast food) and Table Service (which are places that are a little bit nicer, where the food is brought to you). MONSIEUR PAUL (DINNER) – TEMPORARILY CLOSED.RESTAURANT MARRAKESH (DINNER) – TEMPORARILY CLOSED.LES HALLES BOULANGERIE PATISSERIE (DINNER).RESTAURANT MARRAKESH (LUNCH) – TEMPORARILY CLOSED.LES HALLES BOULANGERIE PATISSERIE (LUNCH).AKERSHUS ROYAL BANQUET HALL (BREAKFAST).LES HALLES BOULANGERIE PATISSERIE (BREAKFAST) – TEMPORARILY UNAVAILABLE.Join the Disney Express Lane Facebook Group to discuss this and many other Disney related topics. Have you been to La Hacienda de San Angel during Epcot’s IllumiNations: Reflections of Earth fireworks? What did you think? Don’t forget to make your advance dining reservations way in advance, because the later times usually fill up with other guests who also want to view the fireworks from inside instead of outside with the masses. If you are looking for a way to get away from the crowds, have a bite to eat, and still get to see Illuminations, I highly recommend this reservation to any guests visiting Epcot that would like a front row inside view of this spectacular show. There are always new things to do each time we visit Epcot and there are so many excellent dinner choices in The World Showcase, but we stay true to this tradition for Illuminations because it was such a fantastic experience for our whole family. Even though my daughter is older now and is not afraid of fireworks anymore, we still have dinner during Illuminations at La Hacienda de San Angel every time we go. That experience at La Hacienda went much better than I expected and really was a highlight of our trip. My husband especially liked having his drink inside without all the crowds outside. My daughter was not scared of the noises and she and I were in awe of the show and the fireworks. The restaurant dimmed the lights, piped in the music, and we enjoyed a front row seat with a spectacular view. Our cocktails and even our food was delivered promptly and when it was time for the show, we were enjoying family time over our cocktails and our daughter was happily eating her dinner. Our table was located so that we were sitting by the window near the water and we had a very nice view and I was anxious to see how my daughter would respond. We were seated with plenty of time before the show, so we spent a little time perusing the menu, which consists of Mexican cuisine and a pretty nice list of cocktails including several margaritas. When we checked in at the reservations desk, we asked for a table that would give us a good view of the fireworks. We had made an advance dining reservation to La Hacienda for a little after 8:00, because Illuminations started at 9:00. La Hacienda de San Angel sits near the water of the World Showcase Lagoon next to where Illuminations takes place and she suggested an inside table that would be at the same time as Illuminations. The hope was that being inside would keep our daughter from getting scared of the loud noises, but allow us all to enjoy the beautiful display that is Illuminations. My travel planner at the time recommended getting a dinner reservation at La Hacienda de San Angel-a table service restaurant in the Mexico Pavilion. Epcot’s version of night time fireworks is knows as Illuminations: Reflections of Earth and many of my friends told me that it was not to be missed and could be very emotional.Īfter hearing those recommendations, I set out to find a way to see these fireworks without scaring my two year old. She had been frightened in the past by the “pow pows” as she called them, but we did not want to miss out on all the great night time shows. My husband and I knew she would love Walt Disney World, but we were not sure how she would handle the loud fireworks. The first time I went with my family to Epcot at Walt Disney World, I was an adult with a shy two year old. Find out which restaurant in The World Showcase is a favorite fireworks viewing location amongst many guests who also want to view Epcot’s IllumiNations: Reflections of Earth in our newest addition to our fireworks viewing location series, La Hacienda de San Angel: Disney World Fireworks Viewing Locations!

Houzz small home office12/31/2023 I'm torn regarding the distance between the space and the laundry area. I could leave it open to give that hall more space, and it would still have a bit of "art" to it, open or closed, compared to a regular door. That would give me room for a sliding door. Maybe the pantry could open into the office. I hadn't thought of using it for the office (because we were considering a pantry, which has a door). haha!īuckhead, it's funny that you mentioned the barn door because I've been wanting one since we started plan hunting. You're right, I'm constantly picturing myself "living" in the floorplan. Thanks for posting your layouts, everyone! That looks nice and spacious, gopintos. If you have children playing outside, you may need a view into their play area with quick access, etc so my best advice fwiw, is just picture yourself using your space. I can see my driveway (grand central station at times), I can see who comes and goes at the front or from the garage, or from the back porch, and who passes through on their way to the stairs either to go up or down. But in my mind, I have pictured myself using this space a 1000 times, so that is why I talk like it is done, and I feel much better about my office and getting done what I need to get done. I dont know if it will work like this or not yet, I can tell you in about 2 more months haha. Then when I need quiet time, I can close the doors. By simply moving my door, I have gone from from feeling isolated to being in the middle of the things that I need to tend to all day long. So it is office space, but when you walk into the kitchen and glance over, it looks more like a little breakfast nook.īut my point is I guess, think about how and when you will use the space. Or my husband can grab some coffee and bring his laptop to the table also. I like to work at the table, so I have a round table in the middle of the office space, and then I can turn around and wheel over to my desk. So I lost some cabinetry on that wall, but I extended the kitchen cabinets down both walls on the side into the office, one to be a desk area, the other side surrounds the fish tank. So at the last minute, I closed off the door to the office from the foyer side and replaced it with a built in fish tank, and then replaced the kitchen wall between the two spaces with pocket doors. And if I did use it, I would be burning stuff in the kitchen, not hearing or neglecting the laundry, etc and just feel so isolated. I knew I would hate to use it like that and probably wouldnt, and have my laptop everywhere but there. Our new house was going to have my office off the foyer to the left, with a wall between it and the kitchen on the back side. I have trouble with rearranging other ppl's layouts, and it looks pretty close to the kitchen, and for me I want to be closer to the kitchen, but that is just because I know the way I do things. Here is a link that might be useful: architect's site, for reference or larger view It's the craft room in the SL 2009 idea house in GA. Inspiration for home office (don't need one THIS big). (Note, we're thinking of closing the side porch to create a mud room and moving the laundry room to that area instead of upstairs)Īny related experiences would be helpful. Use for office: paying bills, writing letters, laptop OR, do you think there is a better place for this office altogether? Do you have an exposed office? If so, do you like it? I wonder if that would be an issue since you pass the office on the way to the DR. In the plan, there is no door to the office. Is that a usable space, in your opinion? A part of me wonders if it's just big enough for there to be wasted space. I can't picture a space this size, though I know how I'd want it to feel. (though I have thought about trying to cut into that space for a pantry, somehow) With the changes we're thinking of making, the exterior wall would be moving out three feet, so the office would end up beind 7x10. One thing I've been thinking about is the 7x7 office off the butler's pantry.

Cheapest autel drone12/31/2023 Not only does the drone come with an impressive 4K camera with huge flexibility when it comes to settings, but the other additions to the model offer quite the package. » MORE: Autel EVO Max 4T Thermal Drone Review Autel EVO IIĪs far as consumer drones come, the Autel EVO II Pro is one of the best, but it is also the most expensive. Today there are multiple options for all levels of pilots, and each one competes with the best drones like it on the market. It was available starting at $999 and was Autel Robotics’ first step into the consumer drone market.Įver since the release and immediate success of the EVO series, the company hasn’t stopped building similar products while improving all the way. The EVO series was a compact and light option for any videographer / photographer. The EVO series was created to perform to the same or better level than DJI’s most impressive drones at the time. In 2018, Autel released its first consumer drone that was widely available to the public. From a miniature drone for beginners to a massive fixed-wing aircraft, Autel has created products for everyone, but which one is right for you? Autel Consumer Drones Three of these models are geared toward a consumer market, and three are made for commercial and enterprise use.īoth types of drones are incredible for what they are made for, and their designs are easy to learn and use. There are currently six different styles of drones made at Autel robotics, each with a specific design to fit unique customer needs. This can be frustrating when you have a job within an area that is typically restricted, but you have obtained a waiver for a particular time or height to fly safely.Īutel does not have these restrictions on their drones, which makes a pilot’s job more difficult to identify restricted zones themselves, but it allows for freedom when flying in areas that are temporarily accessible for whatever reason. However, DJI and other smaller drone companies may restrict the drone itself to disable it completely in those areas in a technology called geofencing. The FAA restricts drone flights to certain areas due to safety issues and concerns for manned aircraft and people in certain areas.Įvery pilot can apply for flight waivers and documents to allow them to fly in certain areas. 1/2″ or 1/1.Another benefit to Autel drones in the United States market has to do with the heavy restrictions on airspace by the FAA.The three-way binocular vision sensors allow the drone to perceive obstructions in front of it, behind it, and below it, the Nano+ can easily brake to avoid collisions.Īutel Nano can automatically follow any person, animal, or vehicle so you can focus on your activities while your drone handles the cinematic side. Similar to the Hubsan Zino Mini Pro, the Autel Nano+ also features a 3 direction obstacle avoidance system. SkyLink is Autel’s strongest image transmission system yet, which offers resolution and superior anti-interference capabilities. These mini-drones have a battery life of up to 30 minutes and a communication range of up to 6.2-miles (10KM). Both drones weigh less than 250 grams, which makes them super portable and legally to fly in most countries without any registration. While the ‘basic’ (non +) edition is equipped with a 1/2″ 48MP CMOS sensor, the advanced Nano+ version has a larger 1/1.28″ 50MP sensor. Autel Robotics’ new Nano series comes with two camera options.

Td jakes audio book12/31/2023 It was published in 2017, making it one of Jakes’s most recent books. It is one of the invaluable Jakes’s books on leadership that you should take with you. Of all the books from Bishop Jakes, Soar! is perhaps the best T. It is not only one of the most popular Jakes books, but very possibly the best T. There will always be fear and always disappointment in life, but the author here wanted to express his devotion to women all over the world, and if you ask us, he has done just that. This book is about overcoming all the obstacles, problems, and difficulties we encounter, whether it is so tragic that grief has taken our hearts or just a small inconvenience. The story is about a couple who supposedly and outwardly seemed to have everything one could wish for – great careers, faith in God, friends in the church, but when tragedy strikes, how strong are they to weather the terrible storm that was about to hit them? Standing Firmly Woman, Thou Art Loosed! is a book written especially for women. The book is a great achievement and it was published in the year of 1993, spanning nearly two hundred pages. Woman, Thou Art Loosed! is one of Jakes’s books for women, but also one of the best-selling Jakes books. Now, with that said, we can take a look at the best T. The author has also received a Grammy Award in the category of the Best Gospel or Chorus Album in the year of 2003 for his album A Wing and a Prayer. In 1981, he and Serita Jamison finished their nuptials business and have been together ever since. In several years, his congregation had grown exponentially, boasting more than 300 members, but this was nothing compared to what was to come.

Letter scaffold12/31/2023 The first description of Hester notes her "natural dignity and force of character" and mentions specifically the haughty smile and strong glance that reveal no self-consciousness of her plight. There are "fantastic flourishes of gold-thread," and the letter is ornately decorative, significantly beyond the colony's laws that call for somber, unadorned attire. The irony is present in the elaborate needlework of the scarlet letter. On the scaffold, she displays a sense of irony and contempt. The reader first meets the incredibly strong Hester on the scaffold with Pearl in her arms, beginning her punishment. Somewhere during this period of time, their solace becomes passion and results in the birth of Pearl. While not a Puritan herself, Hester looks to Arthur Dimmesdale for comfort and spiritual guidance. When they left Amsterdam for the New World, he sent her ahead, but he was reportedly lost at sea, leaving Hester alone among the Puritans of Boston. She married the much older Roger Chillingworth, who spent long hours over his books and experiments yet she convinced herself that she was happy. What we know about Hester from the days prior to her punishment is that she came from a "genteel but impoverished English family" of notable lineage. With the scarlet letter and her hair back in place, "her beauty, the warmth and richness of her womanhood, departed, like fading sunshine and a gray shadow seemed to fall across her." While her punishment changes her physical appearance, it has a far more profound effect on her character. Hester is only to have a brief respite, however, because Pearl angrily demands she resume wearing the scarlet A. Symbolically, when Hester removes the letter and takes off the cap, she is, in effect, removing the harsh, stark, unbending Puritan social and moral structure. When she removes the letter and takes off her cap in Chapter 13, she once again becomes the radiant beauty of seven years earlier. Her beautiful hair is hidden under her cap, her beauty and warmth are gone, buried under the burden of the elaborate scarlet letter on her bosom. In fact, so physically stunning is she that "her beauty shone out, and made a halo of the misfortune and ignominy in which she was enveloped."Ĭontrast this with her appearance after seven years of punishment for her sin. Hester is physically described in the first scaffold scene as a tall young woman with a "figure of perfect elegance on a large scale." Her most impressive feature is her "dark and abundant hair, so glossy that it threw off the sunshine with a gleam." Her complexion is rich, her eyes are dark and deep, and her regular features give her a beautiful face. Her inner strength, her defiance of convention, her honesty, and her compassion may have been in her character all along, but the scarlet letter brings them to our attention. While Hawthorne does not give a great deal of information about her life before the book opens, he does show her remarkable character, revealed through her public humiliation and subsequent, isolated life in Puritan society. What is most remarkable about Hester Prynne is her strength of character. |
