Thoughts on Removing Potting Compound from Electronics

Many electronic assemblies, especially those in automotive and marine industries use potting compound which act as a protective coating. This video looks at non-re workable compounds which are especially difficult to remove…. a property of many (all?) epoxies is the glass transition temperature which can be exploited. Also looks at the need for a fume hood and respirators with organic vapor cartridges!

Multilayer FPCBs led the FPCBs market, and is supposed to retain this trend through the entire forecast period of time. Nevertheless, the rigid-flex FPCBs segment is predicted to witness considerable boost in the possible future, owing to the small size and low power use.

Among end user, electronic products overpowered the global market in 2015, accounting for about 30% share. Even so, automobile electronics is predicted to expand at the maximum CAGR of 10.7%, due to surge in need for long lasting units with boosted efficiency.

Asia-Pacific was the primary revenue contributor in 2015, and is supposed to keep up its prominence in the future, on account of surge in number of electronic applications. Furthermore, movements in electronic products and industrial systems are anticipated to elevate the FPCBs market growth, particularly in the Parts of Asia, for instance China, Japan, Oceania, and also India.

Flex PCBs are greatly successful interconnectivity solutions for an array of electronic products with complicated circuits. Furthermore, they furnish a great number of edges that include high efficiency and decreased system repairs and maintenance. Multilayer FPCBs represent nearly 30% of the total FPCBs market, on account of their resilience and high efficiency. Plus, sizeable need for electronics applications and buyer shift towards compact printing to accomplish better efficiency are anticipated to fuel its consumption in the electronic products, motor vehicle, together with other market sectors, states Jeshin Jayamon, Research Expert, Semiconductor & Electronics Research, Allied Survey.

LAMEA is believed to increase at the maximum CAGR throughout the analysis period of time, on account of surge in portable appliances and rise in the consumption of FPCBs in motor vehicle applications. Furthermore, technological breakthroughs to defeat power loss problems in extreme situations are anticipated to give lucrative possibilities for market competitors before long.

Main Results Of The Flex PCB Industry

In 2015, multilayer FPCBs dominated the global FPCBs market, as to revenue, and is anticipated to increase at a CAGR of 10.7Per-cent through the forecast period of time.

Electronic gadgets directed the market, accounting for nearly 30% market share in 2015.

China was the major shareholder in the Asia-Pacific FPCBs market, accounting for around 34% in 2015.

The key competitors operating in the FPCB market have adopted new product roll-out as their favorite strategy to broaden their market foothold. The key competitors profiled in this report incorporate NOK Corporation (Nippon Mektron Ltd.), Sumitomo Electric Industries, Ltd. (SEI), Fujikura Ltd., Multi-Fineline Electronix, Inc., Zhen Ding Technology Holding Limited (ZDT), Nitto Denko Corp., Interflex Co., Ltd., Career Technology, FLEXium Interconnect, Inc., and also ICHIA Technologies Inc.

PoisonTap – exploiting locked machines w/Raspberry Pi Zero


PoisonTap – siphons cookies, exposes internal router & installs web backdoor (reverse tunnel) on locked/password protected computers with a $5 Raspberry Pi Zero and Node.js.

When PoisonTap (Raspberry Pi Zero & Node.js) is plugged into a locked/password protected computer (Windows, OS X or Linux), it:
– emulates an Ethernet device over USB (or Thunderbolt)
– takes over all Internet traffic from the machine (despite being a low priority network interface)
– siphons and stores HTTP cookies from the web browser for the Alexa top 1,000,000 websites
– exposes the internal router to the attacker, making it accessible remotely
– installs a persistent web-based backdoor in HTTP cache for hundreds of thousands of domains and common Javascript CDN URLs, all with access to the user’s cookies
– allows attacker to remotely force the user to make HTTP requests and proxy back responses (GET & POSTs) with the user’s cookies on any backdoored domain
– does not require the machine to be unlocked
– backdoors and remote access persist even after device removal

Best 5 Raspberry Pi Zero Electronics Projects Which Make Use Of Its Compact Measurement

The Raspberry Pi has long been the hobbyist selection for Do-it-yourself electronic projects. The Raspberry Pi Zero, which is close to the size of a stick of chewing gum, is fairly low priced and has it’s own special application scenarios though. There are ten of our most-liked projects that utilize its size.

1. Stuff a Raspberry Pi Zero Into an Old Style Game Controller

It’s well known the Raspberry Pi makes an fantastic DIY video game console. The setup process merely demands a couple of minutes, and the Raspberry Pi Zero is very efficient at handling dated games from the Super NES period and earlier. The whole project is more enhanced when the whole system is inside a controller.

Good example (ahem), this project operates on a Super NES controller, this one tackles the NES controller, and this one uses that good old original Xbox controller. However you attempt to undertake it, you will get a pretty slick tiny DIY retro gaming console you could tote around anyplace.

2. Construct a Small Dongle Computer

While the Pi Zero makes a great tiny computer as it is, it makes a far better dongle computer. In this manner, you can attach it to every other computer you have, then it will tether itself directly so you will never have to add in a USB or any networking.

One of the benefits of this project is the fact that you no longer need yet one more computer mouse, display, or key pad lounging around. Simply jam in into your normal desktop computer and you’re fine.

3. Build the World’s Most compact (Probably) MAME Cabinet

MAME cabinets are terrific, but they’re massive. For the complete opposite approach, you’re able to make use of a Raspberry Pi Zero to make one that is roughly as small as the Pi itself.

You will need a few items to help to make this sucker work, including a 3D printed case, but in the end cabinet is completely functional, which implies you will have the perfect desk accessory in the office.

4. Build a Motion Sensing Camcorder


The Raspberry Pi is almost certainly a good quality motion sensing camera, but the low profile of the Pi Zero can make it better yet.

Employing the Raspberry Pi Zero, your motion sensing camera has a quite smaller foot print, that means it can go in even tighter spaces. One example is, this one mounts to your window with a couple of suction cups, which is about as light and portable as it becomes.

5. Play Any Simpsons Episode (or Any TV Show) Arbitrarily

When you’ve ditched cable and gone full streaming with your media, you’ll probably still miss the days of catching an arbitrary episode of your most enjoyable TV show. The Raspberry Pi Zero can bring that back.

In this project, they use installments of The Simpsons stored on an Micro sd card. With a custom script, you could mouse click a button and it plays a chapter arbitrarily. It’s possible to increase any media you like here, including various shows if you really wanted, but The Simpsons make the perfect choice.
