An insulating substrate (10) coated with a thin copper layer is drilled to form through holes (16) and etched to define a circuit pattern (15). A liquid photopolymer solder mask layer ( 1) having a smooth planar outer surface is applied over the circuit pattern and processed to expose ...
First, because the board will be more compact because your design as well is made to be compact. Second, it's more convenient to use, since you can decide where to put space on your board. And last, the board will be stronger unlike those ready made project boards are full of holes ...
After a few minutes(don't be anxious)peel the paper off starting from a corner. There should not be any toner on the paper. Rinse the board in water to remove any remaining paper particles. Step 8: Etching Step 9: Large Boards For larger boards, I place board and print between two b...

Convinced he could find a solution, Kosuga-san assembled a cross-functional team of more than 20 engineers and tirelessly searched for two years to find the recipe, or "secret sauce," for a low temperature solder process that could apply to all devices using printed circuit boards. The ...

Philips is one of the largest consumers of printed circuit boards (PCBs) in the world. To make sure its PCB operations were efficient the company spun-off that business, creating Philips Contract Manufacturing Services (PCMS). Over the years PCMS expanded into other electronics manufac- turing ...
I've incorporated these DIY boards into my IoT projects in two different ways. One way is to create a project-specific PCB using 1 x 8 female headers for the ESP8266 board, just like the Programmer board. The other way involves simply connecting the male header pins on the adapter plate...
The present invention relates to electrical contact terminals and more particularly to terminals for connection to printed circuit boards. BACKGROUND OF THE INVENTION Electrical contact terminal posts are known which can be electrically connected to printed circuit boards by insertion through plated through...
