Primeiro imprimia o desenho da placa numa folha de acetato. Essa folha era colocada por cima de uma placa foto sensível e colocada sob luz UV durante uns minutos. De seguida essa placa era submersa numa solução com soda caustica para retirar a pelicila foto sensivel que ficou “danificada” com a luz UV. A placa […]

What do PCB production and fake fingernails have in common? They both use UV light sources of high intensity and, as luck would have it, those light sources have exactly the same wavelength. Only the ones for PCB production are usually quite costly and the ones for fake fingernails are a bit more competitively priced.

Manual intervention to a PCB is usually always visible. With modern „No-clean“ fluxes it´s not that obvious as in the past. But still it doesn´t make resulting look of a PCB better. However, probably more important is the fact, that soldering residues are a potential risk, especially in humid environment – as they may cause
Even your PCBs can look professionally Continue Reading
In this tutorial Dave explains what a PCB spark gap is and how it can be a useful zero cost addition to your PCB layout to help prevent ESD damage. He shows how to easily design them into your board and calculate the approximate voltage rating. And of course has some fun applying 5kV to

Quite by accident I came across a long time ago on video in YouTube, which focuses on domestic production of PCBs. Personally, I am convinced that it is better to perform the PCB in a professional company – you know: aesthetics, double-sided layout, descriptions, solder mask, tin holes etc. But for small, home projects, not

(This tutorial has gotten really popular recently, and I’m very pleased that so many people are interested. I learned all of this stuff while working on my first PCB. If you’re interested, I’ve started to sell the most recent version of my Arduino ProtoShield. If you’re making a shield, have fun and good luck!. If

Sorry, but I hate cleaning windows, is one of my unfinished business as usual, but I had to do (at least) every time I wanted to etch a circuit board printed by traditional (and perhaps unorthodox) of stick it in cellophane and let natural light do the work. Lo siento, pero no me gusta limpiar
