I am currently weighing up my options for resistors that will be fitted to a fully assembled PCB (PTH&SMT). Do I omit the stencil apertures leaving exposed pads (ENIG) so they can be hand soldered with fresh solder. Considering shelf life for soldera

Heat above 53 Celsius kills covid viruses according to the WHO: https://www.who.int/csr/sars/survival_2003_05_04/en/ If you want an added measure of safety, you could bake your boards before packing them. Fundamentally its going to be an issue of

Hi, Our assembly process involves applying Kapton tape to the back side of our device, a laborious cutting and sticking operation. We are scaling up from "cottage industry" so I'm interested to know if you can buy Kapton shapes on a reel cut to our s

How long have these devices been out of their sealed dry packs? Did you receive the devices factory new or from a broker of such parts? What may be happening is that moisture crept inside the device and there requires the parts to be baked before you

Almost all the people here buy boards with the metal already plated on. We are mostly assembly people. The ones you really want to talk to are PCB fab people. And if you want to look into plating PCBs, I would suggest you look up Black Pad. It hasn'

I would question your motive "There's no way that I feel comfortable shipping boards after a selective without cleaning them, the amount of flux on the board is significantly more than from SMT". 1. Who said that residue should be cleaned and why? O

Thanks, I have read (almost) everything I could find on UIC's site. The problem I had was that I never before tried to perform FJ calibration, so I did not know how it normally works. Anyway, I figured out what I did wrong and managed to calibrate t
