Hello everyone, I am curious if you label your solder paste jars with additional label. We want to use our own label showing when the paste was opened and how many hours it was exposed. Any thoughts will be appreciated. Thank you!

We are required by most of our customers to apply a serial # to the boards that we build. As the PC boards have been getting smaller and open areas on the board are getting scarce we have been forced into using smaller and smaller labels. I am lookin

I'm curious if anyone has figured out a clever way to errorproof this. We're exempt from RoHS so we have mostly SnPb products but some Pb free ones at customer request. Of course, we have methods to control moisture sensitive parts, but I worry tha

2D codes take up much less real estate so that might work. Something else we did was to go to CO2 lasers and mark directly into the solder mask. Underlying copper gave adequate contrast to the green mask. Much more of an investment, but works grea

Hi, thanks for your answer. I was thinking to go even deeper by counting the hours the paste was exposed, but it probably doesn't make a lot of sense, especially considering the fact that my operators will add paste when the level goes too low. I wi
