Hi its normally down to the state of cure of the resist type not the actual type be it matt or gloss. If its not cured correctly it will produce solder balls. Pending where you are you could try our 35-41 or new 35-41-30 flux this will reduce the pro

Hi Andrzej, I guess you mean peelable solder resist. Good idea to try during R&D, but certainly not a solution on production floor. Also, few constraints to be considered such as presence of entrapped air between component and solder resist, the natu

Hi, I need a wear resistance PCB finishing over bare copper (If exist!), the surface have a moving part which slides over it and bare copper as a surface is not good enough. I'll apprechiate any information. Thanks Roni

Does anybody have any information regarding the plus's and minus's of both copper and solder resist defined lands?

Hi, Did anyone experience a problem with electrically conductive silver filled epoxy is resistive due to galvanic reaction? I'm having this problem when attaching components to Ni plated housing while conducting an experiment to cost reduction for Au

Hello there, Wondering if someone out there can help. I have an electronics package housed in aluminum that needs to resist 100K rad of radiation. Any suggestions on how to tackle this? Thanks in advance. Charles
