I have a question (s) on ESD- all related to use of wood in a typical PCB Assembly line: 1. How a wooden mini stool if used for holding tote box ( card board with static protecive coat, black color) can affect static sensitive devices inside the tot

Hi Antonio: You clearly have printed excessive amount of solder paste on the pad. You can reduce the amount of paste by one or two methods: 1. Switchover to 5 mil thick stencils. 2. Change the design of your stencil openings (at the discrete compone

Jason: Wave soldering is the coolest thing!!!! First, so, what�s the chemical analysis of this white res? Can you point us to either tin, rosin, or something else? Second, how do you know that you are making these white residues? Could your boar

Donnie is correct. "NO-Clean" doesn't translate to "no-residue!"..... who's giving you hassle about this - your ICT guys??!! Residue remaining on your PCB substrate is a function of many different things - flux deposition, solder mask (glossy means

OK, lemme take a different angle on this, �cuz I forgot to touch on this when I first responded. I mentioned a study ["Evaluation of Low Residue Soldering for Military and Commercial Applications: A Report from the Low-Residue Soldering Task Force"
