I'm sure they'd be open to acrylic, as it'll provide a nicely hardened finish for them once cured. The real question is would it be workable to do what they're asking. That is, thick enough to coat the board when we dip it in without all slopping o

Two things ... A friend in the contract coating business said: "... the board is not being baked out long enough, 30 min is certainly not long enough depending on how many layers this board is, as the vacuum (from the parylene process) is pulling t

Oh yeah, so we have a auger valve similar to that on one of our other machines that we use for dispensing SMT glue, and solder paste also. We have a conditioner that we flush it with at EOD when in use, then we just let it sit idle with the condition

Leaded HASL on small pads can be quite difficult to print on...the HASL tends to be domed rather than flat..and that can affect print quality...you really need a perfectly flat pcb pad to print paste on when you are assembling 0.5mm QFPs. If the pcb

Chris: I can't a semi-auto dip tank being any faster than manually dipping. Better control - yes. Less messy - yes. Other stuff Graham mentioned - yes. Have you discussed your goals with some of the used equipment folks listed in the archives?

We currently use a tool that we have developed and sell that can provide real time feed back on OSP coatings. With OSP it is a case by case basis on how many times you can reflow or apply heat before it becomes detrimental. Also, Depending on your pr

These types of foil kits work just fine as long as they are used before expiration. Scraping off the epoxy coat gets a little tough on fine pitch pads and etches. I have always like to use a solder sample board to retrieve my bits & pieces from whene

Is Mil-I-46058 still an active spec or has it been obsoleted by the Feds in favor of IPC specs? I have an internal process document that is based on IPC requirements, but a customer wants me to use their specs that are based on the mil spec. I am ho
