Q: If you do not use a selective wave pallet does this not leave the possibility of solder flowing up thru the Via's on the board? A: No. Your board house can cover your vias with solder resist. Your board house can plug the vias. You can cover t

Graham Naisbitt is definitely an expert on conformal coating, he has posted answers here for years. Check your material to see what the cure mechanism is. Most urethanes need moisture from the air to cure, the higher the relative humidity the faste

Hi GS, We are contract manufacturer for small series of electronic equipment fully trained for SMT.Making mostly RF with only few QFPs,TSOPs...SMT machine assembly was made by local subcontractor when needed. Recently we acquired two Juki 730 machin

When I started using our ESV-304 the CAD converter would crash if there was a part already in the library with an alias. With the two cameras we can only put parts from one camera in the library. And our current library would be totally useless with

Histroically we have designed our pcb panel configurations around the v-score format. The QA Dept of our company is is suggesting that we revert back to tab-routing as away to avoid damage to senistive components like large package ceramic capacitors

I just went through the same problem. We have an inductor that is made with a bundle of 30-strands of Litz wire that is vaccuum coated with varnish, and have the ends of the wire bundles tinned that we have to solder to SMT pads on the board. The ind

for years we have all delt with the choices of endless products to use as flooring to create an ESD safe area for electronics assembly, I have spoke with "ESD TECH's" in the past that have told me a "clean / Bare concreate floor" provides as much di

As I know, the encapsulation effect occurs only with rosin based fluxes. So if you have a PBA soldered using RA Flux, you should either wash it well, or leave it alone and it will be safe. For NC process the story is different because there�s no re

Although rather expensive, you have to realize they had to go through extensive testing to prove their product safe. This probably cost them extensively. So once the formula has been deemed safe, they just pass this cost onto the consumer. Not to
