Short of locking them up and checking them in and out (and writing up your operators for not checking them back in at the end of a shift), I dunno. In short, I think ya gotta be a tool Nazi. We only use hand tools (assigned to the operator's pers

At the OSHA training institute, our instructor stuck an electric drill in a bucket of water to demonstrate what proper grounding will do. Personally I wasn't going to try it. All our fluxes are no-clean, and are IPA based. Granted we used aqueous

Use a PCB fab house that is capable of "Conductive Via Filling" is the way to do it right. A conductive epoxy is used to fill the drilled via PRIOR to final plating. After final plating, the surface of the "Filled Via" will appear to be the same as t

I have a brand new X/Y/Theta table for an SPM(The one that uses magnetic supports) that I would like to trade for an older version table.(The one that has holes drilled and tapped in it.) the one I trade for has to be in good condition. No stripped h

Is anybody using via-in-pad under a BGA successfully? Is this a specialized capability, or do most board houses have the capability to do micro-via's? How small does the via need to be in order to avoid solder wicking? I understand that in order for

That machine came to us about 5-7 years ago! I'm trying to make it working again, but I need someone who knows something about it. I think that machine works well. Its as good as new, but i'm not sure about the software. When I try to run drill tab

try using drill holes.. i have used these in the past, just recently we used them and placed 0.5mm pitch devices fine.,. This should sort you out for this batch but get onto the Customer and tell them you need fiducials for reliability on placement.

We had that problem with our printers we just drill and tap the top end of the stop and put a short screw in to allow us to adjust the top height of the stop and catch the board. Be careful not to make it to long or to could restrict the board from l

Hi Folks, When temp profiling bga rework how important is thermocouple placement. Have read that holes should be drilled from board underside into ball to accomodate probe (isn't theory wonderful). Probably ok for high volume rework but for 1 or 2 of
