Hi all, I'm working in Military Production and then, We have an exception about RoHS (LEAD FREE), but, because we use "normal" components, in this moments, a lot of components have LEAD FREE terminations, and we think that after of 1st July, we wo'nt

Well thats what i was thinking of doing and i am not worried about the designer of the PCB. He truly is a dick and i have had many fights with before about wave soldering pad sizes yet he insists he is right but i change them anyway and send the orig

Our ICT Guy here at my company loves to use lots of via holes as test points - via holes which are 0.040" diameter, and spaced at 0.004" edge to edge spacing! He doesn't like to tent the via's either, so I always battle via-to-via shorts at the wave

Get a book on effective complaining. Gerbers is not a good way to program. Matching up the designators is but one headache. At the very least try and get centroid data. But try for ascii cad files. Are there any programs that generate gerbers but ca

*** New related Question*** Thank you for your suggestions. Unfortunately it is still not working though. I have noticed at the top of the "General Purpose I/O Chassis" that a red LED next to PCB location 0 is permanently on. But this is not on on o

Hi Brad, I don't know if this helps, but we had a policy of not accepting x-outs on rigids, and of max 10% per panel on Flexy boards (as long as the local fiducial was blacked out for the bad board) I'm always suspicious of x-outs as it points to pr

I have been using the Loctite Multicore WS200 with great results for the last two years. We also use the lead free version WS300. I like the flux chemistry (which is the same for both products); it really withstands long soaking times and with very g

Mark, I am having difficulty picturing exactly what you are doing, but I hope this helps. We occasionally use jigs through SMT, usually because the board is too small/thin to fit the smallest rail width. In such situations, we normally make the jig

You didn't explain exactly how you are reworking the BGA and at what point the pad comes off. Assuming it's from an iron... The biggest cause of lifted pads is too much heat. Whether it be the iron temp or the amount of time the iron is on the pad

Hi I am using selective soldering to dip soldering the connector pins to the PCB and would like to know your experience: a) Is there a recommended dip or dwell time for the dip soldering? b) How do we improve the solder coverage in the TH? c) How t
