Dave Thanks, some very interesting articles on that link, it really is rocket science! However this article is a bit of a tease, it tells you how they compared different package types, CBGAs and PBGAs and a fine pitch QFP but does not detail the

Dennis thanks for the feedback. I can confirm we have also had 'black pad' type problems on gold pcbs fitted with BGAs. It can be as you say impossible to detect on Xray. We try to avoid gold pcbs for this reason, preferring horizontal HASL even whe

We have a RAD5 and RAD 8, both of which have the Expanded Range Verifier. Has anyone had success verifying the correct value of electrolytic caps? Our machine stops several times a day for a false failure, and Universal isn't much help. Thanks John

Hi Experts, Anybody know whatis the alternative to the PCBA's barcode, should you don't have a space on your highly populated PCBA ? This refer to the boards' serial number, be it for tracebility purposes or shopfloor data collection purposes. I hav

We are interested on measuring height paste as a control method in our production lines, We are considering using a Cyberoptics equipment but we perform a GR&R for this equipment and it didn't pass it. Do you know a better alternative to measure heig

Did you use the frame grabber software that is available for the LSM? I used one in the past and we also failed the GR&R we then installed this software and it became very consistant unfortubately I cannot remember who sells this software. Anyway,

Like other things, the more you pay, the better the gage. I'm not sure which Cyberoptics unit you're considering, but LSM has a lousy gage [R&R ~25%]. We use a microscope with lousy gage that costs waaay less than some laser guided thing. Search t

Ok Guys, I really appreciate your answers. we are using the LSM 300, so I'm going to check about the software you mention in order to check if this could help.If you have any other idea, please let me know. By the way, I didn't think that somebody w

I am looking for defect rates on hand soldering. Specifically - I have a large number of wire jumpers that need to be hand soldered across two boards (connectors are not an option). I am looking for a defect rate so I can perform a cost analysis in

Does anyone have any information or experience soldering of class 3 products with WS fluxes. We are currently leaning toward Alpha WS609 flux, however the customer's interpretation of J-Std-001C feels that type 'H' fluxes (WS) are not allowed. Any
