I can't offer much advice on acceptible rates or #'s. From a process standpoint, most of your bridging or insufficient originates in your printer. Look into buying dedicated tooling specifically designed for the build. We use "h-towers" on all hig

Inspecting for plating problems shouldn’t be part of incoming inspection. Your board manufacturer should have the appropriate process control. I shouldn’t have said barrel cracks but plating skips. Plating skips are caused by dull drills or a too hi

We are currently using the F1. We've had it for a couple of years now and overall we are happy with it. We did have some issues with the software crashing but after replacing the PC several times we seem to have found a stable platform. Also the conv

Fortunately for me, we do not use Repair Plus so I can't comment on how well that works with the newest software. I have been thinking of doing the html saving though so my engineering and management team, especially those located off-site, can revi

Thanks davef Bridging:- There is no heat sink on the BGA, the heat sink will be fix after relow. I do believe paste had something to do with it, but currently this defect didn't appear so oftenly, so we think that the main root cause is not from the

Hi Dave I agree with the 2nd point (sloppy process management) if the failure rate is higher than 5%. But this is 0.083% case, and only happen once in the blue moon. As I study about the re-flow profile for the last whole week, current parameter se

Ok Guys I need help in justification of Converting TH boards to SMT. We do quite a bit of I/O controllers using sockets and chips, and our biggest defect issues are bad chips. I am preaching to convert these boards over to SMT, however my designers

the cause could be moisture in your pcbs. To check it...pass some bare pcbs through your reflow oven (this is a simple way of drying them out a bit), then paste and place and reflow as normal....if solder beads disappear then the pcbs have too much m

Has anyone had success utilizing the lifted lead/ height checker feature on a Mirtec MV-7L. We recently had two separate events where the machine did not detect a lifted lead using the ic/bridge inspector. The soldering results came back with out def
