Hi Yannick. This is an issue that we are just recently getting into but here is some ifo that I have gathered so far. I have seen/ used 2 different rework machines. The one we have bought is a 'PACE TF2000' which was at the lower cost end of the mar

Dye and pry is frequently used on BGAs to determine if there is a crack at the board level or component level interconnect. C-SAM will show internal delaminations of components, not sure how well it would work with solder joint cracks. You can also

You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl

We've never heard of seen of such a thing either. We tried a clean sample board and applied con coat. Same process through out and we saw nothing. After speaking with the original operators who was curing the boards he had left the boards much longer

BGAs and QFPs packaged in Trays are oriented with Pin 1 or corner A1 oriented towards the Pin 1 identifier on one corner of the Tray, which is usually identified by a chamfered corner. The Trays themselves are usually governed by JEDEC Registered Ou

I recently had the same problems, solder bridges on every thing I made, different customers boards, etc. I wave with no-clean flux. As I sorted out problems (pin holes, blow holes, splatter, etc.) I found a lot of variable factors. I changed flux,

A question for you all! Back in the good old days, we didn't always know how clean was clean. Much has changed. Much hasn't. My question concerns cleaning under, through, and around tight spaces. Way back when, we could not clean under 20 mil pitch

We have a potential new customer who has special PCB requirements. I do not know a lot of details at this point, but have several questions. One of their assemblies has within it , a MID, Solid foil layer, completely isolating one side of the PCB f

Tsvetan that really is an amazing machine. I have looked at it but assumed it was way out of my price range. Is it really possible to get a new machine with 50-60 feeders for under $100k? That sounds like a steal. What is the maximum component heig

I don't get it. The liquidus of 80Pb/20Sn is like 280*C. Your reflow temperature got nowhere near that value. Where did that material go? Is it folded back under the component? Disappeared? Was it ever there? Ask someone while analysis tools to hel
