Rick, That's surely a risk worth taking! On a more serious note, China has a population approximately 5 times that of the USA, and it is still in the growth phase of it's industrial revolution so naturally they will need a higher proportion of engi

All this dicussion of salaries and job losses came to mind when I saw this article. Maybe a competent technical guy disillusioned by the state of the current electronics manufacturing landscape in this country has something to fall back on..........

We assume you're being facaecious. If you think humiliating people drives your organization toward growth, development, and improvement; you're sadly mistaken. Your promotion of fear as motivation develops only one thing - anger towards you and the

We have experienced contamination under flat chip arrays. The lab report is still open but it appears to be dendrite growth. We have been trouble-shooting our process and cleaning equipment. My question is are there any specific design or best p

Everyone has been playing a guess game so far :-) but we don't even know what the lead finish is:-) Even old (Sn-Pb finish) days, the ammount of Pb in the plating would be on a single digit level (just to mitigate Sn-whiskers growth), meaning that th

Well, typical content of Pb in Sn/Pb polating is a few percent (just to mitigate Sn whiskers growth). Therefore, the lead finished with SAC305 won't be much different from those finished with Sn/Pb. You can make one or two cross-sections for sanity c

Yes generally speaking yes if there is not contamination on the board from PCB manufacture. for dendrite formation you also need moisture and voltage during operation of the product. You can see many of my IPC Defect of the Month videos at showing yo

C3 just uses heated DI water that it applies, then pulls back into a disposable cartridge. Machine then applies a 10V charge to the sample & measures leakage current(nA,I think) over time(sec). If the leakage current is high enough/fast enough, you

snip | Ryan, | | The only advive I got is just don't do it!. Dave's right the grain growth in it is pretty bad. the other thing you got to look at is how much heat is the board gonna produce in it's working life..??? and where is it gonna be used,

| Has anyone had any experience with using this alternative plating process? Some board houses are pushing toward this plating. Is there any long term data on this process? Any problems experienced with smt and thru-hole? I've heard tin whiskers to b
