Hi, What's the best process for going lead free? Ordering lead free parts and using them with current paste, and then once all the parts are lead free, moving to lead free paste as well? Then the wave will be fun to change over. What a nightmare th

Hi Imtiaz, Can you give a brakup of the 23 components and their end mettalurgy ? Chip ?? QFP/TSOP ?? BGA ?? Aluminium Caps ?? this will determine whether you can do it or not

Imm Silver and Voiding

Electronics Forum | Mon Jun 26 23:33:20 EDT 2006 | KEN

We saw this condition over 3 years ago. It sometimes is called "champagne bubbles". The intemetalic formation is interrupted due to the micro voiding reducing mechanical strength. I discovered this on lead free test vehicles for a major computer

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

Well, most of the capacitor are thru hole, then pcb's goes to adhesive process upsidedown to continue SMT process in which , maximun tempetarure is 120�, so temperature is not problem. About SMT capacitorS, I will check temperature specs before mount

From technical point of view: it should not be a problem to mix Pb with Pb Free components soldered with a LF solder process. You have to take care about the max temperature allowed on your Pb components and make sure they can withstand the higher

Hey guys, Anybody having trouble with increased false contact issues in ICT after switching from lead to lead free? Our test guys keep trying to imply that the flux residues are a problem (we're using Alpha EF2202), but as the soldering process eng
