Dont't bother to answer real idiots! I can relate to a similar problem. We also use SN100C alloy and the solder pot get(got?) contaminated with the alloys from the SAC305! How can this be? Strange thing happens during the soldering process, and it o

Hi Grant, I understand your concerns about the reliability. It depends what the boards are use for. For ex. if it is in a telecom system market where lifetime and reliability is a big issue 10-20 years lifetime (our customer reqs. that at the system

Thank you for the quick reply! Actually, the "type B" I referred to applies to a flex cable that can be found in this page: http://www.tennrich.com/trtw/cabling_3.php It is a reverse Engineering project and, from what I can see, there is, indeed,

Here it is Steve Here's a (427 page) EPA report on Solders in Electronics: A Life-Cycle Assessment http://www.epa.gov/opptintr/dfe/pubs/solder/lca/lfs-lca-final.pdf If you look at page ES-16/table ES-4 and ES-5 it appears that SAC alloys have a hig

we have recently been having trouble with our PPS capacitors on a couple of our boards. these boards are RoHs and the Parts are RoHs compliant. these boards first run through our reflow then a batch washer some through-hole parts are placed and then

hi, the last post on pad cratering dates from 2012. We have (likely similar) problems with a RoHS 783 solder ball BGA size 29x29mm^2 (organic package BT), pitch is 1mm and solder ball diam is 0.5mm the field failure is after 12 months, almost exclu

I have received information from the European Commissioners Environmental group that automotive electronics are not covered by WEEE (waste electrical and electronic equipment 2002/96/EC) or RoHS (reduction of hazardous substances 2002/95/EC) because

I'm not a politician but it sure looks like protectionism and a short-term economy boost for Europe. Don't forget that lead-free for the electronics is a European directive, USA and other countries (exept for japan) have non of this on there agenda (

The directive is called RoHS. Meaning that is not only the lead that is the issue. The materials need to whithstand a hihger temperature, not only delta T is an issue (but huge). Moisture sensitive devices: how to handle these? You will see an increa

Yeah, adopting is the right word. In this new lead-free era spec.'s are made to stay within the scoop of the RoHS directive. The driving force for spec.'s should be reliability. Did you see any impurity level spec.'s yet in wave soldering for Cu, Au,
