Good one chunks!! Great way of proving a point With lead-free, engineers walk on thin ice and sales people are in heaven. If a flux can't handle an increase of 30C it wasn't a good flux to begin with.

It goes to show, EVERYONE (Equipment OEM's, solder paste, flux, wick, etc) is benefitting from this Lead-Free legislation. It's even created jobs in the US, and has taught many a Process Engineer the basics of soldering and profiling.

Since that LF debacle is doomed for disaster anyway I wouldn't be surprised to see one on the market soon. Wouldn't that be something??

You're living a Dilbert cartoon! Thanks for giving me a Friday laugh...knowing that I'm not the only one dealing with some of these challenges - although it sounds like you got more than your fair share of them.

You will not get a "visible" solder joint on this part. The joint is under the part. If you can magnify the part, you'll see the exposed lead is not plated.

Chunks nailed it. You should not expect to see a perfect side fillet on this part, especially using no-clean, it's probably bare copper, hard to wick solder up the side of the lead.

Part is most likely a QFN package. IPC-610-D has standards on solder quality for this new type of package.

one point to remember is to have a large stencil reduction on the thermal pad, you need to reduce the solder volume by about 35%, if you don't you risk the solder from the thermal pad shorting out the other leads or the solder volume causing the comp

Guys, Just to let you know, I followed the recommendations from the supplier and we have very nice solder fillets now. Thanks for all your help.

Several weeks ago, there were some postings about a new product for reducing dross in the wave solder pot. It was, I think, a liquid. Both for Tin/Lead and lead free solder. Anyone remember who this vendor is?
