Phil is wrong. In the real world, we know that part mfgers have not changed every one of their parts to make them "high temp". They just changed the plating. Anyone who thinks otherwise, has never run a profile or touched a warm board coming out o

In passives I dont know if anything changed at all other than the terminal plating. As for Active components there has been much engineering done to allow for the extra heat needed to liquify say SAC305 or other lead free pastes without damage to th

Hege, Yes. Good info. We have other products that run lead free process with known non-RoHS compliant components. All of these are using LF process compliant fabs however so this is the first time we have been in this position. Thanks.

Yes. You need to educate your customer... On a side note, hopefully these boards hasn't gone through wave over your LF solder pot.. This will contaminate your solder pot and won't be cheap to fix it.

Bronco - Yes. We thought that far ahead. No a good scenario, for sure.

Anyone doing consigned work in the EMS industry has had this issue, I'm sure - Customer says they want lead free processing at the quote stage - PCBs they supply are tin/lead HASL. In this case, no HDI components and no BGAs. What is the latest acc

Hi Johan, As a Asian board supplier - I would not recommend using Lead free hasl on any product that has BGA, you would be just looking for issues, flatness being the main. I agree with one of the other replies - Your purchasing dept. should not be

1. (NCMR) Non Conforming material report to your customer if you have signed up for a lead free job. Send everything back and tell him to replace the entire lot with correct material. or 2. Request a Change order from your customer, changing the

Hi, i tried to search but am hving trouble finding discussions on leaded parts being used in leadfree soldering process. So, i need some inputs from expert members here. Will it work if a component plated with SnPb will be used in a lead free sold

Amol, I thought I answered your question in another thread, dude! Anyway, to re-iterate. Yes, I was able to pull it off a hybrid profile. The LF BGA passed tensile testing, but no, it wasn't thermally cycled or stressed first to expose any latent
