We looked into OSP for lead free. OSP is less costly than ENGI.

We use the e1 designation/marking on either a label or inbedded in the PCB.

Try raising the part off the board a little. I bet this will help.

anyone have any experience with lead-free HASL?

Maybe your solder mask supplier can provide additional background

does anyone have experience with reflow of Micro SD cards to PCB@ lead free temps?

hi experts, need more info on what's happening with the LPI Solder Mask on an FR4 PCB during reflow of both Leaded and Lead Free Process? Do they become soft as well while exposed to the extreme temperatures? regards,

All, We know that incomplete immersion silver could potentially lead this creeping corrosion. Is there any way to check bare PCB for incomplete immersion silver coverage, especially on the via hole area? Thanks, Sean.

Hi Syed, I'm a PCB engineer from China. First:Immersion gold surface finish is the best for PCBs. Second:HASL(Lead-Free HASL) Then:HAL(with lead) The cheapest surface finish is OSP(After 15 days will be oxidized)

I totally agree with you when whe talk about a lead-free process. In my early comment I thought we were talking about a tin-lead process with the pcb pb-free, when the solder paste limits should be respected. That is the motive the temperatures I sa
