Hi Ken, Our product is consumer, although our product is sold on it's reliability. We run a low volume high mix throughput. Any ideas on timescale for the Ag leaching? Sounds like it could be a safer bet to use Imm Sn boards with the Sn/Cu/Ni bar w

Hello, a - does any one of you have experience with PCB finished by SN100C (SnCuNi)? SMT single side? SMT double side? SS/DS plus PTH? b - if yes, what about compatibility with different alloys (ie. SAC)used for SMT or Wave (different me

Hi Phil, If the areas that are "turning gray" are masked, it would lead me to believe that you're simply oxidizing the SnCuNiGe finish on those areas. It's unsightly but not an actual defect. I think it's simply the biproduct of using SN100C as a s

Hello Greg, Glad to hear your success with the SACX0307 copy. By the way, does the P mean it contains phosphorus? Does yours also contain bismuth like the SACX0307 (according to their plumbing solder patent for X0307)? In response to your discussion

Hi, We are Scottish manufacturing company considering a move to Immersion Silver finished PWB's from HASL. The driver behind it being the RoHS and WEEE legislation in Europe at present. My question is... We plan on using a Sn/Cu/Ni solder bar in o

I tried some SN100C from AIM... On only one array. It flowed well on the chips but did not like the finish on the SOT23's on the board. I did not have enough arrays to mess around, so we switched it over to SAC305 and had no issues. I'm guessing w

We don't do any wave, SMT only. We did not have to change apertures for lead free, we use the same stencil that we did when we ran water soluble with pb. This I think might be dependant upon your current design of both pad and apertures however.
