I'm looking for feedback on processing PCBs manufactured with 'immersion' or 'white' tin surface instead of HASL. In perusing the archives, I notice there were pro's and con's to the process a while ago and I'm wondering what the current thoughts of people using the process are. Any specific process recommendations, reliability, etc. would be appreciated. Thanks.
