[Techtoolslist] tinning ICs?

[david grohowski]

about 15 years ago I used to buy refurbed ram and cpus from a company and I have never been able to duplicate their quality.  their ICs' legs were clearly dipped into something like a solderpot.  I have one with new solder bar and even if I clean the legs manually, then wash or clean with alcohol, etc, it never bonds like theirs.  maybe in part it's because the parts I was trying to refurn were in bad shape to begin with.  you arcade guys know exactly what I mean.  anybody had good success stories?


thx
