I am having a problem remembering what temp to pretin components at. This is for SN63. I thought I used 450F, but this company says 500.

We used to use 260+-5C (500+-10F) for Sn63, now we use 240-260C (460-480 F). You probably could get away with 232C (450F) in all cases, since there is no thermal mass to a lead being tinned. We keep our tinning temperature the same as our solder pot temperature, because we haven't figured a way to justify a different temperature.
