Specific solder types

The current, lead solder (63% lead, 37% tin) has the following Kester part numbers: Kester 331 Organic is part number 24-6337-6401 (0.020 dia) Kester 245 no-clean is part number 24-6337-8800 (0.031 dia) There *are* lead-free versions (containing Tin/Silver/Copper) that are also '331' and '245' (these numbers refer to the flux inside the solder). So, when looking to buy, use these 24-xxx-xxx numbers in *this* email. Paul S.
