I think its can be good alloy for  PCBs HASL plating.

If someone against, pls explain why not.

Hi Kerry - Dr.  Hwang's book titled "Environment Friendly Electronics:
Lead-free Technology", ISBN 0-901150-40-1, Chapter 6.2, contains a
significant amount of data on the 58Bi/42Sn solder alloy which may be
helpful in your efforts. Good Luck.

Hello esteemed Technet,
      I am looking comments on what you would consider the advantages
and
disadvantages of this composition of this solder paste. (58Bi/42Sn)
Lower MP.  138 Degrees C.
Lower fatigue resistance
Wetting to ImAg??
Wetting to ImNiAu??
No Clean?  Residue?
Intermetallic Formation?
Mixing with 63/37Sn?
Our application is an RF board where we would use this paste post Wave /
Hand Solder.
Any comments appreciated.

Cheers,
Kerry
