Frequently asked questions
Is SN42Bi58 suitable for all boards?
It melts at a much lower temperature than standard SAC lead-free alloys, which suits heat-sensitive parts. Joints may be less tolerant of heat later, so check the requirements of your application.
How should I apply the solder paste?
Apply the paste to the pads using a stencil or a dispensing method, then heat with hot air or a reflow profile matched to this low-melting alloy.
