Frequently Asked Questions
Leaded PCB assembly usually refers to PCB assembly using tin-lead solder, also known as SnPb solder. In manufacturing, it commonly means the board is assembled with leaded solder alloys such as Sn63/Pb37 or Sn60/Pb40 instead of lead-free solder.
Yes. In most cases, leaded PCB assembly, SnPb PCB assembly, and tin-lead PCB assembly refer to the same type of assembly process using tin-lead solder.
Yes. We support Sn63/Pb37 and other common tin-lead solder alloys based on project requirements. Please confirm your alloy requirement when submitting your RFQ.
Yes. Our SnPb PCB assembly service is generally intended for non-RoHS or selected RoHS-exempt applications. Customers should confirm the compliance requirements of their products before production.
