Why do You Need Lead-Free PCBs

  • The REACH and RoHS Directive mandate the electrical and electronics products to be free of hazardous chemicals. PCBs, the core in hardware manufacturing, should be lead-free if your boards need to enter the EU and most of the rest world.
  • A lead-free PCB/PCBA has a lead concentration smaller than 0.1% (1000ppm), and other hazardous substances PBB, PBDE, DEHP, BBP, DBP, DIBP, Cr 6+, Hg, Cd all smaller than 0.1%.
  • Exposure to lead brings permanent health risks. Nowadays, most OEMs require circuit boards to meet lead-free standards.

What is Lead-Free Assembly

lead-free PCB assembly
Lead-free PCB assembly is a systematic requirement, it requires the electronic components, solder paste, PCB boards to be lead-free. Leaded solder paste not only causes the PCBA to fail RoHS certification, but also causes insufficient solder and fails the board.
The lead-free assembly line can't be used for leaded assembly, because leaded solder flux will contaminate scrapers of the SMT machine and fails afterwards lead-free assembly.
The reflow solder temperatures of lead-free assembly are about 40°C higher than leaded assembly. The peak temperature is about 255°C.

Benefits of Lead-Free PCBs

  • Compared with leaded PCB, lead-free PCBs has higher manufacturing requirements, but you can enjoy these benefits:
  • ● Your products can meet regulatory standards and be shipped worldwide.
  • ● The lead-free assembly has better solderability than leaded assembly.
  • ● Lead-free PCBs are hazardous-free. You and your clients are free from health risks using them and end-products.
