Overview of Lead-Free PCB

  • Are you looking for lead-free PCB manufacturing and assembly made in PCBONLINE? Lead-free PCB means the circuit board contains no lead and is environmentally friendly, and it can be shipped to Europe and around the globe. It has great thermal properties and is more durable than the traditional PCB.
  • From PCB manufacturing, assembly, components, to final product assembly, the whole production can be lead-free if you order from PCBONLINE.

Lead-Free PCB Materials and Process

High-frequency boards have very many requirements for the materials:

  • Selection of lead-free base materials
  • Choosing the correct base material for lead-free PCB is critical as the solder joint of HASL lead-free is 34°C higher than that of with lead. One should consider the heat resistance, CAF resistance, and machinability while choosing.
  • It is most important to use the base material with high thermal decomposition temperature resin as the heat resistance of CCL mainly depends on it, and only by increasing the thermal decomposition temperature of resin in CCL can the thermal reliability of lead-free soldering PCB be guaranteed. In addition, IPC-4101c stipulates that the Td value of lead-free base material should be greater than or equal to 325°C.
  • To choose the correct base materials, PCBONLINE engineers carry out experiments and find that only use only using base material with high Tg and Z-CTE is not enough, which increases the cost and can't improve the heat resistance either. Under the same Tg and Z-CTE conditions, after the T260 test, the delamination time of the base material with Td at 350°C lags behind the base material with Td at 320°C by 10s. Therefore, we suggest that it is better to choose the lead-free base material with Td value greater than 350°C in actual production.
  • Lead-free base material have different machinability with lead base material. The following is the commonly used material comparison table used in PCBONLINE.
