PCB supplier china：Lead Free Finishes
PCB supplier china provide PCBs (PCB manufacturing and assembly) with various lead-free finishes:
Solder Finish (lead free HASL)
Electroless Nickel Immersion Gold (ENIG)
Electrolytic Nickel/Gold - Ni/Au (Hard/Soft Gold)
Immersion Silver, Immersion Tin (White Tin)
Organic Solderability Preservatives (OSP)

All of our lead-free PCBs are built from UL approved laminates which withstand the high temperature and long duration assembly cycle (in excess of 260 degrees C). These laminates are suitable for lead free assembly processes that require the laminate base material to withstand temperatures in excess of 260 degrees C or 500 degrees F for extended periods of time. High temperature laminates ensure the higher temperature cycling requirements for some PCB assembly applications.
