What is FR4 PCB material?
FR4 is a class of printed circuit board base material made from a flame retardant epoxy resin and glass fabric composite. FR stands for flame retardant and meets the requirements of UL94V-0. FR4 has good adhesion to copper foil and has minimal water absorption, making it very suitable for standard applications.

What is the difference between HASL and LF HASL?
LF Hot Air Solder Leveling or LF-HASL is identical to the standard HASL process. However, it does have an obvious difference, i.e., it does no use Tin and Lead Solder. Instead, you will use a Tin and Copper, Tin and Nickel, or Tin, Copper, and Nickel germanium.Jan 19, 2021
