Thick copper PCB has the best elongation rate, which is not limited by processing temperature.The melting point is high, which can be used by hot-melt welding methods such as oxygen blowing and low temperature non-brittleness. It is also fireproof and belongs to non-combustible materials.Thick copper PCBs form a strong and non-toxic passivation coating even in extremely corrosive environments
What is HASL?
HASL (High Aspect Ratio Surface Laminar) is a technique used in the production of printed circuit boards (PCBs). It involves depositing a layer of copper onto the surface of the PCB and then etching away the excess copper to create the required circuit pattern.
HASL involves immersing the printed circuit board in a bath of molten solder, then using hot air to level and smooth the surface.
