Learn PCB and Buy PCB --- HASLHot air solder leveling is for short HASL, which is a common type of surface finish used on printed
circuit boards (PCBs). We dipped the PCBs (with exposed copper surfaces) into a bath of molten
solder, then remove the excess solder on PCB surface and in the holes by strong hot air(which we
call it HASL machine) to get a glossy layer of coating.
One is alloy of tin and lead. The temperature of smelting furnace for Tin/Led is about 240ºC.
Another one is pure tin, because lead is harmful to human body, EU has forbidden using tin/lead.
So the popular is pure tin or HASL Lead free. The temperature of smelting furnace for pure tin is
highly at 300ºC, and plus the operating environment, high temperature and high etching are great
harm on PCB itself. Due to its hot air generated, HASL has low planarity. It makes this surface
finish unsuitable for use with fine pitch components. It has hidden danger of board warp or twist
under high thermal stress. To avoid this disadvantages, high Tg material and PP are took into
consideration for some PCB user. But it also has excellent wetting during component soldering
and it can avoid copper corrosion. So it is also mostly used in single sided PCB, Double sided
PCB and some multilayer PCB.
