PCB knowledge: HASL
Hot 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 240. 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 300, 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.
FAQ:What's your minimum track and spacing?
Actually this depends on the copper weight.
For half oz(18um) copper, it's 3mil / 3.5mil for prototypes, 4mil / 4mil for small production and larger at 5mil / 5mil for mass production.
For 1oz (35um) copper, it's 3mil / 4mil for prototypes, 4mil / 4mil for small production and 5mil / 5mil for mass production.
For 2oz (70um) copper, it's 6mil / 7mil for prototypes, 6mil / 8mil for small production and 7mil / 9mil for mass production.
For 3oz (105um) copper, it's 8mil / 9mil for prototypes, 8mil / 10mil for small production and 9mil /11mil for mass production.
For 4oz (140um) copper, it's 12mil / 11mil for prototypes, 12mil / 12mil for small production and 13mil / 13mil for mass production.
