PCB board surface treatment

1) Tin spraying is the most common surface treatment process in the PCB printed circuit board industry. It has good solderability and can be used for most electronic products. For other surface treatments, tin-sprayed plate has the advantages of low cost and good solderability; its disadvantage is that the surface is not smooth with immersion gold, especially when a large area of windows is opened, the phenomenon of tin unevenness is more likely to occur.

2) Immersion tin, the difference between immersion tin and spray tin is that its flatness is good, but the disadvantage is that it is easy to oxidize and blacken.

3) Immersion gold, as long as it is "sinking", its flatness is better than that of "spraying". Immersion gold is lead-free. Immersion gold is generally used for gold fingers and key boards. Because of the small resistance of gold, gold must be used for contact, such as the key board lights of mobile phones. Immersion gold is soft gold. For those that are often plugged and unplugged, gold plating is used. Immersion gold is mainly immersion nickel gold.

4) Gold plating, gold plating has been mentioned in immersion gold. When gold plating has a fatal deficiency, its weldability is poor, but its hardness is better than that of immersion gold. This process is generally not used in the design of MID and VR
