1.5 Advantages of PCB Boards with Electroless Nickel and Immersion Gold

(1) Flat Surface

The most important feature is that the surface of all pads is perfectly flat, corresponding to the underlying copper surface, with all pad and track edges covered by nickel/gold.

(2) Low Defect Rate

An important reason for choosing immersion gold surface protection is a highly reduced failure rate during assembly and soldering compared with solder-coated and hot-air leveled boards. It is especially true of fine line boards with a component pitch of 0.5 mm (20 mils) or less.

(3) Solderability

Solderability is high but the soldering time is a little longer (about 5 seconds.) compared with wave soldering (3seconds.)

(4) Dimensional Stability

Since the boards are not subjected to temperatures above 90° C (194° F) during manufacture, the dimensional stability is high. This is of great importance when screen-printing solder paste on fine-line SMT boards because a better fit between the stencil and the pattern is achieved than in the case of solder coated and hot-air leveled boards.
