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) Stressing of Boards

Because the PCB boards have not been exposed to high temperatures, no stressing of the plated-through holes will occur. So the low-temperature processes is that no delamination of the laminate will take place.

(5) 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.

(6) Contamination of Board Surface

Since there is no flux residue on the board surface as there is with solder-coated and hot-air leveled boards, surface contamination is considerably lower. Measurements indicate a 4.5 μg NaCl/sq.cm (29 μg NaCl/sq.in.) contamination of solder coated and hot-air leveled boards and just 1.5 μg NaCl/sq.cm (9.6 μg NaCl/sq.in.) contamination of nickel/gold boards.

(7) Fiducials

Fiducials, the optical targets, achieve a better definition because of the thin nickel/gold layer.

(8) Shelf Life

The shelf life is reported to be a minimum of one year when vacuum-packed.

(9) Keyboard Contacts

It is expedient to execute on-board contacts for keyboards with the same nickel/gold coating as on the SMT pads so that a carbon printing can be avoided. The carbon contacts often show a resistance of 100 to 200 ohms, and also a fairly high degree of instability.
