- the electroless palladium plating solution of the present invention is particularly suitable for electroless plating. It can be suitably used for electroless palladium plating that is inserted between nickel plating and electroless gold plating.
- a plating solution having each composition shown in Table 1 was constructed.
- Electroless nickel plating (plating solution: made by Nikko Metal Plating, KG-530)
- the substrate was heat-treated at 165 ° C. for 24 hours. Thereafter, flux was applied to 20 0.48 mm ⁇ pads, and 0.6 ⁇ Sn— 4.
- OAg— 0.5 Cu solder balls were mounted and reflowed at a peak temperature of 250 ° C. in a reflow oven. Bond strength was measured by a heated pull method using a bond tester 4000 made by Daisy.
- a turn test was performed in which the substrate was actually plated with palladium.
- 2MZL of plating is deposited on the substrate as 1MTO.
- the electroless palladium plating solution renews the bath at about 3-5MTO, so if it has a bath stability of 5MTO or more, it can be said that the stability is high. Therefore, the turn test was conducted up to 5MTO, and it was examined whether there was any deterioration in bath decomposition or film properties.
- palladium was replenished every time the palladium concentration during the turn test decreased by about 10%.
- Table 1 shows the evaluation results.
- the electroless palladium plating solution of the present invention is excellent in corrosion resistance and solder jointability. It can also be seen that it is as stable as a plating solution using a conventional sulfur compound as a stabilizer.
