Hard gold is extremely durable, and is most commonly applied to high-wear areas such as edge connector fingers and keypads.Unlike ENIG, its thickness can vary by controlling the duration of the plating cycle, although the typical minimum values for fingers are 30 μin gold over 100 μin nickel for Class 1 and Class 2, 50 μin gold over 100 μin nickel for Class 3.Hard gold is not generally applied to solderable areas, because of its high cost and its relatively poor solderability. The maximum thickness that IPC considers to be solderable is 17.8 μin, so if this type of gold must be used on surfaces to be soldered, the recommended nominal thickness should be about 5-10 μin.Advantages:Hard, Durable SurfaceNo PbLong Shelf LifeDisadvantages:Very ExpensiveExtra Processing / Labor IntensiveUse of Resist / TapePlating / Bus Bars requiredDemarcationDifficulty with Other Surface FinishesEtching Undercut can Lead to Slivering / FlakingNot Solderable Above 17 μinFinish Does Not Fully Encapsulate Trace Sidewalls, Except in Finger Areas Company ProfileWe know almost all electronic engineers got a problem to found a right manufacturer to make PCB prototypes & small batch order because big factories don't want to make small orders, they always gave high price and very long delivery time, they can't provide fast delivery service. The small factories gave low price, but their quality control and service/English communication are not good, they can't meet customer’s request also.
