ELECTROLYTIC NICKEL / GOLD PLATING PROCESS
Introduces products using advanced surface treatment technology of MK Chem & Tech
TEMPERESIST Series
The TEMPERESIST series is used for high purity gold deposition for semiconductors with a purity of 99.99%. The deposited film exhibits excellent hardness (60-80HV) for wire bonding and excellent stability at high temperatures. In addition, the plating solution can be used for a long time using JPR 2001, a resin for removing metal impurities.
