...Martyn Gaudion Purpose The purpose of this paper is to discuss nickel gold plating of PCB traces and its adverse effects on signal integrity, and to explore the other key drivers in optimising yields and controlling PCB processes that impinge on signal integrity. Design/methodology/approach...

.... The purpose of this paper is to reduce the operating temperature of an electroless nickel bath by introducing ultrasound to the process. Design/methodology/approach The deposition rate of an electroless nickel solution was determined by two techniques. In the first method, test coupons were plated...
