Paul Maybe you customer could consider the appropriateness of one of the following IPC TM-650 procedures: 2.6.14A, Resistance to Electrochemical Migration, Polymer Solder Mask 2.6.14C, Resistance to Electrochemical Migration, Solder Mask 2.6.14.1, Electrochemical Migration Resistance Test Dave Fish ----- Original Message ----- From: "tech" <[log in to unmask]> To: <[log in to unmask]> Sent: Thursday, September 13, 2001 5:45 AM Subject: [TN] Electro Migration Testing > We're being asked to perform electro migration testing on an ongoing > basis on pcbs we produce. The test required is defined as follows: > A drop of water (.5 Megohms/cm.) is dropped between 2 traces spaced .010 > apart and a current of 3V DC is applied. Current leakage of no more than > 30 micro amps / thou of seperation /minute must be met ??? > Is this a "standard" test and if so is a procedure defined anywhere ( > IPC , MIL. etc) ?
