Review of Tin-Copper and Tin-Nickel Intermetallic Thickness
Review of Tin-Copper and Tin-Nickel Intermetallic Thickness
What is the desirable intermetallic layer thickness? I have read that 1 - 2.5 micron thickness of tin-copper is desirable and a .4 - .8 micron thickness on tin-nickel is desirable. The Assembly Brothers, Jim Hall and Phil Zarrow, address this.
