Hi! Try get copies of the following references - they have some good data on immersion tin: Journal of Electronic Materials, Vol. 25, No. 7, 1996 "Interfacial Reactions During Soldering with Lead/Tin Eutectic and Lead Free Tin Rich Solders" Kang,Rai,Purushothaman Journal of Electronic Materials, Vol. 25, No. 7, 1996 "Wave Soldering with a low Melting Point Bi-Sn Alloy: Effects of Sldering Temperatures and Circuit Board Finishes", McCormick, Artaki, Jin,Jackson,Machusak,Kammlott,Finley IEEE Transactions on Components, Packaging,and Manufacturing Technology, Part A, Vol.18, No. 1. March 1995 "Influence of Temperature and Humidity on the Wettability of Immersion Tin Coated Printed Wiring Boards", Ray, Artaki,Vianco Dave Hillman Rockwell Collins [log in to unmask] ______________________________ Reply Separator _________________________________ Subject: immersion/electroless tin plating Author: [log in to unmask] at ccmgw1 Date: 7/30/96 11:02 AM To: IPC; PCBFab From: Lee-CTUA065 Bab-Hui on Tue, Jul 30, 1996 10:27 PM Subject: immersion/electroless tin plating Any body out there has experience in using immersion tin or electroless tin as a final surface finish on PCBs for solderability application? Currently what types of product are available in the market & who are the major chemical suppliers? Appreciate if anyone can provide an answer. Thanks. Regards, B.H.
