I agree with Evtimov that sticking with the J-Std-033 is preferable to creating your own procedure at a different temp, especially if you need to pass an audit since the auditors will compare your process to the J-Std. My understanding is that oxida

REVISITING MULTILAYER DIMENSIONAL STABILITY AND LAMINATE INTEGRITY It has been said we must learn it all over again and again about every four years. I know Lee Ritchey said that to me about high speed digital circuit design. The same seems true for

Interesting observation Manuel. I will be blamed again for crying wolf but look below a lot more defects will soon see the daylight all related to lead-free. This information was posted at the tin whisker forum by Bob Landman of H&L Instruments.

I'm not entirely sure that is accurate. The only people who want small 'desktop' machines are hobbyists/labs who are unable to accept the costs and time constraints placed upon them by a subcontractor and think they can do better themselves. Standalo

Q1: Are we saying then that IMC can occur at the solder / Cu pad join on the PCB when finished assembled? A1: Yes, but in a broader context I am saying that when someone solders correctly, they form an IMC. Q2: Will the tin diffuse with the Cu over

Patrick, My sardonic wit comes from 11 years of being an embattled process guy who�s basically �seen it all� in electronics manufacturing. I�ve been witness to the �Seagull Managers�, uneducated managers lacking credentials, managers with MBAs but

Jason, What Chrys said! Don't try to run the bottom cooler, tried it in the mid 80's, don't work and don't want it to work. If one side of a fab is maintained cooler than liquidus and the other side into reflow it would have an easy 40C temp diffe

Yes, one should always be concerned about "field failures" because they represent the point at which the product has exceeded its design lifetime with respect to its service conditions. Hybrid microciruit technolgy (HMC) has been around for a long t

First, consider checking the fine SMTnet Archives. Look for threads on "white tin", in addition to "immersion tin". We�ve had a cuppla good ones of late. Merix [http://www.merix.com] gives a good comparison of different solderability preservatives
