All I ever look at re: thermal stuff is lead finish, max. proc. temp. and dwells anyway. If what you're shootin' at is profiling info., you're right, they don't know jack about my paste.

We wouldn't get our underware in a knot about poor wetting on a lead that is not connected to the board. IPC standards seen to say that the inspector should use common sense in interpreting standards requirements. Then again, it's not all that common

But why not find the cause so later when that lead is used you know how to fix it. Working hard at not working is what's wrong with the world today.

Hi Debra.Baking must be above the evaporation temp of water.This leads to an oxidation problem on the components and affects solderability.Please follow the link and check out Totech on that page.http://www.shanelo.co.za/products.htm

I assume you mean the balls of the BGA, not pads (laugh it up guys - I said balls). If so, you may have a no-lead BGA or a high temp BGA.

Look at this article http://circuitsassembly.com/blog/?p=191 The EU commission totally lost contact with the real world.

yes I have seen that same problem several years ago we didn't change anything the problem went away when we used a differant date code from the same vendor I just figured it was comtaminated leads
