Thanks for the advice, Steve. Hard-headed people in high-ranking positions spells trouble.

Hi everyone, this is my first time on this forum. I've only been an innocent bystander. Until now. I wonder if anyone out there knows of any technical publication (accessible over the net) that explains, in detail, the actual physics involved regardi

Whoo-doggies Jason, you said a mouthfull!! (GRIN) Anyways, 'member what I said about me being a pack-rat? Guess what? I found some documentation that I've had for a while that does document the self-alignment forces that goes on when reflowing. I ha

Hi Jason! I can probably find something documented for you, but the easiest way to convince your QA people is just to show them. If you have a board around that has some 1206 locations all in a row, print the board with paste and then plac

All that Phil mentioned plus few tips: 1. Start with the reflow oven. Level the oven and fix it. Then you can go from there to the front end or back end of the line. 2. If you are not sure about all this, hire someone who is. I personally like to d

Greg, The best advice that I can give you is a PBGA will respond just like any other surface mount package. There may be a 5 degree delta between a PBGA 356 and a QFP208 but the two respond very similarly in the convection reflow environment. CBGAs

We've had several instances of parts (1206R, SOT-23) popping off of their location during reflow. Parts placement is OK, paste brick is aligned and compact before oven. But we get random parts off their location just lying somewhere else on the boar

Hi Any, This is from an earlies thread "Solder Ball After Reflow Process". Date: August 16, 2006 01:52 PM Author: Russ Subject: Solder Ball After Reflow Process Oven settings are meaningless here. What does the board see? It is the paste we a
