Got handed an assignment for which I'm not totally qualified. Don't expect this forum to had me all the answers. Some answers are obvious as the device types are fairly self explanatory. As everyone knows, IBM had problems with their ceramic BGA dev

We find that baking PCB assemblies at 90 degrees C in a Blue M forced air oven is safe for most all PCB's that we have encountered over the past 12 years. We remove any external plactic hardware that may be attached to the assembly and also like to

Some people run underfill through their reflow oven set with a normal recipe, but at breakneck speed. We think that might not produce the cure that we'd like to obtain. We'd don't use our reflow oven because we don't want to given-up the time to

Mark, that would be a good report to have a look at can you post it on the site or mail it out to me? Also I've been having an issue with blue peelable solder mask on silver boards where it peels the silver off with it. I've only seen this since my v

I am using masking tape, the 3M high temp blue masking tape. the problem though doesnt seem to be related to the masking tap as i am seeing pin holes and eventual dewets over entire ckt board (its almost as if the board has chickenpox under black lig

I'm new to all this... we have a board with one BGA blue tooth device. one test for the board is an rf test that measure successful packet transmission. we find that we get much lower error rates if we "reflow" the BGA with a heatgun. We do this

We're guessing the ink wasn't fully cured, when they finished the ENIG. If the supplier is correct that it was your 'process that is caused the changes,' then they certainly won't mind you bringing over a couple of unstuffed boards and running them

Brad, Thanks for the info. Now that I have my align data set correctly I'm having this problem. I've greased and realigned until I'm blue in the face. If I do a nozzle change then a function 30, press the nozzle on with my finger and do a functio
