Hi Folk, every now and then, i would encounter Functional Failure due to BGA ICs. The Testing Tech always conclude that the contact of the BGA to the PCB Pad is poor. The 2D/3D X-ray machine can't detect any of the poor contact on the BGA..... We

I've used DBA in the past. It's not a bad MRP software for the price. Though, your mileage may vary. We were using an older version of it at my last company, and there was no desire to upgrade. From a manufacturing standpoint (bill of material co

wow.....lets try some more things....... first....i think quad align error 0 has something to do with the theta number not being at 0,6000,12000,18000. I am not for sure about that but check it out by doing a function 3 on your pickups. second.....

Chris, Two points of perspective are: 1 Solderability: The shelf life of components has elapsed when they are no longer solderable. There's tons of variables that affect this, but keys are: * Intermetalics grow as a function of temperature. * Th
