Igmar, If these parts are epoxied in place, and subsequently wave soldered, I would bet you a cup of coffee that they are cracking due to the thermal shock of the wave. Typically there is a valley or dip in the temperature after the pre-heat in the w

Hi, I need support on the method or applicable standard to measure the shear force strength on chip capacitors and resistors. I know the soldered joints strength is related to land desing, solder volume, pcb and component solderability, component

Assuming that you do not have a solderability problem with the board or part it sounds like you are not pumping the solder up high enough to contact the board plus push into the board by about 1.8mm. Are you using a chip wave in front of the normal

I'm new in SMT world, and I've got my 1st challenge: I'm having de-wetting issues with a specific IC 160 pins MQFP (six location, failure is random), where one pin has de-wetting (solder reflow OK, and there is evidence of having contact the past and

We wouldn't know a Gemini from a bread box, nor we are real clear on what you seek. So, we'll just rattle on for a while. Here's how we monitor the quality of our dispensing process: * We dispense the same nonfunctional pattern of dots on every boa

Well, I have now traced the ready button all the way into the DPRAM board, and all looks good going into a big flat pack chip, valid TTL logic levels when I press the button. But, the machine will not go ready. I have no errors in the system error

CONFUSED???? The the "BIG-chip-in-the-middle" on my image is IC732. IC304 is the 52pin QFP to the right of the "BIG-chip-in-the-middle".If it worked when the "Thingy" was there and does not work when the "thingy" is not there good indications are you
