Since you have home plated the apts and done solder reduction, I would take a look at your soldering profile. We have run into this before when running no-clean and found that reducing the initial ramp rate to the flux activation was a help in the

Hi, We deal with Siemens Siplace parts and we have some cameras on stock. Please let us know if you still need a camera and I will send you a list with some of the ones we have and prices. We may also be interested in a swap with your flip-chip came

Dback, Some questions for you: 1. Are you using the red light configuration for better contrast on the 0402 parts? 2. Is your system fitted with both low and High Magnification cameras? Have you spoken with the guys at YESTech? Their phone support i

Dback, Most likely shouldn't have color inspection on. Using red light colors will look the same so you gain nothing by using this. What exactly are you getting as false calls? Sounds like you have lots of things going on in this type of inspect

Start by checking for hot spots on the cpu board if possible. An IC may have blown or shorted internally. It's probably a driver chip for the print head. But that doesn't explain why the display doesn't work, but if it's overloading the power supp

Just so that we both on the same page: * When you "reflow the chips on the broken board," what do you actually do? How do you do it? What kind of controls do you use? * When someone "did a reflow on the south bridge chipset," what do they do?

Hi bobpan, Just wanted to follow up on my problem. With a bit of reverse engineering, I was able to troubleshhot my board to a faulty trace between the EEPROM and DSP chip. Since it was an 'inner layer' trace I had no choice but to 'green wire' i

We've placed some crazy parts with Mydata but always used the mechanical centering jaws as the vision algorithm is lacking for pattern recognition. Could easily do a poker chip (or other circular things) in the X&Y but maybe the text wouldn't be str
