In the REAL world most people don't have time to send out problem boards and wait for someone else to do their work. In the real world most of these problems on this forum are caused by someone doing something dumb, or a change was made that the pos

Hello all Our Omni 5 has given the 'Cooling module high temp' warning twice during the past month. I suspect that the blower motor is the culprit but have not been able to verify this because the oven has started up normally after acknowledging the

Some use small cleaners but I have always used the stencil washer. Most stencil washers come with a basket of some kind of board holder (or via holder - depending on how technical you want to get). Buying a stencil cleaner is hard to justify just f

Hi, I just saw the new NXT machines at globaltronics in Singapore, and mostly they are faster. However what was interesting is Fuji shows a prototype of the new XPF machine, but it was called XPF-W which handles really large PCB's and uses the sam

This is my first circuit board that I am attempting to build and need a little help. Not exactly sure what is going on but maybe one of you guys could give some input. I am attaching the electrical diagram I am using. Everything thing seems to be wor

I'm just wanting something solid to show my workplace. I am under the belief that it is a flattened coined lead. But like how i've been trained in IPC, I have to be able to prove that it is true... or that IPC says it is false. We have a customer tha

Dear Steven: Often the recommendations for baking prior to assembly are derived from various J-stds. But J's currently concern baking moisture out of components, and fail to address the moisture issues of the PCB. Because of that, there is the IPC D

What is the shift structure of your shop? If your facility has only one 8 or 9 hour shift per day, then a 3-day turnaround is nearly impossible. However, if you are running multiple shifts that keep the shop alive 24 hours per day, then it is absolut

We've had this same problem with the solder wicking to the component terminations. However, in our case, we did not see the pads turning a silver-white color...rather, they exhibited a tarnishing/darkening of the gold. We determined that we had som

Is this a sample board that you ran without components? If so, I'd get it back to your board house, and ask them to explain to you what's happening. We never did get to a satisfactory root cause on our issue (at least, satisfactory to me). It seem
