Hi Joe, first of all thanks for your input. I did tried to search for the Mydata brochure and found that they are using Lifescan Vision System (LVS) which i think should be vision analysis. Appreciate if you can explain more in detail how's the mecha

Hi, If your PCB is large, you waste a time. Any picture, you takes, will be with corner distortion. I suggest you to: 1. use AOI (manually or automatically) 2. try simulation of your PCB production before real SMT production process 3. use human FAI

We have the thermal connections on our omniflow, but we prefer to use the mole. I actually prefer the kic profiler over the mole profiler, but you work with what you have sometimes. The benefit of using an external system is you don't have the long t

We have used JBC soldering stations many years without any major problems. Handpiece is lightweight and comfortable to use. Tips are bit expensive but worth of money. Go Nano for 0402 and smaller and HD for massive part soldering. JBC CD-2BB Solderi

I'm looking for evidence to support, or disprove, the use of Nitrogen in the reflow oven. I've heard many arguments on both sides. I have my own personal opinion. But I'm looking for scientific studies or white papers, specifically addressing the ben

We have for a time been collecting data, but unfortunately don't use it. The issue we have is with mainly missing items being found at inspection or un-soldered joints not being spotted. I am wondering if anyone else in the same situation and NOT us

Back in the mists of time there were two papers on the use of Parylene Coating and the improved thermal cycling results in 1990. It was on LCCC then shortly after on BGA. Does anyone know of results of recent trials or have a copy of the BGA papers.

We have been using a circuit board in the assembly of HV Tank used in X-ray generator. This board acts as a sealant to the oil tank opening. The top side area of the board which comes in contact with oil is conformal coated to avoid oil leak. However

What are the typical environmental regulations in the US for reflow exhaust if any? We are using a lead free process although I assume it has more to do with the flux than the alloys used. Do we need to look into something like a Title V permit?

When you need a few board modifications made such as cutting some traces or adding pads/traces and you do not have time for a board spin or have lots of pricey boards with mistakes what resource are you using? Internal or external? What method is bei
