To perform conformal coating of PCBs in high power electronics applications follow IPC-A-600F and IPC-CC-830B conformal coating standards. This standard enlists several performance criteria. Additionally, this standard is considered as a good referen

The software is crazy expensive for some of this stuff and in many cases you could develop the bits of it you actually use in-house for a fraction of the cost. Unless you are a company who really like this level of process control and you run multip

I have experienced tombstone with one brand of 0603 capacitor. Swapping in another brand (actually two different brands to date) has stopped the tombstone. I have measured the parts (length, width and height). There does not appear to be any apprecia

It is the distance between board and stencil. When your stenciling solder paste you usually want to contact print (which is "0" snapoff). When you are stenciling adhesive you can affect your dot size and quality by using a gap between board and stenc

We have talked about using mircoscopes and laser thingies for measuring paste height on SMTnet previously. [Fine SMTnet Archives might give background.] Some people use a 0603 chip cap as a standard. I'm not sure how stencil height relates. Paste

We are evaluating conversion to ISO 2000. One area we are attempting to get started in is 8.2 Measurements and Monitoring. We will be required to monitor customer satifiaction. I feel the customer in our case is the dealer for our product. He buy

I agree with Wolfgang that a check list, like he proposes, is very useful in evaluating your ability to assemble products. No sense designing a 16 inch board if the throat of your wave is 15 inches. Taking a different tact � what if you define your

Does anyone know of a source for a reasonably priced and simple airflow measuring instrument? A simple mechanical anemometer with a pitot tube would suffice (I think...) in this application since I'm just trying to verify proper operation of the refl
