Hey all, we will be starting to coat our PCB's soon. I am looking for info on what type of UV light is needed to inspect the boards. We will be using Humiseal 1B73 Acrylic coating. TIA, JD

I am not familiar with a WOOD light. The TDS for this material says it fluoresces under UV light....

Wood or Black Light is the common way to call that UV ligth used ie. inside "disco" and used for many applications like to activate the fluorescent particels contained by conformal coating material,adhesives, paper money, etc. Any way ask for TL-08

Hopefully the coating does contain a UV tracer. We used a silicone years ago that did not, but UV did make it fluoresce to a degree, you just couldn't ensure 100% coverage. One time we did have a problem with the coating getting on connector pins,

We use a Luxo handheld magnifier that has both UV and white light built in. You can get one from Techni-Tool (p/n 516IN401) or HMC Electronics (p/n 16401).

You can buy bulbs for any T8 T10 fixure. You can buy black light bulbs or white uv bulbs and just pop them in. There should be a bulb supplier in your city that has them.

Hi, I think concept of inspection through AOI is changing. I am struck in confusion.Because some manufacturer say 3D inspection, with 1+4 cameras is ultimate solution. Orbotech also came with 13 cameras at once!Now some say, all these are eyewashing

Manjunath, I prefer orthogonal systems. In my experience they are actually better at detecting coplanarity and HIP defects than multi camera systems. They are obviously limited, in that they can not inspect a component under another component, b

Alan, You're right, mass inspection after assembly won't work. The inspectors will miss 25% (or more) of the defects, and the boards will be reworked before SMT operators can properly define defects and their sources. The company I work for tends to

Hi Clark, Out of curiousity and in the name of learning new stuff, can you share with us how does your team, calculate the cost of inspection? Is inspection an additional chargable item in the quotation sheet? To quote your posting : "Just a side n
