Use the photo sensor to stop boards instead of the hard-stop. There is also an ultrasonic sensor upgrade. A little more robust than optical. Y Snugger Tooling upgrade is kind of pricey and they like to do that in the plant. But, I've known that upgr

TMC, Are you interested in this approach because you only have a flat belt conveyor and want to keep the components from being moved by the belt on the second pass? If so, you might try adding some stiffeners to the board edges to stand the board o

Thanks for the reply. We have carefully inspected the part and solder joint after depaneling and all looks good. What is weird is if you remove the part from the board and check continuity with a meter you have a dead short. If you put on a new part

The kester better known as KY'd Sn/Cu has more copper intermetallic growth over time, dissolves copper from the board faster so repairing and touchup can damage board. Bridges more than SN100c. Does not thermal cycle well. Has shrink cracks that can

Just to add to what dave said, the only limitation to how frequently you clean is the cost of the cleaning medium. You can wipe every board if you want to, but you'll go through material accordingly. If you're printing 16mil pitch or smaller, cleani

We have a board calling out for 50 micro-inches of nickel over 30 micro-inches of gold. This is a solid gold board on Rogers material. ENIG cannot be deposited that thick right? Electroplated gold (we thought) was usually 35-50 micro-inches and was

I have to hold parts down in my wash baskets. I heard there is a rubber mat with cut outs similar to the screen mesh that the wash basket has. This mat goes over the boards and keeps them from moving through the wash cycle. Has anyone seen this produ

Hi Grant, I can't speak for reliability, I don't know how your boards are going to be used or what alloys you are using. As for RoHS compliancy as far as I understand the cut off if July 1. So any boards sold before that in the EU are OK. Best regard
