IPC-A-610F 10.2.6 Laminate Conditions - Depanelization talks to the acceptability of the depanelization criteria for assembled boards. There is no requirement for moisture sealing with epoxy or other material. Basically, the standard requires that th

We built our own coating system by mounting a Universal Robots UR5 to an edge conveyor between a magazine unloader and magazine loader. The robot has a needle dispenser on the head. We chose a needle dispense process to avoid aerosols and complex ven

Electrochemical migration under conformal coating: That's possible. Very few conformal coatings are water resistant. So, if you have ionic material on your board, standback. Uncured material under several IC: Materials like yours need moisture fro

Reaching out to all conformal coating experts, please help! While setting up conformal coating using the automated atomized spray, we observing issues associated with conformal coating wetting on the following regions: 1) Component edges 2) Metalli

Dave, thanks for the reply. These boards have metal plating covering 99 percent of both primary and secondary surfaces. The only places without the metal plating are the extreme outer edges and about an 1/8 inch surrounding the plated holes. We do

If the operator has zero charge and the board has a 10kv charge, when the operator pulls the shorting strip from the edge connector after the coating has cured, there is a large potential for ESD induced damage.
