This latest problem is a board fabricated but with a long row of plated holes for a connector that should have been connected to the ground. The holes were not connected to each other or ground. It would seem easy to find a ground point and link the connector pins using a wire once the board was populated, but a surface wire was unacceptable. A connection was needed ...

Circuit Technology Center has added the capability to trim and form electronic component packages to customers' exact pre-assembly specifications. Precision form and trim of SMT flat-pack and axial and radial lead through-hole components are supported in both low and high-volume quantities. A robotic hot solder dip component lead tinning process usually follows trim and form to coat the component leads with solder to prevent oxidation or to remove gold plating from the formed leads.
