A routing miscommunication resulted in a significant problem. The circuit traces for connectors on the left side of a circuit board were supposed to route to the connectors on the right side. Unfortunately the opposite was true. If the circuit board connectors were not rewired and the mating daughter board was plugged, sparks would fly! Do to time considerations re-manufacture was not viable option. There were a few options considered. One option was to manufacture a custom adapter card that included the rewired circuit traces. The conductors could have been mounted to the adapter card and the card could ...

Very large high thermal mass surface mount connectors are difficult to rework. This paper examines the difficulties of reworking a very high thermal mass, high density, 5040 lead count surface mount connector. As we approached this problem it was clear that the rework equipment available did not have ...

Once involved in rework and repair, you quickly realize that all the tools you need to get the job done are just not always available. It occurs to you that unless you're prepared to make the tool yourself, or modify an existing one, you won't have it, plain and simple. Isolating surface pads from ground or other connections is a scenario played out with remarkable frequency in our facility. To make the rework as easy as possible, custom tooling is called for. You basically have three options ...
