Punch Profiling

There are a number of ways to reduce the price and manufacturing lead time for large volume PCB applications and this is always Momentum's objective.

One process that has historically created a bottleneck in PCB production with circular or complex outline circuits is the relatively slow routing stage.

Often a combination of scoring and routing can be a very effective way of reducing the process time on the routing machine (and therefore reduce cost), but oval, circular and convoluted profiles cannot utilise this approach.

In such circumstances, Momentum Circuits are able to offer a choice of either a punched profile or even a method called 'push back punching' that completely removes the circuit from the panel and then presses it back into the panel using a firm friction fit.

The beauty of this method of producing is that is completely negates the need for any secondary finishing as there are no connection 'pips'.

Punching does attract a large initial one off tooling charge compared to conventional manufacture, but conversely the cost of each circuit board and panel manufactured will be proportionaly cheaper based on the reduction in process time required at the 'mechanical stage'.

For large volume requirements, the circuit board cost reduction can very quickly justify the tooling charge.
