Custom Flex Circuit Abrader

We had an unusual request for blasting the back of flex circuits to improve the laser solderability of the parts. The backing was too reflective and meant that the laser welds were not always consistent. A custom machine was built to create a uniform area over the back of the area soldered that would not reflect the laser and improve the efficiency of the weld.

The simple to use, machine has tooling to process 10 flexes on each cycle. A simple PLC controller takes care of the machine operation to control the pneumatic arm and the interlocks for the door and blast control.
