OTTAWAProcess Photonics today announced a flexible moving probe for laser trimming and testing circuit boards. The company has filed a provisional patent application for the technology, which is headed for customer trials and expected to be available in the fourth quarter.
Most laser production machines are fixture-based, which means designers must custom-build probe cards for each specific circuit layout.

The PPI probing technique is specific to high-speed laser trimming. All probing and trimming is fully programmable; it is said that no fixture is required, regardless of circuit size, orientation or density.
PPI supplies inspection, test and laser-based materials processing systems. It is a subsidiary of Tarquin Group.
