Next Generation Probe Card Based Resistor Trimming Systems

Over forty years ago electronics manufacturers developed the process of using a laser to adjust operating parameters of an electronic component or circuit by reducing the amount of resistor material. Early designs used probe cards for their testing method as they were an excellent solution to high volume production applications.

The Benefits of Dual Laser Microvia Drilling

The drive for smaller but high-functionality handheld devices led to the implementation of laser-drilled microvias over 20 years ago. Laser drilling of vias is now an established process in the PCB industry for many different circuit applications. Two laser types and three main methods are in use: UV laser drilling only; CO2 laser drilling only; and a combination of both the UV and CO2, commonly referred to as the hybrid process. This hybrid process provides the greatest opportunity for process optimization in the widest range of materials.
