What is the Manufacturing Process of Bergquist PCB?

The manufacturing process of Bergquist PCB involves several steps, including substrate selection, design and fabrication. Here is a general overview of the manufacturing process:

Substrate Selection:

The first step is to select the appropriate substrate material based on the specific requirements of the application. Bergquist PCB boards are commonly made using high thermal conductivity materials such as ceramic-filled epoxy or aluminum-based substrates.


Once the substrate material is selected, the PCB design process begins. This involves creating a layout that includes the placement of components, signal traces, and power planes. Design software is typically used to create the layout, ensuring proper electrical connectivity and thermal management.


The fabrication process starts with preparing the substrate material. This can involve cutting the material into the desired size and shape for the PCB. Next, a copper foil is laminated onto the substrate, forming the conductor layers. The copper layers are patterned using a process called photolithography, where a photoresist is applied and selectively exposed to UV light to create the desired circuit pattern. The exposed areas are then etched away, leaving behind the circuit traces.

Surface Treatment:

After the circuit patterns are formed, the PCB undergoes surface treatment to enhance solderability and protect against oxidation. This typically involves applying a thin layer of surface finish, such as solder mask or gold plating, to the exposed copper traces.

Testing and Quality Control:

After assembly, the PCB undergoes rigorous testing to ensure its functionality and reliability. This can involve electrical testing, in-circuit testing, and functional testing to verify proper functioning of the circuitry and components. Quality control measures are implemented throughout the manufacturing process to ensure adherence to design specifications and industry standards.
