Heavy Copper PCB Manufacturing Process
The manufacturing process of heavy copper PCBs is a critical step in producing these durable and high-current circuit boards. It involves several key stages to ensure the desired quality and performance.
The process starts with designing the PCB layout using specialized software. This includes determining the placement of components, routing traces, and defining the thickness of copper layers. The design must take into account factors such as heat dissipation and current carrying capacity.
Once the design is finalized, it moves on to printing the inner layer circuitry onto a laminate material. Copper foils are bonded to both sides of this substrate through a lamination process. The thickness of these copper layers distinguishes heavy copper PCBs from standard ones.
Next comes the etching stage where excess copper is removed from areas not covered by protective solder mask or silk screen printing. This ensures that only required conductive pathways remain.
After etching, holes are drilled into the board for component mounting and interconnections between layers. These plated-through holes play a crucial role in achieving reliable electrical connections throughout the PCB.
Following drilling, an outer layer pattern is printed onto each side using screen printing techniques or photo imaging processes. This adds another level of protection to prevent oxidation and corrosion.
Testing procedures are conducted to verify functionality and reliability before assembling components onto the finished heavy copper PCBs.
With meticulous attention to detail at every stage, manufacturers can produce heavy copper PCBs capable of handling high currents while maintaining durability under demanding conditions.
