Process

Heavy Copper PCB Manufacturing Process

The complete heavy copper PCB manufacturing process is based on the design package that makes the circuit board in physical form. Following is the process of heavy copper PCB which starts with design and ends with testing:

Step 1: Pre Production Engineering

According to the manufacturing data and requirements provided by the customer, our engineers will compare it with standards and capabilities to make sure compliance and conduct related checks.

Step 2: Photo Plotting

A laser photo-plotter can be used to plot a film for each individual layer. A laser photo-plotter is a tool used to create photo-tools for solder mask and silkscreen.

Step 3: Imaging and Develop or Etch

This process applies the primary images such as pads and traces onto the circuit board. Here is what to do in this step: Apply photo imageable to the copper panels. Furthermore, image the panels using LSI. Etch off the whole exposed copper from the panel. Strip the remaining Dry Film and just leave the remaining copper pattern for the inner layers.

Step 4: Automated Optical Inspection

AOI basically inspects different layers of multilayer PCB before laminating all layers together. The optics compare the PCB design data to the actual image on the panel.

Step 5: Oxide

Oxide is a chemical treatment to inner layers before lamination for multi-layer PCBs. It is an important step to increase the roughness of copper to enhance the laminate bond strength.

Step 6: Lamination

To produce a multilayer PCB, different layers of epoxy-infused fiberglass are laminated together. The presser and heat cause the fiberglass sheet to melt and tightly join the layers together.

Step 7:Drilling

All PCBs need some holes to link copper layers, attaching components and mounting the PCB. We can drill holes using some advanced drilling systems. Furthermore, these have a design for the fast removal of chips in abrasive materials.

Step 8: Electroless Copper Deposition

After drilling, manufacturers deposit a thin coat of copper on the exposed surfaces of the panels chemically. Furthermore, they deposit a copper coat on the hole walls using electroless plating.

Step 9: Dry Film Outer Layer

After copper deposition, you must apply the outer layer images to prepare the panel for electroplate. So we can utilize a laminator machine to coat outer layers with the dry film. The dry film is a photo imageable material.

Step: 10 Plate

The electroplating process involves copper plating onto the conductive pattern. Plus on the hole walls of the PCB as well. The thickness of the plating is around 1 mil. After copper plating, you need to deposit a thin layer of tin plating.

Step 11: Striping and Etching

After completing the plating process on the panel, the dry film remains. Then, removing the uncovered area of copper by tin. So traces and the pads around the holes and copper patterns remain there. At last, remove the remaining tin that is covering holes and traces chemically.

Step 12: Surface Finish

It is the last and final chemical process to manufacture a multilayer printed circuit board. Solder mask covers almost all circuitry. So the surface finish prevents oxidation of the remaining exposed copper area.

What is a heavy copper PCB and its types

A Heavy Copper PCB is a type of printed circuit board that is characterized by having thick copper layers. The term “heavy copper” refers to copper layers that are greater than 3 ounces per square foot (oz/ft2). By contrast, a standard PCB typically has a copper layer thickness of 1 oz/ft2. Heavy Copper PCBs can have copper layer thicknesses of up to 20 oz/ft2, making them ideal for high-current applications.

There are several types of Heavy Copper PCBs, each designed for specific applications. Some of the most common types include:

● Single-sided Heavy Copper PCB: This type of PCB has a single copper layer on one side of the board, with the heavy copper layer typically located on the same side as the components. Single-sided Heavy Copper PCBs are commonly used in power electronics applications and can handle high currents.

● Double-sided Heavy Copper PCB: This type of PCB has copper layers on both sides of the board, with the heavy copper layer typically located on one or both sides. Double-sided Heavy Copper PCBs are used in applications where high current carrying capacity and improved thermal management are required.

● Multilayer Heavy Copper PCB: This type of PCB has multiple layers of copper and insulation material, with the heavy copper layer located on one or more of the inner layers. Multilayer Heavy Copper PCBs are used in high-density applications, where space is limited, and thermal management is critical.

● Hybrid Heavy Copper PCB: This type of PCB combines heavy copper layers with other materials such as ceramic or aluminum to provide improved thermal management and mechanical strength. Hybrid Heavy Copper PCBs are commonly used in aerospace and defense applications.

● Flex Heavy Copper PCB: This type of PCB is a flexible circuit board that combines heavy copper layers with a flexible substrate material such as polyimide. Flex Heavy Copper PCBs are used in applications where space is limited and flexibility is required.
