What is Rigid PCB?

A rigid PCB is a circuit board made from solid materials like fiberglass or epoxy resin. This type of board is stiff and does not bend. It includes layers such as conductive copper paths, insulating materials, and a strong base. Rigid PCBs are essential for supporting various electronic components, making them important in many applications.

What are the Components in Rigid Circuit Board?

A rigid PCB board is made up of many layers. These include a substrate, a copper layer, a solder mask, and a silkscreen. These layers are joined by glue and heat.
    • Substrate: Its base material, usually made of fiberglass FR-4 or any other rigid PCB material, holds everything together.
    • Copper Layers: The thin layers of copper are etched to allow the electric impulses to pass through conductive paths.
    • Solder Mask: This is the protective layer that prevents copper traces from oxidation and short circuits.
    • Silkscreen: Identifications of components and reference markings, which are printed.
    • Drilled Holes: For mounting components and connecting different layers of the PCB.

What are the Manufacturing & Assembly Processes of Rigid PCB at FC?

PCB assembly

Step 1: Rigid PCB Design & Layout

Rigid PCB starts with PCB design and layout. This involves creating a schematic diagram of the circuit and then designing the physical layout of the PCB. Design considerations range from PCB size, number of layers, and precise component placement.

Step 2: Rigid PCB Manufacturing

After the Rigid PCB design and layout, the next step is Rigid PCB manufacturing. This contains etching, drilling, plating, solder mask, and silkscreen. The board can then make the necessary connections between the layers.

Etching

Etching means removing excess copper from circuit boards and making the needed electronic parts visible.

Drilling

Rigid PCB drilling is the process of creating holes (or slots) in a bare printed circuit board. It is used to mount components on the PCB board or to connect the board to other boards or devices.

Plating

This is a process in which metal is plated on the entire hole wall. A conductive pattern between the inner and outer layers of a double-sided rigid printed circuit board then enables electrical interconnection.

Solder Mask & Silkscreen

Solder masks are used to protect small electrical lines and facilitate their placement. Screen printing applies to solder mask printing and symbol printing.

Surface Finish

Due to their excellent electrical properties, HASL, ENIG, and OSP are the most common surface finishes for rigid PCB boards.

Milling

The CNC machine routes the PCB circuit contour according to the PCB board contour gerber.

Testing

Open/Short circuit testing is done to ensure the quality of rigid PCBs. Generally, samples and small quantities of rigid PCBs are tested using flying probes. Rigid PCBs for mass production are tested with a test tool.

Step 3: Component Placement

This step will put the components on the board and solder into place. The components are securely attached to the board using surface mount or through-hole soldering techniques.

Step 4: Quality Control & Testing

To ensure the proper functioning of rigid PCBs, they must be tested and inspected after installation. We will use specialized testing equipment to conduct quality control.
