What is a Rigid PCB?

A rigid PCB is a non-flexible, durable printed circuit board. It is composed of a solid substrate that maintains its form after manufacturing, commonly made from FR4, a flame-retardant fiberglass material known for its hardness, dielectric strength, and thermal properties. The choice of material depends on specific applications, with some requiring low thermal expansion or different dielectric constants.
Rigid PCBs have three main layers: the insulating substrate (usually FR4), the copper layer (which forms the conductive pathways), and the photoresist layer (a protective covering). These boards are categorized by layers, with single-sided, double-sided, and multi-layer configurations. The more layers a rigid PCB has, the more complex and functional it becomes.
Benefits of Rigid PCBs
Rigid PCBs offer several advantages over flexible counterparts, particularly in devices requiring mechanical strength and durability.
Higher Functionality:
Rigid PCBs support multi-layer designs and high connection density, allowing greater functionality.
Manufacturing Efficiency:
The rigid PCB manufacturing process is highly developed, efficient, and automated.
High Reliability:
Their structural integrity ensures deformation resistance, making them highly reliable for various applications.
Applications of Rigid PCBs
Rigid PCBs are widely used across industries, including:
- Computer Motherboards
- Storage Devices
- Communication Equipment (Satellite, Radio, Antennas)
- Mobile Phones
- Medical Equipment
- Vehicle Infotainment Systems
- Industrial Control Systems and Instrumentation
How are Rigid PCBs Fabricated?
Schematic Design and PCB Layout:
Using CAD software, the board’s design is created, with components and connections carefully mapped out.
Lamination:
Copper layers are laminated to the substrate under heat and pressure, solidifying the board.
Photoresist Application:
A photoresist is applied to protect the copper during etching.
Etching:
The unwanted copper is removed through chemical processes, leaving only the desired circuit pathways.
Drilling:
Holes and vias are drilled using precise, computer-controlled machinery.
Solder Masking:
A protective solder mask is applied to isolate the conductive areas.
Surface Finish:
Copper is treated with finishes such as HASL or ENIG to prevent oxidation and ensure solderability.
Silkscreen:
Important information, such as component identifiers and company logos, is printed onto the board.
