RIGID PCB Manufacturer


A rigid PCB is the most conventional form of board in the PCB (Printed Circuit Board) world. They remain enormously popular today and are used in many products consumers use in daily life.

Rigid PCBs
Our PCB Capabilities

Blind Buried Circuit PCB Manufacturer Rigid PCB Capacity:

Rigid PCBs are manufactured as in solid state and inflexible in their structure; therefore, they cannot be flexed or bent. They are composed of many different layers, such as an electrodeposited copper foil, substrate/dielectric material consisting of Epoxy, Resin & Glass Fibre (Prepreg), stacked together using thermal pressure.

Although some PCBs (Printed Circuit Boards) stack constructions can be made as single sided, double-sided & multilayered. rigid PCBs can take any of these depending on the requirements. However, once they have been manufactured, they cannot be delaminated / changed or modified.

Benefits of Rigid PCB

If you are in search of the best option that is cost-effective and in a quick turn around and can be created in prototypes or volume quantities, Blind Buried Circuits are the best option for you. Their manufacturing process and raw materials also tend to be more stable than custom manufacturing shops. For example, if you are seeking a hard-wearing rigid PCB with enhanced circuit thickness from 0.031”(+/-4mils) up to any board thickness.

Rigid PCBs are specifically famous in all industries including (medical, consumer electronics, industrial & communication) and products where it is essential that elements remain fixed, as they can survive with both high levels of stress and thermal heat during their performance and maintain product quality.

At Blind Buried Circuits, we provide our customers with high quality Rigid PCB by understanding their requirements including low glass flow prepreg/dielectric material for RF stackups and all exotic material including 370HR, FR408 HR, Rogers, Nelco, Megtron.

Characteristics, Types, Applications of Rigid PCB

Rigid PCBs (Printed Circuit Boards) are applicable in various day to day devices that we depend on for communication such as:  

  • Mobile Phones
  • GPS Equipment
  • AC/DC Power Convertors
  • Transmission Sensors
  • Computers
  • Tablets
  • Laptops

Additionally, they are applied in essential medical equipment they are generally used in large, non-portable devices such as:

  • CT (Computed Tomography) Scan
  • X-Rays
  • MRI (Magnetic Resonance Imaging) Systems
  • EMG (Electromyography) Machines
  • Heart Monitors

PCBs (Printed Circuit Boards) can survive in high temperatures with the help of exotic material & copper substrates, which means that they are also excellent for the aerospace industry, where they are applied in a range of important equipment.

  • Power Convertors
  • Temperature Sensors
  • Control Tower Instrumentation
  • Aeroplane Cockpit in Instrumentation

Difference Between a Rigid PCB And a Flex PCB:



The rigid PCBs are inflexible in structure.

The flex PCBs can be bent or otherwise shaped because they are flexible.

It is made up of a Rigid core with minimum thickness of 0.031” (+/-4mil), silk screen, and a solder mask.

It is made up of a flexible polymide core of minimum 1 mil, and stiffeners (FR4 and or Stainless Steel) are used for rigidity towards component placement locations, Silkscreen, PSA (Pressure Sensitive Adhesives), and Cover-lay (similar to Solder Mask)

It is used in desktop computers and televisions.

It is used in wearable technology and smartphones.
