The Rise of Rigid PCBs
Due to the development trend of aerospace products, including lightweight, miniaturization, multifunction, and assembly densification, a higher requirement has been founded for printed circuit board (PCB) technology and manufacturing process. Rigid PCBs are a kind of circuit board that is fabricated from different substrate materials and have more advantages than ordinarily PCBs.
Furthermore, electromagnetic signals can run quickly and smoothly in rigid PCBs due to the excellent electrical performance and thermal performance of rigid substrate material so rigid PCBs are widely applied in many industries like instruments, automotive, treatment, military, and aerospace. Based on the further development and optimization of rigid PCBs, the subsequent step for them should be Rigid PCBs, Embedded Rigid Circuits, and HDI Flex PCBs, among which Rigid PCBs attracts the foremost attention and applications.
Rigid PCB Definition
What is Rigid PCB?
A rigid PCB is a Solid, inflexible printed circuit Board. We all know that a PCB is Single Sided PCB, Double Sided PCB, or Multilayer PCB. At the identical time, a printed circuit board is often Rigid, Flexible, or Rigid-Flex (A combination of Rigid and versatile PCB). So, a Rigid board is a Board that we cannot bend or force out of shape. It’s not flexible. A Rigid PCB can be Single Sided, Double Sided, or Multilayer board.
Once a Rigid printed circuit is manufactured it cannot be modified or folded into the other shape. A rigid circuit card is created of the solid substrate with copper tracks and component layouts where Active and Passive Electronic Components (Through-Hole, SMD Components, or Mixed PCB Assembly) are soldered either by automated Through Hole Soldering Technology like Wave Soldering or Automated Surface Mount Technology (SMT) like Reflow Soldering and Hand Soldering can also be done.
Characteristics of Rigid PCB
Here are some characteristics of Rigid PCB:
- Rigid PCB is a quite conventional PCB, which may not be like Flexi PCB because rigid PCB cannot be twisted or folded into any shape because it’s FR4 reinforcement, which is incredibly useful for increasing stiffness.
- Rigid PCB comprises copper trances and paths, which are incorporated on one board to attach the various components. The bottom material of the board is created of a rigid substrate which provides rigidity and strength to the board.
- The computer motherboard is the best example of a rigid PCB with a rigid substrate material.
- Once rigid PCBs are manufactured, they cannot be modified or folded into the other shape.
- Rigid PCB is cheaper than flexible PCB. They’re traditional PCBs and are widely utilized in many electronic products.
- Flexible PCB and rigid PCB have their limitations and advantages in terms of easy use and availability. Both of them are wont to connect multiple electronic components on circuit boards.
How to make a rigid PCB?
Like any other PCB, rigid PCBs are manufactured by following a certain process. Here, we will discuss each phase in the whole manufacturing process of a Rigid printed circuit board.
Rigid PCB Manufacturing Process
These are the fundamental steps utilized in the assembly of rigid PCBs. These PCBs are often constructed with single, double, and multiple layers. For a PCB to satisfy all requirements of the application, it’s important to produce detailed information about the appliance to the PCB manufacturer. This can allow him to style the PCB in step with your needs.
