Hello, readers welcome to new post. In this post, we will discuss Construction of Rigid PCB. PCB board is very significant board in the electronic industry and is used in every part of engineering projects and circuits. Different types of PCB boards are in industry and electronics based on their uses structure and different features. Common types are single-layer, double-layer, multiple-layer, and Rigid PCB.
Rigid PCB can be created in different structures like single layer double layer multiple layers on the requirements of users and applications. It is used in such circuits that after creation not need any changes due to the rigid behavior of the board. There are different PCB manufacturers that offer PCB-based services but one the best in all PCB-based services are PCBWAY. PCBWAY is a high-level PCB supplier and producers offer PCB fabrication and prototyping services having the latest equipment and professional engineers. Their fully assured PCB fabrication features with the design of the board for production permit them to sustain the high user retention rate. You can also get advanced PCBs like flex PCB, and rigid-flex PCB from PCBWAY at good rates with high-quality features
The main purpose of PCBWAY is to provide customers with high-quality, less expensive, and fast delivery. In terms of cheaper electronic projects, it is the first PCB supplier to provide PCB prototyping service at the price of $5/10pcs. If you use the coupons after a new registration, the price will be reduced to zero dollars They provide a template for ten dollars and also have a similar price for different colors of solder mask. The delivery time of the product is usually two to three days.PCBWAY’s main features are fostering relationships with the open-source community, and it also sponsored the 2017 Open-Source Hardware Summit.
As part of sharing your ideas with the PCBWAY community, you can very easily communicate and send your ideas to other members, and you also have the option to vote for the most famous PCB design.
If other community members like your design the most, you will get a ten percent commission. To get other PCB-based services must visit the PCBWAY for your rigid PCB projects they are offering rigid pcb at good prices and high-quality boards. So let’s get started
What is a Rigid PCB Board
- The Rigid PCB is part of the PCB family and used in different types of projects. There is solid substrate used in the construction of this board to avoid the different damages and corrosion facts.
- Its common application in the circuit board of a computer called motherboard is created with use of this board.
- A computer motherboard is created through the use of a multi-layer rigid PCB that helps to transmit the power from the main supply ot other parts of the computer like RAM, CPU, etc
- A rigid PCB board is mostly preferred for conditions where normal PCBs can not sustain and damage easily due to environmental conditions.
- These boards come in different layers from single to multiple eight to ten layers can be created of this board.
- If we compare it to the flexible board will find a clear difference in them. flexible PCB has flexible nature than rigid pcB
Rigid PCB Characteristics
- There are different characteristics of these PCB boards are discussed here
- Rigid PCB board part of PCB family that is not structured like the flexible PCB board since there is shape change in the rigid is not possible or can damage since it consists of FR4 material enhances its stiffness
- There are copper traces and different tracks are created on this board for the connection of different comments on the board to make the circuits. to enhance the rigid and strength of the board there is the rigid substrate used in the board
- Its main example where the rigid board is sued are motherboard of a computer having a rigid substrate
- After the creation of this board not possible to change its dimensions and folded nature
- Its prices are low than the flexible board it is a normal board that is mostly used in different electronic projects
Construction of Rigid PCB
- The construction process of rigid PCB is discussed here. It has some parts that are listed here
- Substrate Layer
- Copper Layer
- Solder Mask Layer
- Silk Screen
Substrate Layer
- The substrate material also named as base material is created with fiberglass
- FR4 is mostly used as substrate material and a commonly used category of fiberglass which enhances the rigid and stiff nature of the board
- With FR4 other base materials like epoxies and phenolics are used but are less effective than the FR4.. But has less cost and a different lousy smell
- Phenolics have fewer decomposition temperatures in results damage to the board if solder is working on the board for a larger time interval
Copper Layer
- At the substrate layers, the copper layer is positioned at the board through use of a certain quantity of heat and adhesive material
- Currently, boards has copper on both sides but some less expensive boards have single-sided copper layers
- Every board has its different value of thickness and is measured in ounces per square foot
Solder Masks
- After the application of copper layers, a solder mask is applied. It helps to protect the copper layers from any environmental conditions damage and corrosion
Silk Screen
- Silkscreen is applied on the solder mask. it helps to make symbolic representations of different components to get a good understanding of the board for making a circuit
- There are different colors of silkscreen like grey red black and yellow but white color is mostly used
Differences Between Rigid PCB And Flexible PCB
- The main differences between rigid and flexible PCBs are explained here
- In different electronic projects, a normal rigid PCB board is used. With the advancement in technology, different projects demand different features and some are not required in certain projects rigid pcb is not used due to its non-twisted nature
- So professionals think about the flexible PCB for such projects where a rigid board is not used.
- The construction of flexible and rigid boards are the same but with some differences like cost softness and flexible nature
- There is a need of extra requirements for a flexible board when it is used in projects. With that certain features are needed to handle the cracking issues in case of board bend
- Flexible pcb is more expensive than the rigid board. But in the case of projects, overall prices may be larger for rigid board but in individual board flexible board is expensive
- Some less expensive devices are created with the use of rigid boards like toys, solid states, keyboards, and some electronic projects.
- For high-performance projects, flexible board is preferred since they not need connectors or tiny structures than the rigi board and will be applied in phones, etc
- To ensure the product’s strength and flexible nature rigid and flexible boards can be used together
- Some flexible boards come with similar structures but not like the rigid circuits
- For applications where bending of board is needed flexible boards are used
Uses of Rigid and Flexible Boards
- Flexible products are more costly than rigid boards. it is that based on projects when flexible pcb used is less expensive than the rigid board.
- Different electronic modules like laptops computers keyboards Tv use rigid boards While flexible boards are used in high-performance structures like GPS, tablets phones cameras
- Due to easy installation LED lights use flexible boards
Applications of Rigid PCB
- Rigid boards can be used in heavy-weight and fewer-weight projects. To get the fines connection and variable resistance multilayer rigid board was used For handling the high volts and high-frequency duty board used
- Rigid PCB used in heavy machines like EMG, tomography, and MRI in medical devices
- In avaitions hgih temperatrues applcations wokrs. Where rigid boards are created through the use of copper and aluminum substrates to handle high-temperature applications. Alos used in APU, airplan cockpit, power convertrers.
- It is also used in automobile applications so here heavy cooper boards are used. to avoid the effect of heat engine, the high-temperature guard is used
- It is also used in AC to DC converter ECU sensors as well
Advantages of Rigid PCB
- It is a low-cost board
- Its working liger higher as compare to flexible board.
- It has high density and is used in mobile phones and computers.
That is all about the Construction of Rigid PCB all details have been explained. Alos must visit the PCBWAY for high-quality boards.Read our More Engineering Blogs
