PCB Blog - How to reduce board deformation in PCBA design

PCB board deformation is often encountered in the production process of electronic products. This situation will not only reduce the function of electronic products, but also reduce their service life, reduce user experience, and bring a lot of trouble to enterprises. Therefore, reducing circuit board deformation is very important for enterprises. So, how to reduce board deformation in PCBA design? What are the precautions?

1. How to reduce board deformation in PCBA design

1) Strengthen the rigidity of structural materials

For example, in the production process, plastic products were originally used, which can be changed to metal casings, which can enhance their impact resistance against external forces. If you don't want to change the material of the casing, you can consider adding ribs to change the force surface, thereby changing its compressive strain capacity. There are also some PCBA designers who will use cover to enhance its strength, but this cover must be a rigid material to be effective.

2) How to reduce board deformation in PCBA design, and what factors need to be considered in the production process

1) Withstand the circuit board through structural design to prevent its deformation

Using the front and rear casings, grow a column and then withstand the circuit board, so as to reduce the impact and impact force of electronic products when they fall from a height, and avoid circuit board deformation as much as possible.

3) The buffer material reduces the impact on the product

As we all know, when an electronic product falls from a height, it will be subjected to a large impact force, which will cause the product to be damaged or torn apart. The solution to this problem is to choose a good buffer material to reduce this impact. impact. However, PCBA designers also pointed out that this method is not suitable for all electronic products. It is only suitable for fixing screws at one end of the circuit board, which can play a buffering role, and it is difficult for others to do so.

2. Factors to be considered in the PCBA design and production process

1) Product function

For example, it covers basic requirements, product upgrade functions, additional products that can perform functions, and components that are easy to make and manage.

2) Return on investment

Now, there are many manufacturers engaged in PCBA design and production, and different manufacturers are different in terms of product quality, cost performance and cost. As a PCBA designer, we must strive to improve product quality, reduce product costs, and provide enterprises with options with low investment and high return. Therefore, in the PCBA design process, all aspects should be considered, so as to ensure the final cost and ROI.

3) Partners

PCBA design cannot be done by only one person, it must be done with teamwork. Therefore, if you want to design a good circuit board, you must have strong team support.
