PCB News - How to reduce circuit board deformation in PCBA design

Printed circuit board deformation is often encountered in the production process of electronic products. This situation will not only lead to the decline of electronic products, but also reduce their service life, reduce user experience, and bring no small trouble to enterprises. Therefore, reducing circuit board deformation is very important for enterprises. So, how to reduce circuit board deformation in PCBA design? What are the precautions?

How to reduce circuit board deformation in PCBA design

1. Enhance the rigidity of structural materials

In the production process for instance, what use originally is plastic product, can change metal casing, can enhance its to resist the impact ability of external force so. If you do not want to replace the shell material, you can consider increasing the rib to change the stress surface, so as to change its compressive strain capacity. Some PCBA designers use coverings to increase their strength, but the coverings must be rigid to be effective.

2. Through the structural design to withstand the circuit board, to prevent its deformation

Using the front and back of the chassis, a pillar is grown to support the circuit board, thus reducing the impact and impact force of electronic products falling from high places, and avoiding the deformation of the circuit board as much as possible.

3. Buffer material to reduce the impact of the product

As is known to all, when an electronic product falls from a high place, it will be subjected to a great impact force, which will cause the product to be damaged or torn apart. The solution to this problem is to choose a good cushioning material to reduce the impact force. However, PCBA designers point out that this method is not suitable for all electronic products, it is only suitable for the board has a fixed screw on one end of the board, which provides cushioning, other difficult to do.

Factors to be considered in PCBA design and production process

1) Product functions

Such as covering basic requirements, product upgrade function, additional product can perform class functions, with easy to manufacture, easy to manage components, etc.

2) Return on investment

Now, there are many manufacturers engaged in the design and production of PCBA, and different manufacturers are different in product quality, cost performance and cost. As PCBA designers, we must strive to improve product quality, reduce product cost, and provide enterprises with low investment and high return choice. Therefore, in the design process of PCBA, we should consider all aspects, so as to ensure the final cost and return on investment.

3) Partners

PCBA design can not be completed by only one person, must be a team to complete. Therefore, if you want to design a good circuit board, there must be a strong team support.
