Soft board circuit board is currently a widely used electronic component, which has the advantages of good quality and diverse specifications. However, in the manufacturing process of flexible circuit boards, there may still be some adverse situations that lead to a decrease in product quality.
This article will provide a detailed introduction to the defects and causes of soft board circuit boards, and summarize corresponding solutions to help soft board circuit board manufacturing enterprises and consumers better understand the production process and quality management of this important electronic component.
1. Wrong through-hole layout
The through-hole connection on the flexible circuit board is very important. If the through-hole is laid incorrectly, it will have a negative impact on the performance of the flexible circuit board, while increasing investment and production costs. The reason for misplacement of through holes is generally due to improper wiring on the drawing or substrate.
Solution: Through careful review by the designer, through-hole errors can be eliminated. At the same time, professional verification methods should be adopted during production to ensure that the position and specifications of the through holes meet the requirements.
2. Poor laying of wires
The laying of wires on the flexible circuit board is a very important part. If the layout is poor, it can lead to problems such as unsmooth lines and slow transmission speeds.
Solution: The quality of wire laying is mainly related to materials and production equipment. To adopt the correct production process and equipment, while using good materials and tools, ensure that the displayed specifications are correct and universal.
3. Poor SMT accuracy
Poor SMT accuracy may have an impact on the use of flexible circuit boards, such as complete electrical appliances, poor contact, and other consequences.
Solution: In SMT engineering, appropriate installation equipment should be used. At the same time, strict calibration should be carried out for various types of surface mount equipment to ensure that the accuracy meets the requirements.
4. Adhesive gets damp
There are many types of adhesives in flexible circuit boards, but if the adhesive gets damp, it can damage the insulation performance of the circuit board and cause other adverse conditions.
Solution: In order to prevent the glue from getting damp, production staff should store the glue in a dry environment and strictly control the humidity.
Overall, the manufacturing of flexible circuit boards requires multiple and complex steps. Only by adopting the correct production plan and control technology can we manufacture high-quality soft board circuit boards. Of course, if there is a problem with the circuit board, we should not hesitate to take corresponding measures to quickly solve the problem and ensure customer satisfaction.
