PCB Technical - PCB quality control method and wiring regulations

First, the method of quality control of printed circuit boards

Under the trend of my country's electronic product consumption system gradually becoming thinner and more practical, flexible circuit board products, relying on good product strength and better structural design, have become indispensable in the current electronic product design Basic accessories, and to ensure that the application of this flexible circuit board brings better results, you need to make the correct choice in the following ways.

What are the methods of PCB circuit board quality control

1. Pay attention to the economy and cost value of the route;

In our country’s current circuit design, there are many ways to connect internal circuits. Good-quality PCB circuit boards believe that when choosing a flexible circuit, it is necessary to analyze the actual input and output ratio of the circuit in this scenario. When the circuit is more complex and the related processing signal and electrical systems are more diverse, choosing a flexible circuit board can better simplify the appearance of the equipment, and through this process to improve the stability of the PCB circuit board production line, only so In order to ensure that the flexible circuit board selected by the PCB circuit board can present a better assembly effect;

2. Consider the reliable flexibility of the circuit board;

In the circuit construction of different products, the flexibility requirements of related circuits are not the same. In the sales of quality-assured PCB circuit boards in my country, there are countless products with characteristics and large differences in flexibility. Consumers want To ensure a better choice, PCB circuit boards believe that it is necessary to be based on economy and practicability to ensure that the selected circuit boards are better, so that fpc can demonstrate its unique flexible circuit characteristics in actual use ;

All in all, if a PCB circuit board wants to ensure that the selected circuit board product has better circuit design capabilities, it needs to determine which environment it can be used in according to the application situation of the product and the basic advantages of the product, and the price of this product Lower and the actual profit is more reliable, can analyze the follow-up profit that this kind of product produced by the PCB circuit board can bring, and only on this basis can the reliability and authenticity of the selection be ensured.

Second, the regulations of the PCB circuit board factory when wiring

The fpc board produced by the PCB circuit board factory is a very commonly used circuit board. Many electronic product manufacturers will purchase and use from this manufacturer, because the high quality and good after-sales service PCB circuit board factory controls the quality of the fpc board Very good, to ensure that quality problems will not easily occur after customers purchase and use. So what regulations does the PCB circuit board factory have when wiring to make the quality of the fpc board so good?

What are the regulations of PCB circuit board factory when wiring?

1. Cut off the extra

The fpc board is an electronic device with high precision requirements. In order to ensure that the quality of each fpc board is reliable, the PCB circuit board factory does not allow redundant wiring when wiring on the board. In addition, wiring The starting end of the cable should be in the specified place with a distance of more than half a centimeter, and the same distance should be vacated to the two sides of the board. If there is any remaining cable after the routing is completed, it must be cut off.

2, protect yourself

Since the wire used on the fpc board is a flexible material, although it can be bent to the required angle, in order to ensure that the circuit is not damaged, the PCB circuit board factory also stipulates that it must be protected when it is routed., Including doing the pad treatment on the side of the board and wrapping it with protective tape, in addition, the copper skin laid on the board should be kept at a certain distance from the circuit.

3, do not perforate the bend

Now single-layer single-sided fpc boards are used very rarely, so the PCB circuit board factory will perforate the circuit when producing double-sided and multi-layer fpc boards. However, in order to reduce the damage to the circuit caused by stress, the PCB circuit board The factory stipulates that the line should not be perforated where there is an angled bend, and the back of the line should be flat.

The above points are some of the regulations made by the PCB circuit board factory when wiring. It is precisely because of the existence of these regulations that a practical PCB circuit board factory can better control the quality of the fpc board and ensure that every fpc board supplied to customers Can get the due quality standards, so in these years, the PCB circuit board factory will win many praises in the industry.
