Flexible PCB is also called flexible circuit board. It is favored for its light weight, thin thickness, and free bending and folding. However, the quality inspection of domestic FPCs also mainly relies on manual visual inspection, which has high cost and low efficiency. With the rapid development of the electronics industry, circuit board design is becoming more and more accurate and denser. Traditional manual inspection methods have been unable to meet production needs, and FPC defect automatic inspection has become an inevitable trend in industrial development. 

Flexible PCB is a technology developed in the United States for the development of space rocket technology in the 1970s. It is a highly reliable, highly flexible printed circuit based on polyester film or polyimide. By embedding a circuit design on a thin and light plastic sheet that can be bent, a large number of precision components are stacked in a narrow and limited space to form a flexible flexible circuit. This circuit can be bent freely, lightly folded, small in size, good in heat dissipation, easy to install, and breaks through the traditional interconnection technology. In the structure of a flexible circuit, the materials that are composed are an insulating film, a conductor, and an adhesive.

Prenatal treatment

In the production process, in order to prevent too many open and short circuits and cause low yield or reduce rough process problems such as drilling, calendering, cutting and other FPC board scrapping and feeding problems, and evaluate how to choose materials to achieve customer use For the best results of flexible circuit boards, prenatal pretreatment appears particularly important.

There are three aspects of prenatal pretreatment that need to be handled, and these three aspects are all done by engineers. The first is the FPC board engineering evaluation, which mainly evaluates whether the customer's FPC board can be produced and whether the company's production capacity can meet the customer's board-making requirements and unit costs. If the project assessment is passed, it is necessary to immediately prepare materials to meet various production links. In the end, the engineer processed the engineering files such as the customer's CAD structure drawing and gerber circuit data to suit the production environment and production specifications of the production equipment, and then released the production drawings and MI data to the production department and document control. , Purchasing and other departments, into the regular production process.

Characteristic

1. Short: short assembly time

All lines are configured, eliminating the need to connect redundant cables.

2. Small: smaller than PCB

Can effectively reduce the volume of the product. Increase the convenience of carrying

3. Light: lighter than PCB

Can reduce the weight of the final product

4. Thin: thinner than PCB

It can improve the softness. Strengthen the assembly of the third space in the limited space
