circuit board factory warm tips, circuit board is circuit board, circuit board name: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printing (copper etching technology) circuit board, etc. The miniaturization and visualization of circuit boards play an important role in the mass production of fixed circuits and the optimization of electrical layout. Circuit boards can be called printed circuit boards or printed circuit boards. It is made of polyimide or polyester film. The highly reliable and excellent flexible printed circuit board has the characteristics of high wiring density, light weight, thin thickness and good flexibility. The circuit board factory warmly reminds that the hard and soft board is a kind of circuit board with FPC characteristics and PCB characteristics, which is composed of flexible circuit board and rigid circuit board through pressing and other processes according to relevant process requirements. What are the classifications of

circuit boards? Circuit board factory answers for you!

circuit boards are divided into three major categories: single-panel, double-panel, and multi-layer circuit boards according to the number of layers.

is single panel first. On the basic PCB, the parts are concentrated on one side and the wires are concentrated on the other side. Because the wires only appear on one side, this PCB is called a single-sided circuit board. Single panels are usually simple to manufacture and low in cost, but the disadvantage is that they cannot be applied to overly complex products.

The double-sided board is an extension of the single-sided board, so when the single-layer wiring cannot meet the needs of electronic products, the double-sided board will be used, both sides are covered with copper and have wiring, and the wiring between the two layers can be connected through vias., To form the required network connection.

Multi-layer board refers to a printed board with three or more conductive pattern layers, an insulating material is laminated between these conductive pattern layers, and the conductive patterns are connected to each other as required. Multi-layer circuit board is the product of electronic information technology to high speed, multi-function, large capacity, small volume, thin weight.

According to the characteristics, the circuit board can be divided into soft board (FPC), hard board (PCB) and soft and hard board (FPCB).

In use, the circuit board should be maintained regularly to ensure that it is in good working condition and reduce the failure rate of the circuit board. In the use of circuit board maintenance is divided into the following several kinds of situation, circuit board factory for you to answer!

1. Semi-maintenance:(1) Clean the dust on the circuit board every quarter, and use the special cleaning fluid for the circuit board. After cleaning the dust on the circuit board, blow dry the circuit board with a hair dryer. ⑵ Observe whether the electronic components in the circuit have traces of high temperature and whether the electrolytic capacitor bulges and leaks. If so, it should be replaced.

2. Annual maintenance:(1) Clean the dust on the circuit board. ⑵ Sampling inspection of the electrolytic capacitor capacity in the circuit board. If it is found that the capacity of the electrolytic capacitor is less than 20% of the nominal capacity, it should be replaced. Generally, the life of electrolytic capacitors will be replaced in about ten years to ensure the working performance of the circuit board. (3) For high-power devices coated with heat-dissipating silicone grease, check whether the heat-dissipating silicone grease is dry. For dry, remove the dry heat dissipation silicone grease and apply new heat dissipation silicone grease to prevent the high-power devices in the circuit board from burning out due to poor heat dissipation.
