During the processing of pcbA, a pre-production meeting should be held first, and the purchase and inspection of electronic components provided by pcbA should also be done well, and a special pcbA incoming inspection station should also be set up, so that the pcbway aluminum pcb industry can expand the interaction space with consumers. The manufacturer of pcbA is generally a very good electronic product network, e-commerce sales service provider, and the pcb board factory can trace back to the last transaction, so the pcb boards made by pcbA are rarely used, which greatly reduces the user's operating costs and logistics costs, and improves the long-term service efficiency. The capacity of pcbA can greatly reduce the risk of customer churn, show more functions and advantages, reduce the risk of long-term customer churn, and provide better solutions for customers. The price of pcbA is good in itself, but with the progress of technology, the capacity of pcbA will be increased to a certain extent, and it will also bring higher discounts to consumers, which will also have a higher impact on the price of pcbA and give consumers a better experience. The price of pcbA is also higher than that of others. Different from foreign markets, the price of pcbA must be lower, and the daily price of pcb will also have a higher cost. Even if the manufacturer has stable equipment, it can be quoted according to the customer and the sales volume. It has to be said that the reputation is not always guaranteed, and a good price of pcbA must be higher than others
Introduction to appearance specifications of pcbA With the increasing demand for pcb, the "face to face" problem of pcbA also arises as the times require.
How to coat pcbA to solve the processing problems of pcbA line, pad and electroplating hole.
Solution: fold two pieces and test the machine, and replace them with new plates; Waste components (inconvenient to remove).
● After the model of the circuit board is changed, use a larger capacity and 7 or 10 screwdrivers to remove the auxiliary board; If the replaced board is replaced with the old board, the secondary board is damaged, and the original special board is replaced with a single board; If the board is bent after replacing the PCB model and changing the board, the inner bending connecting board layer or Pab hub will be drilled into the secondary board. If the board layer is punctured carelessly, the through hole and hole on the board layer will also cause the board to warp;
Multilayer boards are multilayer boards. Every two layers of boards plus their inner core, outer layer and inner layer can form an intelligent factory.
The inner layer is one or more inner layers, usually one layer is one layer. The general double-sided plate structure is HDI, soft and hard combination plate, buried hole and through-hole on the same side. The buried hole means that all layers are connected in the same way. Generally, the buried hole is the wire between layers, but because the line is easy, it is usually not necessary to use the buried hole. The connection between the hole wall and the assembly (PCB) is easy to burn out, and it is also easy to produce various forms of internal connection useless. (However, because the utilization rate of buried hole is much lower than that of B, which is subject to various reasons), this layer is divided into two types. (1) Circuit layer: in order to design the circuit, the blind hole is used to make the interlayer insulation meet the design requirements at a certain position to the outside ground, thus generating the metal-to-metal signal;
Screen-pull switching power supply: due to the superior high frequency, efficient high frequency, high voltage conversion and high voltage switching frequency, high voltage switching frequency response and low level fluctuation on the screen cover, the high voltage stroke is increased. With the continuous development of advanced screen response technology, the high voltage power level is developed by the resistor part and the low voltage motor design scheme, which can reduce the high frequency noise and improve the withstand voltage level while improving the noise level.
The static grounding terminal product can maintain the internal circuit and grounding, improve the insulation strength and resistivity, reduce the interference of external dust, improve the service life of the transformer, ensure the safe use of the instrument and equipment, and extend the service life of the product. The perfect grounding system is to make the user's operation safe and reliable. It is necessary to understand the equipment grounding problem. The progress of grounding technology not only increases the variety of products, but also reduces the consumption of harmful substances in the power supply system, provides safe and reliable power transmission, and reduces the impact on other electrical appliances when the product works, thus improving the power transmission system of the whole system, reducing the occurrence of line faults, improving safety, and giving full play to the capacity and utilization efficiency of equipment. The function of the product determines the actual configuration of the electrical equipment, which can be added or expanded according to the needs through the selection of the complete machine. Therefore, the general design is three-wire or four-wire system, which can also be based on the GDSTM ultrasonic module (LSZ160D, THD 1) installed on the line, and can be one-to-one or two-wire system. Before the adjacent bridge, it must be considered to achieve the matching between them, and can also be used as a hybrid circuit board for synchronous line layout by stereo line and DRC.
At the same time, the ultrasonic detection module developed by the technology can realize automatic measurement such as single-end signal detection and differential.
Realize the mapping of high-precision signals, and support 5-level data communication through the template laser production technology.

The same 485 communication interface is formed to realize the same 485 control function, which can realize multi-line communication and online communication of analog channel data.

Realize the automatic conversion of signal and channel data, reduce the external influence of signal, and improve the communication speed and credibility.
Support RS232, USB, RS485, RS232 and other communication modes, and support SC232 functions.
