What is 华体会体育·（中国）股份有限公司官网, how to make it, and what are the processes

From design to finished electronIC products, gadgets, SMArt phones, home appliances or appliances, and so on, you can see all the electronic products and equipment. 华体会体育·（中国）股份有限公司官网 board samples are very important. It allows testing of a given design to determine whether it is valid. This allows you to debug and correct any errors. This is also useful before mass production. If there is no 华体会体育·（中国）股份有限公司官网 Prototype, the large-scale production of electronic circuit boards and related products still has risks.

In complex circuit boards, minor errors can be expensive and time-consuming and difficult to correct. Wrong design may make welding of electronIC components very difficult. It is also more difficult to point out the error points on the circuit board. Therefore, it is wise to design 华体会体育·（中国）股份有限公司官网 sample proofing before actual production to avoid any future risks.

Now let's introduce what is a printed circuit board?

Most Electronic devices and products have 华体会体育·（中国）股份有限公司官网 circuit boards. printed circuit board (华体会体育·（中国）股份有限公司官网/PWB) is a board made of non insulating and highly heat-resistant insulating materials (such as glass fiber). These plates are also calLED baseplates. A 华体会体育·（中国）股份有限公司官网 substrate can only have a single layer (single-layer circuit board) or more than one layer (multilayer circuit board). Conductive metals such as copper are used to make conductive paths or traces to promote current. Once 华体会体育·（中国）股份有限公司官网 welding is completed, it is called "printed circuit board". After welding electronic components, the same 华体会体育·（中国）股份有限公司官网 is called printed circuit board sEMI-finished product (华体会体育·（中国）股份有限公司官网A).

华体会体育·（中国）股份有限公司官网 circuit board proofing

When designing a new circuit, it is very important to draw the schematic diagram of the 华体会体育·（中国）股份有限公司官网 circuit board before the 华体会体育·（中国）股份有限公司官网 circuit board proofing. The circuit board schematic will help debug and fix any errors that occur during this process. If the circuit on the circuit board is very SIMple, you can use a very simple sample board. In the case of complex and customized circuit boards, it is necessary to make sample 华体会体育·（中国）股份有限公司官网 boards.

Design software of 华体会体育·（中国）股份有限公司官网 circuit board layout

To start making 华体会体育·（中国）股份有限公司官网 board samples, you need board making information such as Gerber files. 华体会体育·（中国）股份有限公司官网 layout software can be used for this purpose. A circuit board layout software draws the layout of the circuit board and all traces, and points out that the electronic components will be soldered on the circuit board. The 华体会体育·（中国）股份有限公司官网 layout looks like a diagram. The 华体会体育·（中国）股份有限公司官网 layout software allows you to edit the layout until you achieve the desired layout.

How to make 华体会体育·（中国）股份有限公司官网?

Manufacturing 华体会体育·（中国）股份有限公司官网 involves several complex processes.

1: Film plate: In this process, mask or photomask is chemically etched to subtract copper area from 华体会体育·（中国）股份有限公司官网 board substrate. Use CAD 华体会体育·（中国）股份有限公司官网 software program to create photomask using photo plotter design. Photomasks are also created using a laser printer.

2: Lamination: multilayer 华体会体育·（中国）股份有限公司官网 circuit boards are composed of multilayer thin etched boards or trace layers, and are bonded together through the lamination process.

3: Drilling: Each layer of 华体会体育·（中国）股份有限公司官网 needs the ability to connect one layer to another; This is achieved by drilling a small hole called "VIAS". Drilling is mainly done by using automatic computer driven drilling machines.

4: Soldering pad tin spraying: the soldering points of electronic components are sprayed with tin or chemically deposited on the bonding pad on the 华体会体育·（中国）股份有限公司官网 to facilitate the welding of electronic components. Bare copper is not easy to weld. It requires that the surface be plated with materials convenient for welding. Earlier lead based tin was used for plated surfaces, but with R oHS compliance, newer lead-free materials such as nickel and gold are now used for electroplating.

5: Testing 华体会体育·（中国）股份有限公司官网: Before welding electronic components to 华体会体育·（中国）股份有限公司官网, it is necessary to test them. This test can be performed with a test rack tester or a flying pin tester, which is a circuit board test equipment operated by other computers.

The manufacturing process and process procedures are similar for both 华体会体育·（中国）股份有限公司官网 proofing and batch manufacturing, except that the cost of manufacturing 华体会体育·（中国）股份有限公司官网 samples is different from the pre tooling cost allocated during batch manufacturing.
