Introduction to PCB proofing analysis

Circuit board is also known as PCB, that is an important electronic component part,the support plate of electronic components and the electrical connection provider of electronic components.

Circuit board proofing refers to the trial production of printed circuit board before mass production. It is mainly used for electronic engineers to design and complete the circuit board, then conduct small batch trial production to the factory, which aims to make samples for the circuit board. And the production quantity that circuit board makes a sample does not have a specific demarcation line. Normally It is called a circuit board proofing before a product design is not been finally confirmed or tested .

Proofing Focus:

First, about Speed

The PCB market is constantly changing.Time is a very important factor in this industry. Delivery time and quality are the hard power of the factory, and are the most favored by engineers and the factory. Now the circuit board factory generally provides a urgent service, and the normal delivery date of the factory is 2 days. For example, now in the FASTPCBA electronics, all the template default urgent, quality control, engineering, production real-time monitoring of the whole process of proofing progress, and our advantage is advanced production equipment: such as the MYDATA-600 Jet Printer,according to MYDATA-600,there is no need to make a stencil first,it gets the following advantages :automatic production,saving time ,precious products.

Second, about Quality

Engineer in the PCB design has not completed the confirmation and the test before the trial production, the quality must not neglect.From raw materials, drawing, and production links, testing, quality control, and so on. Every link needs to be strictly checked.For example, now generally speaking, the general double panel, plate material fr-4, aluminum substrate, CEM-1, etc., the thickness of the plate from 0.4mm to 3.0m, copper thickness from 0.5oz to 3.0oz. Differences of these factors will differ the finally price much .At present, a better PCB board material used by manufactures is a kind of environment friendly one .

Third, about price

With the development of the industry, the price of PCB proofing make,small and medium-sized batch production is at a really low level.At present, many proofing companies, such as jetpack, they have already canceled all proofing service, for film fees ,it has vanished too . Completing challenging tasks with challenging prices will be the coming trend of circuit board proofing price in the next step.

Circuit board proofing quality measurement standards:

1. Copper is not easy to fall off under high temperature;

2. The line thickness, line spacing and line width of the line all meet the design requirements to prevent the line from heating, short circuit and circuit break;

3.PCB circuit board has no additional electromagnetic radiation;

4.High temperature, high humidity and other special environment should be taken into account in the process of PCB circuit board proofing;

5.Copper surface is not easy to be oxidized;Oxidized circuit board service life will be greatly shortened.

6.reasonable deformation error;Nowadays, mechanical installation is adopted. The hole position of the circuit board and the deformation error of the circuit design should be within the allowable range.

Combined with the above six aspects of the circuit board proofing out of the measurement, it can be judged whether it is "excellent" or not.At present, there are thousands of PCB manufacturers alive in PCB proofing market, it is recommended that clients should pay more attention to the process of selection of PCB proofing suppliers and chose supplier based on a certain understanding of PCB board.

And requirements of circuit board proofing group focused on the very developed area of electronic products, mainly in shenzhen, Beijing, Shanghai, suzhou, hangzhou, xi 'an, chengdu, changsha and other cities, but with the development of China's PCB industry gradually mature, the industry growth rate tends to be stable, The PCB industry in China is undergoing structural changes, and the market share is biased towards excellent PCB manufacturers. The industry concentration is expected to be further improved.
