PCB Tech - What aspects should be paid attention to in pcb proofing

It has received more and more attention from enterprises. The 21st century is the era of the Internet, and electronic technology is the cornerstone of the development of the Internet, and it is also the golden age of technological development. The technical requirements brought by the advanced design and structure have put a heavy pressure on the basic equipment budget of the PCB companies that have newly entered the market. We know that a complete electronic product is formed through layers of processing. So what is the importance of PCB board proofing?

1. Quality

When choosing a circuit board company, buyers pay special attention to the quality of the circuit board. The choice of PCB board, the ink, equipment and the rigor of the staff will affect the final quality of the circuit board. The designed circuit board needs to be produced by a circuit board manufacturing company. From the first process of making the circuit board to the final process quality inspection, each process of PCB proofing must be produced in accordance with strict production processes. At the same time Each process must be equipped with corresponding testing and laboratory equipment, these process parameters and equipment can ensure the stability of the circuit board PCB quality.

2. Delivery

Nowadays, most purchasing friends have experienced such a situation: the PCB proofing delivery date promised by the circuit board company has been delayed again and again, and there are various reasons for delaying the delivery date. Many customers want to make PCB allegro, and the process of quick PCB proofing is very cumbersome. If the manufacturer fails to carry out strict management and control from the stage of ordering to the completion of production, then its production efficiency is likely to be in a low state. On the contrary, only when PCB proofing companies carry out strict process management in the production process, can they greatly improve production efficiency and ensure delivery speed.

3. Price

Purchasing friends are also concerned about the price of PCB proofing to a certain extent. In the circuit board industry, the prices are different, and purchasing friends cannot determine whether high prices are equal to high quality. Conventional factors affecting the price of circuit boards include the number of layers, board thickness, material, order quantity, surface treatment process, copper foil thickness, ink color, line width and line spacing, minimum aperture, delivery time, etc. Due to different PCB materials, production processes, different difficulties, customer needs, regions, payment methods, manufacturers and other factors, the cost of PCB manufacturing is different. In addition, PCB buyers should pay attention to one point when choosing a PCB manufacturing company. Choose from the price point of view, but to compare the strength of the circuit board company, the approximate product quotation, and the service items.

4. Proofing process

Since PCB proofing can also be carried out by a variety of different processes, in addition to finding a professional circuit board proofing manufacturer, special attention should be paid to approve the PCB proofing process used by the manufacturer to ensure the manufacturer’s process configuration It can meet the company's circuit board design and manufacturing requirements. In addition, the flying probe test can be carried out after the PCB is sampled.

The above are the points that pay special attention to PCB proofing. In addition, companies should also pay attention to good communication with the designers and operators of the proofing manufacturer when the circuit board is proofed, and carefully check the relevant when delivering the proofing materials. The packaging of files and components should not cause proofing failure or poor effect due to negligence in some minor matters.
