PCB Technical - The main process of PCBA design

The main process of PCBA design
In PCB design, in fact, before the formal wiring, it has to go through a very long step. The following is the main process of PCB design:
1. System Specifications
First, we must first plan out the various system specifications of the electronic equipment. Including system functions, cost constraints, size, operating conditions, and so on.

2. Functional block

Next, a functional block diagram of the system must be produced. The relationship between the squares must also be marked. Dividing the system into several PCBs If the system is divided into several PCBs, not only the size can be reduced, but also the system can be upgraded and exchanged parts. The system function block diagram provides the basis for our division. For example, a computer can be divided into a motherboard, a graphics card, a sound card, a floppy disk drive, a power supply, and so on.

Decide on the packaging method and the size of each PCB. When the technology and the number of circuits used in each PCB are determined, the next step is to determine the size of the board. If the PCB design is too large, then the packaging technology must be changed or re-divided. When choosing a technology, the quality and speed of the circuit diagram must also be considered.

We design (if you need), manufacture, and ship electronic products that customers need, and provide customers with one-stop comprehensive solutions to help customers get rid of cumbersome production, solve their worries, and enable customers to focus more on market business development . We deeply understand that quality, price, and delivery time play a key role in improving the competitiveness of customers in the market. We have also spared no effort to help customers achieve this goal. Excellent quality, high-quality price, and on-time delivery are our service commitments. For this reason, we have won a good reputation in the field of electronic manufacturing services and won the trust of customers, which makes customers feel relieved to hand over projects one after another. We work together.
Electronics will embrace the bright future with customers in the spirit of "striving for perfection" and "pursuing excellence". Paying attention to the trend of environmental protection informatization and the development of various environmental protection technologies, PCB factories can start with big data to monitor the company's pollution discharge and governance results, and find and solve environmental pollution problems in a timely manner. Keep up with the production concept of the new era, continuously improve resource utilization, and realize green production. Efforts to make the PCB factory industry realize an efficient, economical and environmentally friendly production model, and actively respond to the country's environmental protection policy. The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
