pcb Multilayer circuit boards Analyze the required performance of PCB boards

As the most widely used electronic component products, PCB has a strong vitality. PCB circuit board develops from single layer to double panel, multilayer board and flexible board, and continuously develops to high precision, high density and high reliability direction. Constantly reduce the size, reduce the cost, improve the performance, so that the printed circuit board in the future of the development of electronic products, still maintain strong vitality. The design of PCB circuit board mainly refers to the layout design, which requires the layout of internal electronic components, metal wires, through holes and external connections, electromagnetic protection, heat dissipation, crosstalk and other factors.

1, Maintainability: Because PCB circuit board products and various component assembly parts are standardized design and scale production, so, these parts are standardized. So, once the system failure, can be quickly, convenient, flexible replacement, quickly restore the system work. Of course, there could be more examples. Such as the system miniaturization, lightweight, high-speed signal transmission, etc.

2, high reliability: through a series of inspection, testing and aging test can ensure that PCB long-term (service life, generally for 20 years) and reliable work.

3. Assemblability: PCB circuit board products are convenient for standardized assembly of various components, and can be automated and large-scale batch production. At the same time, PCB circuit boards and various component assembly parts can also be assembled into larger parts, systems, until the whole machine.

4, productive: the use of modern management, can be standardized, scale (quantity), automation and other production, to ensure the consistency of product quality.

5, designability: PCB circuit board performance (electrical, physical, chemical, mechanical, etc.) requirements, can be standardized by design, standardization, etc., to achieve printed board design, short time, high efficiency.

6. High density: For decades, high density of printed boards can be developed with the improvement of integrated circuit integration and installation technology.

7. Testability: Complete test methods, test standards, various test equipment and instruments have been established to test and identify the qualification and service life of PCB products.

Rule 10: Generate PCB manufacturing parameters and verify them before submitting to production


While most circuit board manufacturers are happy to download it directly and verify it for you, it's best to export the Gerber file yourself and use the free reader to check that it's as expected to avoid misunderstandings.


By checking for yourself, you may even find some inadvertent errors and avoid the cost of completing production with the wrong parameters.


As circuit design becomes more widely shared and internal teams increasingly rely on reference designs, basic rules like these will continue to be a feature of PCB design and we believe they will be important for PCB design. With these basic rules in mind, developers have the flexibility to increase the value of their products and get the most out of their boards.


Just keeping these basic rules in mind can speed up the learning process and boost confidence for even new circuit board designers.

New battery protection device PCB copy board change board to improve the safety of battery pack

Diodes Incorporated recently introduced the AP9211, a battery protection device designed to enable the safe operation of single-cell lithium-ion battery packs. According to Hongyunlai Group, a professional reverse research and development center in China, the battery protection device integrates the protection chip and double N-channel MOSFET, and will provide a series of functions such as over-charge and discharge and load short-circuit detection. A few days ago, the reverse research and development center of Hongyunlai Group has successfully completed the PCB board copy and chip decryption research of this component.

According to the reverse research and development center of Hongyunlai Group technical personnel revealed that this protection circuit for battery pack production and supply of battery protection circuit module manufacturers, will be for smart phones and mobile power and other terminal market single-cell battery pack.

In the process of PCB board copy and chip decryption of AP9211 battery protection module, technicians of Hongyunlai reverse R&D Center packaged the battery protection chip and standard double N-channel co-swabp MOSFET into 3mm x 2mm six-pin U-DFN2030-6 package, which will help realize a more compact protection circuit board design. Increase the battery capacity.


In addition, Hongyunlai Reverse research and development Center not only carried out PCB board copying and chip decryption research on this battery protection device, but also carried out several secondary board modification tests, which ultimately improved the protection performance and greatly reduced the production cost. The chip will continuously monitor voltage and current to quickly turn off the MOSFETs to prevent overcharging and discharging such as load short-circuiting.

To improve the efficiency of the AP9211 components, technicians used a complementary metal oxide semiconductor (CMOS) process with a voltage of up to 30V, which is sufficient to withstand surge voltages and will also ensure high-precision voltage detection and stable temperature coefficient performance, according to Hongyunai Reverse R&D Center.

At present, the research of PCB board copy and chip decryption in the reverse R&D center of Hongyunlai Group involves communication, radar, military, medical, aerospace and other fields, which can provide a complete set of technical data and product secondary development solutions for domestic high-tech enterprises. In the past decade of research on PCB copying board and chip decryption, Hongyunlai reverse R&D engineers have accumulated rich experience in board copying and decryption, and have maintained long-term friendly cooperative relations with many domestic universities and institutes.
