With the rapid progress of science and technology, more and more high and new technology are gradually integrated into the survival of many people.
The scope of application of PCB circuit boards is becoming wider and wider. This is because there are many electronic appliance materials and the products involved will all use professional printed circuit boards.
And for smart electronic products,high-quality PCB circuit boards can enhance the circuit stability of the product, so the overall performance of the product can be extremely optimized.
The following are the necessary conditions for high-quality circuit boards in my opinion.
1. The appearance is bright, clean and flat. Regardless of whether it is a semi-finished product, the first thing to consider when weighing the quality of the PCB circuit board is its appearance. The surface of the printed circuit board must be clean and flat, and the wiring inside must be reasonable and smooth. The substrate must not show the problems of bending deformation and pits, and must not show the problems of cracks, scars and ink peeling.
2. The thermal expansion coefficient is small. The thermal expansion coefficient is also very important. High-quality PCB circuit boards must have a relatively stable shape, and can shrink and expand rapidly under the influence of hot and cold background, so the thermal expansion coefficient needs to be controlled within a small range, and the inconvenience will be harmful The product position and application effect of the printed circuit board. As a result, the electronic components on the substrate were severely damaged.
3. The circuit layout is reasonable, dexterous and clever. All are called circuit boards, so the tightness of the circuit layout doesn't need me to say more, hehe. After thinking about the problem to the power supply of electronic products and making various responses after giving instructions, all responses must be completed with the help of printed circuit boards, so high-quality PCB circuit boards will require a pre-defined circuit plan that meets the regulations. It can be considered that the problem is preset into single, double-sided and multi-layer boards according to the complexity of electronic products, but no matter which type of printed circuit board is selected, there must be very accurate control of the circuit and the required layout trend to avoid The phenomenon of stuck due to redundant lines is revealed.
4. Good heat resistance. The heat resistance of the circuit board is crucial for weighing its quality. After receiving the PCB circuit board, the customer still needs to assemble it into the goods they need. The most commonly used method in the assembly process is soldering. Therefore, high-quality printed circuit boards also require heat-resistant requirements. And it is necessary to be able to think about the instantaneous high temperature that occurs when the problem bears the welding.
The above is the partial standard that high-quality circuit boards must have. It can be seen that the size of a printed circuit board is small but it should not be underestimated. Therefore, the company must first find a good PCB circuit board manufacturer to ensure that the processed printed circuit board can be considered in many aspects. Corresponding standards ensure the product position of PCB circuit boards.
