    PCB manufacturers analysis of circuit boards by layer number can be divided into several categories?

    12:58, Tuesday 10 September 2019 | 0 commentaires | Lien
    According to the number of layers, the circuit board is divided into three major categories: single panel, double panel, and multi-layer circuit board. The first is a single panel. On the most basic PCB, the parts are concentrated on one side and the wires are concentrated on the other side. Because the wire only appears on one side, it is called a single-sided circuit board. Single panels are usually simple to make and low in cost, but the disadvantage is that they cannot be applied to products that are too complicated. The double panel is an extension of the single panel. When the single layer wiring cannot meet the needs of the electronic product, the double panel is used. Both sides have copper-clad traces, and the via can be used to turn on the lines between the two layers to form the desired network connection. A multi-layer board refers to a printed board having three or more layers of a conductive pattern layer and an insulating material interposed there between, and the conductive patterns there between are interconnected as required. Multi-layer circuit boards are the product of the development of electronic information technology in the direction of high speed, multi-function, large capacity, small volume, thinning and light weight. see more https://www.lhd-pcb.com/pcb-manufacturing-Service.html

    Why is it important to choose a PCB board supply chain?

    First of all, we must choose a high-end product with stable quality and trustworthy company. This is the main point of purchasing a reliable circuit board, because customers not only have the requirements for the quality of the circuit board, but also the delivery date of the ordered products. Required. Choosing a Shenzhen circuit board company that has been verified by many customers and has stable product quality and trustworthiness, customers no longer have to worry about quality and delivery, and thus can accelerate the R&D and production process of their own enterprises. Second, we must choose a reliable circuit board. At present, the circuit boards on the market can be made of many materials, and the quality between the good and the bad materials is very different. Therefore, customers must pay attention to the selection of Shenzhen circuit boards made of high-quality raw materials when purchasing, thus ensuring the assembly of Shenzhen lines. All kinds of instruments and equipment of the board can respond to various use environments stably and efficiently. Finally, the level of technology is also related to the quality of the board. The circuit board is a product whose details determine the quality is very obvious. The well-received Shenzhen circuit board not only pays attention to the etching process of the surface of the circuit board, but also pays attention to the details such as drilling of the circuit board and plating in the hole. The good process level guarantees that Shenzhen circuit boards can cope with various application requirements, and also greatly improve the quality of customer products. The shape of the circuit board used in each company's products is different, so choosing a stable and durable Shenzhen circuit board has become an important factor that directly determines the stability and stability of the product. Therefore, customers must compare and repeatedly choose one of the most reliable circuit manufacturers in Shenzhen, and finally achieve the improvement of quality control and sales growth. see more:http://www.lhd-pcb.com

    How to judge the quality of multi-layer PCB board from color

    source: http://www.lhd-pcb.com How to judge the quality of multi-layer PCB circuit boards from PCB color. Today, let's explain how the color of the PCB affects its performance. How should we judge the quality of multi layer PCB boards? First, the PCB acts as a printed circuit board and mainly provides interconnection between electronic components. There is no direct relationship between color and performance. The difference in pigment does not affect the performance of the appliance. However, whether the performance of the PCB is good or bad is determined by the materials used (high Q), wiring design and several layers of boards. In the process of washing the PCB, black is the most likely to cause chromatic aberration. If the raw materials and manufacturing processes used in the PCB factory are slightly deviated, the PCB defect rate will increase due to chromatic aberration. This directly leads to an increase in production costs. In fact, the raw materials of PCB are everywhere in our daily life, that is, glass fiber and resin. The glass fiber is combined with the resin and hardened to become a board that is insulated, insulated, and not easily bent. This is the PCB substrate. Of course, a PCB substrate that is made up of glass fiber and resin cannot transmit signals. Therefore, on a PCB substrate, the manufacturer will cover a layer of copper on the surface, so the PCB substrate can also be called a copper-clad substrate. Since the black PCB's circuit traces are difficult to identify, it will increase the difficulty of repair and debugging during the R&D and after-sales phases. Generally, if there is no strong RD (R&D) designer and a strong maintenance team, the black PCB will not be easily used of. It can be said that the use of black PCB is a brand's confidence in the RD design and the post-maintenance team. From the side, it is also a manifestation of the manufacturer's self-confidence. The color of the PCB is also a matter of learning. For these reasons. Many manufacturers are designing PCB boards for their products, and they will carefully consider the colors.
