How to choose an urgent circuit board manufacturer

　　With the rapid development of technology, the number of circuit board manufacturers is also increasing, and various small factories are actively appearing. There are also many choices for PCB manufacturers that are really needed in the electronics industry. For urgent board circuit board production, there are also Some rules in the industry. Improve all aspects of production effects to meet the needs of rapid production.

　　PCB multilayer board refers to the layered composition of the printed circuit board: copper foil layer, printed material layer, and silk screen layer. The circuit board has a copper foil layer that includes the signal layer and internal electrical layer in the software design. The circuit board manufacturer mainly completes the electrical connection characteristics of the circuit. In PCB production, the number of layers of copper foil is usually defined as the number of layers of printed circuit boards (single-sided, double-sided, and multilayer). The printed material layer of the PCB circuit board is also called the insulating layer or the copper clad laminate. The main function of the flexible circuit board is to isolate the power layer and the wiring layer. The circuit board making machine supports the entire printed circuit board. The silk screen layer of the circuit board manufacturer is located at the top layer of the printed circuit board. The circuit board production equipment protects the copper foil layer. The printed circuit board produces and records some logo patterns and text symbols (usually white), which is the character layer.

　　The selection of the layers of the printed circuit board should be considered in terms of electrical performance, reliability, processing requirements of the circuit board manufacturer, and economic indicators. The copper clad laminates commonly used by PCB manufacturers are: phenolic paper laminate, epoxy paper laminate, circuit board factory polyester glass cloth laminate, and epoxy glass cloth laminate. The laboratory generally chooses epoxy paper laminate. It is best to use polyester glass cloth laminate for flexible circuit board UHF printed circuit boards. For electronic equipment that requires flame retardancy, the circuit board protective paint also needs to be immersed in flame retardant resin laminated flame retardant printed circuit boards . The thickness of the printed circuit board should be determined according to the function of the printed circuit board, the weight of the components installed in the pcb circuit board production equipment, the specifications of the printed circuit board socket, the external size of the printed circuit board and the mechanical load it bears.
