20 years of PCB experice and specilize in protype and small volume
PCB circuit boards are almost inseparable from the electronic devices we can see, ranging from electronic watches, calculators, general-purpose computers, computers, communication electronic devices, military weapon systems, as long as there are electronic devices without integrated circuits. PCB boards are used for electrical interconnection between them. It provides mechanical support for fixed assembly of various electronic components such as integrated circuits, realizes wiring and electrical connection or electrical insulation between various electronic components such as integrated circuits, and provides required electrical characteristics such as characteristic impedance. At the same time, it provides solder mask pattern for automatic soldering; it provides identification characters and graphics for component insertion, inspection and maintenance. So how is the PCB board made? The Flexible PCB Circuit Board Supplier will tell you next.
When we open the keyboard of a general-purpose computer, we can see a soft film (flexible insulating substrate) printed with silver-white (silver paste) conductive patterns and graphic patterns. Because the universal screen printing method obtains this pattern, we call this printed PCB circuit board a flexible silver paste printed PCB circuit board. The printed circuit boards on the various computer motherboards, graphics cards, network cards, modems, sound cards and home appliances that we see in Computer City are different. The substrate used is paper-based (usually used for single-sided) or glass-based (usually used for double-sided and multi-layer), pre-impregnated with phenolic or epoxy resin, and coated on one or both sides of the surface to be laminated and cured. Made. This kind of PCB circuit board is a rigid board. To make a printed PCB board, we call it a Rigid Flex PCB Design.
Rigid Flex PCB Design
Printed circuit graphics on one side We call a single-sided printed circuit board, printed circuit patterns on both sides, and printed circuit boards formed by double-sided interconnection through metallization of holes. We call it a Double Sided PCB. If a double-sided inner layer, two single-sided outer layers or two double-sided inner layers and two single-sided outer printed circuit boards are used, the positioning system and the insulating bonding material are alternately The printed circuit boards in which the conductive patterns are interconnected according to the design requirements become four-layer and six-layer printed circuit boards, which are also called multi-layer printed circuit boards.
There are now more than 100 layers of practical printed PCB boards. PCB board PCB production process is more complicated, it involves a wide range of processes, from simple machining to complex machining, common chemical reactions and photochemical electrochemical thermochemistry, computer-aided design cam And so on. Moreover, there are many technical problems in the production process and new problems will be encountered from time to time. Some problems will disappear if the cause is not found out. Because the production process is a non-continuous pipeline form, any problem will cause the whole line to be discontinued. Or the consequences of a large number of scraps, if the printed circuit board can not be recycled and reused, the work pressure of the process engineer is large, so many engineers left the industry to transfer to the printed circuit board equipment or materials business to do sales and technical services.
