pcb proofing makesthe circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization of electrical layout.

  Dual-disk is an extension of single-disk. When single-layer wiring cannot meet the needs of electronic products, dual-disk is used. Both sides are covered and wired, and the wiring between the two layers can pass through holes to form the required network connection.
   should pay attention to appearance
   The quality of PCB is evaluated from the aspects of PCB soldering, light, color, board size and thickness. Therefore, PCB multi-layer PCB proofing manufacturers should start with these aspects and carefully complete the appearance requirements of PCB proofing.
   should pay attention to staffing

In the proofing process, each process requires special technical personnel to supervise and control, and is responsible for inspecting the production circuit boards of each process. At the same time, after the product is completed, special personnel are required to conduct a comprehensive inspection or sampling inspection, in order to ensure the pcb Proofing quality of multi-layer circuit boards.
   should pay attention to the selection of materials
   At present, one side and a half glass plate is a good quality raw material, with good strength, both sides are green, and copper coating has no peculiar smell. Compared with other plates, the cost is slightly higher. If the price of HB plate is favorable, there will be phenomena such as line change and breakage, and the quality of proofing will be rougher.
