Most features of pcb board are determined by the substrate PCB design. The substrate not only affect the product improper selection certain properties such as heat resistance , the product temperature , insulation resistance, dielectric loss fart , etc. influence the manufacturing process even beat costs of different materials to adapt different manufacturing processes dry different types of base tree costs vary widely, and thus a reasonable choice pcb substrate is an important part of the PCB design.
However, many staff are PCB design circuit design based industry, that the substrate is selected cicada pcb board manufacturing process things, and therefore the same as a professional leather and some PCB designers overlooked this point because the selection should be based on product characteristics required for use of the environment play selection to meet the requirements of the substrate , craft workers often do not understand the requirements of the design of product characteristics and therefore can not accurately grasp the material 's ability to adapt , if the improper selection of the base tree pcb board, the production out of the pcb board design is expected to reach the technical performance requirements. could cause batch of scrap PCB design.
These cases in the actual design and production have also occurred PCB design, so the pcb board design process must be carefully chosen substrate.
