Basic requirements for making circuit board

The level of PCB engineering production can reflect the design level of the designer, as well as the production process capacity and technical level of the PCB manufacturer. At the same time, because PCB engineering production integrates computer-aided design and manufacturing, it requires high precision and accuracy, otherwise it will affect the electrical performance of the final electronic products on board, and may cause errors in serious cases, which will lead to the scrapping of the whole batch of PCB products, delay the contract delivery time of the manufacturer, and suffer economic losses. Therefore, as a PCB engineering producer, we must always bear in mind the importance of our own responsibility, not take it lightly, but be careful, careful, careful and serious. When dealing with PCB design documents, we should carefully check whether the received documents conform to the rules set by the designer? Can it meet PCB manufacturing process requirements? Are there any positioning marks Is the line layout reasonable? Whether the distance between line and line, line and component pad, line and through hole, component pad and through hole, through hole and through hole are reasonable and meet the production requirements. Do components conflict in 2D and 3D space Is the size of printed board consistent with the processing drawing? Whether the figure (such as icon and label) added in PCB figure will cause signal short circuit Edit and modify some undesirable lines Is there a process line on the PCB? Whether the resistance welding meets the requirements of the production process, whether the resistance welding size is appropriate, and whether the character mark is pressed on the device pad, so as not to affect the quality of the electrical assembly.
