Analysis of problems affecting quality in PCB copy board
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
Since PCB copy board involves a problem of copy board accuracy, for circuit boards with high precision requirements such as mobile phone boards, it is necessary to copy high-precision PCB layouts. Therefore, in the scanning process, we must accurately perform the scanner The numerical value selection and setting of, also need to ensure the accuracy of the original scanned image. To be precise, the accuracy of the copy board is mainly determined by the original scanning accuracy.

In the process of PCBA processing and copying in Shenzhen, PCB scanning is undoubtedly the first step of all processes. Therefore, we first get a good PCB board, and then it must be scanned by the computer than necessary, and then back up the relevant parameters and the original PCB layout.
After disassembling the board, get the split PCB light board, it will officially enter the stage of copying the board, and the first thing we need to do is scanning. First of all, we need to store and record the PCB image. One thing to mention here is that in order to better ensure that the relevant parameters on the PCB are clearly visible after scanning, we must first remove the stains and residual tin on the PCB surface before scanning.
Here, we need to introduce a concept of DPI, where the meaning of DPI is the number of dots per inch. To be precise, the distance between every two points on the scanned image is 1000/DPI, the unit is mil. In this way, when we copy the mobile phone board, the DPI will be set to 1000 when the PCB is scanned, and the distance between two points on the image is 1000/1000=1mil, that is, the accuracy at this time is 1mil.
One thing to note in Shenzhen PCBA processing is that the higher the accuracy of the scanned picture, the larger the picture, and the higher the hardware requirements. Therefore, we need to set the DPI according to the specific conditions of the original board. Ensure that the next steps in the copy board process can exert the best results. iPCB is happy to be your business partner.
