The accuracy of PCB copying in the PCBA processing and production process of the chip processing factory generally depends on two important links. One is the accuracy of the pcb circuit board software, and the other is the original pcb circuit board. Image accuracy. According to the current understanding of PCB copying companies in the industry, the technical capabilities of PCB copying accuracy cannot be unified. Strong, the PCB copying accuracy can reach below 1mil, so how should the patch processing factory control the PCB copying accuracy?
For software precision, 32-bit floating point representation is usually used, so there can be said to have no precision limit, so the most important thing is to depend on the image precision of the original scan. For example, a 1-megapixel photo, a 5-inch photo can be washed out, but if you want to make a 20-inch photo, it will be completely unclear. The reason is actually the same, so for a PCB circuit board with high precision requirements, if you want to copy a PCB diagram with very high precision, choose a higher DPI when scanning.
DPI means how many points per inch. It can also be said that the distance between every two points on the scanned image is 1000/DPI, and the unit is mil. If the DPI is 400, then the distance between two points on the image is 1000/400=2.5mil, which means that the accuracy at this time is 2.5mil. This is the most scientific sis, so some people in the industry say that the accuracy can reach below 1m, which is all premised. In fact, the PCB reproduction accuracy mainly depends on the original scanning accuracy.
In summary, when the smt technology of the pcb board manufacturer sets the DPI when scanning the board, it depends on the accuracy required by the actual board. It should be set above 1000DPI. The scanners on the market can fully meet this condition and meet the standard requirements.
The higher the DPI, the clearer the picture of the pcb circuit board, and the higher the precision of the pcb circuit board, but the disadvantage of DIP is that the picture is too large and the hardware requirements are high, so it should be set according to the specific situation; the circuit board usually uses 400DPI to meet the standard Conditions, the mobile phone PCB circuit board can be set above 1000DPI.
