Embodiment Construction

[0019] The present invention provides a kind of efficient PCB circuit board duplication method, and specific operation process is as follows:

[0020] Step 1: First record the models, parameters, and positions of all components on paper, especially the direction of diodes, tri-motor tubes, and IC notches. It is best to take two photos of the component location with a digital camera.

[0021] Step 2: Remove all components and remove the tin in the PAD hole. Clean the PCB with alcohol, and then put it into the scanner. When the scanner scans, you need to increase the scanning pixels slightly to get a clearer image. Start POHTOSHOP, scan the silk screen in color, and save the file and print it out for later use.

[0022] Step 3: Lightly polish the two layers of TOP LAYER and BOTTOM LAYER with water gauze paper until the copper film is shiny, put it into the scanner, start PHOTOSHOP, and scan the two layers in color. Note that the PCB must be placed horizontally and straight in...

Abstract

The present invention relates to an efficient PCB circuit board replication method, including steps: first of all, recoding the characteristics of all components on paper; scanning-in the silk-screen surface in a chromatic mode, preserving the file and printing for standby; using water yarn papers to lightly sand the two layer (TOP LAYER and BOTTOM LAYER), and respectively scanning-in the two layers in a chromatic mode; respectively converting two BMP format files into PROTEL format files, calling two layers in the PROTEL for fundamental coincidence of the PAD and VIA positions of the two layers; converting the BMP of the TOP and BOT layers into TOP.PCB; finally calling the TOP.PCB and BOT.PCB in the PROTEL, to combine as one single map. The present invention principally solves the technical problem in the prior art that each through-hole and solder pad are need to be located by manual measuring, and further improves the reproductive work efficiency of the PCB circuit without limitation of the tight circuit of the PCB circuit.

Description

technical field [0001] The invention relates to a printed circuit board (Printed circuit board, PCB), in particular to an efficient method for duplicating a PCB circuit board. Background technique [0002] The copying of the PCB circuit should be consistent with the original board, that is, follow the gourd painting, and the requirements for operators are not as high as the design. But copying also has the difficulty of copying, that is, it is trivial and labor-intensive. [0003] When copying the original PCB circuit, each via and pad must be manually measured and positioned, which is very laborious. As the existing PCB boards become more and more sophisticated. It is no longer possible to measure with a film ruler and a magnifying glass, such as Bluetooth boards with 3mil line width and line spacing; mobile phone boards with very high positioning requirements. [0004] Therefore, the original PCB circuit duplication method is no longer used in the current PCB circuit du...
