What are the steps for circuit board copying
.Scan the circuit board picture Note: Since there may be small patch components under the large components, you can scan first and then remove the big ones and scan again
.Disassemble the board : Remove all components and remove the tin from the holes. Clean B with washing water, and then put it into the scanner. When scanning, the scanner selects appropriate pixels according to the precision of the board in order to get a clearer image. Start scanning the silk screen surface in color mode and save the file. And print it out for later use
3. Make B-sheet: Refer to the circuit board picture in the first step and record the model, parameters, and location of all vitality parts on paper, especially the direction and gap of the diode and triode. direction, etc., and finally make Form B
. Polish the two layers R and R lightly with water gauze paper until the copper film shines, put it into the scanner, start using color mode to scan the two layers in separately
. Adjust the contrast and lightness of the canvas so that the part with copper film and the part without copper film are in strong contrast. Then convert the image to black and white and check whether the lines are clear. If not, repeat this step. If it is clear, save the picture as a black and white B format file. B and BB. If you find problems with the graphics, you can use them to repair and correct them.
.Start the B board copying software and load the scanned B board picture in the file menu, convert the two B format files into R format files respectively, and transfer two layers in R, such as the sum of the two layers The positions basically coincide, indicating that the first few steps have been done well. If there is a deviation, repeat the first step.
.Convert the B of the layer to .B, pay attention to convert it to the layer, and then just trace the line on the layer, and place the device according to the drawing in the second step. Delete the layer after painting.
.Convert the B of the B layer to BB, as above, convert it to the layer, and then just draw the line on the B layer. Delete the layer after painting.
.Insert .B and BB into R and combine them into one graph.
.Use a laser printer to print the proportions of R onto the transparent film respectively), put the film on the piece of B, and compare whether there is an error. If it is correct, a simple double-sided panel will be made!< br/> Zhongtian Yuan Circuit Board Co., Ltd. is a high-tech enterprise in Zhengzhou specializing in the R&D, production and processing of B circuit boards, multi-layer printed boards, and aluminum substrates
