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, remove the big ones and scan again.
.Remove them Board: Remove all components and remove tin from holes. Clean B with washing water, and then put it into the scanner. When the scanner scans, select the appropriate pixels according to the precision of the board to get a clearer image. Start it, scan the silk screen surface in color, and save the image. Print the file and save it for later use
. Make a B-list: 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 Table B
. Polish the R and BR layers lightly with water gauze paper until the copper film shines, put it into the scanner, start it, and scan the two layers in color separately< br/> . 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 r, load the scanned B board picture in the file menu, convert the two B format files into R format files respectively, and load two layers in R, such as two layers The positions of and basically coincide, indicating that the previous 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 the layer as above, and then just draw the line on the B layer. Delete the layer after painting.
.Add B and B into R and combine them into one graph.
. Use a laser printer to print R and BR on transparent film respectively (ratio of :), put the film on the piece B, and compare whether there is an error. If it is correct, a simple double-sided panel will be made. It’s out!
