The Process in copying PCB Boards The second step is to raze all device and also the PAD holes within the tin. PCB boards clean with alcohol, so place into the scanner, the scanner to scan the time must be somewhat higher scan pixels, so as to urge a transparent image, begin PHOTOSHOP, knocked screen printing surface into color method, save the file and print it out for later use.

The third step, water gauze paper can prime LAYER and BOTTOM LAYER 2 layers of slight grinding, sharpening to copper film, into the scanner, begin PHOTOSHOP, knocked 2 layers severally into in color mode Rigid flex Board. Give proper attention to the circuit board design in the first place within the scanner should cross straight trees, or scan pictures cannot use, and save the file.

The fourth step, regulate the distinction of the canvas, the distinction, the copper film a part of and not part of the copper film distinction, then the primary figure to black and white, check whether or not the road is evident, if not clear, repeat this step. If clear, it can survive for the black and white prime. The BMP file format of BMP and larva. BMP, if found issues graphics may also use PHOTOSHOP to repair and correction.

Fifth, the 2 BMP format into PROTEL format file, severally in PROTEL transfer into 2 layers, like a 2 layer of the PAD and also the location of the VIA basic coincidence, suggests many steps before doing an honest job, if there's a deviation, then repeat step three.
Sixth, TOP. The highest layer of BMP is born-again to PCB, take care to into a SILK layer, the layer is yellow, so you only at the highest layer tracing, and drawing device per the second step. Then the draw can delete the SILK layer.

Step 7, BOT layer of BMP can be transformed to the PCB, be careful while putting into a SILK layer China PCB Prototype, the layer is yellow, and then you in the BOT layer tracing it. After the draw it will delete the SILK layer.

Step 8, Top in PROTEL PCB and larva. PCB paged, into a graph with regard to OK.
Step 9, use electrostatic printer to prime LAYER, BOTTOM LAYER severally written on clear film (1:1 ratio), place the film on the PCB board, compare the errors, if yes, you are done.
Other: if it's a multilayer and thoroughly polished within lining, repeat steps three to nine, at a similar time, of course, the naming of graphics is completely different additionally, wish to be determined per the quantity of layers, the final double panel is far less complicated than a multilayer copy board, laminated copy plate vulnerable to alignment, look at the professional and advanced circuits carefully.
