PCB copy board, DIY, you can also 【PCB copy board】
Update date：2012-6-22
Many people find the copy board is a very mysterious thing, in fact, the copy board is very simple, you can learn, the Shenzhen East conduction technology is a professional copy board, and PCB copy board company with a senior copy board engineers, in order to promote the entire electronics industry, and summarizes some of the steps of copy board and points are summarized below and share with you. The first step when you get a piece of the PCB, the first record on paper all the components of the model parameters, and position, especially in the direction of the diodes, transistors, IC gap direction. Best to shoot photos of the two components location with a digital camera or a scanner. The second step to remove all devices, and PAD hole in the tin remove. With alcohol the PCB is cleaned and then placed in the scanner, start POHTOSHOP, swept into the color screen printing surface, and print out the spare, pay attention to the preservation of information. The third step of water paper yarn LAYER TOP and BOTTOM LAYER two layers of slightly polished, polished shine to copper film into the scanner, start PHOTOSHOP, two layers were swept into the color. Note the PCB placed in the scanner must be cross-level tree straight, or scanned images can not be used. The fourth step to adjust the canvas, contrast, brightness, so that there is a strong part of the copper film and copper film part of the comparison, then this figure converted to black and white, check the lines are clear, if it is not clear, repeat this step. If clear, the survival for black and white BMP format file TOP.BMP and BOT.BMP. The fifth step of the two BMP format file into PROTEL format in PROTEL transferred to a two-tier, if the two layers of the PAD and VIA's position essentially coincident, indicating that the first few steps to do well, if there are deviations The third step is repeated. Step 6 TOP.BMP conversion for TOP.PCB Note to be converted to SILK layer is that layer of yellow, then it wants in the TOP layer of scanning lines, and placed under the second step of drawing devices. Unfinished after the SILK deleted. The seventh step BOT.BMP conversion for BOT.PCB Note to be converted to SILK layer is that layer of yellow, and then you describe the BOT layer line it wants to. Unfinished after the SILK deleted. Step 8 in the PROTEL will TOP.PCB and BOT.PCB transferred, or as a graph on OK. A laser printer for the ninth step of the TOP LAYER LAYER BOTTOM. Print to transparencies (1:1 ratio), the film into a piece of the PCB, a comparison is wrong, and if yes, you're done. Seen from the above PCB copy board is not difficult, difficult, step in place, the whole process can not go wrong and need to be careful, of course, perfect skilled, Shenzhen East guide technology has been copied to the board for the past eight years, ever copied the board, excluding the number, from a single panel of more than 10 layers board, cardboard, glass plate, aluminum plate to a number of high-frequency board, Mobile and PC board ... it can be said now is basically the level reached a pinnacle, if you need to copy board encounter, or copied on top of confusion, please contact the East guide technology.
