How to use PCB copy board-FS Technology

PCB copy board means copying other people’s circuit boards, which is very important for a small company and can save a lot of costs. Next, FS Technology will explain the steps to you.

FS Technology PCB Copy Board Step 1: Find the circuit board

. First write down the model numbers, parameters and locations of all components on a piece of paper, especially the addresses of diodes and transistors and the notch addresses of the IC. These two assembly locations are best photographed with a digital camera, many PCBs are getting more advanced. And some of the diodes and transistors above are not visible at all.

Copy board PCB step 2: disassemble components

Take all components apart, remove the jar from the PAD hole, clean the board with alcohol. and plug it into the scanner as it scans. You’ll need to increase the scan pixels slightly to get a sharper image. Then gently wipe the top and bottom layers with gauze. Insert the scanner until the copper foil is shiny, open PHOTOSHOP, and scan the color in two layers. Note that the board should be placed on the scanner both horizontally and vertically; otherwise the scanned image will not be available.

Step 3 of copying the circuit board: Brightness comparison

Adjust the contrast and brightness of the canvas so that the copper and non-copper parts have high contrast, then change the second image to black and white to check that the lines are clear. Repeat this step when clear. Save images as TOP BMP and BOT BMP files in FS Tech black and white BMP format. If there is a problem with the image, you can use PHOTOSHOP to fix it.

PCB Plagiarism Step 4: Converting Files

Convert two BMP format files into corresponding PROTEL format files, and transfer the two layers to PROTEL. For example, after two slices, the positions of PAD and VIA are basically the same, indicating the same initial steps. .very good. clever. If there is a difference, repeat step three. So duplicating the board is a tedious job. Because small problems can affect the quality and comparison after reproduction.

Step 5 of PCB copying: conversion layer

Convert FS Technology TOP layer BMP to TOP PCB. Note the conversion to SILK layer, which is the yellow layer. You can then trace the line at the TOP level and position the device accordingly. After painting with the second step, erase the SILK layer and repeat until all layers are painted.

Step 6

Transfer TOP PCB and BOT PCB to PROTEL and merge into one image.

Step seven:

Use a laser printer to print TOP LAYER and BOTTOM LAYER separately onto transparent film (1:1 ratio). Paste the film on the FS Technology circuit board and compare whether there is any defect. If it is correct, you are done.
