How to use bmp2pcb: In the DOS command line, type bmp2pcb without parameters to display help information C:\SLECAD>bmp2pcb Then displays: - SLEC(R) BMP-to-TraxPCB Utility-Version 2.1 Copyright(c) BEIJING SLEC(R) 1995-1996 All rights reserved -Howard Lee - USAGE:BMP2PCB.EXE Bitmap(Black&White) file name to be converted Trax PCB file name to be convered to X (Horizontal) resolution(Default=1000) Y (Veritical) resolution(Default=1000) 0(D)-Normal 1-XMirror 2-YMirror 4-Negative Protel-PCB layer number Protel-PCB Skew Ratio Among them, the parameters in angle brackets are required options, and the parameters in square brackets are optional. Data conversion: run bmp2pcb.exe program under DOS. After the scanning is completed, exit the scanning software and make appropriate adjustments in photoshp, including adjusting the plate position, contrast, and sharpness, and finally turn it into a black and white one-bit bmp image and save it to disk. Generally, the small board uses 600dpi, and the large board uses 300dpi or more. Scanning: first install the scanner, then start the photoshp software, run the TWAIN command under Import under the File menu, start the scanner, and adjust the resolution according to the size of the circuit board. PCB copying software Bmp2 scanning copying operation 1. PCB copy boardsoftware Bmp2 system configuration Hardware: Computer: models above 486DX66, memory above 8M, support display mode above 256 colors Scanner: Optical resolution 300X600 or more, color flatbed scanner Software: SLEC copy board software: bmp2pcb.exe Scan operation interface: photoshp Circuit board design software: Protel for DOS or Protel for Windows Operating system: Windows 3.2 or Windows 95, 98 2. The system uses dot matrix data vectorization technology, which greatly improves the efficiency and accuracy of circuit board copying. The working project of Bmp2 is roughly: use a scanner to scan the circuit board image into the computer, and use the SLEC copy board tool to vectorize the dot matrix image data and convert it into a data format that can be recognized by the CAD software Protel, resulting in 1:1 Copy the base map of the board, and finally copy the circuit board in Protel according to the base map.
The text focuses on the use of Bmp2 copy boardsoftware and software related instructions. There are many kinds of PCBcopy software, such as Bmp2 and CBR5.2 commonly used.
