PCB科技 - 如何使用PCB複製軟件Bmp2？

有很多種 印刷電路板 複製軟件, 例如Bmp2.和CBR5.2常用. 本文重點介紹Bmp2的使用 複製板 軟件和軟件相關說明. Bmp2的工作項目大致是：使用掃描儀將電路板影像掃描到電腦中, 並使用SLEC 複製板 將點陣影像數據向量化並將其轉換為CAD軟件Protel可識別的數據格式的工具, 以1:1的比例複製電路板的底圖, 最後根據底圖在Protel中複製電路板. 系統採用點陣數據向量化科技, 大大提高了電路板拷貝的效率和精度.

1. 印刷電路板複製板 software Bmp2 system configuration
   Hardware: Computer: models above 486DX66, 8M以上記憶體, support display mode above 256 colors;
   Scanner: Optical resolution 300X600 or more, color flatbed scanner;
   Software: SLEC 複製板 軟件：bmp2pcb.exe
   Scan operation interface: photoshp
   Circuit board design software: Protel for DOS or Protel for Windows
   Operating system: Windows 3.2或Windows 95, 98
   2. 印刷電路板 copying software Bmp2 scanning copying operation
   1. 掃描：首先安裝掃描儀, 然後啟動PhotoHP軟件, 在“檔案”選單下的“導入”下運行TWAIN命令, 啟動掃描儀, 並根據電路板的大小調整分辯率. 通常地, 小板使用600dpi, 並且大板使用300dpi或更大. 小的. 掃描完成後, 退出掃描軟件並在PhotoHP中進行適當調整, 包括調整板材位置, 明顯的差异, 和銳度, 最後將其轉換為黑白一比特bmp影像並保存到磁片.
   2. 資料轉換：運行bmp2pcb.DOS下的exe程式.
   How to use bmp2pcb:
   In the DOS command line, type bmp2pcb without parameters to display help information
   C:\SLECAD>bmp2pcb[Enter]
   Then displays:

每個參數的含義 印刷電路板 copy software Bmp2 is as follows:
The name of the BMP file to be converted, which must be 1bit (black and white);
<印刷電路板> AutoTRAX file name after conversion;
[XRes] The resolution in the X direction of the BMP file (the default value is 1000); (must be the same as the resolution used when scanning)
[YRes] The resolution of the BMP file in the Y direction (the default value is 1000); (must be the same as the resolution used when scanning)
[Attr] 0(D)-Normal 1-X-direction mirroring 2-Y-direction mirroring 4-positive and negative reverse

2-5 :1 Mid layer -4 Mid layer
6-- :Bottom layer
7-- :Top Overlay
8-- :Bottom Overlay
9-- :Ground Plane
10--:Power Plane
11--:電路板層
12--:Keep Out layer
13--:Multi layer
[Ratio] Protel 印刷電路板 垂直修正係數. 設定該係數以校正掃描儀的垂直誤差, 通常不需要.
轉換完成後, 不能直接用於光學繪圖板. 在此基礎上, 必須使用Protel軟件再次複製.
