左圖為麵包板外觀示意圖。         右圖為麵包板內部電路示意圖。

  • 麵包板
    • 用於編排測試電路的底板,通常會將各種元件與杜邦線插在上面
    • 上下兩排線路較長且為橫向接通,通常用來接電源與接地
    • 中間區塊線路較短且為豎向接通,是主要安排電路的位置

上圖為公對母杜邦線示意圖,左下端為母頭,右上端為公頭

  • 杜邦線
    • 用於連接測試電路,兩端各自可能為公頭也可能為母頭
    • 公頭:連接母頭、麵包板與各種元件的母座
    • 母頭:連接公頭或各種元件的針腳

DIT 團隊自己 layout 的PCB板

  • 簡介
    • 全名為印刷電路板(Printed Circuit Board)
    • 將金屬導體用印刷方式在絕緣底板上配置電路
      • 後續常焊接上細碎元件、針腳再進行生產、使用
    • 優點
      • 簡化製作步驟
      • 減少零件間配線
      • 提高線路密度
      • 高生產穩定性
  • 實際使用
    • 確定好電路配置時,才會進行編排、layout
    • 應用方向:模組化、工廠大量生產
      • 常在各種電子產品、元件內見到
