  • PCB LAYOUT初學(xué)者必看!

    PCB LAYOUT技術(shù)大全---初學(xué)者必看!  PROTEL相關(guān)疑問(wèn) 1.原理圖常見(jiàn)錯(cuò)誤: (1)ERC報(bào)告管腳沒(méi)有接入信號(hào): a. 創(chuàng)建封裝時(shí)給管腳定義了I/O屬性; b.創(chuàng)建元件或放置元件時(shí)修改了不一致的grid屬性,管腳與線沒(méi)有連上; c. 創(chuàng)建元件時(shí)pin方向反向,必須非pin Name端連線。 (2)元件跑到圖紙界外:沒(méi)有在元件庫(kù)圖表紙中心創(chuàng)建元件。 (3)創(chuàng)建的工程文件網(wǎng)絡(luò)表只能部分調(diào)入pcb:生成netlist時(shí)沒(méi)有選擇為global。 (4)當(dāng)使用自己創(chuàng)建的多部分組成的元件時(shí),千萬(wàn)不要使用annotate. 2.PCB中常見(jiàn)錯(cuò)誤: (1)網(wǎng)絡(luò)載入時(shí)報(bào)告NODE沒(méi)有找到: a. 原理圖中的元件使用了pcb庫(kù)中沒(méi)有的封裝;  b. 原理圖中的元件使用了pcb庫(kù)中名稱(chēng)不一致的封裝; c. 原理圖中的元件使用了pcb庫(kù)中pin number不一致的封裝。如三極管:sch中pin number 為e,b,c, 而pcb中為1,2,3。
