  • pcb layout design(台湾硬件工程师15年经验

    PCB LAYOUT 術語解釋(TERMS)1. COMPONENT SIDE(零件面、正面)︰大多數零件放置之面。2. SOLDER SIDE(焊錫面、反面)。3. SOLDER mask(止焊膜面)︰通常指Solder mask Open 之意。4. TOP PAD︰在零件面上所設計之零件腳PAD,不管是否鑽孔、電鍍。5. BOTTOM PAD:在銲錫面上所設計之零件腳PAD,不管是否鑽孔、電鍍。6. POSITIVE LAYER:單、雙層板之各層線路;多層板之上、下兩層線路及內層走線皆屬之。7. NEGATIVE LAYER:通常指多層板之電源層。8. INNER PAD:多層板之POSITIVE LAYER 內層PAD。9. ANTI-PAD:多層板之NEGATIVE LAYER 上所使用之絕緣範圍,不與零件腳相接。10. THERMAL PAD:多層板內NEGATIVE LAYER 上必須零件腳時所使用之PAD,一般稱為散熱孔或導通孔。11. PAD (銲墊):除了SMD PAD 外,其他PAD 之TOP PAD、BOTTOM PAD 及INNER PAD 之形狀大小皆應相同。12. Moat : 不同信號的 Power& GND plane 之間的分隔線13. Grid : 佈線時的走線格點2. Test Point : ATE 測試點供工廠ICT 測試治具使用ICT 測試點 LAYOUT 注意事項:PCB 的每條TRACE 都要有一個作為測試用之TEST PAD(測試點),其原則如下:1. 一般測試點大小均為30-35mil,元件分布較密時,測試點最小可至30mil.測試點與元件PAD 的距離最小為40mil。2. 測試點與測試點間的間距最小為50-75mil,一般使用75mil。密度高時可使用50mil,3. 測試點必須均勻分佈於PCB 上,避免測試時造成板面受力不均。4. 多層板必須透過貫穿孔(VIA)將測試點留於錫爐著錫面上(Solder Side)。5. 測試點必需放至於Bottom Layer6. 輸出test point report(.asc 檔案powerpcb v3.5)供廠商分析可測率7. 測試點設置處:Setup􀃆pads􀃆stacks

  • Magenta Systems Internet Packet Monitoring Components are a set of Delphi components designed to cap

    Magenta Systems Internet Packet Monitoring Components are a set of Delphi components designed to capture and monitor internet packets using either raw sockets or the WinPcap device driver. Hardware permitting, ethernet packets may be captured and interpreted, and statistics maintained about the traffic. Uses of packet monitoring include totalling internet traffic by IP address and service, monitoring external or internal IP addresses and services accessed, network diagnostics, and many other applications. The component includes two demonstration applications, one that displays raw packets, the other that totals internet traffic. The components include various filters to reduce the number of packets that need to be processed, by allowing specific IP addresses to be ignored, LAN mask to ignore local traffic, and ignore non-IP traffic such as ARP.
