華碩電腦pcb設計規(guī)范,內(nèi)部資料, PCB Layout Rule Rev1.70, 規(guī)範內(nèi)容如附件所示, 其中分為: (1) ”PCB LAYOUT 基本規(guī)範”:為R&D Layout時必須遵守的事項, 否則SMt,DIP,裁板時無法生產(chǎn). (2) “錫偷LAYOUT RULE建議規(guī)範”: 加適合的錫偷可降低短路及錫球. (3) “PCB LAYOUT 建議規(guī)範”:為製造單位為提高量產(chǎn)良率,建議R&D在design階段即加入PCB Layout. (4) ”零件選用建議規(guī)範”: Connector零件在未來應用逐漸廣泛, 又是SMt生產(chǎn)時是偏移及置件不良的主因,故製造希望R&D及採購在購買異形零件時能顧慮製造的需求, 提高自動置件的比例. (5) “零件包裝建議規(guī)範”:,零件taping包裝時, taping的公差尺寸規(guī)範,以降低拋料率.

Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The 34401A may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the 34401A may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that may exceed the protection limits of the 34401A. Note: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, transient overvoltages are also present on circuits that are isolated from mains. The Agilent 34401A are designed to safely withstand occasional transient overvoltages up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltages could exceed this level.
