FatFs06.rar
FatFs is a generic file system module to implement the FAT file system to small embedded systems. The FatFs is written in compliance with ANSI C, therefore it is independent of hardware architecture. It can be incorporated into cheap microcontrollers, such as 8051, PIC, AVR, SH, Z80, H8, ARM and etc..., without any change.

PCB Layout Rule Rev1.70, 規(guī)範(fàn)內(nèi)容如附件所示, 其中分為:
(1) ”PCB LAYOUT 基本規(guī)範(fàn)”:為R&D Layout時(shí)必須遵守的事項(xiàng), 否則SMT,DIP,裁板時(shí)無法生產(chǎn).
(2) “錫偷LAYOUT RULE建議規(guī)範(fàn)”: 加適合的錫偷可降低短路及錫球.
(3) “PCB LAYOUT 建議規(guī)範(fàn)”: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(fàn)”: Connector零件在未來應(yīng)用逐漸廣泛, 又是SMT生產(chǎn)時(shí)是偏移及置件不良的主因,故製造希望R&D及採(cǎi)購(gòu)在購(gòu)買異形零件時(shí)能顧慮製造的需求, 提高自動(dòng)置件的比例.
(5) “零件包裝建議規(guī)範(fàn)”:,零件taping包裝時(shí), taping的公差尺寸規(guī)範(fàn),以降低拋料率.
