monga PCB yogwiritsidwa ntchito ndi zida zamagetsi zosiyanasiyana zimachulukirachulukira, kuzindikira vuto la kubwerera kwa PCB pamanja kumangokhala kovuta komanso kumatsimikizika pang’ono. Woyesera wa AUTOMATIC wa ndege ya PCB yozikidwa pa PLD yomwe yatulutsidwa mu pepalayi akhoza kupititsa patsogolo magwiridwe antchito ndikuwonetsetsa kudalirika kwake.

Ndi chitukuko chofulumira chaukadaulo wamagetsi, chimagwiritsidwa ntchito m’njira zosiyanasiyana zamagetsi zamagetsi zosindikizidwa (PCB) zawonjezeka kwambiri, ogwira ntchito zaukadaulo ayenera kuzindikira msana kumbuyo kwa dera lalifupi, kutseguka kwa dera lotseguka kapena kukonza zochulukirapo kukana, ngati kudalira kuzindikira kwa anthu kumakhala kovuta kwambiri, komanso kudalirika kumakhala kotsika, kotero oyang’anira dera amabwerera mowonjezeka kufunikira kwa kuyesa kwazokha. M’pepalali, njira yoyeserera yoyesera ya PCB yonyamula potengera EPM7128 control multiway selector switch ADG732 ikufunsidwa, ndikukhazikitsa kwake kumaperekedwa. Zimatsimikizika kuti njira yoyeserayo ndiyachangu komanso yothandiza mukayigwiritsa ntchito poyesa PCB kumbuyo.

Zida zamagetsi

Kapangidwe kazoyeserera kokhako kamawonetsedwa mu Chithunzi 1, chomwe chimakhala ndi microcomputer, USB bus DIO interface interface, PLD block block, multi-way selection switch, test fixture ndi zina zotero.Njirayi imatha kuyesa zolakwika zazifupi komanso zazifupi zazingwe za PCB zosakwatiwa, ziwiri komanso zingapo.

Ma Microcomputer alibe zofunikira zapadera, ndipo amatha kugwiritsa ntchito makompyuta wamba. Mawonekedwewa amagwiritsa ntchito template yotsika mtengo ya USB-7802ADIO yopangidwa ndi Hongtop Measurement and Control Technology Co, LTD. Mphamvu yolowera ndi kutulutsa ndi 0 ~ 5V, mogwirizana ndi USB bus + 5V standard. Usb-7802a ndi bolodi yolowetsa / yotulutsa ma digito makumi atatu ndi mphambu zitatu, yomwe ili ndi madoko 32-bit a digito olowetsera digito ndi madoko 4-bit-latch latch latch port, zolowetsa 8 ndi zotuluka 4; Amapereka win95 / 98/2000 / NT pansi pa pulogalamu yoyeserera ndi pulogalamu yolumikizana mwamphamvu (DLL).Popeza ndiyabasi ya USB, pulogalamu ya USB imangoyambitsa adilesi yoyambira.
