Chip Otsutsa amagwiritsidwa ntchito kwambiri mu ukadaulo wamagetsi wamagetsi.
Ndiwo fanitsiro cha zotulutsa wamba zotsutsana, koma kukhala ndi mwayi wofunika - kukula. Kugwiritsa ntchito zida izi zomwe zimakupatsani mwayi wopanga ma computing njira yamakono ndi njira zamagetsi.
Amafunsira ku ukadaulo wa SMT, womwe umadziwika ndi zochita zapamwamba kwambiri za kukhazikitsa ma boloni osindikizidwa.
Kuti apange chip oletsa, gwiritsani ntchito filimu yocheperako kapena yaukadaulo, ndipo zida zili ndi magawo osiyanasiyana olakwika. Mitengo yodziwika bwino ndi 5% kapena 1%, komanso yolondola pafupifupi 0.01%.
Amagwiritsidwa ntchito mu zida zamankhwala ndi zoyezera, zamagetsi ndi zamagetsi zamagetsi, zida zosiyanasiyana za pacombala, magetsi, ndi zida zina. Pali zigawo zambiri za zida zosiyanasiyana, pakati pawo:
- Tolstopnoe;
- Mphamvu yotsika kwambiri yomwe imagwiritsidwa ntchito kudziwa mphamvu yapano;
- kanema wolondola ndi mawonekedwe okhazikika;
- Kuwononga;
- Zosintha;
- Msonkhano;
- Kuchuluka kwa magetsi kwambiri.
Mawonekedwe a Chip Kutsutsa
Kuyang'ana muyeso wowonetsera chip otsutsa, ndikofunikira kuganizira za chizindikiro chawo. Pafupifupi onse otsutsa, kupatula kukula kwa 0402, amalembedwa.
Zida zing'onozing'ono zilibe kulemba, chifukwa siziri malo pomwe zingatheke kuyika. Ngati kukula kupitirira 0805, kulembera kumayikidwa pa chogonja, chomwe chili ndi manambala atatu.
Amadziwika kuti chip ndi kulolera 10%, 5%, komanso 2% yolembedwa manambala atatu oyamba. Chiwerengero chilichonse chimatanthawuza tanthauzo lokhazikika. Nambala yomaliza pamaziko akuwonetsa kuchuluka kwa omata.
Pomwe mawerengero awiri oyamba afotokozere mantissa. Kusankha mfundo yanthawi yayitali, nthawi zina kalatayo R. imawonjezeredwa manambala. Zikakhala kuti zikuyenda 242 mawu osankhidwa 24x102, ndipo ili ndi 2.4 com.
Kutengera kulolerana, mitengoyo imatha kupatukana mu mizere ingapo E6, E12, komanso E24. Ngati kulekerera kukana ndi kochepa, mu zingapo kuposa zipembedzo.
Magetsi okwanira chip otsutsa ndi 200v. Kuchulukaku kumakhalanso ndi otsika popewa kuyika kosavuta. Ichi ndichifukwa chake potumiza mphamvu yamagetsi, mwachitsanzo 500v, ndikofunikira kuyikapo zingapo zomwe zalumikizidwa.
