Electronic Components Supplier Integrated Circuit LM2904 ADS8341E/2K5 OPT3001IDNPRQ1 TPS79101DBVRG4Q1 chip

1.Kodi bonding ndi chiyani (chip bonding ndi bonding)

kugwirizana ndi njira yolumikizirana mukupanga tchipisi, yomwe imagwiritsidwa ntchito kulumikiza mayendedwe amkati a chip ndi mapini a phukusi ndi waya wagolide musanayambe kulongedza, ndipo nthawi zambiri pambuyo polumikizana (ie pambuyo polumikizana ndi zikhomo) chip ndi atakulungidwa ndi gel osakaniza wakuda ndikugwiritsa ntchito ukadaulo wapamwamba wakunja wa COB (ChipOnBoard), njirayi iyenera kuyesa chowotcha cha epitaxial chomwe chimayikidwa mu bolodi lapadera ladera, kenako epitaxial wafer circuit yolumikizidwa ndi board board ndi waya wagolide, kenako kusungunuka. ndi ntchito yapadera yotetezera ya zinthu zakuthupi zophimbidwa ndi zowotcha za epitaxial kuti amalize kutsekemera kwa chip.

2.Kodi semiconductor ndi chiyani?

Tiyeni tiyambe ndi zomwe semiconductor ndi.Kuchokera kuzinthu zakuthupi: semiconductor ndi zinthu zomwe zimakhala ndi conductive pakati pa za conductor ndi insulator kutentha kutentha.Monga m'moyo watsiku ndi tsiku, mawaya amkuwa ndi aluminiyamu ndi ma conductor, pomwe mphira ndi zina zotere ndi zoteteza.Pankhani yamagetsi amagetsi: semiconductor ndi zinthu zomwe zimayendetsedwa ndi magetsi, kuyambira insulator mpaka conductor.

Zinayi za semiconductors.

Kupezeka kwa ma semiconductors kungayambike mpaka 1833, pomwe Faraday, wasayansi waku Britain, komanso bambo wa zamagetsi, anali woyamba kupeza kuti kukana kwa silver sulfide kumasiyanasiyana ndi kutentha kosiyana ndi zitsulo wamba, zomwe zinali zoyamba. Kuzindikira kwa semiconductor phenomenon.

Koma chidule cha katundu wa semiconductors sichinamalizidwe mpaka December 1947 ndi Bell Laboratories.

Kutentha kumakwera, ndipo kukana kumagwa: kukana kwa semiconductor kumachepa pamene kutentha kumakwera, koma, kawirikawiri, kukana kwachitsulo kumawonjezeka ndi kutentha.

Photovoltaic effect: mphambano yomwe imapangidwa polumikizana pakati pa semiconductor ndi electrolyte imatulutsa mphamvu yamagetsi ikayatsidwa.

Mphamvu ya Photoconductive: kuwongolera kwa semiconductor kumawonjezeka pamaso pa kuwala.

Kusintha kwamphamvu: kuwongolera kwa semiconductor ndikolunjika komanso kogwirizana ndi komwe kumayendera magetsi.Onjezani voteji yabwino kumapeto kwa semiconductor ndipo imayendetsa;ngati polarity yamagetsi yasinthidwa, sizothandiza.
