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

1.Dab tsi yog bonding (chip bonding thiab bonding)

Kev sib txuas yog ib txoj hauv kev sib txuas hauv cov txheej txheem tsim cov nti, feem ntau yog siv los txuas cov kab hluav taws xob sab hauv ntawm cov nti mus rau cov pob pins nrog cov hlau kub ua ntej ntim, thiab feem ntau tom qab kev sib txuas (piv txwv li tom qab circuitry txuas nrog cov pins) cov nti yog encapsulated nrog ib tug dub gel thaum siv cov txheej txheem ntim txheej txheem COB (ChipOnBoard), cov txheej txheem no yog yuav tsum tau kuaj cov epitaxial wafer cog rau hauv lub rooj tsavxwm tshwj xeeb, tom qab ntawd cov kab hluav taws xob epitaxial wafer txuas nrog lub rooj tsavxwm nrog kub hlau, thiab tom qab ntawd yaj. nrog rau kev tiv thaiv tshwj xeeb ntawm cov khoom siv organic npog nrog epitaxial wafers kom ua tiav cov txheej txheem tom qab-encapsulation ntawm cov nti.

2.Dab tsi yog semiconductor?

Cia peb pib nrog dab tsi yog semiconductor.Los ntawm cov khoom taw tes ntawm view: ib tug semiconductor yog ib yam khoom uas muaj conductive zog ntawm cov neeg xyuas pib thiab ib tug insulator ntawm chav tsev kub.Zoo li nyob rau hauv lub neej niaj hnub, tooj liab thiab txhuas hlau yog conductors, thaum roj hmab thiab cov zoo li yog insulators.Nyob rau hauv cov nqe lus ntawm hluav taws xob conductivity: ib tug semiconductor yog ib yam khoom uas tswj hluav taws xob conductivity, xws li insulator mus rau conductor.

Plaub yam khoom ntawm semiconductors.

Kev tshawb pom ntawm cov khoom siv hluav taws xob tuaj yeem tshawb pom rov qab mus txog 1833, thaum Faraday, tus kws tshawb fawb Askiv, thiab leej txiv ntawm electronics, yog thawj zaug pom tias qhov tsis kam ntawm cov nyiaj sulfide sib txawv nrog qhov kub ntawm qhov sib txawv ntawm cov hlau zoo tib yam, uas yog thawj zaug. nrhiav pom ntawm lub semiconductor phenomenon.

Tab sis cov ntsiab lus ntawm cov khoom ntawm semiconductors tsis tiav kom txog rau thaum Lub Kaum Ob Hlis 1947 los ntawm Bell Laboratories.

Qhov kub nce, thiab tsis kam ntog: qhov tsis kam ntawm ib qho semiconductor txo qis thaum kub nce, tab sis, feem ntau, cov hlau tsis kam nce nrog qhov kub thiab txias.

Cov nyhuv photovoltaic: qhov sib txuas tsim los ntawm kev sib cuag ntawm ib qho khoom siv hluav taws xob thiab cov hluav taws xob tsim hluav taws xob thaum raug lub teeb.

Cov nyhuv photoconductive: cov conductivity ntawm ib tug semiconductor nce nyob rau hauv lub xub ntiag ntawm lub teeb.

Rectification nyhuv: lub conductivity ntawm ib tug semiconductor yog directional thiab muaj feem xyuam rau cov kev taw qhia ntawm hluav taws xob teb thov.Ntxiv qhov hluav taws xob zoo rau qhov kawg ntawm lub semiconductor thiab nws yog conductive;Yog hais tias qhov voltage polarity yog thim rov qab, nws tsis conducive.
