Umphakeli Wezingxenye Ze-elekthronikhi Umjikelezo Ohlanganisiwe LM2904 ADS8341E/2K5 OPT3001IDNPRQ1 TPS79101DBVRG4Q1 chip

1.Yini i-bonding (chip bonding kanye ne-bonding)

i-bonding iyindlela yokuhlanganisa inqubo yokukhiqiza i-chip, ngokuvamile esetshenziselwa ukuxhuma ukujikeleza kwangaphakathi kwe-chip nezikhonkwane zephakeji ngocingo lwegolide ngaphambi kokupakisha, futhi ngokuvamile ngemva kokuhlanganisa (okungukuthi ngemva kokuba i-circuitry ixhunywe kumaphini) i-chip ifakwe ijeli elimnyama ngenkathi isebenzisa ubuchwepheshe obuphambili bokupakisha bangaphandle i-COB (ChipOnBoard), le nqubo kufanele ihlole i-epitaxial wafer efakwe ebhodini lesifunda elikhethekile, bese kuba i-epitaxial wafer circuit exhunywe ebhodini lesifunda ngocingo lwegolide, bese liyancibilika. ngomsebenzi okhethekile wokuvikela wezinto eziphilayo ezimbozwe ama-epitaxial wafers ukuqedela i-post-encapsulation ye-chip.

2.Iyini i-semiconductor?

Ake siqale ngokuthi iyini i-semiconductor.Ngokombono wezinto ezibonakalayo: i-semiconductor iyimpahla enezici zokuqhuba phakathi kwalezo zomqhubi kanye ne-insulator ekamelweni lokushisa.Njengokuphila kwansuku zonke, izintambo zethusi ne-aluminium zingamakhondatha, kuyilapho irabha nokunye okunjalo kuyizivikeli.Ngokuphathelene ne-electrical conductivity: i-semiconductor iyimpahla elawulwayo kagesi, kusukela ku-insulator kuya ku-conductor.

Izici ezine zama-semiconductors.

Ukutholakala kwama-semiconductors kungalandelelwa emuva kuze kube ngo-1833, lapho uFaraday, usosayensi waseBrithani, noyise wezogesi, engowokuqala ukuthola ukuthi ukumelana nesiliva sulfide kwakuhlukahluka ngezinga lokushisa elihlukile kunelensimbi evamile, okwakungeyokuqala. ukutholakala kwe-semiconductor phenomenon.

Kodwa isifinyezo sezakhiwo zama-semiconductors asizange siqedwe kuze kube nguDisemba 1947 yiBell Laboratories.

Izinga lokushisa liyakhuphuka, futhi ukumelana kwehla: ukumelana kwe-semiconductor kunciphisa njengoba izinga lokushisa likhuphuka, kodwa, ngokuvamile, ukumelana kwensimbi kukhula ngokushisa.

Umphumela we-Photovoltaic: ukuhlangana okwakhiwa ngokuthintana phakathi kwe-semiconductor ne-electrolyte kukhiqiza i-voltage lapho kuvezwe ekukhanyeni.

Umphumela we-Photoconductive: ukuqhutshwa kwe-semiconductor kuyanda lapho kukhona ukukhanya.

Umphumela wokulungisa: ukuqhutshwa kwe-semiconductor kuyaqondisa futhi kuhlobene nesiqondiso senkambu kagesi esetshenzisiwe.Faka i-voltage eqondile ekugcineni kwe-semiconductor futhi iyaqhuba;uma i-voltage polarity ihlehlisiwe, ayihambisani.
