Uhlobo lwe-MOSFET nokwakhiwa

Isikhathi Sokuthumela: May-31-2024

Kanye nokuthuthukiswa okuqhubekayo kwesayensi nobuchwepheshe, onjiniyela bokuklama imishini kagesi kumele baqhubeke nokulandela izinyathelo zesayensi nobuchwepheshe obuhlakaniphile, ukukhetha izingxenye ze-elekthronikhi ezifaneleka kakhulu zezimpahla, ukuze benze izimpahla zihambisane kakhulu nezidingo ze-elekthronikhi. izikhathi. Lapho iI-MOSFET yizingxenye eziyisisekelo zokwenziwa kwemishini kagesi, ngakho-ke ufuna ukukhetha i-MOSFET efanele kubaluleke kakhulu ukuze ubambe izici zayo nezinhlobonhlobo zezinkomba.

Endleleni yokukhetha imodeli ye-MOSFET, kusukela esakhiweni sefomu (uhlobo lwe-N noma uhlobo lwe-P), i-voltage esebenzayo, ukusebenza kokushintshwa kwamandla, izinto zokupakisha kanye nemikhiqizo yayo eyaziwayo, ukubhekana nokusetshenziswa kwemikhiqizo ehlukene, izidingo. zilandelwa ezehlukene, empeleni sizochaza okulandelayoUkupakishwa kwe-MOSFET.

Ngemva kweI-MOSFET I-chip yenziwe, kufanele ifakwe ngaphambi kokuthi isetshenziswe. Ukulibeka ngembaba, ukupakisha kuwukwengeza ikesi le-chip ye-MOSFET, leli cala linendawo yokusekela, ukugcinwa, umphumela wokupholisa, futhi ngasikhathi sinye futhi linikeza ukuvikeleka kokumiswa kwe-chip nokuvikela, izingxenye ze-MOSFET ezilula kanye nezinye izakhi zokwakha. isekethe enemininingwane yokunikezwa kwamandla.

Iphakheji ye-MOSFET yamandla okukhiphayo ifakiwe futhi ihlola i-surface mount izigaba ezimbili. Ukufakwa iphinikhodi ye-MOSFET ngokusebenzisa i-PCB ekhweza izimbobo e-soldering ye-PCB. I-Surface Mount izikhonkwane ze-MOSFET kanye nendlela yokukhishwa kokushisa yokunamathisela endaweni engaphezulu yesendlalelo sokushisela se-PCB.

I-Chip Raw materials, ukucubungula ubuchwepheshe kuyisici esibalulekile sokusebenza kanye nekhwalithi yama-MOSFETs, ukubaluleka kokuthuthukisa ukusebenza kwabakhiqizi bokukhiqiza be-MOSFET kuzoba kusakhiwo esiyinhloko se-chip, ukuminyana okuhlobene kanye nezinga lokucubungula ubuchwepheshe ukuze kwenziwe ngcono. , futhi lokhu kuthuthukiswa kobuchwepheshe kuzotshalwa ngemali ebiza kakhulu. Ubuchwepheshe bokupakisha buzoba nomthelela oqondile ekusebenzeni okuhlukahlukene kwe-chip kanye nekhwalithi, ubuso be-chip efanayo budinga ukupakishwa ngendlela ehlukile, ukwenza kanjalo kungathuthukisa ukusebenza kwe-chip.
