Musiyano uripoPCBrakadhindwa redunhu bhodhi uye rakasanganiswa redunhu:
1. Maseketi akabatanidzwa anowanzo reva kubatanidzwa kwechipisi, senge chamhembe bhiriji chip pabhodhi reamai, uye mukati meCPU, ese anonzi maseketi akabatanidzwa, uye zita rekutanga rinonziwo mabhuroki akabatanidzwa.Dunhu rakadhindwa rinoreva mapuranga edunhu atinowanzoona, pamwe nekudhinda uye soldering machipisi pabhodhi redunhu.
2. Iyo yakabatanidzwa yedunhu (IC) inosungirirwa paPCB board;iyo PCB board ndiyo inotakura yedunhu rakasanganiswa (IC).Bhodhi rePCB ibhodhi redunhu rakadhindwa (Printed circuit board, PCB).Mabhodhi edunhu akadhindwa anowanikwa munenge mune zvese zvigadzirwa zvemagetsi.Kana pane zvikamu zvemagetsi mune chimwe chigadzirwa, mabhodhi edunhu akadhindwa anoiswa paPCB dzehukuru hwakasiyana.Mukuwedzera pakugadzirisa zvikamu zviduku zvakasiyana-siyana, basa guru rebhodhi redunhu rakadhindwa nderekubatanidza nemagetsi zvikamu zvakasiyana-siyana pamusoro.
3. Kuzvitaura zviri nyore, dunhu rakabatanidzwa rinobatanidza dhipatimendi rechinangwa-chinangwa mu chip.Zvakakwana.Kana ichinge yakuvadzwa mukati, iyo chip ichakuvadzwa zvakare, uye iyo PCB inogona solder zvikamu zvega.Kana yakaputsika, inogona kutsiviwa.element.
PCB ibhodhi redunhu rakadhindwa, rinodaidzwa sebhodhi rakadhindwa, uye chimwe chezvinhu zvakakosha zveindasitiri yemagetsi.Anenge marudzi ese emidziyo yemagetsi, kubva pawachi dzemagetsi uye macalculator kusvika kumakomputa, midziyo yemagetsi yekukurukurirana, uye masisitimu ezvombo zvehondo, chero paine zvinhu zvemagetsi zvakaita semaseketi akabatanidzwa, kuitira kuti magetsi abatanidzwe pakati pezvikamu zvakasiyana, akadhindwa dunhu. mapuranga anofanira kushandiswa.ndiro.
Iyo yakadhindwa yedunhu bhodhi inoumbwa ne insulating base plate, waya dzekubatanidza uye mapadhi ekuunganidza uye welding zvemagetsi zvinhu, uye ine mabasa maviri emutsetse we conductive uye insulating base plate.Inogona kutsiva wiring yakaoma uye kuona kubatana kwemagetsi pakati pezvikamu zvedunhu, izvo zvisingarerutsi kuungana uye welding yezvigadzirwa zvemagetsi, inoderedza kuwanda kwewaya munzira dzechinyakare, uye inoderedza zvakanyanya kusimba kwevashandi;inoderedzawo saizi yemuchina wese.Vhoriyamu, kuderedza mutengo wechigadzirwa, kuvandudza kunaka uye kuvimbika kwemidziyo yemagetsi.
Dunhu rakasanganiswa chinhu chidiki chemagetsi kana chikamu.Uchishandisa imwe nzira, ma transistors, resistors, capacitors, inductors uye zvimwe zvikamu zvinodiwa mudunhu zvakabatana, uye zvinogadzirwa padiki kana akati wandei madiki semiconductor wafers kana dielectric substrates, zvobva zvaiswa muchubhu., uye ive microstructure ine mabasa anodiwa edunhu;zvinhu zvose zviri mukati maro zvakabatanidzwa, zvichiita kuti zvikamu zvemagetsi zvive danho guru kune miniaturization, kushandiswa kwesimba shoma, njere uye kuvimbika kwakanyanya.Inomiririrwa nebhii “IC” mudunhu.Vagadziri vedunhu rakabatanidzwa ndiJack Kilby (germanium (Ge)-based integrated circuits) uye Robert Noyce (silicon (Si)-based integrated circuits).Mazhinji emazuva ano semiconductor indasitiri anoshandisa silicon-based integrated circuits.
