Chii chinonzi thermal expansion coefficient yegranite bed?Izvi zvakakosha sei kune semiconductor zvishandiso?

Granite isarudzo yakakurumbira yemubhedha wemidziyo yesemiconductor nekuda kwekugadzikana kwayo kwekupisa uye kusimba kwemagetsi.Thermal expansion coefficient (TEC) yegranite chinhu chakakosha chemuviri chinotaridza kukodzera kwayo kushandiswa muzvikumbiro izvi.

Thermal yekuwedzera coefficient yegraniti inenge iri pakati pe4.5 - 6.5 x 10^-6/K.Izvi zvinoreva kuti padhigirii rega rega Celsius kuwedzera kwekushisa, mubhedha wegranite uchawedzera nehuwandu uhu.Kunyange izvi zvingaite senge shanduko diki, zvinogona kukonzera matambudziko akakura mumidziyo yesemiconductor kana isina kuverengerwa zvakanaka.

Semiconductor zvishandiso zvinonyanya kufunga nezvekuchinja kwekushisa, uye chero kudiki kusiyanisa kwekushisa kunogona kukanganisa kuita kwavo.Naizvozvo, zvakakosha kuti TEC yezvinhu zvinoshandiswa mumidziyo iyi yakaderera uye inofanotaurwa.Granite yakaderera TEC inobvumira kugadzikana uye kunoenderana kupisa kupisa kubva pachigadzirwa, kuve nechokwadi chekuti tembiricha inoramba iri mukati meiyo yaunoda.Izvi zvakakosha nekuti kupisa kwakanyanya kunogona kukuvadza semiconductor zvinhu uye kupfupisa hupenyu hwayo.

Chimwe chinhu chinoita kuti granite ive chinhu chinoyevedza pamubhedha wemichina yesemiconductor isimba rayo remuchina.Kugona kwemubhedha wegranite kutsungirira kuwanda kwekushushikana uye kuramba wakatsiga kwakakosha nekuti michina yesemiconductor inowanzoiswa pasi pekudengenyeka kwemuviri uye kuvhunduka.Kuwedzera kwakasiyana-siyana uye kuputika kwezvinhu nekuda kwekuchinja kwekushisa kunogona kukonzera kushushikana mukati memudziyo, uye kugona kwegranite kuchengetedza chimiro chayo pasi pemamiriro aya kunoderedza njodzi yekukuvara nekutadza.

Mukupedzisa, thermal yekuwedzera coefficient yegranite bed inoita basa rakakosha mukuita kwesemiconductor zvishandiso.Nekusarudza chinhu chine yakaderera TEC, senge granite, vagadziri vezvigadzirwa zvekugadzira chip vanogona kuve nekugadzikana kwekushanda kwemafuta uye kushanda kwakavimbika kwemidziyo iyi.Ichi ndicho chikonzero granite inoshandiswa zvakanyanya semidziyo yemubhedha muindasitiri yesemiconductor, uye kukosha kwayo hakugone kuwedzeredzwa kana zvasvika pakuvimbisa kunaka uye hupenyu hurefu hwemidziyo iyi.
