Kwimveliso ye-semiconductor, ungcoliseko lulinganiswa kwiindawo ngesigidi kunye nobukhulu be-particle kwi-microns. Iyoni enye elahlekileyo, ikhompawundi eguquguqukayo yezinto eziphilayo, okanye isuntswana le-microscopic lingalahla yonke ibhetshi ye-wafer- exabisa amakhulu amawaka eedola.
I-PTFE iteyiphu yobushushu obuphezulu , kunye nokunganyangeki kobushushu, ukunganyanzeli kweekhemikhali, indawo engabambekiyo, kunye neempawu zombane, idlala indima ebalulekileyo kule meko. Kodwa hayi nje nayiphi na iteyiphu yePTFE eya kwenza. Iiteyiphu zodidi lweSemiconductor kufuneka zihlangabezane nemigangatho yococeko ephezulu kakhulu engaphezulu lee kwiiteyiphu zemizi-mveliso ngokubanzi.
I-Aokai PTFE yenza iteyiphu yePTFE ngokukodwa kwizicelo zesemiconductor. Esi sikhokelo sibandakanya iindawo ezintathu ezingundoqo zesicelo - ukusetyenzwa kwenqanaba le-wafer, ukupakishwa kunye nokuvavanya, kunye nokugcinwa kwezixhobo - kunye neemfuno ezingqongqo zococeko ezisebenza kumntu ngamnye.
Iimeko zeSicelo esiPhambili-Ukukhusela iMicimbi yeXabiso eliPhezulu

2. Iinkqubo zokupakishwa kunye nokuvavanya
Isakhelo esikhokelayo / ukulungiswa kwe-substrate: Ukumiswa kobushushu ngexesha lokudibanisa ucingo, ukudibanisa ukufa, kunye ne-plastic encapsulation - ibamba amacandelo angaguquki kumaqondo aphezulu.
Ukugquma i-wave soldering kunye ne-reflow soldering: Ikhusela iminwe yegolide kunye neendawo zoqhagamshelwano kwii-PCBs ekungcoleni kwee-solder ngexesha leenkqubo zokushisa eziphezulu.
I-high-temperature tape carrier sheets: Abathwali be-Flexible ukukhusela i-substrates encinci kwimigca yokuvelisa ngaphandle kokukhupha amaqhekeza okanye iintsalela.
3. Ukugcinwa kwezixhobo kunye nokusetyenziswa kokuncedisa
I-Anti-static roller wrapping: I-Clads yokuthutha i-roller ukubonelela ngobushushu obuphezulu, i-non-stick, kunye ne-static-dissipative contact surfaces - ikhusela umonakalo we-wafer kwi-friction kunye nokukhutshwa okumileyo.
Igumbi elicocekileyo lokumakishwa kunye nokugcinwa kwethutyana: Ukufaka iilebhile, ukulungiswa kwentambo okwethutyana, kunye nokulungiswa okuncinci ngaphandle kokwazisa ungcoliseko.
IiMfuno zokuCoceka okuphezulu kakhulu-iMigangatho engaxoxiswanga
Le yimigangatho eyahlula i-semiconductor-grade PTFE tape ukusuka kwiteyiphu yenjongo jikelele. Ukungathotyelwa kwemigaqo kunokukhokelela ekuchithweni kwebhetshi ngokupheleleyo. I-Aokai PTFE iqinisekisa zonke ezi parameters kwiiteyiphu zethu ze-semiconductor-grade.
