1.Vim li cas ho tsis pom zoo kom siv cov khaub thuas txias -rolled coils?
Kev huv huv thiab tso pa tawm cov teeb meem:
Chip ntim (tshwj xeeb tshaj yog pem hauv ntej-kawg thiab kev sim) yuav tsum muaj ib puag ncig huv si ultra-. Txawm tias qhov tsawg tshaj plaws ntawm cov pa paug tuaj yeem ua rau nti tsis ua haujlwm.
Tej yam txias-rolled steel yog oxidation thiab xeb. Txawm tias plating, ntev - lub sij hawm kev sib txhuam los yog thermal cycling tuaj yeem tsim micron - cov hlau me me thiab hmoov av.
Nyob rau hauv lub tshuab nqus tsev los yog siab - qhov kub thiab txias, impurities thiab adsorbed gases nyob rau hauv cov khoom yuav raug tso tawm, paug cov nti thiab kab noj hniav. Txias-rolled steel muaj cov roj tso tawm siab, ua tsis tau raws li qhov yuav tsum tau ua kom huv.
Magnetic Properties:
Carbon steel yog cov khoom siv ferromagnetic. Thaum lub sij hawm ntim ntim thiab kuaj, ib qho kev cuam tshuam sib nqus tuaj yeem cuam tshuam qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob (xws li lub cim xeeb thiab cov sensors) lossis cuam tshuam rau qhov chaw ntawm caj npab robotic.
Ib puag ncig uas tsis yog- sib nqus yog tus qauv hauv kev cob qhia semiconductor niaj hnub; yog li ntawd, tsis yog- cov khoom sib nqus yog nyiam rau cov khoom siv.
2.Nws yuav raug txiav txim siab lossis siv li cas?
Tsis yog- cov khoom tseem ceeb ntawm lub fixture: Piv txwv li, lub thav duab sab nrauv, lub hauv paus kev txhawb nqa, thiab lub plhaub sab nraud ntawm tag nrho cov khoom siv sib tw-cov khoom uas tsis ncaj qha rau cov nti, tsis txhob nkag mus rau qhov chaw huv, thiab tsis tas yuav tsum tau ua kom zoo sib xws - tuaj yeem ua tau los ntawm kev siv qis dua -cov nqi steel -rolled.
Tsawg-qhov kawg lossis cov khoom ntim tsis sib xws: Rau qee qhov qis-kawg cov khoom siv semiconductor nrog cov kev cai qis thiab tsis hnov tsw rau tus nqi thiab kev sib kis (xws li qee cov diodes thiab transistors), cov khoom yuav tsum tau rau lawv cov khoom ntim yuav tau so.
Ib ntus lossis R&D fixtures: Nyob rau theem pib ntawm R&D, txhawm rau txheeb xyuas tus qauv sai sai, cov qauv kev sib tw yuav raug tsim los siv cov khoom siv tau yooj yim thiab cov khoom siv tau yooj yim (xws li txias -khoov hlau).
3.Dab tsi yog cov ntaub ntawv tseem ceeb rau chip ntim fixtures?
Stainless hlau (tshwj xeeb tshaj yog austenitic stainless hlau xws li 304 thiab 316):
Qhov zoo: Kev tiv thaiv corrosion zoo heev, tsis yog -sib nqus (cov qauv austenitic), tus nqi qis qis (tom qab polishing), lub zog siab, yooj yim los ntxuav.
Daim ntaub ntawv: Test socket vaj tse, precision caij nplooj ntoos hlav probes, sorting tshuab hoppers, tiv tauj Cheebtsam, thiab lwm yam. Ib qho ntawm feem ntau siv hlau cov ntaub ntawv.
Invar / Invar Alloy:
Qhov zoo: Ultra- qis coefficient ntawm thermal expansion (~ 1.2 ppm / degree), zoo kawg nkaus txuam nrog silicon. Qhov no yog nws irreplaceable core kom zoo dua.
Cov ntawv thov: Cov ntawv thov uas xav tau kev sib tw thermal nthuav dav heev, xws li multi-chip module ntim substrates, siab -precision optical calibration platforms, hlawv-hauv qhov ntsuas qhov (socket substrates), thiab lwm yam. kim.
Aluminium Alloy (xws li 6061 thiab 7075):
Qhov zoo: Lub teeb yuag, yooj yim rau kev ua, thermal conductivity zoo, tus nqi nruab nrab, tsis yog -magnetic.
Daim ntaub ntawv: Cov khoom siv loj loj, cov dab dej kub hauv lub hauv paus, sorting tshuab turrets, thiab lwm yam khoom siv. Hard anodizing feem ntau yog ua los txhim kho qhov tawv tawv thiab hnav tsis kam.
4.Dab tsi yog qhov zoo ntawm kev siv engineering yas?
Qhov zoo: Rwb thaiv tsev, tsis yog- sib nqus, lub teeb yuag, hnav- tiv taus, tus kheej- lubricating, thiab nrog tswj tau cov pa tso tawm.
Daim ntaub ntawv: Insulating gaskets, hnav-cov lus qhia resistant, tsis yog-cov khoom siv hlau, thiab lwm yam.
5.Dab tsi yog qhov zoo ntawm kev siv titanium alloys?
Qhov zoo: Lub zog siab, lub teeb yuag, zoo heev corrosion kuj, thiab biocompatibility (tsim rau ib puag ncig tshwj xeeb).
Daim ntaub ntawv: Cov ntawv thov tshwj xeeb xav tau lub zog siab heev thiab kev tiv thaiv corrosion, tab sis ntawm tus nqi siab.
