Kufunika kwa mapaipi a gasi oyera kwambiri kwa ma semiconductors

As semiconductorNdipo ukadaulo wamagetsi ang'onoang'ono ukukula kuti ugwire bwino ntchito komanso uphatikizidwe bwino, zofunikira kwambiri zimayikidwa pa kuyera kwa mpweya wapadera wamagetsi. Ukadaulo wa mapaipi a mpweya woyera kwambiri ndi gawo lofunikira la dongosolo loperekera mpweya woyera kwambiri. Ndi ukadaulo wofunikira kwambiri woperekera mpweya woyera kwambiri womwe umakwaniritsa zofunikira kumalo ogwiritsira ntchito mpweya uku ukupitirizabe kukhala ndi khalidwe loyenerera.

Ukadaulo wa mapaipi oyeretsedwa kwambiri umaphatikizapo kapangidwe kolondola ka dongosololi, kusankha zida zolumikizira mapaipi ndi zinthu zina zothandizira, kumanga ndi kukhazikitsa ndi kuyesa.

01 Lingaliro la mapaipi opatsira mpweya

Mpweya wonse woyera kwambiri komanso woyeretsa kwambiri uyenera kunyamulidwa kupita kumalo osungiramo mpweya kudzera m'mapaipi. Kuti mukwaniritse zofunikira pa khalidwe la mpweya, pamene chizindikiro cha kutumiza mpweya kunja chikutsimikizika, ndikofunikira kwambiri kulabadira kusankha zinthu ndi khalidwe la makina omangira mapaipi. Kuwonjezera pa kulondola kwa zipangizo zopangira kapena kuyeretsa mpweya, zimakhudzidwa kwambiri ndi zinthu zambiri za makina opaira. Chifukwa chake, kusankha mapaipi kuyenera kutsatira mfundo zoyenera za makampani oyeretsa ndikuwonetsa zinthu za mapaipiwo pazithunzi.

02 Kufunika kwa mapaipi oyera kwambiri pakunyamula gasi

Kufunika kwa mapaipi oyera kwambiri pakunyamula mpweya woyera kwambiri. Panthawi yosungunula chitsulo chosapanga dzimbiri, tani iliyonse imatha kuyamwa pafupifupi 200g ya mpweya. Chitsulo chosapanga dzimbiri chikakonzedwa, sikuti zinthu zosiyanasiyana zoipitsa zimangoikidwa pamwamba pake, komanso mpweya wina umalowa mu lattice yake yachitsulo. Mpweya ukadutsa mu payipi, gawo la mpweya lomwe limayamwa ndi chitsulocho lidzalowanso mu mpweya ndikuipitsa mpweya woyera.

Mpweya ukatuluka mu chitolirocho, chitolirocho chimapanga kulowetsedwa kwa mpweya womwe umadutsa. Mpweyawo ukasiya kutuluka, mpweya womwe umalowetsedwa ndi chitolirocho umapanga kusanthula kochepetsa kuthamanga, ndipo mpweya wowunikidwawo umalowanso mu mpweya woyera womwe uli mu chitolirocho ngati chidetso.

Nthawi yomweyo, njira yothira madzi ndi kusanthula imapangitsa kuti chitsulo chomwe chili mkati mwa chitoliro chipange ufa winawake. Fumbi lachitsuloli limaipitsanso mpweya woyera womwe uli mu chitolirocho. Khalidwe la chitolirochi ndilofunika kwambiri. Pofuna kutsimikizira kuti mpweya wonyamulidwa ndi woyera, sikuti pamafunika kuti mkati mwa chitolirocho mukhale wosalala kwambiri, komanso kuti ukhale wotetezeka kwambiri.

Mpweya ukakhala ndi mphamvu zowononga, mapaipi achitsulo chosapanga dzimbiri ayenera kugwiritsidwa ntchito popopera mapaipi. Kupanda kutero, madontho a dzimbiri adzawonekera mkati mwa chitoliro chifukwa cha dzimbiri. Pa milandu yoopsa, zidutswa zazikulu zachitsulo zidzatuluka kapena kuboola, motero kuipitsa mpweya woyera womwe ukunyamulidwa.

03 Zinthu zogwirira ntchito pa chitoliro

Kusankha zinthu za chitolirocho kuyenera kusankhidwa malinga ndi zosowa za chitolirocho. Ubwino wa chitolirocho nthawi zambiri umayesedwa malinga ndi kuuma kwa pamwamba pa chitolirocho. Kuuma kwake kukakhala kochepa, kumakhala kosavuta kunyamula tinthu tating'onoting'ono. Kawirikawiri zimagawidwa m'mitundu itatu:

Chimodzi ndiChitoliro cha EP grade 316L, yomwe yapukutidwa ndi electrolytically (Electro-Polish). Ndi yolimba ndi dzimbiri ndipo ili ndi kuuma kochepa pamwamba. Rmax (kutalika kwa pamwamba mpaka chigwa) ndi pafupifupi 0.3μm kapena kuchepera. Ili ndi kusalala kwambiri ndipo sikophweka kupanga mafunde ang'onoang'ono a eddy. Chotsani tinthu tating'onoting'ono tomwe taipitsidwa. Mpweya woyankhira womwe umagwiritsidwa ntchito pochita izi uyenera kuyikidwa paipi pamlingo uwu.

Chimodzi ndiGiredi ya BA 316Lchitoliro, chomwe chakonzedwa ndi Bright Anneal ndipo nthawi zambiri chimagwiritsidwa ntchito pa mpweya womwe umakhudzana ndi chip koma sugwira nawo ntchito, monga GN2 ndi CDA. Chimodzi ndi chitoliro cha AP (Annealing & Picking), chomwe sichimakonzedwa mwapadera ndipo nthawi zambiri chimagwiritsidwa ntchito pa mapaipi awiri akunja omwe sagwiritsidwa ntchito ngati mizere yoperekera mpweya.

04 Kumanga mapaipi

Kukonza pakamwa pa chitoliro ndi chimodzi mwa mfundo zofunika kwambiri pa ukadaulo womanga uwu. Kudula ndi kukonza mapaipi kumachitika pamalo oyera, ndipo nthawi yomweyo, zimatsimikiziridwa kuti palibe zizindikiro kapena kuwonongeka koopsa pamwamba pa payipi musanadule. Kukonzekera kutsuka kwa nayitrogeni mu payipi kuyenera kuchitika musanatsegule payipi. Mwachidule, kuwotcherera kumagwiritsidwa ntchito kulumikiza mapaipi opatsira ndi kugawa gasi oyera kwambiri komanso oyera kwambiri okhala ndi madzi ambiri, koma kuwotcherera mwachindunji sikuloledwa. Mapaipi olumikizira ayenera kugwiritsidwa ntchito, ndipo zinthu zomwe zimagwiritsidwa ntchito pa chitoliro ziyenera kusasinthika kapangidwe kake panthawi yowotcherera. Ngati zinthu zomwe zili ndi kaboni wambiri zawotcherera, mpweya wolowera m'gawo lowotcherera udzapangitsa kuti mpweya mkati ndi kunja kwa chitolirocho ulowerere wina ndi mnzake, kuwononga chiyero, kuuma ndi ukhondo wa mpweya wonyamula, zomwe zingayambitse zotsatirapo zoyipa ndikukhudza mtundu wa kupanga.

Mwachidule, pa mapaipi a mpweya woyeretsedwa kwambiri ndi mapaipi apadera otumizira mpweya, chitoliro chachitsulo chosapanga dzimbiri choyeretsedwa bwino chiyenera kugwiritsidwa ntchito, zomwe zimapangitsa kuti mapaipi a mpweya woyeretsedwa kwambiri (kuphatikizapo mapaipi, zolumikizira mapaipi, ma valve, VMB, VMP) akhale ndi ntchito yofunika kwambiri pakugawa mpweya woyeretsedwa kwambiri.
