Amakamelo okuhlanza ama-semiconductor asebenza njengezithwali ezivaliwe eziyinhloko zokuqopha, ukufakwa kwe-PVD kanye nezinqubo zokufakelwa kwama-ion, ukukhetha okungafanele kwe-alloy kubangela ukuphuma okuphezulu kwegesi, ukuphambuka kwesakhiwo noma ukuvuza kwe-vacuum, okunciphisa ngqo isivuno sokukhiqizwa kwe-wafer. Zombili i-5052 H32 kanye ne-5083 H321 zingeze-Al-Mg engalapheki ngokushisa.amazinga e-aluminium akhiwe,kodwa ukwakheka okuhlukahlukene kwe-magnesium kanye ne-manganese kuhlukanisa ngokuphelele izimo zazo ze-semiconductor cavity ezisebenzayo.

I-Chemistry ibeka umngcele wokusebenza. I-5052 iqukethe i-2.2~2.8 wt% Mg enesici se-Mn esingaphansi kuka-0.1%, kuyilapho i-5083 ithuthukisa okuqukethwe kwe-Mg ku-4.0~4.9% kanye ne-0.4~1.0% manganese ukuze kuhlungwe okusanhlamvu kanye nokuqinisa isixazululo esiqinile. Lesi sikhala sokwakheka sinikeza amandla okuqina aphezulu angu-38~42% ku-5083 (310~320MPa vs 215~230MPa ka-5052), okwenza uhlelo lwayo lokuqala lokuklama izindlu ze-semiconductor.

I-5052 ibusa amakamelo okudlulisa amancane, ayinkimbinkimbi kanye nezindawo ezincane zokuvala umthwalo emishinini ye-semiconductor ephakathi nendawo. Ukwakheka kwayo okubandayo okuphezulu kanye nokuguquguquka kwenza kube lula ukusebenza kwe-multi-axis CNC deep pocket machining, ukugaya isiteshi sokupholisa okuyinkimbinkimbi kanye nokwakheka kwe-flange encane ehlanganisiwe ngaphandle kokuguqulwa kwe-springback. I-alloy inezinga eliphansi lokukhipha igesi elilawulwayo elingaphansi kuka-10⁻⁸ Torr·L/(s·cm²) ngemva kokupholisha ngokunemba, ihambisana nezindinganiso eziyisisekelo zokuvala i-vacuum ephezulu (UHV) yezinhlobo ezincane zenqubo ye-batch. Ukusebenza kahle kwezindleko kungenye into evelele: ukusetshenziswa kwezinto zokusetshenziswa zokusika okungu-5052 okungu-12~15% uma kuqhathaniswa no-5083, okulungele ama-casing ajwayelekile e-semiconductor peripheral akhiqizwa ngobuningi be-OEM kanye nezindawo zokufaka inzwa ezisizayo. Ifektri yethu ifinyelela ukuvala okuphezulu kanyeukuqedela ukukhanda amashidi angu-5052, imigoqo eqinile namashubhu e-aluminium angenamthungo anokubekezelelana okulinganayo okungu-±0.003mm ngokusebenzisa izikhungo zomshini ze-CNC ezinama-axis amahlanu.

Ukushintshela emakamelweni enqubo aqinile, bese i-5083 iba yinto engenakuphikwa. Ukuqina kwayo okuphezulu komshini kumelana nokuguquguquka kwengcindezi yokuguquguquka kwe-vacuum kanye nokuqhekeka okuphindaphindiwe kokujikeleza kokushisa ngaphansi kwezimo zokusebenza ezishintshashintshayo zokushisa okuphezulu ngaphakathi kwemigodi yokufaka. I-H321 tempered 5083 ifaka ukumelana kwe-optimized stress corrosion cracking (SCC) ngokumelene negesi yenqubo ebolayo esekelwe ku-halogen, okubalulekile emishinini ethuthukisiwe ye-etch evezwe emoyeni we-plasma oqukethe i-fluorine. Ukuqina okuphezulu kwe-cryogenic kuhambisana kakhulu namakamelo enqubo ye-semiconductor yokushisa okuphansi asebenza endaweni yokusebenza engaphansi kwe-zero, egwema ukwehluleka kwe-brittle crack ngaphansi kokushaqeka kokushisa.

Amandla ethu okukhiqiza ngaphakathi asekela imishini eyenziwe ngokwezifiso yazo zombili izinhlobo ze-alloy. Sihlome nge-workshop ehlanzekile ye-Class 10,000, i-helium mass spectrometer leak detector kanye nomugqa wokuhlanza we-ultrasonic ozenzakalelayo, sifeza isevisi eyodwa-stop kusukela ekusikeni kwe-aluminium slab, i-precision CNC machining, i-inert-gas TIG welding kuya ekuqedeni okuphezulu kwe-ultra fine surface yezingxenye ze-semiconductor cavity. Umkhiqizo wanyanga zonke ufinyelela ngaphezu kwamathani angu-35 ezingxenye eziqediwe ze-5052/5083 ezenziwe ngomshini, ezimboza ipuleti le-aluminium elenziwe ngokwezifiso, ibha ye-aluminium eqinile kanye ne-hollow aluminium tube raw stock supply kanye nokwakhiwa kwegumbi eliqediwe.

Kumakhasimende adidekile ngokukhetha amamaki:khetha u-5052 ukuze uthole ukukhanya okulula, imigodi emincane eyinkimbinkimbi ezwela izindleko. Khetha i-5083 ukuze uthole amakamelo enqubo enkulu, umthwalo omningi, nendawo egqwalisayo. Ithimba lethu lobunjiniyela linikeza ukubonisana kwamahhala kwesakhiwo se-FEA kanye nokukhethwa kwezinto ukuze kuthuthukiswe isabelomali sakho sokuthenga i-semiconductor enclosure kanye nokuzinza kwemishini yesikhathi eside.
