E nder weeyo suudu ina ñaawee e dimensiyonji, e ɓuuɓri e ɓuuɓri yeeso-siilngo. E nder njuɓɓudi weeyo, sifaaji ɗii ina mbayla haa laaɓi : njaaweeki yaltugol gaas, ɓuuɓol dow, heddiiɓe e ɓulli wumɓe, e riis galvanik ɗo njamndiiji ɗi nanndaani memi. Hay heen gootal winndaaka e natal ngal.

Feccere e nder Vacuum ina ñaawee no feewi

E nder weeyo suudu aluminium ina ƴeewtee e dimensiyonji, e ɓuuɓri e ɓuuɓri yeeso-siilngo. E nder system vacuum, set goɗɗo ina huutoree : njaaweeki yaltugol huunde, adsorption surface, heddiiɓe e ɓulli wumɓe, e corrosion galvanique ɗo njamndiiji ɗi nanndaani kawrata. Hay heen gootal feeñataa e natal ngal, eɓe kawra e maɓɓe so tawii suudu nduu ina pompa les ngam tarde.

Gaasuuji yaltuɗi ɗii ɓuri arde ko e ndiyam e geɗe nguurndam gonɗe e dow leydi, ɓeyda heen hidrogen ɓuuɓɗo e nder huunde ndee. Anodising ina ɓeyda wertallo leydi, ina wayla oksidaa oo e ɓuuɓri ; coolant nanngaaɗo e ɓuuɓri wumre ina jokki e yaltinde fotde waktuuji. Wonande geɗe laaɓtuɗe peewnaaɗe e kaɓirɗe semmbeeji, ko adii fof ko ɗaɓɓaande wonaa laaɓal kono ko laaɓal e teskaade.

Outgassing: Haalaaji gonɗi e dow leydi ɓuri alloy

E dow oon 6061 aluminium gooto, ɓuuɓɗi, ɓuuɓɗi kemikal e anodiseeji tiiɗɗi ina ceerti e njaaweeki yaltugol gaasuuji e doggol mawneeki. Anodising ko ɓoornaade e ɓuuɓde, kono e les vacuum toowɗo ina waɗa no sponge nii. Ɗo geɗe yaltugol gaasuuji, polindagol kemikal walla elektorolitik ɓeydi heen bake-out toowɗo ko jaabawol ɓurngol heewde.

Yeeso siifngo ko toɓɓere woɗnde ɓurnde waasde. Sifaa ɓuuɓri tuugii ko e O-ring walla sifaa njamndi, e ɓuuɓri e laaɓal oon yeeso ina felliti tolno ɓuuɓri to bannge. Smoother wonaa otomatik ɓuri moƴƴude : polishing ɓurtuɗo ina itta mbaawka jogaade lubricant e nodda ɓuuɓri e nder mooɓondiral. Bannge sensible oo heewi wonde ko Ra 0,4 haa 0,8, alaa ko ɓuuɓnata ɗum, alaa ko woni e mum.

Laaɓal Ina Jogaa Gila e Taƴre Gadane

Laaɓal feeñataa e lootgol timmungol ; ina toppitee gila e golle gadane ɗee. Ɓeydagol sulfuur e kuloor e nder cooyngal ina naata e nder mikroo-porosite aluminium, ina saɗi no feewi ittude caggal ɗuum. Nebam e dow fiɓnde, duƴƴe e dow konveyoruuji e plastikiser ummoraade e paaspooruuji fof ngonta ko ɓuuɓri e joofnirde.

Butikuuji baɗooji semmbeeji walla elektoronik ko ɗum waɗi ina njiɗi laabi laaɓtuɗi — ultrasonic, DI rinse, dry — e ƴeewndo sahaa e sahaa fof e limto partikulaaji. So aɗa ƴeewndotoo joloowo ina moƴƴi ƴeewde oon liggey : so tawii pecce ɗee ina ndenndi loowdi e golle gaadoraaɗe, laaɓal waawaa dañeede. Ko ɗum kadi ɓuri heewde ƴaañde so peewnugol njamndi mboɗeeri e pecce stamping naatii e njuɓɓudi semiconductor.

Finnde Surface: Geɗe tati, Riisuuji tati

Ko heewi e mbaydiiji elektoronik ina njiytoo heen gooto e finirɗe tati : anodising, coftal waylude kemikal ko wayi no kromat gonɗo e jolngo, walla pentugol. Anodising ina insulate e ina haɗa ɓoornaade kono ina mawnina feccere ndee e mikroo tati haa jeetati e yeeso kala, ko ɗum waɗi ɓulli threaded ina poti maskude. Coating waylo-waylo ina jogori waɗde e waylude dimensiyonji seeɗa, ko ɗum fotndi e toɓɓe leydi. Pentiir ina soomi kono ina yalta e les vacuum walla nguleeki.

Muñal e Moɓondiral: Njuuteeki Kaɓirgal Ko Mahi, Wonaa Masiŋaaji

E dow pecce kaɓirɗe ngam kaɓirɗe semiconductor muñal pecce goote ina famɗi caɗeele ; majjere mooftaande e mooɓondiral ko. Kaɓirgal meeteruuji ɗiɗi peewniraangal sappo e ɗiɗi ekstraksiyoŋaaji e pilaate, heen gooto fof ina jogii ɓeydaare walla ustude 0,1mm, ina waawi mooftude milimeeteeruuji ɗiɗi yaltude. Jaabawol ngol wonaa tiiɗtinde kala feccere haa 0,02mm, ko ɗum ɓeydata njoɓdi, kono ko huutoraade shims fitting e adjusting matched.

Ɗum firti ko diisnondiral ngam ƴeewndo peewnugol ina foti seerndude dimensiyonji mooɓondiral e dimensiyonji golle. Dimensiyonji mooɓondiral ina mbaawi soomde majjere mooftaande rewrude e njuɓɓudi ; dimensiyonji gollal, ko wayi no yeeso montage rail, ina foti jogaade ko yaawi.

Paaspoor e yah-ngartaa : Pecce laaɓtuɗe ina ŋakkiraa e sahaa udditgol

Laɓɓingol ina waawi yettaade noogaas e jeenay e nder teemedere, haa jooni ina ŋakki e paaspoor. Mode ŋakkeende tippudi e pecce kaɓirɗe semiconductor ko contamination e udditgol : pecce ɗee ina laaɓi, kono saak oo yaltinii plasticiser, dust desiccant dogi, walla etiket kaayitaaji jooɗii hakkunde laabi saakuuji ɗiɗi ɗii, ruttitii kala ko woni e dow mum e udditde.

Sifaa paaspoor moƴƴo ina soomi geɗe nay. Layer nder oo ko saak ɗiɗo cleanroom-grade wonaa filmo PE ordinateer. Saak oo ko azot purge walla vacuum ngam haɗde adsorption. Desiccant ko gooto fof siiltee mbele hay duƴƴe ina njalta. Kaɓirgal yaajngal huutortoo ko kaayitaaji cleanroom walla bubble wrap e nokku ɗo alluwal gonngal e jokkondiral toowngal e feccere ndee. Ngam geɗe sensitive outgassing, silikon ɓuuɓɗo e kaayitaaji nebam anti-rust ina poti yaltineede kadi.
