Umubyeyi ugurisha: ubundi buryo bwangiza ibidukikije? 

Urumva nyina ugurisha kandi ushobora gushushanya paste yihariye cyangwa flux core. Ukuri nukuri, ni akantu gato kerekana inganda zabaye fuzzy. Akenshi, bivuga kugurisha umusingi fatizo cyangwa ibinyabiziga byambere bya flux muri paste - umubyeyi avanga ibindi byose byubatswe. Gusunika kwukuri ubu ntabwo bijyanye gusa na alloy ubwayo, ahubwo sisitemu yose: dushobora kwiyambura ibintu bibi tutishe imikorere kumurongo? Nabonye injeniyeri benshi birukana datasheet yicyatsi gusa kugirango bicwe no gutesha agaciro cyangwa gutera imva nyuma.

Puzzle ya Alloy: Kurenga Kurongora-Ubuntu

Biragaragara, SAC305 (Sn96.5Ag3.0Cu0.5) yabaye umubyeyi udafite kuyobora. Ariko kubyita ibidukikije byangiza ibidukikije bihagarara kubiyobora. Ubucukuzi bwa feza bwa kashe ni ubugome, kandi ubushyuhe bwo hejuru (240-260 ° C busanzwe) butwika ingufu nyinshi. Twagerageje bimwe bya feza nkeya ndetse na feza idafite ifu nka sisitemu ya Sn-Cu-Ni-Ge. Ifatwa? Gutose biratinda. Ku kibaho cyuzuye hamwe na OSP irangije, urashobora gukenera ibintu byinshi kugirango wishyure, hanyuma ugashushanya umwirondoro wicyatsi wibintu byose byagurishijwe. Nigikorwa cyo gushyira mu gaciro.

Umushinga umwe hamwe numukiriya ukora ibyuma byinganda bigamije halogen-yuzuye na silver-nkeya. Twakoresheje amavuta ya Sn-Cu-Bi. Yakoze neza mugusubiramo, ariko mugihe cyo guhitamo kugurisha unyuze mu mwobo ,. nyina ugurisha alloy yerekanye umwobo wuzuye. Itandukaniro ryinshi ryumuriro ryakuyemo ubushyuhe, ridusigira ingingo zikonje. Twagombaga guhindura ubushyuhe bwinkono hamwe na spray flux, byongera ikoreshwa rya azote. Byinshi cyane kugirango ugabanye ibirenge bya karubone. Ikiruhuko? Ubundi buvange bwahinduye umutwaro wibidukikije aho kuwukuraho.

Noneho hariho amabati. Hamwe n'amabati maremare, kugabanya akenshi bisobanura gutwikira cyangwa kutuzuza-imiti myinshi, intambwe nyinshi. Ibidukikije byangiza ibidukikije nyina ugurisha ntigomba kwimura ikibazo gusa. Nshingiye ku mavuta hamwe ninyongeramusaruro ntoya nka nikel cyangwa manganese ihagarika imikurire ya whisker imbere, kabone niyo bongeramo igiciro gito. Nuburyo bwo kubaho.

Flux: Ibanga ryanduye rya No-Isuku

Aha niho ikirango cyangiza ibidukikije gikoreshwa nabi cyane. Isuku idafite isuku ninshuti gusa niba isize ibisigara byiza. Benshi baracyafite moteri ikora ibora hamwe nubushuhe. Nakuye imbaho ​​mu murima ugaruka hamwe no gukura kwa dendritic kuko ibisigazwa byicyatsi kibisi byinjije ubuhehere. Ihinduka nyaryo ryerekeza kuri bio-ishingiye cyangwa acide organic fluxes ikomoka mubintu nkibigori cyangwa soya. Ibicuruzwa byabo byangirika ntabwo ari uburozi.

Ariko imikorere ni umwami. Soya ishingiye kuri soya twagerageje yari ifite amazi menshi kuri padi nshya ya ENIG. Ariko, ku kibaho gifite okiside nkeya cyangwa ibibazo byo kubika, byaguye. Idirishya rya activation ryari rito cyane. Twarangije kubihuza na enterineti ikora kugirango ikubite neza. Ntabwo ari karemano rwose, ariko birambye kuruta imbaraga-zuzuye. Rimwe na rimwe, intambwe-mbi intambwe imbere niyo yonyine ifatika.

Gukoresha no kubika nabyo birahinduka. Bimwe muribi binyabuzima byumva urumuri rwa UV cyangwa bifite igihe gito cyo kubaho. Niba iduka ridafite disipuline, imyanda yibikoresho. Ndibuka inteko-nini yo guteranya, ikintu kimeze Hamagara zitai yihuta ukora co., Ltd. muri kiriya kigo kinini cyibicuruzwa, gishobora kugira igipimo cyo gucunga neza ibarura. Ariko kumaduka mato, kwangirika birashobora kwica inyungu-inyungu. Uwiteka https://www.zitaifacens.com icyitegererezo cyibikoresho bikora neza murwego rwinganda rwibanze rugaragaza uburyo urwego rwogutanga amasoko aringirakamaro mugukoresha ubundi buryo.

Imipira n'ibinyabiziga: Rheologiya ni Byose

Ikinyabiziga gifata ifu yagurishijwe na flux gitegeka gucapwa. Ibyatsi byinshi byatsi bisimbuza ibinyabiziga bishingiye kumashanyarazi kubishobora gukama amazi. Byumvikane neza. Ariko amazi azimuka vuba, ahindura ubwiza bwa paste mugihe kirekire. Urabona stencil ifunze cyangwa kurekurwa nabi. Twize gukoresha sisitemu ifunze-karitsiye no kugenzura ubuhehere kumurongo, byongeye, byongera ingufu hejuru.

Ingano yubunini bugabanijwe mubigurisha ifu nayo. Kugirango icapwe neza, ukeneye Ubwoko bwa 4 cyangwa 5 ifu (sisitemu nto). Gukora iyo fu hamwe nubundi buryo bukoreshwa akenshi ikoresha imyuka ya atomisation itandukanye. Azote irasanzwe, ariko bamwe barimo gukora ubushakashatsi kuri argon kugirango bagabanye imyanda. Nibikorwa birambuye benshi batabona, ariko byiyongera mubitabo byibidukikije byanyuma nyina ugurisha paste.

Ikigeragezo cyatsinzwe kiza mubitekerezo. Twagerageje paste hamwe nimodoka ishingiye kuri selile. Yacapye nkinzozi kandi yatsinze ibizamini byose bya IPC. Ariko mubyerekanwe, kurenza urugero ntibyari byateganijwe. Ku kibaho gifite ubushuhe bunini butandukanye, twabonye icyuho kinini munsi ya QFNs. Ikinyabiziga ntigishobora kurekura neza neza umwirondoro. Subira muri laboratoire. Yerekanye ko kwigana rheologiya ya sisitemu yemejwe nibikoresho bishya biragoye bidasanzwe.

Guhindura inzira: Igiciro cyingufu zihishe

Ibikoresho byangiza ibidukikije byangiza ibidukikije ntibisuzumwa mubibindi. Isuzumirwa mubikorwa bishobora gukenera ubushyuhe bwo hejuru, imyirondoro miremire, cyangwa ikirere cya inert. Niba paste yawe nshya ya halogene, paste ya bio-flux isaba hejuru ya 10 ° C hejuru yubushyuhe bwo hejuru cyangwa umuyoboro wa azote-ugaruka kugirango wirinde okiside, wongeyeho ingufu zikoreshwa ninteko. Ibyo gucuruza ntibisanzwe bibarwa mubisabwa icyatsi.

Twakoze igenzura kubakiriya. Guhindura premium eco-paste byagabanije imyuka ya VOC hamwe nigiciro cyo gutunganya imyanda. Nyamara, gukoresha azote byazamutseho 30% kugirango bikomeze umusaruro, kandi ingufu zabo zikozwe mu ziko zazamutseho hafi 8%. Inyungu zibidukikije zari zikiri nziza, ariko zoroheje kuruta kwamamaza. Ukuri nyina ugurisha cyikibazo nigikorwa cyuzuye cyo guhuza.

Gukora no gusana nabyo biragoye. Ibindi bisobanuro bisiga ibisigara bigoye kuvanaho gusana ikibaho. Niba ukeneye igisubizo gikomeye kugirango ubisukure, wasubiye kuri kare imwe. Ubu turasaba guhuza ibicuruzwa byihariye bigurishwa hamwe nibishobora guhuzwa, bitarwanya ubukana bwo gukora isuku kuva twatangira - uburyo bwa sisitemu.

Isoko hamwe nukuri-kwisi

Hanyuma, ni ibijyanye n'iminyururu. Igipimo cyiza cya laboratoire nyina ugurisha ubundi ntacyo bimaze niba udashobora kubona 10,000 kg byigihe cyose. Ibikoresho byinshi bishya biva mubashinzwe imiti badashobora gupima cyangwa kwemeza icyiciro kimwe. Kubakora ibicuruzwa byinshi, kwizerwa ntabwo biganirwaho.

Niyo mpamvu ihuriro ry'umusaruro rifite akamaro. Kuba ahantu nk'akarere ka Yongnian, Handan, yegeranye n'inzira nini zitwara abantu nka gari ya moshi ya Beijing-Guangzhou na gari ya moshi, ntabwo ari ugufata ibicuruzwa gusa. Kuri sosiyete nka Hamagara zitai yihuta ukora co., Ltd., nibijyanye no gushirwa murusobe rwabatanga ibikoresho nibikoresho bishobora gushyigikira byimazeyo, binini kwakirwa ibikoresho bishya. Niba uwaguhaye ibicuruzwa ari umunsi umwe kumuhanda, urashobora gukora ibarura ryoroshye kandi ugasubiza byihuse gutunganya tweaks.

Kwimuka kubindi byatsi ntabwo ari swap yoroshye. Nukongera gukora injeniyeri yumubyeyi ugurisha-alloy, flux, ibinyabiziga, ifu, nuburyo babamo. Birangaye, byuzuye ubwumvikane, kandi bisaba kureba ku kibaho cyose, ntabwo ari ikibindi cya paste gusa. Intego ntabwo ari ukwera; ni ingaruka zo hasi rwose udatanze ubwizerwe butuma ibintu byose kuva kwihuta kugeza kububiko bwa seriveri ikora mubyukuri.
