Iyini inqubo yokudalula ukuthengisa?
Inqubo yokudalula ekhethekile iyinqubo ekhethekile yokujoyina ehlanganisa izinto zokuthengisa okujwayelekile nge-arouse-specist aclusion bonding
Umbono osemqoka:
Cabanga ngakho 'ukuthengisa ngokuvuselelwa kwe-metallurgical."
Usebenzisa ai-filler metal(solder) oncibilikayokanye, kodwa ke i-athomicukungcolaiguqula ukuhlanganiswa kube yinto eqinile futhi ezinzile - imvamisa ifana nensimbi emsulwa noma ye-intermetallic .
Inqubo ye- 4-:
1. Ukulungiselela & Umhlangano
- I-PEREFANDS ye-Base Meals (e . g ., ithusi, i-silicon, noma ubumba) ngokucophelelaehlanziwe(Ukususa oxides / okonakele) .
- Ungqimba omncane wei-filler metal(solder alloy njenge-au-SN, i-AG-SN, noma okusekwe ngaphakathi) ibekwe phakathi kwezingxenye . Lo mfeli une-aIphuzu eliphansi eliphansikunezinto zokwenziwa kwezisekelo .
- Izingxenye ziboshwe ngaphansiIngcindezi elinganiselayoUkuqinisekisa ukuthintana .
2. Isigaba sokushisa nesikhashana
- Umhlangano ufudumele emazingeni okushisaNgaphezulu kwephuzu lokuncibilika le-filler(e . g ., 300℃for au-sn) .
- I-fillerncibilikakanye nama-wets izinsimbi eziyisisekelo, zakha okwesikhashanaungqimba oluwuketshezi(Njengomthengisi ojwayelekile) .
- Umehluko obalulekile:Izinga lokushisa libanjwaNgaphezulu njeIphuzu lokuncibilika le-filler --Iphezulu ngokwanele ukuncibilika izinsimbi eziyisisekelo .
3. ukuqina okusobala nge-defalion
- Le khasiImilingo yenzeka lapha:Ama-athomu avela kwi-base metal (e . g ., CU noma NI)hlukana ngokusheshaku-molten solder .
- Ngasikhathi sinye, ama-athomu avela ku-solder (e . g ., SN)hlukana neI-Base Metal .
- Lokhu kushintsha ukwakheka komthengisi,Ukuphakamisa Iphuzu Lawo Lokuncibilika.
- Umphumela: I-FICKER FILERiqinisangaphandle kokupholisaumhlangano . lokhu kubizwasonortheral ukuqina.
- Cabanga ngakho njengokungeza usawoti eqhweni - iphuzu lokuncibilika likhuphuka, futhi liqina ngisho nasekushiseni okufanayo .
4. ukunwetshwa okunwetshiwe kanye ne-homogenization
- Ukushisa kubanjelweimizuzu kuya emahoreni(isikhathi eside kunokuthengisa okujwayelekile) .
- Ama-athomu aqhubeka ehlukile, phambilihomogenizingokuhlangene .
- Ukuhlangana kokugcina kuba yi-: ahomogeneous alloy(Uma i-filler / isisekelo iyahambelana) . noma aungqimba oluncane lwe-intermetallici-sandwiched phakathi kwezinsimbi ezisezingeni (eziqinile, mahhala) .
- Okuhlanganisiwe manje kuncibilika aIzinga lokushisa eliphakeme kakhuluukwedlula i-filler yasekuqaleni - imvamisa eduze nendawo yokuncibilika yensimbi yensimbi!
Kungani usebenzise i-deflising soldering? Izinzuzo ezibalulekile:
| Ukuthengisa okujwayelekile | Ukudalulwa kokuzenzakalelayo |
|---|---|
| Ukuhlangene kuncibilika e-solder's Original MP | I-Joint Beblets EduzeI-Base Metal'sI-MP ephezulu |
| Ithambekele kuma-voids / imifantu | -Nomhlaba, izibopho ezithembekile eziphakeme |
| Ingozi yokuhluleka ukukhathala | Phila ama-cycling ashisayo(e . g ., i-aerospace) |
| Kukhawulelwe kuzinhlelo zokusebenza eziphansi ze-temp | Ilungeleinsizakalo ephezulu ye-temp(Amandla Electronics) |
| I-insermetalics ebuthakathaka | Ukulawulwa okulawulwa(enamandla, kancane) |
Izicelo zangempela zomhlaba:
1. Amandla Electronics:Ukunamathisela ama-chip Carbide (Sic) ama-chip to Copper / DBC Substrates ku-EV Inverters .
2. Aerospace:Ukujoyina ama-turbine blades ngama-alloys amela ukushisa (usebenzisa i-au-ge filler) .
3. opoloelectronics:Ukuvalwa kwe-Laser Diade emaphaketheni ama-hermetic (au-sn filler) .
4. Izimila zezokwelapha:Ukwakha amalunga angenakonakala-mahhala kumadivayisi we-titanium .
Amapharamitha asemqoka ukulawula:
- Ukwakheka kwe-Filler(Kufanele uhlanganyele ngokungahambi kahle ngensimbi eyisisekelo) .
- Iphrofayili yokushisa(Ukunemba ± 5℃kaningi okudingekayo) .
- Isikhathi sokushisa(Yazisa ukujula kokuphamba) .
- Ukucindezela(iqinisekisa ukuthintwa ngemvume kepha ayizenzi izingxenye) .
Kafushane:I-Difsision Soldering incibilika i-fillerkanye, bese usebenzisaUkuvikelwa kwe-athomu eqhutshwa ukushisaUkuthi "ukuthuthukisa" ukuhlanganiswa kube yi-pointing ephezulu-coibiling-. Yindlela yokuhamba lapho ukwehluleka ekukhathazekeni okushisayo noma ukuncibilikisa akuyona inketho! 🔥🔬
