I-Diffusion bonding welding, ekwabizwa ngokuba yi-diffusion welding, yinkqubo eqinileyo-yenkqubo yokudityaniswa kwelizwe esebenzisa ubushushu obulawulwayo, uxinzelelo kunye nexesha lokudibanisa imiphezulu esondeleleneyo ngaphandle kokunyibilikisa imathiriyeli esisiseko. Umgangatho odibeneyo uxhomekeke kulungiselelo lomphezulu, ukuhambelana kwezinto, ubushushu, uxinzelelo olusetyenzisiweyo kunye nexesha lokubamba
Eli gama ngamanye amaxesha libhidaniswa ne-diffusion soldering okanye i-transent liquid phase bonding. Ezi nkqubo zihlobene, kodwa azifani. Ukudityaniswa kokusasazwa okuqhelekileyo kugcina ujongano oludityanisiweyo lukwimeko eqinileyo, ngelixa i-diffusion soldering isebenzisa i-interlayer ethi ibe lulwelo okwethutyana.
Eli nqaku lichaza indlela inkqubo yokudibanisa i-diffusion isebenza ngayo, eziguquguqukayo ezichaphazela umphumo kunye nendlela inkqubo esebenza ngayo kwi-copper laminated copper kunye ne-aluminium conductors.
Yintoni iDiffusion Bonding Welding?
I-Diffusion bonding welding yinkqubo apho iindawo ezimbini ezilungiselelwe zibanjwe kunye phantsi kobushushu obulawulwayo kunye noxinzelelo. Uqhagamshelwano olusondeleyo kujongano luvumela ukudibanisa ukuba kuphuhliseke kwiindawo zokukhwelana ngokuhamba kwexesha.
Izinto ezisisiseko zihlala zingaphantsi kwamaqondo obushushu anyibilikayo. Ubushushu bunyusa ukuhamba kwezinto, ngelixa uxinzelelo luzisa umphezulu kunxibelelwano olusondeleyo kwaye lunceda ukuvala izikhewu ezincinci. Ixesha lokubamba livumela i-interface ukuba iphuhlise ibe yimbumba edibeneyo.
Idiffusion bonding kunye nediffusion welding zisetyenziswa ngokubanzi njengamagama enkqubo efanayo eqinileyo-yelizwe. Indlela ingasetyenziswa kwizinto ezifanayo okanye ezingafaniyo, nangona ukudibanisa okungafaniyo kufuna ingqalelo eyongezelelweyo ekwandiseni i-thermal, ukubunjwa kwe-oxide kunye nokuphendula okubonakalayo okunokwenzeka.
Ngokwenkcazo ye-TWI yokudibanisa i-diffusion, ubume bomphezulu, ubushushu, uxinzelelo kunye nomoya wokulungisa zizinto ezibalulekileyo ekuphumezeni isandi esidibeneyo.
Ukudityaniswa kweDiffusion vs. Diffusion Soldering
Ukudityaniswa kokudibanisa akufuneki kusetyenziswe njengegama eliqhelekileyo kuyo yonke inkqubo yokudibanisa ebandakanya ukusasazwa kweatom.
I-Diffusion soldering, ekwaziwa ngokuba yi-transient liquid phase bonding, isebenzisa{0}}i-interlayer ephantsi yokunyibilika. I-interlayer iyanyibilika ngexesha lokufudumeza kwaye yenza isigaba sexeshana solwelo. Njengoko ii-elementi zisasazeka phakathi kwe-interlayer kunye nemathiriyeli yesiseko, ukwakheka kweenguqu ezidibeneyo kunye nolwelo luyaqina ngelixa ubushushu lusabanjwa.
Unxulumano oluqinileyo oluqhelekileyo-lobume bokusasazwa aluxhomekekanga kwesi sigaba solwelo sexeshana.
| Inkqubo uphawu | I-Solid-I-State Diffusion Bonding | I-Diffusion Soldering okanye i-TLP Bonding |
| Imeko kujongano | Ujongano luhlala luqinile | I-interlayer yenza isigaba solwelo sexeshana |
| Isigcwalisi okanye i-interlayer | Ngokuqhelekileyo akufuneki kwizinto ezifanayo | Ngokwesiqhelo ifuna isithuba esisezantsi{0}} esinyibilikayo esinyibilikayo |
| Indlela yokudibanisa engundoqo | Uqhagamshelwano lomphezulu, uguquko lwasekuhlaleni kunye-nolwazo oluqinileyo | Ukunyibilika, ukumanzisa, ukusasazwa kunye nokuqiniswa kwe-isothermal |
| Ulawulo oluphambili | Ubume bomphezulu, ubushushu, uxinzelelo, ixesha kunye nomoya | Ukwakhiwa kwe-Interlayer, ubushushu, ixesha kunye neempendulo zojongano |
| Usetyenziso oluqhelekileyo | Izakhiwo ezilayiweyo, abatshintshisi bobushushu, amacandelo e-aerospace kunye nee-conductor | Umbane wamandla, i-microelectronics kunye neendawo ezikhethiweyo zobushushu obuphezulu-ezidibeneyo |
Ukwahlula kubalulekile xa ukhetha izixhobo. Iziko{{1}ezisekwe kwinkqubo yokusasazwa kwebhondi, inkqubo ye-TLP yebhondi kunye nokuxhathisa{2}}ifoyile yobhedu eshushu yokusasazwa kwewelder ayinyanzelekanga ukuba isebenzise isixhobo esifanayo, umoya okanye umjikelo wenkqubo.
Isebenza Njani Inkqubo yeDiffusion Bonding?
Inkqubo ye-diffusion bonding ebonakalayo inokwahlulwa ibe ngamanqanaba amahlanu aphambili.
1. Lungisa i-Bonding Surfaces
Imiphezulu kufuneka icoceke ngokwaneleyo ukwenza unxibelelwano olusondeleyo noluphinda-phindayo. I-oyile, i-oxidi ekhululekile, i-polish i-residu kunye ne-particle inokuthintela amacandelo e-interface kwi-bonding.
Ukulungiswa komphezulu kuxhomekeke kwizinto kunye nemfuno yemveliso. Ingabandakanya umatshini, ukubetha okulawulwayo, ukuthoba amafutha okanye enye inkqubo yokucoca evunyiweyo. Umphezulu ocociweyo kufuneka ukhuselwe ekuphathweni ngokungeyomfuneko kunye nongcoliseko phambi kokuhlanganiswa.
I-Flatness kunye nokugqitywa komphezulu kwakhona kuchaphazela indawo yokudibanisa yokwenene. Umphezulu obonakalayo othe tyaba usenawo amanqaku aphezulu naphantsi. Uxinzelelo olusetyenzisiweyo lusebenza kuqala kwiindawo eziphezulu, ngoko ke uburhabaxa obugqithisileyo okanye ukutyeba okulambathayo kunokushiya iindawo ezingabotshwanga.
Ukucoca kukodwa akunakulungisa ijoyini engafakwanga kakuhle. Ukulungiswa komphezulu, imilinganiselo yeenxalenye kunye nokulungelelaniswa kwesakhiwo kufuneka kuqwalaselwe kunye.
2. Hlanganisa kwaye ulungelelanise amaCandelo
Amacandelo abekwe kwi-fixture okanye kwi-tooling system egcina i-bonding surfaces ihambelana. Kwi-stack ye-copper okanye i-aluminium foil, iileyile kufuneka zilungelelaniswe ngokulinganayo ukwenzela ukuba iifolthi, iinqununu ezibanjwe okanye imiphetho engalinganiyo ingaphazamisi ukusabalalisa uxinzelelo.
Ukulungiswa kufuneka kuxhase i-workpiece ngaphandle kokuthintela indlela efunekayo yangoku, ukuhanjiswa kobushushu okanye ukunyakaza kwezixhobo. Ukuba kuphela inxalenye yendawo yokudibanisa ifumana amandla aneleyo, ukudibanisa okugqityiweyo kunokuquka izikhewu zendawo nangona izicwangciso zomatshini zibonakala zichanekileyo.
Ngaphambi kokufudumeza, khangela:
- Ibakala lezinto eziphathekayo kunye nemeko yomhlaba
- Ukutyeba kunye nenani leeleya
- Indawo yokudibanisa kunye necandelo lokugqibela -lomnqamlezo
- Isikhundla somdibaniso ngaphakathi kwesixhobo
- Uqhagamshelwano phakathi kobuso boxinzelelo kunye nomsebenzi
- Imilinganiselo efunekayo egqityiweyo
Ezi nkcukacha kufuneka zirekhodwe njengenxalenye yeshedyuli ye-welding.
3. Faka ubushushu obulawulwayo kunye noxinzelelo
Ukushisa kwandisa izinga lokuhamba kwezinto kwi-interface. Uxinzelelo luphucula unxibelelwano phakathi kwemigangatho kwaye lunceda ukuvala izithuba ezincinci.
Ubushushu bunokubonelelwa ngesithando somlilo, inkqubo yokungeniswa, ukuxhathisa kombane okanye omnye umthombo olawulwayo. Indlela echanekileyo ixhomekeke kwi-workpiece, izinto eziphathekayo kunye nenkqubo yokuvelisa.
Uxinzelelo lunokusetyenziswa ngoomatshini, nge-hydraulically, i-pneumatically okanye ngenkqubo yamandla edibeneyo. Umoya womatshini{1}ufundo loxinzelelo akufunekanga uphathwe ngokuzenzekelayo njengolona xinzelelo kwijoyini. Indawo yezixhobo, ubungakanani besilinda kunye nomatshini womatshini zonke zichaphazela amandla anikezelweyo kwindawo yokusebenza.
Ubushushu kunye noxinzelelo kufuneka ziphuhliselwe indibaniselwano ethile yezinto. Ukonyusa naliphi na ixabiso akuvelisi ngokuzenzekelayo ilungu elingcono. Ubushushu obuncinane kakhulu okanye amandla angashiya ukudityaniswa okungaphelelanga, ngelixa iimeko ezigqithisileyo zinokubangela ukuguqulwa okungafunekiyo, umonakalo ongaphezulu okanye iingxaki zezixhobo.
4. Bamba iNdibanisela phantsi kweeMeko eziZinzile
Amalungu ahlala phantsi kobushushu obulawulwayo kunye nokunyanzeliswa kwexesha elichaziweyo. Ngeli nqanaba, ujongano luyakhula njengoko unxibelelwano luphucuka kwaye usasazo luqhubeka kuyo yonke imiphezulu yokudibanisa.
Ixesha lokubamba lixhomekeke kwi:
- Uhlobo lwezinto
- Ubushushu bokubambisana
- Uxinzelelo olusetyenzisiweyo

- Inani kunye nobukhulu beeleya
- Indlela yokufudumeza izixhobo
- Iipropati ezifunekayo ezidibeneyo
Ixesha lokubamba ixesha elide alisoloko lingcono. Inokunyusa ixesha lomjikelo kwaye inokuba negalelo kuguquko olugqithisileyo okanye ukuphendula okungafunekiyo kojongano kwezinye izinto ezidityanisiweyo.
Injongo kukuseka inkqubo yefestile evelisa ukudibanisa okuphindaphindiweyo phantsi kweemeko eziqhelekileyo zemveliso.
5. Pholisa kwaye uhlole iBond
Umdibaniso upholile ngokwenkqubo eqinisekisiweyo. Ukunyanzeliswa kungadinga ukugcinwa ngexesha lesigaba sokupholisa ukukhusela ukudibanisa kunye nokunyakaza kokulawula.
I-workpiece ayifanele isuswe kuphela ngenxa yokuba ixesha lokufudumala elicwangcisiweyo liphelile. Iimeko zokukhutshwa kufuneka ziqwalasele ubushushu benxalenye, ubushushu besixhobo kunye nomngcipheko wokuguqulwa.
Emva kokususwa, umdibaniso uhlolwe ngokusebenzisa iindlela ezifunwa yinkcazo yemveliso. Imbonakalo iluncedo ekuchongeni iingxaki ezingaphezulu, kodwa ayinakuqinisekisa imeko epheleleyo yojongano lwangaphakathi.
