1. Inkqubo yokutshiza ngeFlux
Ukunyuswa kwamaza okukhethiweyo kwamkela inkqubo yokutshiza ekhethiweyo, oko kukuthi, emva kokuba umbhobho we-flux ubaleke kwindawo echongiweyo ngokwemiyalelo ecwangcisiweyo, kuphela indawo ekwibhodi yesekethe efuna ukuthengiswa ifafazwe nge-flux (inqaku lokutshiza kunye nesitshizi somgca). ziyafumaneka) , Umthamo wokutshiza weendawo ezahlukeneyo unokuhlengahlengiswa ngokwenkqubo.Ngenxa yokuba kukhetha ukutshiza, kungekhona kuphela inani le-flux eligcinwe kakhulu xa kuthelekiswa ne-soldering ye-wave, kodwa iphinda ithintele ukungcoliseka kweendawo ezingenayo i-soldering kwibhodi yesekethe.
Ngenxa yokuba i-spraying ekhethiweyo, ukuchaneka kokulawulwa kombhobho we-flux kuphezulu kakhulu (kubandakanywa nendlela yokuqhuba i-nozzle ye-flux), kunye ne-nozzle ye-flux kufuneka ibe nomsebenzi wokulinganisa ngokuzenzekelayo.Ukongezelela, kwinkqubo yokutshiza i-flux, ukukhethwa kwezinto eziphathekayo kufuneka kuthathelwe ingqalelo ukubola okuqinileyo kwe-non-VOC fluxes (oko kukuthi i-fluxes e-soluble yamanzi).Ke ngoko, naphi na apho kukho ithuba lokunxibelelana ne-flux, iinxalenye kufuneka zibe Iyakwazi ukumelana nokubola.
2. Imodyuli yokufudumeza
Ukufudumala kwebhodi yonke kungundoqo.Ngenxa yokuba ibhodi yokutshisa ibhodi yonke inokuthintela ngokufanelekileyo izikhundla ezahlukeneyo zebhodi yesekethe ukuba ifudumale ngokungalingani kwaye ibangele ukuba ibhodi yesekethe ikhubaze.Okwesibini, ukhuseleko kunye nokulawulwa kokushisa kwangaphambili kubaluleke kakhulu.Umsebenzi oyintloko wokushisa kwangaphambili kukuvula i-flux.Ekubeni ukusebenza kwe-flux kugqityiwe phantsi komgangatho othile weqondo lokushisa, zombini ukushisa okuphezulu kunye nokuphantsi kakhulu kuyingozi ekusebenzeni kwe-flux.Ukongezelela, izixhobo zokufudumala kwibhodi yesiphaluka nazo zifuna ukushisa okulawulwayo kwangaphambili, ngaphandle koko izixhobo zokushisa zinokuthi zonakaliswe.
Iimvavanyo zibonisa ukuba ukufudumala okwaneleyo kunokunciphisa ixesha lokutshisa kunye nokunciphisa ubushushu be-welding;kwaye ngale ndlela, i-peeling ye-pad kunye ne-substrate, ukutshitshiswa kwe-thermal kwibhodi yesiphaluka, kunye nomngcipheko wobhedu onyibilikayo nawo uyancitshiswa, kwaye ukuthembeka kwe-welding ngokwemvelo kuyancipha kakhulu.Nyusa.
3. Imodyuli yokuwelda
Imodyuli ye-welding idla ngokuba ne-tin cylinder, mechanical / electromagnetic pump, nozzle welding, isixhobo sokukhusela i-nitrogen kunye nesixhobo sokuhambisa.Ngenxa yesenzo sempompo yomatshini/yombane, i-solder kwitanki ye-tin iya kuqhubeka iphuma kumbhobho we-welding ethe nkqo, yenze i-wave ye-tin eguqukayo ezinzileyo;isixhobo sokukhusela i-nitrogen sinokuthintela ngokufanelekileyo i-nozzle ye-welding ukuba ivalwe ngenxa yokuveliswa kwe-tin slag;kunye nesixhobo sothumelo Ukuhamba ngokuchanekileyo kwe-tin cylinder okanye ibhodi yesekethe kuqinisekiswa ukuqaphela i-point-by-point welding.
1. Ukusetyenziswa kwenitrogen.Ukusetyenziswa kwe-nitrogen kunokunyusa ukuthengiswa kwe-lead solder ngamaxesha e-4, ebaluleke kakhulu ekuphuculeni ngokubanzi umgangatho we-lead soldering.
2. Umahluko osisiseko phakathi kwe-solder ekhethiweyo kunye ne-dip soldering.Idiphu i-soldering kukuntywilisela ibhodi yesekethe kwitanki yenkcenkce kwaye uthembele kuxinzelelo lomphezulu we-solder ukukhwela ngokwendalo ukugqiba i-soldering.Kumandla amakhulu obushushu kunye neebhodi zeesekethe ezininzi, kunzima ukudipha i-soldering ukuhlangabezana neemfuno zokungena kwe-tin.Ukukhethwa kwe-soldering kuyahluka.I-wave ye-tin eguqukayo ikhutshwa ngaphandle kwe-soldering nozzle, kwaye amandla ayo aguqukayo aya kuchaphazela ngokuthe ngqo ukungena kwe-tin kumngxuma odlulayo;ngakumbi kwi-lead soldering, ngenxa yokungamanzi kwayo, ifuna i-dynamic tin wave.Ukongeza, ii-oxides azinakwenzeka ukuba zihlale kumaza anamandla aqukuqelayo, nto leyo eya kunceda ekuphuculeni umgangatho we-welding.
3. Ukusekwa kweeparamitha ze-welding.
Ngamanqaku e-welding ahlukeneyo, imodyuli ye-welding kufuneka ikwazi ukulungelelanisa ixesha le-welding, ukuphakama kwamaza kunye ne-welding position, eya kunika injineli yokusebenza indawo eyaneleyo yokulungelelanisa inkqubo, ukwenzela ukuba isiphumo se-welding sendawo nganye ye-welding sinokufezekiswa..Ezinye izixhobo zokuwelda ezikhethiweyo zinokufikelela kwisiphumo sokuthintela ibhulorho ngokulawula imilo yamalungu e-solder.
4. Inkqubo yokuhanjiswa kwebhodi yesekethe
Imfuno ephambili ye-soldering ekhethiweyo kwinkqubo yokuhanjiswa kwebhodi yesekethe kukuchaneka.Ukuze kuhlangatyezwane neemfuno zokuchaneka, inkqubo yothumelo kufuneka ihlangabezane nala manqaku mabini alandelayo:
1. Izinto zomkhondo zi-anti-deformation, zizinzile kwaye zihlala zihlala njalo;
2. Faka isixhobo sokubeka kwindawo yomzila ngokusebenzisa imodyuli yokutshiza i-flux kunye nemodyuli ye-welding.Iindleko eziphantsi zokusebenza kwe-welding ekhethiweyo sizathu esibalulekileyo sokuba kutheni kwamkelwa ngokukhawuleza ngabavelisi.
