1. Uhlelo lokufafaza lwe-Flux
I-wave soldering ekhethiwe isebenzisa isistimu yokufafaza ye-flux ekhethiwe, okungukuthi, ngemva kokuba i-flux nozzle igijimela endaweni ekhethiwe ngokuvumelana nemiyalelo ehleliwe, indawo kuphela ebhodini lesifunda elidinga ukudayiswa efafazwa nge-flux (spray point and line spray. ayatholakala) , Umthamo wesifutho wezindawo ezahlukene ungalungiswa ngokuya ngohlelo.Ngenxa yokuthi i-spraying ekhethiwe, hhayi kuphela inani le-flux eligcinwa kakhulu uma liqhathaniswa ne-wave soldering, kodwa futhi ligwema ukungcoliswa kwezindawo ezingezona i-soldering ebhodini lesifunda.
Ngenxa yokuthi kuyisifutho esikhethiwe, ukunemba kokulawulwa kwe-flux nozzle kuphezulu kakhulu (kuhlanganise nendlela yokushayela ye-flux nozzle), futhi i-flux nozzle kufanele futhi ibe nomsebenzi wokulinganisa okuzenzakalelayo.Ukwengeza, ohlelweni lokufafaza okuguquguqukayo, ukukhethwa kwempahla kufanele kucabangele ukugqwala okuqinile kokugeleza okungeyona i-VOC (okungukuthi ukuguquguquka okuncibilika emanzini).Ngakho-ke, nomaphi lapho kungenzeka khona ukuthintana ne-flux, izingxenye kufanele zibe Ingakwazi ukumelana nokugqwala.
2. Imojuli yokushisa
Ukushisa kwebhodi lonke kuyisihluthulelo.Ngoba ibhodi lokushisa eliphelele lingavimbela ngokuphumelelayo izikhundla ezahlukene zebhodi lesifunda ukuthi zingashisi ngokungalingani futhi zibangele ibhodi lesifunda ukuba lishintshe.Okwesibili, ukuphepha nokulawula ukushisa kwangaphambi kwesikhathi kubaluleke kakhulu.Umsebenzi oyinhloko wokushisa kuqala ukwenza kusebenze i-flux.Njengoba ukusebenza kwe-flux kuqediwe ngaphansi kwebanga elithile lokushisa, kokubili izinga lokushisa eliphezulu kakhulu neliphansi kakhulu kuyingozi ekwenzeni kusebenze ukugeleza.Ngaphezu kwalokho, amadivaysi ashisayo ebhodini lesifunda nawo adinga ukushisa okushisa okulawulwayo, ngaphandle kwalokho amadivaysi ashisayo angase alimale.
Ukuhlola kubonisa ukuthi ukushisa okwanele ngokwanele kunganciphisa isikhathi sokushisela futhi kwehlise izinga lokushisa lokushisela;futhi ngale ndlela, ukukhishwa kwe-pad kanye ne-substrate, ukushaqeka okushisayo ebhodini lesifunda, kanye nengozi yokuncibilika kwethusi nayo iyancishiswa, futhi ukwethembeka kwe-welding ngokwemvelo kuyancipha kakhulu.ukwanda.
3. Imojula yokushisela
Imojula yokushisela ngokuvamile iqukethe isilinda sikathayela, iphampu esebenza ngomshini/kagesi, umlomo wombhobho wokushisela, idivayisi yokuvikela i-nitrogen kanye nedivayisi yokudlulisela.Ngenxa yesenzo sepompo likamshini/kagesi, i-solder ethangini likathayela izoqhubeka nokuphuma kubhobho lokushisela elima mpo, lenze igagasi lethini eliguquguqukayo elizinzile;idivayisi yokuvikela i-nitrogen ingavimbela ngokuphumelelayo umbhobho wokushisela ukuthi ungavinjelwa ngenxa yokukhiqizwa kwe-tin slag;kanye nedivaysi yokudlulisela Ukunyakaza okunembile kwesilinda sethayela noma ibhodi lesekethe kuqinisekiswa ukuze kubonakale ukushisela iphuzu nephuzu.
1. Ukusetshenziswa kwe-nitrogen.Ukusetshenziswa kwe-nitrogen kungandisa ukudayiswa kwe-solder yomthofu izikhathi ezingu-4, okubaluleke kakhulu ekuthuthukisweni okuphelele kwekhwalithi ye-lead soldering.
2. Umehluko oyisisekelo phakathi kwe-solder ekhethiwe kanye ne-dip soldering.I-Dip soldering iwukucwilisa ibhodi lesifunda ethangini likathayela futhi uthembele ekucindezelekeni kwangaphezulu kwe-solder ukuthi ikhuphuke ngokwemvelo ukuqedela ukuhlanganisa.Ngomthamo omkhulu wokushisa namabhodi wesekethe we-multilayer, kunzima ukucwilisa i-dip ukuze kuhlangatshezwane nezidingo zokungena kwe-tin.Ukukhethwa kwe-soldering kuhlukile.Igagasi likathayela eliguquguqukayo likhishelwa ngaphandle kwembobo yokunamathisela, futhi amandla alo ashukumisayo azothinta ngokuqondile ukungena kwethayela okume mpo emgodini odlulayo;ikakhulukazi ekufakweni komthofu, ngenxa yokungemanzi kahle kwayo, idinga igagasi lethini elinamandla.Ngaphezu kwalokho, ama-oxide angeke ahlale emagagasi anamandla agelezayo, azosiza futhi ukuthuthukisa ikhwalithi yokushisela.
3. Ukusetha imingcele yokushisela.
Ukuze uthole amaphuzu ahlukene we-welding, i-welding module kufanele ikwazi ukwenza isikhathi somuntu siqu, ubude begagasi kanye nesikhundla sokushisela, okuzonikeza unjiniyela wokusebenza isikhala esanele sokulungisa inqubo, ukuze umphumela wokushisela wephoyinti ngalinye le-welding ungafinyelelwa..Eminye imishini yokushisela ekhethiwe ingafinyelela ngisho nomphumela wokuvimbela ibhuloho ngokulawula ukuma kwamalunga e-solder.
4. Uhlelo lokudlulisa ibhodi lesifunda
Isidingo esiyinhloko sokudayiswa okukhethiwe ohlelweni lokudlulisa ibhodi lesifunda ukunemba.Ukuze kuhlangatshezwane nezidingo zokunemba, isistimu yokudlulisa kufanele ihlangabezane namaphuzu amabili alandelayo:
1. Impahla yethrekhi imelene nokuguqulwa, izinzile futhi ihlala isikhathi eside;
2. Faka idivayisi yokubeka endaweni yethrekhi ngokusebenzisa imojuli yokufafaza i-flux kanye nemojula yokushisela.Izindleko eziphansi zokusebenza ze-welding ekhethiwe yisizathu esibalulekile sokuthi kungani yamukelwa ngokushesha ngabakhiqizi.
