Isistimu yokufafaza ye-Flux
Umshini wokunamathisela wamagagasi okhethiwei-flux spraying system isetshenziselwa ukudayiswa okukhethekile, okungukuthi i-flux nozzle igijima iye endaweni ekhethiwe ngokuvumelana neziyalezo ezihlelwe ngaphambilini bese iguquguqula kuphela indawo ebhodini edinga ukudayiswa (ukufafaza amabala kanye nokufafaza ngomugqa kuyatholakala), futhi inani lokufafaza ezindaweni ezahlukene lingalungiswa ngokuvumelana nohlelo.Ngenxa yokufafaza okukhethiwe, akugcini nje ukuthi inani le-flux lisindisiwe uma liqhathaniswa ne-wave soldering, kodwa ukungcoliswa kwezindawo ezingezona i-soldering ebhodini nakho kugwenywa.
Njengoba isifutho esikhethiwe, ukunemba kokulawulwa kwe-flux nozzle kuphezulu kakhulu (kuhlanganise nendlela yokushayela ye-flux nozzle), futhi i-flux nozzle kufanele futhi ibe nomsebenzi wokulinganisa okuzenzakalelayo.
Ngaphezu kwalokho, ukukhethwa kwezinto ezibonakalayo ohlelweni lokufafaza kwe-flux kumele kukwazi ukucabangela ukugqwala okuqinile kwe-non-VOC flux (okungukuthi, i-flux encibilikayo emanzini), ukuze nomaphi lapho kungenzeka khona ukuthintana ne-flux, izingxenye. kumele ikwazi ukumelana nokugqwala.
Preheat Module
Ukhiye wemojula yokushisa ukuphepha nokuthembeka.
Okokuqala, ukushisa kwebhodi eliphelele kungenye yezihluthulelo.Ngoba lonke ibhodi preheating kungavimbela ngempumelelo deformation ibhodi wesifunda okubangelwa ukushisa okungalingani ezindaweni ezahlukene ibhodi.
Okwesibili, ukuphepha nokulawula ukushisa kwangaphambi kwesikhathi kubaluleke kakhulu.Indima eyinhloko yokushisa kuqala ukwenza kusebenze i-flux, ngoba ukusebenza kwe-flux kuqediwe ngaphansi kwebanga elithile lokushisa, izinga lokushisa eliphezulu kakhulu futhi eliphansi kakhulu alilungile ekusebenzeni kwe-flux.Ukwengeza, idivayisi eshisayo ebhodini lesekethe iphinde idinga ukushisa okulawulwayo, noma idivayisi eshisayo cishe izolimala.
Ukuhlolwa kubonise ukuthi ukushisa okwanele nakho kunganciphisa isikhathi se-solder futhi kunciphise izinga lokushisa le-solder;futhi ngale ndlela, i-pad kanye ne-substrate stripping, ukushaqeka okushisayo ebhodini lesifunda, kanye nengozi yethusi encibilikisiwe nayo iyancipha, futhi ukwethembeka kwe-soldering ngokwemvelo kwanda kakhulu.
I-Solder Module
I-soldering module ngokuvamile iqukethe isilinda sikathayela, ipompo yemishini/amandla kazibuthe, umlomo wombhobho we-soldering, idivayisi yokuvikela i-nitrogen, kanye nedivayisi yokudlulisela.Ngenxa yepompo yemishini/kagesi, i-solder ekusilinda ye-solder izophuma ngokuqhubekayo emibhobhweni ehlukene ye-solder ukuze yakhe igagasi le-tin ashukumisayo elizinzile;idivayisi yokuvikela i-nitrogen ingavimbela ngokuphumelelayo imibhobho ye-solder ukuthi ivaleke ngenxa yokukhiqiza amanyela;futhi idivayisi yokudlulisela iqinisekisa ukunyakaza okunembile kwe-solder cylinder noma ibhodi lesifunda ukuze kuzuzwe i-point-by-point soldering.
1. Ukusetshenziswa kwegesi ye-nitrogen.Ukusetshenziswa kwegesi ye-nitrogen kungakhuphula ukuthengiswa kwe-solder-free solder izikhathi ezi-4, okubaluleke kakhulu ekuthuthukisweni okuphelele kwekhwalithi ye-solder-free soldering.
2. Umehluko oyisisekelo phakathi kwe-solder ekhethiwe kanye ne-dip soldering.I-Dip soldering iwukucwilisa ibhodi lesifunda kusilinda kathayela kuncike ekushubeni kwendawo yokukhuphuka kwe-solder yemvelo ukuze kuqedelwe i-solder.Ngomthamo omkhulu wokushisa kanye namabhodi esekethe anezingqimba eziningi, ukucwilisa i-solder kunzima ukufeza izidingo zokungena kwe-tin.I-soldering ekhethiwe ihlukile, njengoba igagasi lethayela eliguquguqukayo eligijima liphuma emlonyeni wokugcwalisa lithinta ngokuqondile ukungena kwethayela elime mpo embotsheni edlulayo;ikakhulukazi i-solder engenawo umthofu, edinga igagasi lethini eliguquguqukayo neliqinile ngenxa yezindawo zayo zokumanzisa ezimbi.Ngaphezu kwalokho, igagasi eligelezayo elinamandla mancane amathuba okuba libe nezinsalela ze-oxide kulo, okuzosiza futhi ekuthuthukiseni ikhwalithi ye-soldering.
3. Ukusetha imingcele ye-solder.
Ngamajoyinti ahlukene e-solder, i-module ye-solder kufanele ikwazi ukwenza izilungiselelo zomuntu ngamunye ze-soldering isikhathi, ukuphakama kwekhanda le-wave kanye nesimo se-solder, okuzonikeza unjiniyela osebenzayo indawo eyanele yokwenza izinguquko zenqubo ukuze i-solder ngayinye ihlanganiswe kahle.Eminye imishini yokudambisa ekhethiwe inamandla okuvimbela ukuhlangana ngokulawula ukwakheka kwejoyinti le-solder.
Uhlelo lwezokuthutha lwe-PCB
Imfuneko eyinhloko ye-solder ekhethiwe yesistimu yokudlulisa ibhodi ukunemba.Ukuze kuzuzwe izidingo zokunemba, isistimu yokudlulisa kufanele ihlangabezane namaphuzu amabili alandelayo.
1. I-track material ayiguquki, izinzile futhi ihlala isikhathi eside.
2. Imishini yokumisa yengezwa kumathrekhi adlula kumojula ye-flux spray kanye ne-solder module.
Izindleko eziphansi zokugijima ngenxa ye-welding ekhethiwe
Izindleko eziphansi zokusebenza ze-welding ezikhethiwe ziyisizathu esibalulekile sokuthandwa kwayo ngokushesha nabakhiqizi.
