I-Flux yinto ebalulekileyo encedisayo kwi-welding yebhodi yesekethe ye-PCBA.Umgangatho we-flux uya kuchaphazela ngokuthe ngqo umgangatho wereflow oven.Makhe sihlalutye ukuba kutheni i-flux ibaluleke kangaka.
1. umgaqo we-welding we-flux
I-Flux inokuthwala umphumo we-welding, kuba ii-athomu zetsimbi zisondelene nomnye emva kokusabalalisa, ukuchithwa, ukungena kunye nezinye iziphumo.Ukongeza kwimfuno yokuhlangabezana nokususwa kweeoksidi kunye nezingcolisi ekusebenzeni kokusebenza, kodwa kunye nokuhlangabezana ne-non-corrosive, i-insulation, ukumelana nokufuma, ukuzinza, ukungabi nabungozi, ukucoceka kunye nezinye iimfuno.Ngokuqhelekileyo, iinqununu zayo eziphambili ziyi-agent esebenzayo, ifilimu - ukwenza izinto, izongezo, i-solvents kunye nokunye.
2. Susa i-oxide ebusweni bentsimbi edibeneyo
Kwimekobume yomoya eqhelekileyo, kuhlala kukho iioksidi kumphezulu wesinyithi wepadi yokuwelda.Ezi oxides ziya kuba nempembelelo ethile ekumanziseni kwe-solder ngexesha lenkqubo ye-welding, eya kuchaphazela inkqubo ye-welding kunye neziphumo ze-welding.umatshini wokuphinda uphinde udibanise.Ke ngoko, i-flux kufuneka ikwazi ukunciphisa i-oksidi, kwaye ukuwelda kwePCBA kunokwenziwa ngokuqhelekileyo.
3. Ukuthintela i-oxidation yesibini
Kwinkqubo ye-welding ye-PCBA processing, ukufudumeza kuyadingeka.Nangona kunjalo, kwinkqubo yokufudumala, i-oxidation esheshayo iya kwenzeka kwindawo yesinyithi ngenxa yokunyuka kweqondo lokushisa.Ngeli xesha, i-flux iyadingeka ukuze idlale indima ekuthinteleni i-oxidation yesibini.
4. Nciphisa uxinzelelo lwesolder etyhidiweyo
Ngenxa yokwakheka komzimba, umphezulu we-solder otyhidiweyo uya kuba noxinzelelo oluthile, kwaye ukuxinana komphezulu kuya kukhokelela kwisantya sokuhamba kwe-solder ukuya kwindawo ye-welding ukuchaphazela ukumanzisa okuqhelekileyo kwinkqubo ye-welding, kunye nomsebenzi we-flux kule. ixesha kukunciphisa uxinzelelo lomphezulu we-solder engamanzi, ukwenzela ukuba ukumanzi kunokuphucula kakhulu.
