1. Wave Soldering TshuabCov txheej txheem thev naus laus zis
Dispensing → thaj → kho → yoj soldering
2. Cov yam ntxwv txheej txheem
Qhov loj thiab ntim ntawm cov sib koom ua ke yog nyob ntawm qhov tsim ntawm lub ncoo thiab qhov sib txawv ntawm lub qhov thiab cov hlau lead.Tus nqi ntawm cov cua sov siv rau PCB feem ntau yog nyob ntawm qhov kub ntawm lub molten solder thiab lub sij hawm sib cuag (lub sij hawm vuam) thiab cheeb tsam ntawm lub molten solder thiab PCB.
Feem ntau, cov cua kub tuaj yeem tau txais los ntawm kev kho qhov hloov ceev ntawm PCB.Txawm li cas los xij, qhov kev xaiv ntawm qhov chaw sib cuag rau lub npog ntsej muag tsis yog nyob ntawm qhov dav ntawm lub crest nozzle, tab sis ntawm lub tais qhov rais loj.Qhov no yuav tsum tau hais tias qhov kev teeb tsa ntawm cov khoom ntawm lub vuam nto ntawm lub npog ntsej muag yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm qhov tsawg kawg nkaus qhov rais loj ntawm lub tais.
Muaj "shielding effect" nyob rau hauv vuam nti hom, uas yog ib qho yooj yim rau tshwm sim ntawm vuam to.Shielding yog hais txog qhov tshwm sim uas lub pob ntawm cov khoom nti tiv thaiv cov yoj yoj los ntawm kev hu rau lub ncoo / solder kawg.Qhov no yuav tsum tau hais tias qhov ntev ntawm cov nthwv dej crest welded nti tivthaiv yuav tsum tau teem rau perpendicular mus rau kis tau tus mob kev taw qhia thiaj li hais tias ob welded kawg ntawm lub nti tivthaiv yuav zoo wetted.
Wave soldering yog daim ntawv thov ntawm solder los ntawm molten solder tsis.Soldering nthwv dej muaj cov txheej txheem nkag thiab tawm thaum soldering qhov chaw vim qhov txav ntawm PCB.Lub solder yoj ib txwm tawm ntawm qhov chaw nyob rau hauv cov kev taw qhia ntawm disengagement.Yog li ntawd, kev txuas ntawm tus pin ib txwm txuas txuas ib txwm tshwm sim ntawm tus pin kawg uas disengages lub vuam yoj.Qhov no yuav pab tau kom daws tau qhov kev sib txuas ntawm tus choj txuas ntawm tus pin insert connector.Feem ntau, ntev npaum li tus qauv tsim ntawm cov ntaub qhwv lub ntsej muag zoo tom qab tus pin kawg tuaj yeem daws tau zoo.
