Chii chinonzi reflow soldering?
Reflow soldering inoreva kushandiswa kwe solder paste kubatanidza chimwe kana zvimwe zvinhu zvemagetsi kune mapedhi ekusangana, uye kunyungudutsa solder kuburikidza nekudziya kunodzorwa kuti uwane chisungo chisingaperi.Nzira dzakasiyana dzekudziya dzakadai sereflow oveni, marambi ekudziya infrared, kana pfuti dzekupisa dzinogona kushandiswa.yewelding.Reflow soldering ndiyo inonyanya kushandiswa nzira yekubatanidza zvinhu zvemagetsi kune akadhindwa edunhu mabhodhi nepamusoro Mount tekinoroji.Imwe nzira ndeyekubatanidza zvinhu zvemagetsi kuburikidza ne-buri mounting.
Motor basa re reflow soldering?
Iyo tembiricha yekushanda yereflow soldering yakakwira zvakanyanya, uye basa guru remota kutyaira vhiri remhepo kuti ribvise kupisa.
Ingani nzvimbo dzetembiricha ine reflow soldering ine?Kupisa kwakadini?Ndeipi nzvimbo yakakosha?
Chengyuan reflow soldering yakakamurwa kuita ina tembiricha nzvimbo zvinoenderana nebasa renzvimbo yekushisa: nzvimbo yekudziya, inogara tembiricha nzvimbo, solder zone, uye inotonhora nzvimbo.
Common reflow soldering pamusika inosanganisira sere tembiricha zone reflow soldering, nhanhatu tembiricha zone reflow soldering, gumi tembiricha zone reflow soldering, gumi nembiri tembiricha zone reflow soldering, gumi nemana tembiricha zone reflow soldering, nezvimwe. Izvi zvinogona kugadzirwa zvinoenderana nezvinodiwa nevatengi.Nekudaro, sere chete tembiricha zone reflow soldering yakajairika mumusika wehunyanzvi.Kune reflow soldering munzvimbo sere tembiricha, tembiricha yekumisikidza yenzvimbo yega yega tembiricha inonyanyoenderana neiyo solder paste uye chigadzirwa chinotengeswa.Basa renzvimbo imwe neimwe rakakosha zvikuru.Kazhinji kutaura, nzvimbo dzekutanga neyechipiri dzinoshandiswa senzvimbo dzekupisa, uye yechitatu neyechina shanu ndidzo nzvimbo dzekupisa.Constant tembiricha zone, 678 seye welding zone (inonyanya kukosha inzvimbo nhatu idzi), 8 nzvimbo dzinogona zvakare kushandiswa seyainobatsira nzvimbo yekutonhora, uye inotonhora nzvimbo, aya ndiwo musimboti, zvinofanirwa kutaurwa kuti mashoma. nzvimbo ndiyo kiyi, Hunhu hwechigadzirwa hunofanirwa kuvandudzwa, iyo nzvimbo ndiyo kiyi!
1. Preheating zone
Iyo preheating zone inopisa kusvika 175 madhigirii, uye nguva yacho inenge 100S.Zvinogona kuonekwa kubva pane izvi kuti chiyero chekupisa chenzvimbo yekupisa chinogona kuwanikwa (nekuti detector iyi inotora kuongororwa kwepamhepo, haina kupinda munzvimbo yekupisa kwechinguva kubva 0 kusvika 46S. , nguva 146-46 = 100S, sezvo tembiricha yemukati iri 26 madhigirii 175–26 = 149 madhigirii/100S=1.49 madhigirii/S)
2. Constant tembiricha zone
Iyo yakanyanya tembiricha munzvimbo yekushisa inogara yakatenderedza 200 madhigirii, iyo nguva ndeye 80 masekondi, uye mutsauko uripo pakati pekupisa kwakanyanya uye yakaderera tembiricha i25 madhigirii.
3. Reflow zone
Iyo yakanyanya tembiricha munzvimbo yekuyerera ndeye 245 madhigirii, yakaderera tembiricha ndeye 200 madhigirii, uye nguva yekusvika pakakwirira inenge 35/S;kupisa munzvimbo yekuyerera
Chiyero: 45 madhigirii/35S = 1.3 madhigirii/S Zvinoenderana ne (magadzirirwo etembiricha curve nemazvo), zvinogona kuoneka kuti nguva yekuti iyi tembiricha curve isvike kukosha kwepamusoro yakarebesa.Yese nguva yekudzokorora ndeye 60S
4. Kutonhora nzvimbo
Nguva iri munzvimbo yekutonhodza inenge 100S, uye tembiricha inodonha kubva pa245 degrees kusvika pa45 degrees.Kumhanya kwekutonhora ndiko: 245 madhigirii—45 madhigirii=200 madhigirii/100S=2 madhigirii/S
Nguva yekutumira: Jun-12-2023
