Muaj ob txoj hauv kev tseem ceeb ntawm kev lag luam soldering - reflow thiab yoj soldering.
Wave soldering cuam tshuam nrog kev hla dhau ntawm lub rooj tsavxwm preheated.Board kub, cua sov thiab cua txias profiles (non-linear), soldering kub, waveform (uniform), solder lub sij hawm, txaus tus nqi, board tshaj tawm, thiab lwm yam yog tag nrho cov tseem ceeb uas cuam tshuam rau soldering tau.Txhua yam ntawm board tsim, layout, ncoo puab thiab loj, tshav kub dissipation, thiab lwm yam yuav tsum tau ua tib zoo xav txog qhov zoo soldering.
Nws yog tseeb tias yoj soldering yog ib qho kev txhoj puab heev thiab xav tau - yog li vim li cas siv cov txheej txheem no txhua?
Nws yog siv vim nws yog txoj kev zoo tshaj plaws thiab pheej yig tshaj plaws uas muaj, thiab qee zaum tsuas yog siv txoj hauv kev xwb.Qhov twg los ntawm lub qhov yog siv, yoj soldering feem ntau yog txoj kev xaiv.
Reflow soldering yog hais txog kev siv cov tshuaj txhuam hniav (ib qho sib xyaw ntawm cov khoom siv thiab cov khoom siv hluav taws xob) los txuas ib lossis ntau cov khoom siv hluav taws xob rau cov ntaub so ntswg, thiab yaj lub solder los ntawm kev tswj cua sov kom ua tiav kev sib txuas mus tas li.Reflow ncu yuav siv tau, infrared cua sov teeb los yog cua sov phom thiab lwm yam cua sov txoj kev rau vuam.Reflow soldering muaj qhov yuav tsum tau tsawg dua ntawm cov ntaub qhwv ntsej muag, shading, board orientation, qhov kub thiab txias (tseem ceeb heev), thiab lwm yam. Rau cov khoom siv saum npoo av, feem ntau yog ib qho kev xaiv zoo heev - solder thiab flux sib tov yog ua ntej siv los ntawm stencil lossis lwm yam. automated txheej txheem, thiab cov khoom yog muab tso rau hauv qhov chaw thiab feem ntau tuav nyob rau hauv qhov chaw los ntawm solder paste.Adhesives tuaj yeem siv rau hauv cov xwm txheej xav tau, tab sis tsis haum nrog cov khoom hauv lub qhov - feem ntau reflow tsis yog txoj kev xaiv rau ntawm qhov chaw.Composite los yog high-density boards siv tau ib tug sib tov ntawm reflow thiab yoj soldering, tsuas yog cov leaded qhov chaw mounted rau ib sab ntawm lub PCB (hu ua sab A), ces lawv yuav yoj soldered rau sab B. Qhov twg TH ib feem yog rau yuav tsum tau muab tso ua ntej lub qhov los ntawm qhov muab tso, cov khoom yuav tsum tau reflowed rau sab A.Ntxiv SMD qhov chaw tuaj yeem muab ntxiv rau sab B kom yoj soldered nrog TH qhov chaw.Cov neeg mob siab rau siab hlau soldering tuaj yeem sim cov sib tov sib xyaw ntawm cov sib txawv melting point solders, cia sab B reflow ua ntej lossis tom qab yoj soldering, tab sis qhov no tsis tshua muaj heev.
Reflow soldering tshuab yog siv rau saum npoo mount qhov chaw.Txawm hais tias feem ntau cov mount Circuit Court boards tuaj yeem sib sau ua ke los ntawm tes siv cov hlau thiab cov hlau nplaum, cov txheej txheem qeeb thiab cov txiaj ntsig tau tuaj yeem tsis ntseeg.Niaj hnub nimno PCB sib dhos khoom siv reflow soldering tshwj xeeb tshaj yog rau cov khoom loj, qhov chaw tuaj tos-thiab-chaw machines tso cov khoom ntawm cov laug cam, uas yog coated nrog solder paste, thiab tag nrho cov txheej txheem yog automated.
