"Kev tu" yog feem ntau tsis quav ntsej hauv PCBA tsim cov txheej txheem ntawm Circuit Court cam, thiab nws yog kev tu kom huv tsis yog ib ruam tseem ceeb. Txawm li cas los xij, nrog kev siv ntev ntawm cov khoom lag luam sab, cov teeb meem tshwm sim los ntawm kev ua tsis tiav, kho cov khoom lag luam uas tau rov qab ua rau muaj kev ua haujlwm ntse. Hauv qab no, kev siv tshuab heming yuav qhia luv luv piav qhia txog lub luag haujlwm ntawm PCBA tu ntawm Circuit Court boards.
Cov txheej txheem ntau lawm ntawm PCBA (luam tawm cov txheej txheem Circuitand) mus los ntawm ntau theem txheej txheem, thiab cov theem muaj kuab paug rau lwm qib sib txawv. Yog li no, ntau qhov kev tso nyiaj los yog impurities nyob rau saum npoo ntawm Circuit Court Board PCBA. Cov kuab paug no yuav txo cov khoom lag luam, thiab txawm ua rau cov khoom tsis ua haujlwm. Piv txwv li, hauv cov txheej txheem ntawm soldering hluav taws xob Cheebtsam, cov cam pas tshuaj, flux, thiab lwm yam. Tom qab soldering, cov seem yog tsim. Cov seem muaj cov organic acids thiab ions. Ntawm lawv, organic acids yuav corrode cov Cirruit Coffe PCBA. Lub xub ntiag ntawm hluav taws xob ions yuav ua rau muaj kev luv luv ntawm Circuit Court thiab ua rau cov khoom poob.
Muaj ntau cov pa phem rau ntawm Circuit Court Board PCBA, uas tuaj yeem ua tau teev ua ob pawg: ionic thiab tsis yog ionic. Cov pa phem tau tuaj nrog noo noo nyob hauv ib puag ncig, thiab kev siv hluav taws xob, ua rau kev puas tsuaj ntawm lub PCBA ua haujlwm ntawm Circuit Coilcuit Board. Cov pa tsw qab no tuaj yeem txeem cov txheej insulating ntawm pc b thiab loj hlob dendrites nyob rau hauv lub pcb. Ntxiv rau Ionic thiab tsis yog-ionic cov pa paug, plua plav tuaj yeem ua rau muaj cov pob qij txha taub hau, thiab lwm yam cov pob qij txha ua kom tau txo qis, thiab cov pob qij txha sib dhos ntse Ntau yam tsis txaus ntseeg xws li pores thiab luv luv voj voog.
Nrog rau ntau cov pa paug, uas yog qhov kev txhawj xeeb tshaj plaws? Flux lossis ham muab tshuaj txhuam yog feem ntau siv hauv kev xav ua kom khov thiab yoj soldering txheej txheem. Lawv yog tsuas yog muaj xam nrog cov kuab tshuaj, cov chaw ntub dej sawv daws, cov resins, corrosion inhibitors thiab cov kev ua. Therify hloov kho yog khi rau muaj nyob tom qab soldering. Cov tshuaj ntawm cov khoom tsis ua hauj lwm, tom qab welding cov seem yog qhov tseem ceeb tshaj plaws cuam tshuam rau cov khoom zoo. Ionic cov seem yog qhov yuav ua rau hluav taws xob thiab txo cov rwb thaiv tsev tsis kam, thiab muaj mob hnyav, nws yuav ua rau qhib Circuit Court tsis ua haujlwm. Yog li, tu nruj me ntsis yuav tsum tau nqa tawm tom qab vuam los xyuas kom meej qhov zoo ntawm cov boardrcuit Court board pcba.
Hauv cov ntsiab lus, kev tu ntawm Circuit Court Board PCBA yog qhov tseem ceeb heev. "Tu" yog ib txoj kev tseem ceeb ncaj qha ntsig txog qhov zoo ntawm Circuit Court Board PCBA thiab yog qhov tseem ceeb.
