Dab tsi yog PCBA Kev Tshuaj Ntsuam Xyuas Kev Nyab Xeeb?

Kev kuaj pom kev

Siv lub iav magnifying (X5) los yog optical microscope rau PCBA, qhov zoo ntawm kev ntxuav yog soj ntsuam los ntawm kev soj ntsuam lub xub ntiag ntawm cov khoom seem ntawm solder, dross thiab tin hlaws dai, unfixed hlau hais thiab lwm yam kab mob.Nws yog feem ntau yuav tsum tau hais tias PCBA nto yuav tsum huv si li sai tau thiab kom tsis txhob muaj ib tug seem ntawm residues los yog cov kab mob yuav tsum tau pom.Qhov no yog qhov ntsuas tau zoo thiab feem ntau yog tsom rau ntawm tus neeg siv cov kev xav tau, lawv tus kheej cov txheej txheem kev txiav txim siab thiab tus naj npawb ntawm cov magnifications siv thaum lub sijhawm tshuaj xyuas.Txoj kev no yog tus cwj pwm los ntawm nws txoj kev yooj yim thiab yooj yim ntawm kev siv.Qhov tsis zoo yog tias nws tsis tuaj yeem kuaj xyuas cov kab mob hauv qab ntawm cov khoom siv thiab cov khoom seem ionic thiab tsim nyog rau kev thov tsawg dua.

Txheej Txheem Extraction

Txoj kev tshem tawm cov kuab tshuaj kuj tseem hu ua ionic contaminant content test.Nws yog ib hom ionic contaminant cov ntsiab lus ntsuas nruab nrab, qhov kev ntsuam xyuas feem ntau yog siv IPC txoj kev (IPC-TM-610.2.3.25), nws yog ntxuav PCBA, raus rau hauv ionic degree contamination tester tov (75% ± 2% ntshiab isopropyl. cawv ntxiv 25% DI dej), cov ionic residue yuav yaj nyob rau hauv cov kuab tshuaj, ua tib zoo sau cov kuab tshuaj, txiav txim siab nws resistivity

Cov kab mob ionic feem ntau yog muab los ntawm cov khoom siv ntawm cov khoom siv, xws li halogen ions, acid ions, thiab hlau ions los ntawm corrosion, thiab cov txiaj ntsig tau qhia raws li tus naj npawb ntawm sodium chloride (NaCl) sib npaug hauv ib cheeb tsam.Ntawd yog, tag nrho cov nyiaj ntawm cov kab mob ionic no (xws li tsuas yog cov uas tuaj yeem yaj hauv cov kuab tshuaj) yog sib npaug ntawm NaCl, tsis tas li los yog tsuas yog muaj nyob rau saum npoo ntawm PCBA.

Surface Insulation Resistance Test (SIR)

Txoj kev no ntsuas qhov rwb thaiv tsev tiv thaiv ntawm cov conductors ntawm PCBA.Kev ntsuas ntawm qhov hluav taws xob rwb thaiv tsev qhia tau hais tias xau vim kev sib kis nyob rau hauv ntau yam kub, av noo, voltage thiab lub sijhawm.Qhov zoo yog kev ntsuas ncaj qha thiab muaj nuj nqis;thiab lub xub ntiag ntawm thaj chaw hauv cheeb tsam ntawm solder paste tuaj yeem kuaj pom.Raws li cov residual flux nyob rau hauv PCBA solder paste yog tam sim no nyob rau hauv lub seam ntawm lub ntaus ntawv thiab lub PCB, tshwj xeeb tshaj yog nyob rau hauv solder pob qij txha ntawm BGAs, uas yog nyuaj rau tshem tawm, thiaj li yuav ntxiv mus xyuas cov nyhuv tu, los yog xyuas kom meej qhov kev nyab xeeb. (kev ua haujlwm hluav taws xob) ntawm cov khoom siv tshuaj siv, kev ntsuas ntawm qhov chaw tiv thaiv nyob rau hauv seam nruab nrab ntawm cov khoom thiab PCB feem ntau yog siv los kuaj xyuas cov nyhuv ntawm PCBA.

Qhov kev ntsuas SIR dav dav yog 170 teev ntsuas ntawm 85 ° C ambient kub, 85% RH ambient humidity thiab 100V ntsuas kev tsis ncaj ncees.
