Nzira yekuongorora yekuona
Kushandisa girazi rinokudza (X5) kana microscope yemaziso kuPCBA, kunaka kwekuchenesa kunoongororwa nekucherechedza kuvapo kwezvisara zvakasimba zve solder, marara nemarata, zvidimbu zvesimbi zvisina kumira uye zvimwe zvinosvibisa.Zvinowanzodikanwa kuti nzvimbo yePCBA inofanira kuva yakachena sezvinobvira uye kuti hapana zvisaririra zvezvisaririra kana zvinosvibisa zvinofanira kuonekwa.Ichi chiratidzo chehunhu uye chinowanzo tariswa pane zvinodiwa nemushandisi, yavo yekuyedza kutonga maitiro uye huwandu hwehukuru hunoshandiswa panguva yekuongorora.Iyi nzira inoratidzirwa nekureruka kwayo uye nyore kushandisa.Izvo zvakashata ndezvekuti hazvigoneke kutarisa kune zvinosvibisa pasi pezvikamu uye zvakasara zveionic zvinosvibisa uye inokodzera zvikumbiro zvisinganyanyi kudiwa.
Solvent Extraction Method
Iyo yekunyungudutsa yekubvisa nzira inozivikanwawo seiyo ionic inosvibisa yemukati bvunzo.Imhando yeionic inosvibisa mukati meavhareji bvunzo, bvunzo inowanzo shandiswa IPC nzira (IPC-TM-610.2.3.25), inocheneswa PCBA, yakanyudzwa muiyo ionic degree kusvibiswa tester test solution (75% ± 2% pure isopropyl. doro pamwe ne25% DI mvura), iyo ionic yakasara ichanyungudutswa mune inonyungudutsa, nyatso unganidza iyo inonyungudutsa, sarudza iyo resistivity.
Ionic inosvibisa inowanzo torwa kubva kune inoshanda zvinhu zve solder, senge halogen ions, acid ions, uye simbi ions kubva mukuora, uye mhedzisiro inoratidzwa senhamba ye sodium chloride (NaCl) yakaenzana pane imwe unit nzvimbo.Ndiko kuti, huwandu hwose hweionic inosvibisa (inosanganisira chete iyo inogona kunyungudutswa mu solvent) yakaenzana nehuwandu hweNaCl, kwete hazvo kana kuti huripo chete pamusoro pePCBA.
Surface Insulation Resistance Test (SIR)
Iyi nzira inoyera iyo yekumusoro insulation kuramba pakati conductors paPCBA.Chiyero chekudzivirira kwekudzivirira kwepasi chinoratidza kuvuza nekuda kwekusvibiswa pasi pemamiriro akasiyana ekushisa, humidity, voltage uye nguva.Zvakanakira kuyera kwakananga uye kuwanda;uye kuvapo kwenzvimbo dzenzvimbo dze solder paste inogona kuonekwa.Sezvo iyo yakasara inoyerera muPCBA solder paste inonyanya kuvepo musono pakati pechishandiso nePCB, kunyanya mumajoini anotengeswa eBGAs, ayo akanyanya kuoma kubvisa, kuitira kuenderera mberi nekuongorora mhedzisiro yekuchenesa, kana kuona kuchengetedzwa. (yemagetsi kuita) kweiyo solder paste inoshandiswa, kuyerwa kwekupokana kwepasi mumusono pakati pechikamu nePCB kunowanzo shandiswa kutarisa kuchenesa maitiro ePCBA.
Mamiriro ezvinhu ekuyera kweSIR ndeye 170 awa bvunzo pa85 ° C ambient tembiricha, 85% RH ambient humidity uye 100V kuyerwa kwakarerekera.
