Nyob rau hauv cov khoom siv hluav taws xob, hluav taws xob midochemical (ECM) feem ntau hu ua tus kab mob sib txawv, thiab tseem muaj kev cuam tshuam rau kev ua kom luv heev, thiab cov kev cuam tshuam loj heev thiab av noo .
{{0 {}} Dab tsi yog Electrochemical tsiv teb tsaws (ECM)?
ECM yog kev thauj khoom ntawm cov hlau i / tin, cov nyiaj, thiab muab tso rau hauv ib qho:} Cov txheej txheem nthuav tawm hauv peb theem:
- Electroly ntawm anode hlau rau hauv ions (e {{{} g}}! → → .
- Tsiv teb tsaws ntawm cov ions los ntawm insulating nruab nrab hauv qab ib qho siv hluav taws xob teb .
- Kev Txhim Kho Kev Loj Hlob: Lub ions tau txo rov qab mus rau hlau ntawm lub catting, tsob ntoo ntoo zoo li cov pathways uas tuaj yeem thaum kawg Choj npe .
ECM yog nquag pom thaum lub siab kub, high elality kev cia siab rau BGA thiab H3trb, qhov twg yog qhov chaw me me ua luv luv ntau dua.
{2. cov xwm txheej uas txhawb nqa ECM
- Vaum: Rh> 80% ua cov yeeb yaj kiab dej adsorbed uas ua raws li electrolyte thiab accelerates ion thauj ol6.
-Txhais kev sib txawv: DC kev tsis ncaj ncees ntawm cov neeg saib xyuas (e. pa taws sib koom tes hluav taws xob thiab lub zog tsav rau tsiv teb tsaws.
- Ionic kev sib kis: residual flux, plua plav, lossis lwm yam paug muab cov khoom tsis zoo rau ECM .
{{05. Kev Tiv Thaiv Tiv Thaiv Dav Hlau: Ua txhaum "txoj kev ciaj sia taus" ntawm ECM
- Kev tswj hwm ib puag ncig
- Txo cov av noo los ntawm cov txheej txheem ua piv txwv lossis cov potting|.
- Saib xyuas cov khoom siv hauv qab 60% rh .
- Tsim Txhim Kho Kom Zoo
- nce cov neeg coj ua thiab txo cov pob zeb me me hauv cov iav-fiber laminates (hais caf).
- Zam kev sib txawv ntawm cov dc loj loj ntawm qhov sib txawv ntawm cov uas nyob ze .
- Xaiv CAF-resistant pcb cov ntaub ntawv .
- Txhim Kho Cov Txheej Txheem
- txhim kho tu kom tshem tawm cov ionic seem .
- txhim kho soldering zoo kom tiv thaiv micro-tawg .
- Cov khoom siv xaiv
- Siv cov av noo-nqus-nqus cov kev ua haujlwm thiab hlau ua tiav uas tiv thaiv ion tsiv teb chaws.
Grgtest yog ib qho ntawm Tuam Tshoj qhov feem ntau pom tias muaj kev ntsuas tus neeg thib peb, GREGAs-confenction suplement circuacts thiab kev pabcuam zoo tshaj plaws thoob plaws tag nrho cov semiconductor Cov khoom siv saw .
