39-xyoo-laus "welder" Wang Nws muaj ob txhais tes tshwj xeeb dawb thiab muag heev.Nyob rau hauv 15 xyoo dhau los, ob txhais tes txawj ntse no tau koom nrog hauv kev tsim khoom ntawm ntau tshaj 10 qhov chaw thauj khoom, suav nrog cov npe nrov Shenzhou, Tiangong series thiab Chang'e series.
Wang Nws yog ib tug neeg ua haujlwm ntawm Denso Technology Center ntawm Changchun Institute of Optics, Fine Mechanics thiab Physics, Suav Academy ntawm Sciences.Txij li xyoo 2006, nws tau koom nrog aerospace PCB phau ntawv vuam.Yog tias qhov vuam zoo tib yam piv rau "saws khaub ncaws", nws txoj haujlwm tuaj yeem hu ua "paj ntaub".
"Puas yog cov txhais tes tshwj xeeb khaws cia kom ua tau zoo thiab yoog raws?"Thaum nug los ntawm tus kws sau xov xwm, Wang Nws pab tsis tau tab sis luag ntxhi: "Aerospace cov khoom muaj cov kev cai nruj heev.Peb ua haujlwm nyob rau hauv qhov kub thiab av noo ib puag ncig tau ntau xyoo, thiab peb feem ntau ua haujlwm tshaj sijhawm.Kuv tsis muaj sijhawm los ua haujlwm hauv tsev, kuv cov tawv nqaij yog qhov ncaj ncees thiab sib tw. "
Suav lub npe ntawm PCB yog luam tawm lub rooj tsavxwm, uas yog kev txhawb nqa ntawm cov khoom siv hluav taws xob, ib yam li "lub hlwb" ntawm lub dav hlau, phau ntawv soldering yog solder cov khoom rau lub rooj tsavxwm.
Wang He hais rau cov neeg sau xov xwm tias thawj lub ntsiab lus ntawm cov khoom siv dav hlau yog "kev ntseeg siab."Feem ntau ntawm cov khoom siv yog kim, thiab qhov yuam kev me me hauv kev ua haujlwm yuav ua rau ntau pua lab nyiaj poob rau hauv kev poob.
Wang He tau xyaum "paj ntaub" zoo heev, thiab tsis muaj ib qho ntawm ze li ib lab cov pob qij txha uas nws tau ua tiav yog tsis tsim nyog.Tus kws tshuaj ntsuam xyuas tau hais tias: "Txhua tus ntawm nws cov pob qij txha yog qhov zoo rau qhov muag."
Nrog nws lub peev xwm ua lag luam zoo heev thiab muaj lub luag haujlwm siab, Wang Nws ib txwm sawv ntawm lub sijhawm tseem ceeb.
Ib zaug, txoj haujlwm ntawm qee tus qauv tau nruj, tab sis qee cov khoom hauv Circuit Court board muaj qhov tsis zoo tsim, uas tsis tso chaw txaus rau kev ua haujlwm.Wang Nws tau ntsib cov teeb meem thiab tso siab rau qhov tseeb ntawm tes kom ua tiav tag nrho cov vuam.
Nyob rau lwm lub sijhawm, vim yog tus neeg ua haujlwm yuam kev hauv qee yam qauv ua haujlwm, ntau lub PCB pads poob tawm, thiab ntau lab yuan cov cuab yeej tau ntsib cov khoom seem.Wang He tau pib nug Ying.Tom qab ob hnub thiab ob hmo ntawm kev ua haujlwm hnyav, nws tau tsim cov txheej txheem kho tshwj xeeb thiab kho sai sai rau PCB kom zoo, uas tau qhuas heev.
Xyoo tas los, Wang Nws raug mob nws lub qhov muag ntawm kev ua haujlwm thiab nws qhov muag tsis pom kev, yog li nws yuav tsum tau hloov mus rau kev cob qhia.
Txawm hais tias nws tsis tuaj yeem koom nrog hauv txoj haujlwm ntawm txoj kab pem hauv ntej, nws tsis muaj kev khuv xim: "Ib tug neeg lub peev xwm raug txwv, thiab kev loj hlob ntawm Tuam Tshoj txoj kev lag luam aerospace yuav tsum tau suav tes ua khub.Kuv tau tibneeg hu tauj coob nrog kev ua haujlwm yav dhau los, thiab kuv tsuas tuaj yeem nqa ib tus neeg ua haujlwm xwb, thiab tam sim no kuv tuaj yeem dhau ntau xyoo dhau los.Txhawm rau pab ntau tus neeg thiab ua kom paub ntau ntxiv.
