Nyob rau hauv lub ntiaj teb niaj hnub no tau tsav los ntawm cov khoom siv hluav taws xob, los ntawm cov xov tooj smartphones mus rau lub dav hlau, "lub siab" ntawm txhua lub cuab yeej ntse yog lub rooj tsav xwm hauv Circuit Court uas muaj qhov sib txawv. Zoo li lub nroog daim phiaj xwm, nws txuas ntau yam khoom siv hluav taws xob, tsim "txoj kev loj" rau cov ntaub ntawv ntws. Kev tsim hluav taws xob Circuit Court yog ib qho kev ua haujlwm siab - thev naus laus zis uas ua ke nrog cov ntaub ntawv science, chemistry, optics, thiab precision mechanics. Nws cov txheej txheem nruj thiab nyuaj yog daim duab kos duab tiag tiag hauv kev tsim khoom.
Circuit Board manufacturing pib nrog nws cov core substrate-tooj liab-clad laminate (CCL). Lub tiaj tiaj insulating board, feem ntau yog ua los ntawm fiberglass epoxy resin, muaj ib txheej nyias ntawm cov ntawv ci tooj liab ruaj khov rau nws qhov chaw. Daim ntawv tooj liab no yuav tsim cov qauv ntawm txhua lub voj voog yav tom ntej.
Kauj Ruam 1: Hloov duab duab-Pib daim ntawv qhia rau tooj liab
Ua ntej, engineers siv lub computer- pab tsim software los tsim cov duab kos, uas yog tom qab ntawd tso tawm kom siab - cov yeeb yaj kiab uas siv lub laser plotter. Hauv chav huv, qhov chaw ntawm CCL yog coated nrog UV-sensitive photoresist. Tom qab ntawd, zaj duab xis muab tso rau ntawm lub rooj tsavxwm zoo li cov duab thaij duab thiab raug UV teeb. Cov cheeb tsam raug rau lub teeb raug tshuaj lom neeg cov tshuaj tiv thaiv. Tom qab tau ntxuav nrog kev tsim kho, daim duab kos duab tau khaws cia kom meej meej ntawm lub rooj tsavxwm- cov chaw uas cov ntawv ci tooj liab yuav tsum tau khaws cia yog kev tiv thaiv los ntawm photoresist, thaum cov cheeb tsam yuav tsum tau etched tawm. Cov txheej txheem no zoo li tus kws yees duab tsim cov duab hauv chav tsaus, hloov cov qauv tsim tsis pom kev rau hauv cov txheej txheem tiv thaiv tangible.
Theem Thib Ob: Tshuaj Etching-Sculpting the Circuit's intricacies
Tom ntej no, lub rooj tsavxwm nkag mus rau hauv etching ntau lawm kab. Raws li kev tswj hwm nruj, lub rooj tsavxwm dhau los ntawm lub tank etching qhov twg cov tshuaj muaj zog ua kom yaj tag nrho cov ntawv ci tooj liab tsis tiv thaiv los ntawm photoresist. Tom qab cov txheej txheem no, intricate, plaub hau- nyias cov qauv Circuit Court tshwm sim los ntawm cov ntawv ci tsis zoo. Tom qab ntawd, qhov kev tiv thaiv photoresist raug tshem tawm, thiab ib qho qauv tsim hluav taws xob uas ua rau tus neeg tsim kev txawj ntse tau yug los. Lub precision ntawm etching ncaj qha txiav txim siab qhov ua tau zoo ntawm lub rooj tsavxwm Circuit Court; nws yuav tsum xyuas kom meej cov kab sib xws, tsis muaj burrs, thiab tsis muaj tooj liab seem.
Theem Thib Peb: Lamination thiab Drilling-Tsim peb-Dimensional Interconnected World
Rau complex multilayer boards, cov txheej txheem tsim yog txawm ntau intricate. Ntau lub cores nrog etched inner txheej circuitry yog stacked alternately nrog prepregs, zoo li tsim ib mille -feuille ncuav mog qab zib. Nyob rau hauv lub siab - kub, siab - siab laminator, lawv raug nias ua ke rau hauv ib qho khoom tag nrho. Tom qab ntawd, lub siab - precision CNC drilling tshuab, raws li cov ntaub ntawv kev pab cuam, xyaum ntau txhiab micro- qhov rau hauv lub rooj tsavxwm. Cov qhov no yuav raug siv los txuas circuits ntawm cov txheej txheem sib txawv.
Lub qhov phab ntsa tom qab drilling yog insulating thiab yuav tsum tau conductive. Qhov no yog ua tiav los ntawm cov txheej txheem tshuaj tooj liab plating: ib txheej nyias ntawm cov tshuaj tooj liab tso rau ntawm lub qhov phab ntsa kom metallize lawv. Tom qab ntawd, cov txheej tooj liab ntawm cov phab ntsa ntawm lub qhov thiab cov kab hluav taws xob saum npoo yog thickened los ntawm electroplating kom ntseeg tau cov kev sib txuas txhim khu kev qha thiab muaj peev xwm nqa tau tam sim no.
Kauj Ruam Plaub: Solder Mask thiab Silkscreen Printing - Thaum kawg Kev Tiv Thaiv thiab Kev Txheeb Xyuas
Txhawm rau tiv thaiv cov khoom siv hluav taws xob tsis zoo los ntawm oxidation, kev sib kis, thiab kev puas tsuaj rau lub cev, thiab tiv thaiv luv luv Circuit Court thaum soldering, Circuit Court board yuav tsum tau coated nrog ib txheej ntawm solder mask number case. Feem ntau ntsuab, tus cwj mem no yog siv los ntawm kev nthuav tawm thiab kev loj hlob, nthuav tawm tsuas yog cov ntaub qhwv uas yuav tsum tau soldered. Thaum kawg, ib txheej silkscreen dawb yog luam tawm ntawm lub rooj tsavxwm saum npoo los cim cov khoom siv siv tus qauv tsim, polarities, thiab cov ntaub ntawv tsim khoom, muab cov lus qhia meej rau cov khoom sib dhos tom ntej.
Xaus
Los ntawm kev tsim qauv kos duab mus rau lub rooj tsav xwm ua haujlwm tag nrho, cov txheej txheem tsim khoom yog ib qho kev ua las voos uas cuam tshuam txog physics thiab chemistry. Txhua kauj ruam yuav tsum tau ua kom huv huv heev, tswj cov txheej txheem meej, thiab kev tshuaj xyuas nruj heev. Nws yog qhov yuav luag xav tau kev kos duab ntawm kev tsim khoom uas muab lub neej thiab kev txawj ntse rau lub teeb yuag tsis tau muaj zog hluav taws xob hauv peb txhais tes, ntsiag to txhawb kev ua haujlwm nrawm ntawm lub neej niaj hnub.
