[Inner Circuit] cov ntawv ci tooj liab substrate yog thawj zaug txiav rau hauv qhov loj me uas haum rau kev ua thiab ntau lawm.Ua ntej substrate zaj duab xis nias, nws yog feem ntau yuav tsum tau roughen tooj liab ntawv ci ntawm lub phaj nto los ntawm txhuam hniav thiab micro etching, thiab ces muab cov qhuav zaj duab xis photoresist rau nws ntawm qhov tsim nyog kub thiab siab.Lub substrate pasted nrog qhuav zaj duab xis photoresist yog xa mus rau lub ultraviolet exposure tshuab rau raug.Lub photoresist yuav tsim cov tshuaj tiv thaiv polymerization tom qab raug irradiated los ntawm ultraviolet nyob rau hauv lub pob tshab cheeb tsam ntawm qhov tsis zoo, thiab cov kab duab ntawm qhov tsis zoo yuav raug xa mus rau qhuav zaj duab xis photoresist ntawm lub board nto.Tom qab rhuav tshem cov yeeb yaj kiab tiv thaiv ntawm lub ntsej muag zaj duab xis, txhim kho thiab tshem tawm qhov tsis pom kev ntawm qhov chaw ntawm zaj duab xis nrog sodium carbonate aqueous tov, thiab tom qab ntawd corrode thiab tshem tawm cov ntawv ci tooj liab nrog hydrogen peroxide tov los tsim ib lub voj voog.Thaum kawg, photoresist ntawm zaj duab xis qhuav raug tshem tawm los ntawm lub teeb sodium oxide aqueous tov.
[Nias] sab hauv lub rooj tsav xwm tom qab ua tiav yuav tsum tau ua tiav nrog lub voj voog sab nrauv tooj liab ntawv nrog iav fiber ntau zaj duab xis.Ua ntej nias, lub phaj sab hauv yuav tsum tau blackened (oxygenated) kom passivate tooj liab nto thiab nce lub rwb thaiv tsev;Cov tooj liab nto ntawm sab hauv Circuit Court yog coarsened los tsim zoo adhesion nrog zaj duab xis.Thaum sib tshooj, lub rooj tsav xwm sab hauv uas muaj ntau tshaj li rau txheej (nrog rau) yuav tsum tau riveted ua khub nrog lub tshuab riveting.Tom qab ntawd muab tso rau hauv nruab nrab ntawm daim iav steel daim hlau nrog lub phaj tuav, thiab xa mus rau lub tshuab nqus tsev xovxwm kom tawv thiab khi cov zaj duab xis nrog qhov kub thiab txias.Lub hom phiaj lub qhov ntawm lub rooj tsavxwm pressed yog drilled los ntawm X-ray tsis siv neeg qhov chaw lub hom phiaj drilling tshuab raws li qhov siv lub qhov rau kev sib raug zoo ntawm sab hauv thiab sab nraud circuits.Lub phaj ntug yuav tsum raug txiav kom zoo kom yooj yim rau kev ua haujlwm tom ntej.
[Drilling] laum lub rooj tsav xwm hauv Circuit Court nrog CNC drilling tshuab rau laum los ntawm lub qhov ntawm interlayer Circuit Court thiab kho qhov ntawm vuam qhov chaw.Thaum drilling, siv tus pin los txhim kho lub rooj tsav xwm hauv lub rooj sib tham ntawm lub tshuab drilling los ntawm lub qhov uas twb tau drilled lub hom phiaj, thiab ntxiv ib lub phaj qis qis (phenolic ester phaj lossis ntoo pulp phaj) thiab lub phaj npog sab sauv (aluminium phaj) kom txo tau. qhov tshwm sim ntawm drilling burrs.
[Plated Through Hole] tom qab lub interlayer conduction channel yog tsim, ib txheej hlau tooj liab yuav tsum tau teem rau ntawm nws kom ua tiav cov txheej txheem ntawm interlayer circuit.Ua ntej, ntxuav cov plaub hau ntawm lub qhov thiab cov hmoov hauv lub qhov los ntawm kev sib tsoo hnyav thiab kev siv lub zog siab, thiab tsau thiab muab tin rau ntawm phab ntsa ntxuav lub qhov.
[Pib Copper] palladium colloidal txheej, thiab tom qab ntawd nws raug txo rau hlau palladium.Lub Circuit Court board yog immersed nyob rau hauv ib tug tshuaj tooj liab tov, thiab tooj liab ion nyob rau hauv cov kev daws yog txo thiab tso rau ntawm lub qhov phab ntsa los ntawm lub catalysis ntawm palladium hlau los ua ib tug dhau-lub qhov Circuit Court.Tom qab ntawd, cov txheej tooj liab nyob rau hauv lub qhov yog thickened los ntawm tooj liab sulfate da dej electroplating mus rau ib tug tuab txaus los tiv thaiv cov kev cuam tshuam ntawm kev ua tom qab thiab kev pab cuam ib puag ncig.
[Outer Line Secondary Copper] kev tsim cov duab hloov pauv yog zoo li cov kab sab hauv, tab sis hauv kab etching, nws tau muab faib ua txoj hauv kev zoo thiab tsis zoo.Txoj kev tsim cov yeeb yaj kiab tsis zoo yog zoo li cov khoom tsim tawm hauv Circuit Court.Nws yog ua tiav los ntawm ncaj qha etching tooj liab thiab tshem tawm zaj duab xis tom qab kev loj hlob.Txoj kev tsim cov yeeb yaj kiab zoo yog ntxiv cov tooj liab thiab tin txhuas plating tom qab kev txhim kho (cov tin txhuas nyob rau hauv cheeb tsam no yuav khaws cia raws li kev tiv thaiv etching nyob rau tom qab tooj liab etching kauj ruam).Tom qab tshem tawm cov yeeb yaj kiab, cov ntawv ci tooj liab raug corroded thiab tshem tawm nrog alkaline ammonia thiab tooj liab chloride tov tov los tsim ib txoj hauv kev.Thaum kawg, siv cov tin txhuas stripping tov kom tev tawm cov tin txhuas txheej uas tau ua tiav cov nyiaj laus (thaum ntxov, cov tin txhuas txheej tau khaws cia thiab siv los qhwv lub voj voog raws li txheej tiv thaiv tom qab rov yaj, tab sis tam sim no nws yog feem ntau. tsis siv).
[Anti Welding Ink Text Printing] cov xim ntsuab thaum ntxov yog tsim los ntawm cov cua sov ncaj qha (lossis ultraviolet irradiation) tom qab tshuaj ntsuam luam ntawv kom tawv xim zaj duab xis.Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm kev luam ntawv thiab hardening, nws feem ntau ua rau cov xim ntsuab nkag mus rau hauv cov tooj liab ntawm cov kab hluav taws xob sib txuas, uas ua rau muaj teeb meem ntawm qhov vuam thiab siv.Tam sim no, ntxiv rau kev siv cov kab hluav taws xob yooj yim thiab ntxhib, lawv feem ntau yog tsim nrog cov xim ntsuab photosensitive.
Cov ntawv nyeem, cov cim lag luam lossis tus lej yuav tsum tau los ntawm cov neeg siv khoom yuav tsum tau luam tawm ntawm lub rooj tsavxwm los ntawm kev tshuaj ntsuam luam ntawv, thiab tom qab ntawd cov ntawv xim xim yuav tsum tau ua kom tawv tawv los ntawm kev ziab kub (lossis ultraviolet irradiation).
[Kev Sib Txuas Lus] Kev tiv thaiv welding ntsuab xim npog feem ntau ntawm cov tooj liab ntawm lub voj voog, thiab tsuas yog cov kev sib txuas ntawm lub davhlau ya nyob twg rau ib feem vuam, kev ntsuas hluav taws xob thiab cov khoom siv hluav taws xob hauv Circuit Court.Cov txheej txheem tiv thaiv tsim nyog yuav tsum tau ntxiv rau qhov kawg taw tes no kom tsis txhob muaj oxide tiam ntawm qhov kawg taw tes txuas anode (+) hauv kev siv mus sij hawm ntev, cuam tshuam rau Circuit Court stability thiab ua rau muaj kev txhawj xeeb txog kev nyab xeeb.
[Moulding Thiab Txiav] txiav lub rooj tsav xwm hauv Circuit Court rau sab nraud qhov ntev yuav tsum tau los ntawm cov neeg siv khoom nrog CNC molding tshuab (los yog tuag punch).Thaum txiav, siv tus pin los txhim kho lub rooj tsav xwm hauv lub txaj (lossis pwm) los ntawm qhov chaw ua haujlwm yav dhau los.Tom qab txiav, tus ntiv tes golden yuav tsum tau muab txiav rau ntawm lub kaum sab xis kom yooj yim rau kev ntxig thiab siv lub rooj tsav xwm hauv Circuit Court.Rau lub rooj tsav xwm Circuit Court uas tsim los ntawm ntau lub chips, X-shaped break kab yuav tsum tau ntxiv los pab cov neeg siv khoom sib cais thiab disassemble tom qab lub plug-in.Thaum kawg, ntxuav cov plua plav ntawm lub rooj tsavxwm Circuit Court thiab cov pa phem ionic ntawm qhov chaw.
[Kev Tshuaj Ntsuam Xyuas Cov Ntim] Ntim Ntim: PE zaj duab xis ntim, ntim zaj duab xis tshav kub, ntim ntim, thiab lwm yam.
