Hauv PCB pov thawj, ib txheej ntawm cov hlau lead-tin tiv thaiv yog pre-plated rau ntawm cov ntawv ci tooj liab yuav tsum tau khaws cia rau ntawm txheej txheej ntawm lub rooj tsavxwm, uas yog, cov duab kos duab ntawm lub voj voog, thiab tom qab ntawd cov ntawv nyiaj seem tooj liab yog tshuaj etched. deb, uas yog hu ua etching.
Yog li, hauvPCB pov thawj, cov teeb meem dab tsi yuav tsum tau them nyiaj rau hauv etching?
Qhov kev xav tau zoo ntawm etching yog kom tshem tawm tag nrho cov txheej tooj liab tag nrho tsuas yog nyob rau hauv cov txheej txheem etching.Hais lus nruj me ntsis, etching zoo yuav tsum muaj xws li cov uniformity ntawm cov hlau dav thiab cov degree ntawm sab etching.
Qhov teeb meem ntawm sab etching yog feem ntau tsa thiab tham hauv etching.Qhov piv ntawm sab etch dav rau etch qhov tob yog hu ua etch factor.Hauv kev lag luam luam tawm, qhov me me sab etch degree lossis qhov qis etch yog qhov txaus siab tshaj plaws.Cov qauv ntawm cov khoom siv etching thiab qhov sib txawv ntawm cov tshuaj etching yuav cuam tshuam rau etching yam lossis sab etching degree.
Nyob rau hauv ntau txoj kev, qhov zoo ntawm etching tshwm sim ntev ua ntej lub Circuit Court board nkag mus rau hauv lub tshuab etching.Vim tias muaj kev sib raug zoo sab hauv ntawm ntau yam txheej txheem ntawm PCB pov thawj, tsis muaj txheej txheem uas tsis cuam tshuam los ntawm lwm cov txheej txheem thiab tsis cuam tshuam rau lwm cov txheej txheem.Ntau qhov teeb meem uas tau txheeb xyuas tias qhov zoo ntawm etch yeej muaj nyob rau hauv cov txheej txheem stripping txawm tias ua ntej.
Kev hais lus theoretical, PCB pov thawj nkag mus rau theem etching.Nyob rau hauv cov qauv electroplating txoj kev, lub zoo tagnrho lub xeev yuav tsum yog: lub sum ntawm lub thickness ntawm tooj liab thiab txhuas tin tom qab electroplating yuav tsum tsis txhob tshaj lub thickness ntawm cov electroplating photosensitive zaj duab xis, thiaj li hais tias cov electroplating qauv yog kiag li them rau ob sab ntawm cov zaj duab xis.Cov "phab ntsa" blocks thiab muab tso rau hauv nws.Txawm li cas los xij, hauv kev tsim khoom tiag tiag, cov qauv txheej txheej yog tuab dua li cov qauv photosensitive;Txij li thaum qhov siab ntawm cov txheej txheej tshaj li cov yeeb yaj kiab photosensitive, muaj qhov sib txawv ntawm cov khoom sib txuas sab nraud, thiab cov tin lossis cov hlau lead-tin tiv thaiv txheej npog saum cov kab txuas mus rau ob sab, tsim ib qho "Edge", ib feem me me ntawm cov yeeb yaj kiab photosensitive. yog npog hauv qab "ntug".Lub "ntug" tsim los ntawm tin los yog txhuas-tin ua rau nws tsis yooj yim sua kom tshem tawm cov yeeb yaj kiab photosensitive thaum tshem cov yeeb yaj kiab, tawm hauv ib feem me me ntawm "kua nplaum" nyob rau hauv "ntug", uas ua rau tsis tiav etching.Cov kab tsim "cov cag tooj liab" ntawm ob sab tom qab etching, uas ua rau cov kab sib nrug, ua rau covluam ntawv boardua tsis tau raws li cov neeg siv khoom xav tau thiab tej zaum yuav raug tsis lees paub.Tus nqi tsim khoom ntawm PCB tau nce ntau heev vim qhov tsis lees paub.
Hauv PCB pov thawj, ib zaug muaj teeb meem nrog cov txheej txheem etching, nws yuav tsum yog ib qho teeb meem batch, uas nws thiaj li yuav ua rau muaj kev phom sij loj rau qhov zoo ntawm cov khoom.Yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb los nrhiav qhov tsim nyogPCB pov thawj manufacturers.
