Yuav Ua Li Cas Tsim Cov PCBs Zoo? Cov Lus Qhia Txog Cov Kauj Ruam Tseem Ceeb Ntawm Kev Tsim PCB
Cov Txheej Txheem Tsim Khoom PCB
Kauj Ruam 1: Kev Txheeb Xyuas Cov Ntaub Ntawv
Ua ntej tsim khoom, tus neeg tsim khoom PCB yuav xyuas cov ntaub ntawv tsim cov ntawv uas tus neeg siv khoom muab, suav nrog qhov loj ntawm cov ntawv, cov txheej txheem yuav tsum tau ua, thiab ntau npaum li cas ntawm cov khoom. Kev tsim khoom tsuas yog ua tom qab tau pom zoo nrog tus neeg siv khoom.
Kauj Ruam 2: Kev Txiav Khoom Siv
Raws li cov ntaub ntawv ua daim ntawv ntawm cov neeg siv khoom, txiav cov ntawv ua khoom ua tej daim me me uas ua tau raws li qhov yuav tsum tau ua. Kev ua haujlwm tshwj xeeb: cov khoom siv phaj loj → txiav raws li qhov yuav tsum tau ua ntawm MI → txiav daim ntawv → txiav ces kaum/sib tsoo ntug → tso daim ntawv tawm.
Kauj Ruam 3: Kev Khawb Av
Tho qhov uas xav tau ntawm qhov chaw sib xws ntawm PCB board. Kev ua haujlwm tshwj xeeb: cov khoom siv phaj loj → txiav raws li MI xav tau → kho → txiav ces kaum / sib tsoo ntug → tso tawm phaj.
Kauj Ruam 4: Tooj Liab Sib Tsoo
Ib txheej tooj liab nyias nyias raug tso rau ntawm qhov insulating. Kev ua haujlwm tshwj xeeb: kev sib tsoo ntxhib → dai lub rooj tsavxwm → kab tooj liab tsis siv neeg → txo lub rooj tsavxwm → tsau rau hauv 1% dilute H2SO4 → ua kom tooj liab tuab.
Kauj Ruam 5: Hloov Duab
Hloov cov duab los ntawm zaj duab xis tsim tawm mus rau lub rooj tsavxwm. Cov haujlwm tshwj xeeb: hemp board → zaj duab xis nias → sawv ntsug → sib dhos → raug → sawv ntsug → kev txhim kho → kev tshuaj xyuas.
Kauj Ruam 6: Kev Sib Txuas Duab
Siv hluav taws xob los pleev xim rau ib txheej tooj liab uas muaj qhov tuab thiab ib txheej kub nickel lossis tin rau ntawm daim ntawv tooj liab uas raug nthuav tawm lossis phab ntsa qhov ntawm tus qauv hluav taws xob. Kev ua haujlwm tshwj xeeb: phaj sab saud → tshem roj → ntxuav dej theem ob → xeb me me → ntxuav dej → ntxuav kua qaub → plating tooj liab → ntxuav dej → so kua qaub → plating tin → ntxuav dej → phaj sab hauv qab.
Kauj Ruam 7: Tshem Tawm Zaj Duab Xis
Tshem tawm cov txheej txheej tiv thaiv electroplating nrog NaOH kua kom pom cov txheej tooj liab uas tsis yog-circuit.
Kauj Ruam 8: Kev Txiav
Tshem tawm cov khoom uas tsis yog voj voog nrog cov tshuaj reagent.
Kauj Ruam 9: Lub Npog Ncauj Solder
Hloov cov duab ntawm zaj duab xis ntsuab mus rau ntawm lub rooj tsavxwm, feem ntau yog los tiv thaiv lub voj voog thiab tiv thaiv kev sib txuas ntawm cov khoom nrog tin ntawm lub voj voog.
Kauj Ruam 10: Silkscreen
Luam cov cim uas paub tau ntawm PCB board. Cov haujlwm tshwj xeeb: tom qab kho qhov kawg ntawm lub npog ntsej muag solder, txias thiab sawv ntsug, kho qhov screen, luam cov cim, thiab thaum kawg kho.
Kauj Ruam 11: Cov Ntiv Tes Kub
Siv ib txheej nickel/kub uas tuab raws li qhov xav tau rau ntawm tus ntiv tes ntsaws kom txhim kho nws qhov tawv thiab tiv taus kev hnav.
Kauj Ruam 12: Tsim
Siv lub pwm lossis lub tshuab CNC los xuas cov duab uas tus neeg siv khoom xav tau.
Kauj Ruam 13: Kev Ntsuas
Cov teeb meem ua haujlwm uas tshwm sim los ntawm cov voj voog qhib, cov voj voog luv luv, thiab lwm yam, nyuaj rau pom los ntawm kev tshuaj xyuas pom thiab tuaj yeem kuaj xyuas siv lub tshuab sim ya.
