Koj twb paub tias txhua cov khoom siv hluav taws xob muaj cov khoom siv hluav taws xob. PCBs, lossis luam tawm cov laug cam hluav taws xob, yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no. Lub rooj tsavxwm ntsuab nrog cov kab sib luag thiab cov qauv yog hu ua PCB. Hauv cov khoom siv hluav taws xob, cov cim ntawm PCB xyuas kom txhua feem ua haujlwm ua ke zoo. Kev tsim khoom ntawm tus PCB muaj ntau lub cheebtsam thiab cov kauj ruam. Cov theem kawg ntawm kev ua cov ntawv luam tawm hluav taws xob (PCB) yog los ntxiv screen luam ntawv rau ntawm txheej sab saum toj.
Kev Ntsuam Xyuas Kev Luam Ntawv yog cov txheej txheem ntawm kev thov Ink txiav rau hauv Circuit Court, cov ntsiab lus cim, cov ntsiab lus logo, Qhov sib koom ua ke yog lub chaw tsim khoom lub vijtsam luam ntawv. Nws qee zaus tshwm sim hauv vuam raws, tab sis tus nqi ntawm kev tau txais muaj siab. PCB tshuaj ntsuam luam ntawv pab cov tuam txhab thiab cov neeg tsim qauv sai tiag txheeb xyuas cov txheej txheem sib xyaw. PCB screen luam ntawv yuav ua kom ntseeg tau tias ntu tuaj yeem rov ua haujlwm. Lub vijtsam luam ntawv yuav muab cov kws tshaj lij lossis cov kws tshaj lij nrog cov lus qhia nyob rau qhov twg thiab yuav tsum muab tso rau ntawm PCB.
Dab tsi yog PCB npo luam ntawv?
Xav tias koj ua haujlwm ntawm DIY txoj haujlwm los tsim cov futuristic smartwatch ntawm kos. Koj tus PCB yog zoo li tus thawj coj rau qhov kev siv hluav taws xob no, thiab tshuaj ntsuam kos duab yog koj txoj hauv kev los coj koj thiab ib tus neeg koom nrog cov txheej txheem los ua ke.
Vijtsam luam ntawv ntawm PCB yog txheej ntawm Ink luam tawm ntawm cov npoo ntawm cov Circuit Court Board. Nws feem ntau yog ua los ntawm cov ntaub ntawv polymer lossis cov ntaub ntawv sib xyaw thiab siv los ntawm kev tshuaj ntsuam luam ntawv. Tus number case yog thov los ntawm mesh npo, uas ua raws li tus qauv rau cov qauv xav tau. Lub vijtsam tau muab tso rau ntawm PCB, thiab number case tau yuam dhau ntawm qhov screen thiab mus rau hauv lub rooj tsavxwm. Tus qauv tshuaj ntsuam siv los ntawm cov tuam ntxhab yog xim dub, daj thiab dawb. Thaum siv PCB software, feem ntau siv cov fonts tuaj yeem siv rau hauv kev tsim qauv ntawm lub vijtsam luam ntawv txheej.
Nws feem ntau yog siv rau sab saum toj thiab hauv qab txheej ntawm cov Circuit Court Board. Siv tshuaj ntsuam luam ntawv, qhov chaw ntawm PCB Board tuaj yeem luam tawm nrog cov ntawv nyeem, cov ntawv cim thiab cov cim. Cheebtsam, lawv qhov chaw nyob, qee cov npe, cov lej lej, hom logo, thiab lwm cov ntaub ntawv raug nthuav tawm.
Txawm hais tias lub vijtsam luam ntawv txheej tsis muaj dab tsi ua nrog cov hluav taws xob ua haujlwm tiag tiag ntawm lub rooj tsavxwm, nws yog qhov tseem ceeb rau cov txheej txheem ntawm lub tsev, kev kuaj mob, thiab siv lub rooj tsavxwm. Pab nrhiav tej yam thiab muab tso rau hauv qhov chaw yog kom txhua yam yog txoj hauv kev thiab txoj hauv kev. Nws muaj txiaj ntsig zoo heev rau cov txheej txheem los ua ke vim tias nws yooj yim to taub rau cov kws tshaj lij thiab cov sib sau ua ke. Tam sim no koj paub cov ntsiab lus ntawm tshuaj ntsuam luam ntawv ntawm cov luam ntawv Circuit Coad, cia saib nws cov kev siv dav dav.
Cov ntaub ntawv ntawm PCB npo luam ntawv yog dab tsi?
Raws li tau hais ua ntej lawm, tshuaj ntsuam luam ntawv ntawm PCB yuav tsis muaj kev cuam tshuam dab tsi ntawm cov haujlwm ntawm PCB; Txawm li cas los xij, nws tus nqi nyob hauv cov ntaub ntawv nws muab. Piv txwv li, nws yuav pab tau txhua tus:
Cov cim ceeb toom:Txheeb xyuas cov cim ceeb toom qhia txog cov hluav taws kub uas yuav tsum tau saib xyuas thiab saib xyuas thaum ua haujlwm.
Polarity:Nkag siab txog cov cheebtsam polarity kom raug muab nruab tiv thaiv kom zoo. Tus Pin cov neeg ntaus cim muab cov ntaub ntawv qhia kom ntseeg tau tias kev sib dhos tau.
Xeem taw tes:Txoj hauj lwm kev ntsuas point Cov ntsuas pom ntawm qhov screen los pab cov kws tsim qauv tsim qauv hauv PCB xeem thiab commissioning.
Qhov Ntsuas Hluav Taws Xob: Cheebtsam tau txheeb xyuas los ntawm cov cim qhia, tus cim tshwj xeeb rau txhua qhov chaw sib dhos ntawm PCB.
Tooj: Nrhiav tus lej tshwj xeeb ntawm PCB npo luam ntawv, qhia txog cov chaw tsim tshuaj paus, tus lej version, thiab lwm yam.
Cov cim tivthaiv tivthaiv: Rau cov khoom sib xyaw tshwj xeeb xws li diodes thiab optocousplers, cov cim tivthaiv, cov cim tivthaiv cov luam tawm ntawm cov luam ntawv raug raws li kev teeb tsa.
Hloov Chaw:Lub neej ntawd hloov chaw tau piav qhia nyob rau PCB npo, txhim kho lub zog siv ntawm lub rooj tsavxwm.
Cov Cheebtsam Dense:Tus PIN rau ntawm kev tshuaj ntsuam luam ntawv cov neeg luam ntawv kuaj thiab debugging ntawm cov pob khoom sib xyaw xws li pob zeb pob zeb (BGA).
Kev daws teeb meem thiab kho:Silkscreen cim tau yooj yim txheeb xyuas thiab nrhiav cov txheej txheem ntawm tus kheej, ceev cov txheej txheem kho.
Cov ntaub ntawv tsim khoom:Txhob lo lo ntxhuav kev khij muaj kev tsim cov khoom lag luam tsim nyog thiab sib dhos ua ke cov ntaub ntawv. Qhov no suav nrog cov ntawv ceeb toom cai tswj hwm, tuam txhab logo, cov hnub tsim khoom, thiab lwm cov hnub tswj tseem ceeb thiab muaj cov ntsiab lus tseem ceeb.
Hom: Cov cim no pab txhawb rau PCB txoj kev zoo nkauj thiab hom. Ua ke cov ntsiab lus, cov cim, thiab cov xim xaiv tau kev pom kev pom thiab kev paub txog kev ua haujlwm.
Dab tsi yog qhov zoo tshaj plaws thickness ntawm tshuaj ntsuam luam ntawv ntawm PCB?
Lub thickness ntawm lub vijtsam ntawm PCB cuam tshuam los ntawm qhov loj me ntawm lub vijtsam thiab tus nqi ntawm number case siv. Feem ntau, tshuaj ntsuam luam ntawv hauv PCBs tau ua tiav raws li cov txheej nplua, feem ntau nrog cov tuab ntawm tsawg dua 0.1 hli. Qhov no tso cai rau tus number case yuav tsum tau ua ntawv thov yam tsis tau hloov pauv tau hloov pauv tag nrho tuab ntawm PCB.
Lub qhov tob ntawm lub tshuab raj ntawm tus PCB tuaj yeem sib txawv raws ntau yam ntawm kev tsim khoom, suav nrog cov qauv kev tsim nyog, thiab tsim qauv hauv kev lag luam. Feem ntau, qhov tob ntawm tshuaj ntsuam kev luam ntawv ntawm PCB yog qhov nyias me dua piv rau lwm txheej hauv PCB.
Muaj qee kis, cov tuab ntawm lub vijtsam luam tawm pcb txheej feem ntau yog li 0.02 hli rau 0.1 hli rau 0.1 mm (20 txog 100 microns). Qhov no yog qhov tseem ceeb heev los xav txog cov kev ntsuas no yog cov kwv yees kwv yees thiab tej zaum yuav sib txawv raws ntau yam.
Txawm hais tias qhov screen nyob rau hauv cov ntawv luam tawm hluav taws xob board yog qhov tsis yooj yim, nws tseem muab ntau qhov pom kev thiab elasticity rau lub cim. Cov tuab tuab yog ua tib zoo saib xyuas kom ntseeg tau tias nws tsis cuam tshuam txoj haujlwm ntawm tus PCB, ua haujlwm tsis zoo, lossis ua rau muaj teeb meem thaum lub sijhawm tsim khoom.
