Qhov tsim nyog layout ntawm cov khoom siv hluav taws xob ntawm PCB pawg thawj coj saib yog qhov txuas tseem ceeb heev los txo cov vuam tsis xws luag! Cov Cheebtsam yuav tsum zam cov cheeb tsam uas muaj qhov muaj txiaj ntsig loj heev thiab qhov chaw muaj kev ntxhov siab sab hauv kom deb li deb tau, thiab cov txheej txheem yuav tsum ua kom zoo li qhov ua tau.
Txhawm rau kom siv ntau tshaj qhov chaw ntawm lub rooj tsav xwm hauv Circuit Court, kuv ntseeg tias ntau tus neeg koom tes tsim yuav sim muab cov khoom sib xyaw rau ntawm ntug ntawm lub rooj tsavxwm, tab sis qhov tseeb, qhov kev coj ua no yuav ua rau muaj teeb meem loj rau kev tsim khoom thiab PCBA los ua ke, thiab txawm tias txhuas. rau qhov tsis muaj peev xwm rau vuam sib dhos oh!
Niaj hnub no, cia peb tham txog qhov layout ntawm ntug ntaus ntawv hauv kev nthuav dav
Vaj huam sib luag sab ntaus ntawv layout txaus ntshai
01. Moulding board ntug milling board
Thaum cov khoom raug muab tso rau ze rau ntawm ntug ntawm lub phaj, lub vuam ncoo ntawm cov khoom yuav raug milled tawm thaum lub phaj milling tsim. Feem ntau, qhov kev ncua deb ntawm lub vuam ncoo thiab ntug yuav tsum siab tshaj 0.2 hli, txwv tsis pub lub vuam ncoo ntawm lub ntug ntaus ntawv yuav raug milled tawm thiab lub nraub qaum sib dhos tsis tuaj yeem vuam cov khoom.
02. Sib sau phaj ntug V-CUT
Yog tias lub ntug ntawm lub phaj yog Mosaic V-CUT, cov khoom yuav tsum tau nyob deb ntawm ntug ntawm lub phaj, vim hais tias V-CUT riam los ntawm nruab nrab ntawm lub phaj feem ntau yog ntau tshaj 0.4 hli ntawm ntug ntawm lub phaj. V-CUT, txwv tsis pub V-CUT riam yuav ua rau lub vuam phaj, ua rau cov khoom tsis tuaj yeem welded.
03. Cov khoom siv cuam tshuam
Cov txheej txheem ntawm cov khoom nyob ze rau ntawm ntug ntawm lub phaj thaum tsim yuav cuam tshuam nrog kev ua haujlwm ntawm cov khoom siv sib dhos tsis siv neeg, xws li yoj-soldering lossis reflow vuam tshuab, thaum sib dhos cov khoom.
04. Cov cuab yeej sib tsoo rau hauv cov khoom
Qhov ze ntawm ib qho kev tivthaiv yog rau ntawm ntug ntawm lub rooj tsavxwm, qhov ntau dua nws lub peev xwm los cuam tshuam nrog cov khoom sib dhos. Piv txwv li, cov khoom xws li cov khoom siv hluav taws xob loj, uas siab dua, yuav tsum tau muab tso rau deb ntawm ntug ntawm lub rooj tsavxwm dua li lwm cov khoom siv.
05. Lub Cheebtsam ntawm lub sub-board puas lawm
Tom qab cov khoom sib dhos ua tiav, cov khoom tiav yuav tsum tau muab cais tawm ntawm lub phaj. Thaum lub sij hawm sib cais, cov khoom uas nyob ze rau ntawm ntug yuav raug puas tsuaj, uas tej zaum yuav cuam tshuam thiab tsis yooj yim rau kev ntes thiab debug.
Cov hauv qab no yog qhia cov ntaub ntawv ntau lawm txog lub ntug ntaus ntawv nrug tsis txaus, ua rau koj puas tsuaj ~
Teeb meem piav qhia
Nws pom tias LED teeb ntawm ib yam khoom yog nyob ze rau ntawm ntug ntawm lub rooj tsavxwm thaum SMT muab tso rau, uas yog ib qho yooj yim yuav tsum tau bumped nyob rau hauv ntau lawm.
Teeb meem cuam tshuam
Kev tsim khoom thiab kev thauj mus los, nrog rau cov teeb ci LED yuav tawg thaum cov txheej txheem DIP hla txoj kev, uas yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom.
Teeb meem txuas ntxiv
Nws yog ib qho tsim nyog los hloov lub rooj tsavxwm thiab txav cov LED hauv lub rooj tsavxwm. Nyob rau tib lub sijhawm, nws tseem yuav koom nrog kev hloov pauv ntawm cov qauv coj teeb pom kev zoo, ua rau muaj kev ncua loj hauv kev tsim kho lub voj voog.
Kev pheej hmoo nrhiav pom cov khoom siv ntug
Qhov tseem ceeb ntawm cov qauv tsim qauv yog qhov tseeb, lub teeb yuav cuam tshuam rau vuam, hnyav yuav ncaj qha ua rau cov cuab yeej puas tsuaj, yog li yuav ua li cas kom ntseeg tau 0 teeb meem tsim, thiab ua tiav cov khoom tiav?
Nrog rau kev ua haujlwm ntawm kev sib dhos thiab kev tshuaj xyuas, ZOO TSHAJ PLAWS tuaj yeem txheeb xyuas cov cai tswj xyuas raws li qhov tsis sib xws ntawm qhov kev ncua deb ntawm ntug ntawm cov khoom siv. Nws kuj tseem muaj cov khoom tshwj xeeb tshuaj xyuas rau qhov kev teeb tsa ntawm cov khoom ntawm ntug ntawm lub phaj, nrog rau ntau yam kev soj ntsuam cov ncauj lus kom ntxaws xws li cov cuab yeej siab rau ntawm ntug ntawm lub phaj, cov cuab yeej qis rau ntawm ntug phaj, thiab cov cuab yeej siv rau kev taw qhia rail. ntug ntawm lub tshuab, uas tuaj yeem ua tau raws li qhov tsim nyog rau kev ntsuas kev nyab xeeb ntawm lub cuab yeej los ntawm ntug ntawm lub phaj.
