Muaj kev nkag siab yooj yim ntawm cov ntawv luam tawm Circuit Board terminology tuaj yeem ua haujlwm nrog lub tuam txhab tsim khoom PCB sai dua thiab yooj yim dua. Cov ntsiab lus ntawm lub rooj tsav xwm Circuit Court no yuav pab koj nkag siab qee cov lus tshaj plaws hauv kev lag luam. Txawm hais tias qhov no tsis yog ib daim ntawv teev npe tag nrho, nws yog ib qho chaw zoo rau koj siv.
Nyob rau tib nplooj ntawv nrog koj cov chaw tsim khoom cog lus (CM) yog qhov tseem ceeb rau qhov tseeb embodiment ntawm koj lub hom phiaj tsim los tsim yam tsis muaj kev txom nyem los ntawm qhov tsis tsim nyog.quote ncua, redesigns thiab/los yog board respins. Kev txiav txim siab hauv kev sib txuas lus ntawm txhua tus neeg koom nrog hauv koj pawg thawj coj kev txhim kho yog qhov tseem ceeb.
Daim ntawv teev cov ntsiab lus tseem ceeb PCB Design Terminology
Printed Circuit Board Terminology
Qee cov ntsiab lus tseem ceeb luam tawm hauv Circuit Board tsom rau kev piav qhia lub cev qauv ntawm PCB. Cov ntsiab lus no kuj tau hais txog kev tsim thiab kev tsim khoom, yog li nws tseem ceeb heev uas yuav tsum tau kawm ua ntej.
Txheej:Txhua lub rooj tsav xwm hauv Circuit Court yog tsim nyob rau hauv cov khaubncaws sab nraud povtseg, thiab cov khaubncaws sab nraud povtseg raug nias ua ke los ua ib qhostackup. Txhua txheej suav nrog etched tooj liab, uas tsim cov conductors ntawm txhua txheej.
Copper ncuav:Cov cheeb tsam ntawm PCB uas tau sau nrog thaj tsam loj ntawm tooj liab. Cov cheeb tsam no tej zaum yuav txawv txawv.
Cov kab thiab kab sib kis:Cov ntsiab lus no yog siv sib hloov, tshwj xeeb tshaj yog rau kev kub ceev PCBs.
Teeb liab vs. dav hlau txheej:Lub teeb liab txheej yog tsim los tsuas yog nqa cov teeb liab hluav taws xob, tab sis nws kuj tseem tuaj yeem muaj tooj liab polygons uas muab hauv av lossis lub zog. Cov txheej txheem dav hlau yog npaj los ua kom tiav cov dav hlau yam tsis muaj teeb meem.
Vias:Cov no yog cov tho qhov me me hauv PCB uas tso cai rau ib txoj kab txav ntawm ob txheej.
Cov khoom xyaw:Hais txog txhua qhov chaw uas tau muab tso rau hauv PCB, suav nrog cov khoom siv yooj yim xws li resistors, connectors, integrated circuits, thiab ntau ntxiv. Cov Cheebtsam tuaj yeem txuas tau los ntawm kev raug soldered rau saum npoo (SMD Cheebtsam) los yog nrog cov hlau lead uas tau soldered rau hauv tooj liab qhov (los ntawm-qhov khoom) ntawm lub rooj tsavxwm.
Pads thiab qhov:Ob leeg ntawm no yog siv los mount cov khoom rau lub rooj tsavxwm Circuit Court thiab yog siv los ua ib qho chaw los thov solder.
Silkscreen:Qhov no yog cov ntawv nyeem thiab lub logo luam tawm ntawm qhov chaw ntawm PCB. Qhov no muaj cov ntaub ntawv hais txog cov txheej txheem, lub tuam txhab logos lossis cov lej, cov neeg tsim khoom siv, lossis lwm yam ntaub ntawv xav tau rau kev tsim, sib dhos, thiab kev siv tsis tu ncua.
Reference designators:Cov no qhia cov neeg tsim qauv thiab cov khoom sib dhos uas cov khoom siv tau muab tso rau hauv qhov chaw sib txawv ntawm lub rooj tsav xwm Circuit Court. Txhua yam khoom muaj tus tsim qauv siv, thiab cov neeg tsim qauv no tuaj yeem pom hauv cov ntaub ntawv tsim hauv koj li ECAD software.
Soldermask:Qhov no yog txheej saum toj kawg nkaus hauv PCB uas muab lub rooj tsav xwm hauv Circuit Court nws cov xim xim (feem ntau yog ntsuab).
