Raws li cov ntsiab lus tseem ceeb ntawm cov khoom siv suab, kev tsim thiab kev ua haujlwm ntawm lubaudio circuit boardua lub luag haujlwm txiav txim siab hauv lub suab zoo, kev ua haujlwm zoo, thiab kev ruaj ntseg ntawm lub suab tag nrho. Ntau hom suab Circuit boards muaj qhov sib txawv tseem ceeb hauv ntau yam, uas cuam tshuam ncaj qha rau qhov zoo thiab kev ua lag luam ntawm cov khoom siv suab. Hauv qab no, peb yuav delve rau hauv qhov sib txawv ntawm audio circuit boards los ntawm ntau qhov ntev.
Qhov sib txawv ntawm Cov Txheej Txheem thiab Cov Qauv
Ib txheej Circuit Court board
Cov qauv yog qhov yooj yim tshaj plaws, muaj tsuas yog ib txheej conductive, uas tag nrho cov kev sib txuas hauv Circuit Court tau ua tiav. Hom kab hluav taws xob no muaj tus nqi qis thiab cov txheej txheem tsim khoom yooj yim, thiab muaj ntau dua nyob rau hauv cov khoom siv suab yooj yim thaum ntxov thiab qis -kawg suab khoom uas muaj kev cuam tshuam rau tus nqi. Txawm li cas los xij, vim qhov txwv tsis pub muaj qhov chaw ntawm ib txheej, qhov nyuaj ntawm nws cov xov hlau thiab cov khoom siv uas nws tuaj yeem ua tau raug txwv, ua rau nws tsis tsim nyog rau lub suab tsim nrog cov haujlwm nyuaj thiab cov kev xav tau siab rau kev teeb tsa hauv Circuit Court.
Ob txheej txheej Circuit Board
Nruab nrog ob txheej txheej conductive, hluav taws xob kev sib txuas ntawm ob txheej yog ua tiav los ntawm metalized vias. Muab piv rau ib qho - txheej Circuit Court boards, ob npaug - txheej Circuit Court boards tau txhim kho qhov chaw txuas, ua kom muaj ntau yam kev tsim hluav taws xob hauv Circuit Court thiab ua kom haum rau ntau yam khoom. Qhov no tso cai rau cov khoom siv suab sib txuas ua haujlwm ntau dua, xws li ntxiv qee qhov kev hloov kho suab yooj yim. Hauv qee cov khoom nruab nrab mus rau qis kawg xws li cov neeg hais lus hauv tsev thiab cov neeg hais lus hauv computer, ob chav - txheej txheej Circuit Court boards tau siv dav, nrhiav qhov sib npaug zoo ntawm tus nqi thiab kev ua haujlwm.
Multilayer Circuit Board
Feem ntau, nws muaj plaub los yog ntau tshaj cov txheej txheem, uas txuas rau ib leeg los ntawm vias lossis qhov muag tsis pom qhov faus. Multilayer circuit boards zoo heev txhim kho qhov sib dhos ntom ntom thiab xaim yooj yooj yim ntawm Circuit Boards. Hauv high-kawg suab khoom, ntau- txheej txheej Circuit Court boards nyiam vim qhov xav tau los tswj cov teeb liab ua haujlwm nyuaj, ntau-channel tso tawm, thiab muaj zog tswj kev ua haujlwm. Piv txwv li, cov kws tshaj lij sau ntawv studio saib xyuas cov neeg hais lus yuav muaj cov rooj sib tham tsim nrog 6, 8, lossis ntau txheej txheej, txhua txheej lub luag haujlwm rau cov haujlwm sib txawv xws li teeb liab txheej, txheej txheej hluav taws xob, txheej hauv av, thiab lwm yam, txo cov teeb liab cuam tshuam, txhim kho kev ruaj ntseg thiab qhov tseeb ntawm lub teeb liab kis tau tus mob, thiab ua kom muaj siab - suab tawm suab zoo.
Qhov sib txawv ntawm cov khoom siv substrate
Ordinary fiberglass board
Qhov no yog qhov feem ntau siv substrate nyob rau hauv lub suab Circuit Court boards. FR-4 yog tsim los ntawm immersing iav fiber ntau daim ntaub nyob rau hauv epoxy resin thiab kub nias nws, uas muaj zoo hluav taws xob rwb thaiv tsev kev ua tau zoo, mechanical zog, thiab seem stability. Nws tuaj yeem hloov mus rau qhov kub thiab txias ua haujlwm ntawm cov khoom siv suab nrov feem ntau, thiab nws cov nqi kuj tseem pheej yig. Nws yog dav siv nyob rau hauv ntau yam suab khoom los ntawm nkag-theem mus rau nruab nrab mus rau siab kawg. Ob qho tib si hauv tsev neeg Bluetooth hais lus thiab qee lub voj voog ntawm cov kws tshaj lij theem tuaj yeem siv FR-4 cov khoom siv hluav taws xob.
Hlau raws li Circuit Board
Siv cov ntaub ntawv hlau xws li txhuas, tooj liab, thiab lwm yam raws li substrates, hlau substrates muaj kev ua haujlwm zoo heev thaum tshav kub kub dissipation. Thaum lub sijhawm ua haujlwm ntawm cov khoom siv suab, tshwj xeeb tshaj yog lub zog amplification thiab lwm qhov chaw, cov cua kub ntau yog generated. Yog tias cov cua kub dissipation tsis raws sijhawm, nws yuav cuam tshuam rau kev ua haujlwm thiab kev ua neej nyob ntawm cov khoom siv hluav taws xob, yog li cuam tshuam rau lub suab zoo. Hlau raws li Circuit Court boards sai sai dissipate tshav kub, xyuas kom meej tias cov Cheebtsam ntawm lub rooj tsavxwm ua hauj lwm ntawm qhov tsim nyog kub. Yog li ntawd, nyob rau hauv siab - fais fab kev amplifiers, lub tsheb lub tshuab, thiab lwm yam khoom siv suab uas yuav tsum tau high tshav kub dissipation, hlau raws li Circuit Court boards yog dav siv, uas yuav pab txhim kho lub stability thiab kev cia siab ntawm cov cuab yeej thiab xyuas kom meej lub suab zoo nyob rau hauv ntev - lub sij hawm ua hauj lwm siab load.
High zaus board
Thaum lub suab kaw lus suav nrog kev ua haujlwm siab- zaus teeb liab, xws li qee qhov siab -kawg wireless audio khoom uas yuav tsum tau ua haujlwm siab -frequency wireless signals xws li Bluetooth thiab Wi-nkaus, nrog rau kev ua kom raug siab - zaus suab signals, siab -frequency boards yog xav tau. High zaus boards muaj cov yam ntxwv ntawm qhov tsis tshua muaj dielectric tsis tu ncua thiab tsis tshua muaj dielectric poob, uas tuaj yeem txo cov teeb liab attenuation thiab distortion thaum kis tau tus mob, kom ntseeg tau tias muaj kev ncaj ncees thiab raug siab ntawm - zaus cov cim. Feem ntau cov siab- zaus boards suav nrog polytetrafluoroethylene thiab nws cov khoom sib xyaw. Txawm hais tias tus nqi siab, lawv yog qhov tseem ceeb hauv cov khoom siv suab siab- kawg uas ua raws cov suab zoo kawg nkaus thiab kev ua haujlwm tsis zoo.
