Yuav ua li cas teeb tus PCB wiring kab dav, thiab yog dab tsi yog qhov chaw dav rau PCB kab hlau dav?
Hauv PCB tsim, cov hlau yog qhov tseem ceeb tshaj plaws thiab siv sijhawm ua haujlwm. Thaum nqa tawm PCB xaim, kev xaiv ntawm kab dav yog qhov tseem ceeb heev. Kev xaiv ntawm kab dav tsis yog cuam tshuam ncaj qha thiab kis tau qhov nrawm ntawm lub teeb liab, tab sis kuj cuam tshuam tus nqi thiab kev ntseeg tau ntawm tag nrho cov qauv.
1. Cov hauv paus ntsiab lus rau xaiv PCB kab hlau wiring
(1) Cov paib cim
Feem ntau hais lus, lub kab yuav tsum tau rauKev kub ceev thiab siab-zausCov cim yog me dua li cov cim tsawg zaus. Tus me dua cov kab, qhov ntau dua qhov ceev tam sim no, ua rau muaj cov impedance qis thiab zoo dua kis tau cov khoom lag luam zoo. Cov hom sib txawv uas yuav tsum muaj cov kab sib txawv. Piv txwv li, txoj kab dav thiab txuas ntawm cov kev ntsuas siab ceev digital yog me dua li cov cim analog. Nyob rau hauv dav dav, cov phiajcim nrog tsawg ntev, qis nrawm, thiab tsawg txoj kab nqes tuaj yeem siv lwm cov kab dav dav dav; Txog kev kub ceev thiab cov kab nqes qib siab thiab cov kab ke loj yuav tsum tau siv los txo cov teeb liab cov kab mob CrosStalk muaj peev xwm.
(2) Tus naj npawb ntawm Board txheej txheem
Thaum tus naj npawb ntawm pcb txheej nce, tshwj xeeb yuav tsum tau them rau qhov loj ntawm kab dav. Qhov loj interlayer spacing ua rau muaj kev sib txuas ntau dua, thiab nws yog ib qho tsim nyog los ua kom cov kab dav lossis txuas rau kev them nyiaj.
(3) Cov Txheej Txheem Tsim Kev Lag Luam
Kev tsim hluav taws xob ntawm PCB Board kab dav yuav tsum xav txog lub Hoobkas cov txheej txheem kev tsim, yog li ntawd peb yuav tsum tau tswj hwm, kev tswj hwm cov txheej txheem tshwj xeeb rau sab nraud / sab hauv, thiab lwm yam.
(4) raug nqi
Txoj kab dav yog ncaj qha rau tus nqi tsim khoom, thiab xaiv kab kab tsim nyog tuaj yeem txo tus nqi tsim khoom.
2. Kev siv cov nqi rau PCB kab hlau wire kev tsim qauv
Rau kev yooj yim ntawm kev siv, peb tau teev lub rooj tswj hwm lub rooj rau feem ntau yog siv kab pcb dav thiab kab sib txawv:
| Pcb txheej|Kab dav|Kab spacing |
| Ib txheej|10 mil|10 mil |
| Ob Txheej Txheej|7Mil|7Mil |
| 4 txheej|6Mil|6Mil |
| 6ths txheej|5ml|5ml |
| Lub Yim Txheej|4MIL|4MIL |
| Mult|Txheej|Tsawg dua 4mil|Tsawg dua 4mil |
3. Kev thov ntawm kev tsom xam cov kab ntawm kab dav
Hauv kev tsim khoom tiag tiag, cov qauv kev xaiv rau PCB kab hlau dav yuav tau hloov kho rau theem siab zoo kom ua tiav qhov kev tsim nyog ntawm tag nrho cov qauv. Feem ntau hais lus, kev xaiv pcb wiring kab yuav tsum tau mus rau hauv tus account cov khoom siv, teeb meem microwave, pcb txheej, thiab cov nuj nqis.
