PCB Board qauv

Tus qauv ntawm PCB Board suav nrog ntau cov board txheej txheej txheem qauv xws li ib leeg-txheej pob tw, thiab multi-al ... cov hauv qab no yog cov ncauj lus qhia ntxaws ntxaws:

1. ib-txheej pawg
Cov qauv sib xyaw: Muaj yog tooj liab ntawv ci rau tsuas yog ib sab, thiab tsis muaj tooj liab ntawv yog feem ntau yog siv rau xaim thiab soldering.
Daim Ntawv Thov Zaj Dab Tsi: Tsim nyog rau cov khoom siv hluav taws xob yooj yim, xws li cov khoom siv hluav taws xob, khoom ua si yog qhov tsawg thiab tus nqi qis, tab sis ib leeg yog ib leeg.

2.} cov txheej txheem ob chav
Substrate Cov Khoom Siv: cov feem ntau siv ib qho yog fr -4 nws muaj kev sib xyaw zoo, thiab tuaj yeem muab kev txhawb nqa hluav taws xob rau cov Circuit Court board.
Cov Txheej Txheem Ua Lag Luam: Uas yog, Tooj Ntawv Ntawv Nyiaj, uas tau muab faib rau ntawm cov qauv ntawm cov khoom siv me me Ntawv ci yog tsim nyog rau kev sib tw tsis zoo .
Cov Khoom Siv Insulating: PP (Prepreg) yog siv los ua cov txheej txheem insulating nyob hauv ob-nplooj fiber ntau, uas yuav tsis muaj luv ntawm ob txheej .
Cov khoom tiv thaiv saum npoo: Xws li cov ntsej muag tawv nqaij thiab xeb, thiab tiv thaiv cov pa liab, thiab tiv thaiv kom tsis txhob muaj qhov chaw nkaum, nrog tsuas yog cov ntaub qhwv liab; Cov kab lus silkscreen feem ntau yog cov number case dawb, siv los luam cov ntawv lossis cov cim xws li cov chaw sib koom ua ke thiab kho cov kev sib dhos thiab kev txij nkawm.
Daim Ntawv Thov Zaj Dab Tsi: Cov txheej txheem ntau lawm yog qhov yooj yim dua li cov khoom siv multi-} nws yog qhov ntau tshaj li ntawm ib qho-txheej pob tw .

3. multi-al-txheej txiag
Txheej Txheem Txheej Txheem: Siv rau kev tso cov khoom sib txuas thiab xaim, txheej txheem sib txuas (hauv qab txheej txheem ntawm cov txheej txheem sib txawv
Cov txheej txheem hluav taws xob thiab av txheej: feem ntau nyob hauv nruab nrab txheej, xws li txheej txheem tooj liab, thiab nruab nrab ntawm cov txheej txheem-txheej txheem 2} wiring txheej rau lwm pawg ntawm cov cim kab mob .
Cov txheej txheej ntawm: Fr -4 lossis lwm cov ntaub ntawv insulating, tiv thaiv kev ywj pheej thiab muaj kev ruaj ntseg ntawm cov cim.
Vias: suav nrog cov qhov muag tsis pom, thiab faus qhov {{}} Cov qhov muag dig muag tau siv los txuas cov txheej saum toj kawg nkaus thiab cov txheej txheem sab hauv, feem ntau tuaj yeem txo txoj kev ntev thiab ua rau muaj kev nkag rau txoj kev kis tau nrawm dua; faus qhov yog lub luag haujlwm rau cov khoom sib txuas hluav taws xob nruab nrab ntawm cov kab ntawv uas tsis pom kev, muaj ntau txoj kev sib txuas thaum lub rooj zaum high .
Cov txheej txheem saum npoo av: zoo ib yam li ob-txheej ci daim npog thiab lwm yam kev kho mob loj dua, kev ua si kom txhim kho kev coj ua thiab kev ua kom zoo nkauj {}}
Daim Ntawv Thov Zaj Dab Tsi: Tsim nyog rau high-ceev, kev kub ceev, thiab lwm yam ntawm cov txheej txheem hluav taws xob, thiab lwm zaus cov kev xav tau ntawm Circuit Court {}}
