Multilayer PCB Circuit Board yuav tsum tau them sai sai rau qhov teeb meem ze-qhov
Multilayer PCB circuit board tuam txhab uas muag feem ntau ntsib "qhov rau kab ze dhau, dhau ntawm lub peev xwm ntawm cov txheej txheem", peb tsim lub PCB pawg thawj coj saib, qhov kev txiav txim siab tshaj plaws yog yuav ua li cas cov xaim tuaj yeem txuas rau txhua txheej nrog cov kab teeb liab tsim nyog tshaj plaws. . Qhov ntau ntom lub siab-ceev pcb kab dhau lub qhov (ntawm) ntau dua qhov ceev, dhau lub qhov tuaj yeem ua lub luag haujlwm ntawm cov hluav taws xob sib txuas ntawm txheej.
Yog li, qhov teeb meem zoo li cas yuav tshwm sim los ntawm qhov sib thooj ntawm qhov chaw tsim khoom? Thiab peb yuav tsum xyuam xim rau qhov teeb meem nyob ze li cas? Cov hauv qab no yog cov lus piav qhia luv luv.
1. kev ua haujlwm drilling yog tias ob lub qhov nyob ze dhau ua ke yuav cuam tshuam rau PCB drilling txheej txheem sijhawm. Raws li qhov tshwm sim ntawm qhov drilling thawj qhov tom qab lub qhov thib ob nyob rau hauv cov kev taw qhia ntawm drilling cov khoom nyob rau hauv ib sab yuav nyias nyias, ua rau lub zog tsis sib xws thiab laum nozzle kub dissipation, ua rau tawg laum nozzle, uas ua rau PCB qhov tawg yog tsis. zoo nkauj los yog xau drilling tsis yog conductive.
2. PC multilayer board hla lub qhov yuav nyob rau hauv txhua txheej ntawm txoj kab muaj lub nplhaib lub nplhaib, thiab txhua txheej ntawm lub nplhaib lub nplhaib nyob ib ncig ntawm ib puag ncig sib txawv, muaj ib txoj kab clip tsis yog ib txoj kab clip. pcb board Hoobkas cam engineer superior nyob rau hauv lub sij hawm ntawm cov ntaub ntawv, yuav nyob ze rau ntawm clip kab los yog lub qhov thiab lub qhov ze ze rau lub qhov nplhaib txiav tawm ib feem ntawm cov ntaub ntawv, kom ntseeg tau tias lub vuam nplhaib sib txawv network tooj liab / kab muaj kev nyab xeeb ntawm 3mil.
3. Lub qhov kam rau ua qhov drilling yog tsawg dua los yog sib npaug rau 0.05mm, thaum qhov kev kam rau siab nce mus txog qhov txwv ntau cov boards yuav muaj cov xwm txheej hauv qab no.
(1) Thaum cov kab ntom ntom ntawm lub qhov rau lwm cov ntsiab lus 360 degree tsis xwm yeem tshwm sim me me, kom muaj kev nyab xeeb ntawm 3mil, lub ncoo tuaj yeem tshwm sim ntau txoj kev txiav.
(2) raws li cov ntaub ntawv cov ntaub ntawv suav, qhov ntug rau kab ntug 6mil, qhov nplhaib 4mil, lub nplhaib rau kab nkaus xwb 2mil, kom ntseeg tau tias muaj 3mil kev nyab xeeb qhov sib nrug ntawm lub nplhaib mus rau kab yuav tsum tau txiav 1mil solder nplhaib , tom qab txiav lub ncoo tsuas yog 3mil. thaum lub qhov kam rau ua offset yog lub siab txwv ntawm 0.05mm (2mil), lub nplhaib lub nplhaib tsuas yog 1mil.
4. PCB ntau lawm yuav tshwm sim nyob rau hauv tib qho kev taw qhia ntawm ib qho me me ntawm offset, cov kev taw qhia ntawm lub ncoo raug txiav irregularly, qhov phem tshaj tshwm sim kuj yuav ua rau ib tug neeg qhov tawg solder nplhaib.
5. PCB multilayer board nyob rau hauv qhov cuam tshuam ntawm cov xovxwm haum sib txawv. Rau-txheej board, piv txwv li, ob lub core board ntxiv rau cov ntawv ci tooj liab nias ua ke los tsim ib lub rooj tsav xwm rau-txheej. Nias txheej txheem, core board 1, core board 2 pressed ua ke tej zaum yuav muaj tsawg tshaj li los yog sib npaug rau 0.05mm sib txawv, nias ua ke tom qab lub puab txheej ntawm lub qhov yuav tshwm 360 degree tsis sib txawv.
Cov teeb meem saum toj no txiav txim siab tias PCB tawm los thiab PCB kev ua tau zoo yog cuam tshuam los ntawm cov txheej txheem drilling. Yog tias lub nplhaib lub qhov me me dhau lawm thiab tsis muaj qhov ua tiav tooj liab tiv thaiv ib puag ncig ntawm lub qhov, txawm hais tias PCB tuaj yeem dhau qhov kev sim qhib luv luv thiab kev siv cov khoom yuav tsis muaj teeb meem, tab sis kev siv lub sij hawm ntev ntawm kev ntseeg siab yog tseem. tsis txaus.
Yog li ntawd, CITIC Tuam Tshoj muab ntau txheej PCB board, high-ceev PCB board qhov rau lub qhov, qhov rau kab qhov kev pom zoo.
(1) Multilayer board puab txheej qhov rau kab rau tooj liab.
4 txheej: tsis tas yuav tswj
6 txheej: Ntau dua lossis sib npaug li 6mil
8 txheej: Ntau dua lossis sib npaug li 7mil
10 txheej lossis ntau dua: Ntau dua lossis sib npaug li 8mil
(2) Tshaj-qhov puab txoj kab uas hla ntug sib nrug.
Nrog lub network perforation: Ntau dua lossis sib npaug ntawm 8mil (0.2mm)
Sib txawv network perforations: Ntau dua los yog sib npaug rau 12mil (0.3mm)
