Ntau cov khaubncaws sab nraud povtseg, ntau txoj & nyuaj cov kev tsim yuav, thiab kim kim yuav raug nqi.
Muaj ntau tus txheej txheem PCB xa mus rau ntawm pawg thawj coj saib xyuas luam tawm muaj ntau tshaj ob hom tooj liab, xws li 4L, 6L, 8L, 10L, 12L, thiab lwm yam zoo li kev siv technology zoo tuaj, tib neeg tuaj yeem muab ntau npab tooj ntawm lub qub txeeg qub teg. Tam sim no, peb tuaj yeem ua tau 20L-32L FR4 PCB.
Los ntawm cov qauv no, engineer yuav ua rau ib txoj kab rau ntau cov khaubncaws sab nraud pov tseg rau lwm lub hom phiaj, xws li cov khaubncaws sab nraud povtseg rau lub hwjchim, rau cov teebmeem hloov, EMI shielding, rau kev sibcav, thiab lwm yam. Yuav kom tsis txhob muaj ntau cov khaubncaws sab nraud povtseg, Tshaj Plig ntawm lossis dig muag ntawm kev yuav tsim nyob rau hauv ntau txheej PCB. Rau lub rooj tsav tsheb ntau tshaj li 8 txheej, cov ntaub ntawv siab Tg FR4 yuav nrov tshaj qhov qub Tg FR4.
Yuav ua li cas yog cov PCBs uas muaj multilayer?
Lwm cov txheej txheem ntawm prepeg thiab cov ntaub ntawv tseem ceeb yog laminated ua ke hauv high temperature thiab siab los tsim Multilayer PCBs. Cov txheej txheem no ua kom paub tseeb tias huab cua tsis raug ntawm cov khaubncaws sab nraud povtseg, cov neeg sib tw ua txhua yam khoob los ntawm cov ntaub qhwv, thiab cov nplaum uas tuav cov txheej pov tseg ua ke zoo dua qub thiab kho. Qhov ntau ntawm cov ntaub ntawv ua ke yog nws kim heev los ntawm epoxy iav los ua kab txawv los yog Teflon cov ntaub ntawv.
Daim duab saum toj no qhia txog stackup ntawm 4-Layer / multilayer PCB. Prepeg thiab core yog cov tseem zoo tib yam khoom, tab sis prepeg yog tsis zoo kho, ua nws ntau malleable dua cov tub ntxhais.Lub alternating txheej yog ces muab tso rau hauv lub lamination xovxwm. Tsis tshua muaj siab kub thiab pressures yog siv rau lub stackup, ua rau lub prepeg rau "yaj" thiab koom nrog cov khaubncaws sab nraud povtseg. Tom qab txias tawm, qhov kawg tshwm sim yog ib qho nyuaj heev thiab khoom sib txuam muaj ntau yam khoom.
2. Qhia cov ntaub ntawv
UNIWELL circuits yog ib tug PCB & PCBA txiag nrog 10 xyoo kev ua haujlwm.Peb ua haujlwm nrog ntau tshaj 600 tus neeg nyob hauv khoos phis tawj, kev sib txuas lus, muaj kev kuaj thiab tswj, cov khoom kho mob, lub hwj huam mov, LED, CCTV, kev tshawb fawb thiab lwm yam khoom nyob rau hauv lub ntiaj teb-thoob khw. Thiab peb tau zoo siab lub koob npe nrov ntawm lawv.
