Yuav ua li cas yog ib tug ob-sided multi-layer board?
PCB boards raug faib raws li tus naj npawb ntawm cov khaubncaws sab nraud povtseg: ib sab, ob sab thiab ntau txheej boards.Cov txheej txheem ntau txheej feem ntau yog 4-txheej boards lossis 6-txheej boards, thiab cov txheej txheem ntau txheej tuaj yeem ncav cuag ntau tshaj kaum txheej.Nws muaj peb hom kev faib loj hauv qab no:
Ib lub vaj huam sib luag: Ntawm qhov yooj yim tshaj plaws PCB, cov khoom siv yog tsom rau ntawm ib sab, thiab cov xov hlau yog concentrated rau sab nraud.Vim hais tias cov xov hlau tsuas yog tshwm sim ntawm ib sab, hom PCB no yog hu ua ib sab (Single-sided).Vim hais tias lub rooj tsavxwm ib leeg muaj ntau qhov kev txwv nruj rau kev tsim ntawm lub voj voog (vim tsuas muaj ib sab xwb, cov xov hlau tsis tuaj yeem hla thiab yuav tsum yog ib txoj hauv kev sib cais), yog li tsuas yog thaum ntxov circuits siv hom board.
Lub Rooj Tswjhwm Saib ob tog: Lub rooj tsav xwm zoo li no muaj cov xov hluav taws xob ntawm ob sab, tab sis yuav tsum siv ob sab xaim, yuav tsum muaj kev sib txuas ntawm ob sab.Cov "choj" ntawm cov circuits no hu ua vias.A via yog ib lub qhov me me ntim lossis coated nrog hlau ntawm PCB, uas tuaj yeem txuas nrog cov xov hlau ntawm ob sab.Vim tias thaj tsam ntawm lub rooj tsavxwm ob sab yog ob zaug loj dua li ntawm lub rooj tsavxwm ib leeg, thiab vim tias cov xaim tuaj yeem cuam tshuam (nws tuaj yeem raug mob rau sab nraud), nws yog qhov tsim nyog rau kev siv hauv circuits. uas yog qhov nyuaj tshaj li lub rooj tsav xwm ib leeg.
Multilayer board: Yuav kom nce thaj tsam uas tuaj yeem xaim tau, lub rooj tsav xwm multilayer siv ntau dua ib qho lossis ob sab txuas txuas.Siv ib qho ob sab ua cov txheej sab hauv, ob sab ib leeg raws li txheej txheej lossis ob sab ob sab raws li txheej sab hauv thiab ob sab ib sab raws li txheej txheej ntawm cov ntawv luam tawm Circuit Board.Qhov chaw thiab cov khoom siv insulating sib txuas ua ke ua ke thiab cov qauv luam tawm Circuit Court boards uas sib cuam tshuam raws li cov qauv tsim los ua plaub-txheej lossis rau-txheej luam ntawv Circuit Court boards, tseem hu ua multilayer printed circuit boards.Tus naj npawb ntawm cov khaubncaws sab nraud povtseg txhais tau hais tias muaj ob peb txheej txheej thaiv kev ywj pheej.Feem ntau tus naj npawb ntawm cov khaubncaws sab nraud povtseg yog sib npaug thiab muaj ob txheej txheej sab nraud.Feem ntau cov motherboards muaj 4 mus rau 8 txheej ntawm cov qauv, tab sis technically, PCB boards nrog ze li ntawm 100 txheej tuaj yeem ua tiav hauv txoj kev xav.Feem ntau cov khoos phis tawj loj loj siv ntau txheej motherboards, tab sis vim tias hom khoos phis tawj no tuaj yeem hloov tau los ntawm pawg ntawm ntau lub khoos phis tawj zoo tib yam, super-multilayer boards tau maj mam tsis siv.
Vim tias cov khaubncaws sab nraud povtseg hauv PCB yog nruj nruj, nws feem ntau tsis yooj yim pom tus lej tiag tiag, tab sis yog tias koj saib ze ntawm lub motherboard, koj tseem tuaj yeem pom nws.
Raws li qhov muag muag thiab tawv kev faib tawm: muab faib ua cov khoom siv hluav taws xob zoo tib yam thiab cov khoom siv hluav taws xob hloov tau yooj yim.Cov khoom siv raw ntawm PCB yog tooj liab clad laminate, uas yog cov khoom siv substrate los ua cov ntawv luam tawm hauv Circuit Court.Nws yog siv los txhawb ntau yam khoom, thiab tuaj yeem ua tiav kev sib txuas hluav taws xob lossis hluav taws xob rwb thaiv tsev ntawm lawv.Yooj yim muab tso, PCB yog ib lub rooj tsavxwm nyias nrog kev sib xyaw ua ke thiab lwm yam khoom siv hluav taws xob.Nws yuav tshwm sim hauv yuav luag txhua yam khoom siv hluav taws xob.
