Hauv peb lub neej niaj hnub, peb tuaj yeem pom cov khoom siv hluav taws xob nyob txhua qhov chaw. Raws li cov neeg nyiam siv hluav taws xob digital, peb txhua tus paub tias cov khoom siv hluav taws xob tuaj yeem ua haujlwm, sab hauv yog cov motherboard, lub motherboard yog them nrog ntau qhov ntau thiab tsawg, cov cai ntawm ntau qhov sib txawv ntawm cov khoom siv hluav taws xob, tom qab ntawd lub motherboard kev tshaj lij hu ua PCBA. los ntawm smt thiab DIP ua, thiab them nrog ntsuab lossis xiav lossis liab lub rooj tsavxwm, kev lag luam txoj haujlwm hu ua PCB, hnub no peb yuav muab rau koj SMD kev lag luam, pcb sib txawv board txheej ntawm qhov sib txawv thiab lub luag haujlwm.
Lub rooj tsav xwm ua haujlwm, yuav tsum tau ua tom qab SMT thiab ua tiav, lub rooj tsavxwm liab qab yog PCB, thiab tsis txaus siab rau cov khoom ntawm lub rooj tsavxwm yog hu ua PCBA. PCB kuj yog ib yam khoom siv hluav taws xob, tab sis PCB zoo li tsim lub hauv paus hauv tsev, thiab PCB sib txawv kuj muaj cov txheej txheem sib txawv, feem ntau yog 2 txheej, 4 txheej, 6 txheej, 8 txheej, 16 txheej, 32 txheej, thiab lwm yam. ., qee qhov Complex pcb tuaj yeem muaj ntau pua pua txheej, qhov pcb no hauv cov khoom siv hluav taws xob niaj hnub yog qhov nyuaj rau pom, peb pom hauv peb lub neej niaj hnub lub rooj tsavxwm yog qhov pib 4- txheej thiab ob txheej. Hnub no, peb yuav piav qhia txog 4- txheej thiab ob txheej txheej PCB board.
Yuav ua li cas txheeb xyuas ntawm ib nrais muag yog lub rooj tsav xwm multilayer lossis ob txheej txheej board
Cov txheej txheem
1. multilayer board Circuit Court kev twb kev txuas yog los ntawm qhov faus qhov thiab qhov muag tsis pom kev thev naus laus zis, 4- txheej board yog thawj, plaub txheej sib dhos, lwm cov txheej hauv av thiab lub zog.
2. Los ntawm lub qhov los txheeb xyuas, lossis siv lub teeb nyem kom ci hauv qab no, saib qhov kev xav ntawm lub qhov saum toj no, ntau lub rooj tsav xwm hauv qhov khoob tab sis tsis yog los ntawm lub teeb tawm.
3. Saib ntawm PCB sab saum toj thiab hauv qab cov khaubncaws sab nraud povtseg ntawm cov khaubncaws sab nraud povtseg, nruab nrab ntawm ob txheej yog ib tug plaub-txheej board, nruab nrab ntawm plaub txheej yog ib tug rau-txheej board.
Vim li cas cov khaubncaws sab nraud povtseg ntawm pcb ntau dua cov khaubncaws sab nraud povtseg?
1. Lub rooj tsav xwm tseem ceeb feem ntau yog ob sab ntawm tooj liab cladding.
2. Yog tias koj xav ua cov txheej txheem khib nyiab, nws tsis yog txheej txheem lamination, khib-txheej PCB cov nqi ua haujlwm ntau dua li cov txheej txheem PCB, tib cov nqi ua haujlwm ntawm txheej sab hauv; tab sis ho nce tus nqi ua ntawm txheej txheej.
3. loj loj ntawm ib txheej warpage yog ib qho yooj yim kom dhau tus qauv, yog li kev ua haujlwm yog nqa tawm raws li tus naj npawb ntawm cov khaubncaws sab nraud povtseg, txawm tias tus naj npawb ntawm cov khaubncaws sab nraud povtseg yooj yim dua los tswj cov board dabtsi yog khoov.
4. Yog tias koj ua cov txheej khib nyiab, koj yuav tsum tau nce cov txheej hauv av, yog li lub teeb liab kev ncaj ncees tsis zoo.
Ob txheej txheej board thiab 4- txheej board qhov zoo thiab qhov tsis zoo
Ob txheej txheej board thiab 4- txheej board uas yog superior thiab leej twg yog inferior tsis zoo los sib piv, qhov no raws li qhov tseeb xav tau los txiav txim;.
Plaub-txheej board yog ua raws li lub rooj tsavxwm ob txheej thiab tom qab ntawd nias ua ke, nias ua ke thaum ob sab ntawm lub rooj tsavxwm ob txheej tau ntxiv PP thiab tooj liab ntawv ci, thiab tom qab ntawd nias rau hauv 4- txheej board tom qab siab. kub thiab siab, plaub-txheej board muaj ib txheej sab hauv, thaum lub ob-txheej board tsis muaj ib tug puab txheej, plaub-txheej board thaiv ntom ntom yog txo, thaiv yooj yim dua, tab sis kub dissipation yog txo, tus nqi nce, thaum lub ob-txheej board ncaj qha txiav cov khoom siv hauv pawg thawj coj tuaj yeem ua tom qab drilling.
Yog li ntawd, lub rooj tsavxwm ob txheej yog qhov yooj yim, tus nqi qis dua, tsim nyog rau kev siv cov khoom siv yooj yim, thaum lub rooj tsavxwm multilayer kim dua los tsim, lub voj voog ntev dua, rau ntau qhov nyuaj, yuav tsum muaj kev ntseeg siab dua ntawm cov khoom siv hluav taws xob.
