Yuav ua li cas txiav txim siab qhov zoo ntawm ntau - txheej pcb Circuit Coffs los ntawm PCB xim. Niaj hnub no, peb yuav piav qhia rau koj qhov cuam tshuam ntawm pcb xim ntawm nws cov kev ua tau zoo. Yuav ua li cas peb thiaj txiav txim siab qhov zoo ntawm multi- txheej pcb Circuit Cochs.
Firstly, raws li cov ntawv luam tawm cov board, PCB feem ntau muab kev cuam tshuam nrog cov khoom siv hluav taws xob. Xim tsis yog ncaj qha cuam tshuam rau kev ua tau zoo, thiab cov xim sib txawv tsis muaj ntau qhov cuam tshuam rau kev ua hluav taws xob. Txawm li cas los xij, kev ua yeeb yam ntawm PCB cov laug cam xws li cov ntaub ntawv siv (siab Q tus nqi), cov qauv tsim, thiab cov naj npawb ntawm cov khaubncaws sab nraud povtseg. Nyob rau hauv tus txheej txheem ntawm kev ntxhua khaub ncaws PCBs, dub yog qhov muaj ntau heev rau xim txawv. Yog tias muaj kev sib txawv me ntsis nyob rau hauv cov ntaub ntawv raw thiab kev tsim cov txheej txheem siv los ntawm PCB pov thawj, nws yuav ua rau tus nqi PCB vim xim txawv. Qhov no ua rau muaj kev nce ntxiv hauv cov nqi ntau lawm.
Qhov tseeb, cov ntaub ntawv raw rau PCB feem ntau pom hauv peb lub neej txhua hnub, uas yog fiberglass thiab resin. Fiberglass tau sib xyaw ua ke nrog cov cob thiab tawv tawv kom dhau los ua pawg thawj coj uas yog insulated, insulated, thiab tsis yooj yim khoov, uas yog pcb substrate. Ntawm chav kawm, PCB substrates ua ib leeg ntawm cov iav fiber ntau thiab cov resin tsis tuaj yeem ua phiaj xwm. Yog li ntawd, ntawm pcb substrates, cov tuam ntxhab yuav them rau saum npoo hlau tooj liab, yog li pcb substtrates tseem tuaj yeem raug hu ua Copper {} clad substrates.
Vim tias qhov nyuaj hauv kev txheeb xyuas qhov Circuit Court xaim ntawm cov PCBS Dub, nws nce qhov nyuaj ntawm kev saib xyuas thiab debugging thaum lub sijhawm R & D thiab tom qab muag theem. Feem ntau, hom tsis muaj kev paub dhau (R & D) cov neeg tsim qauv thiab pab pawg saib xyuas muaj zog yuav tsis yooj yim siv cov PCbs yooj yim. Nws tuaj yeem hais tau tias siv PCB dub yog lub cim kev ntseeg siab ntawm cov neeg tsim khoom lag luam tawm thiab tsis ncaj ncees, nws tseem yog qhov ua kom muaj kev ntseeg siab ntawm lawv tus kheej lub zog.
Raws li cov laj thawj saum toj no, cov tuam ntxhab tseem ceeb yuav ua tib zoo txiav txim siab PCB lub rooj tsavxwm tsim thaum xaiv cov khoom lag luam. Yog li ntawd, nws tau tsim cov khoom lag luam feem ntau nrog cov pcb liab, thiab tsuas yog pcb lossis tsuas yog pcb lossis tsuas yog xim dub mus rau siab siab lossis sab saum toj {qib qib siab. Yog li ntawd, cov neeg siv yuav tsum tsis txhob xav txog cov pcbs dub zoo dua li cov packbs zoo dua li ntsuab pbs.
