Dab tsi yog hom tseem ceeb ntawm PCB Circuit Boards

Tam sim no muaj ob txoj hauv kev los faib cov PCBs, ib qho yog cov txheej txheem, thiab lwm qhov yog qhov nyuaj.

Muab faib los ntawm tus naj npawb ntawm cov txheej tooj liab ntawv:

PCB tuaj yeem muab faib ua ib qho -sab, ob -sab thiab ntau- txheej boards. Feem ntau, ntau- txheej boards yog 4-txheej lossis 6-txheej pawg thawj coj saib, thiab qee lub rooj tsavxwm nyuaj yuav muaj kaum ob txheej.

Ib leeg -ib sab PCB yog PCB yooj yim tshaj plaws. Raws li lub npe qhia, nws cov xov hlau yog tsom rau ntawm ib sab, thaum cov khoom nyob rau sab nraud, txawm li cas los xij, SMT qhov chaw yuav nyob rau tib sab nrog cov xov hlau. Vim tias ib qho -sab pawg thawj coj yog txwv los ntawm thaj chaw hauv kev tsim, feem ntau ntawm qhov no tsuas yog siv tau rau cov kab hluav taws xob yooj yim xwb. Cov khoom siv hluav taws xob thaum ntxov lossis cov khoom siv hluav taws xob ib txwm muaj nrog kev hloov pauv tsawg dua feem ntau nrog ib leeg - sab laug.

Muab ob npaug rau-sab pawg thawj coj saib muaj cov xov hlau ntawm ob sab saum toj thiab hauv qab txheej, thiab txuas nrog los ntawm qhov. Yog li ntawd, ob npaug -sab pawg thawj coj saib ntawm tib qhov loj yuav muaj ob npaug ntawm cov xaim tsim cheeb tsam dua li ib qho - sab board. Uas daws qhov teeb meem ntawm kev cuam tshuam ntau dhau ntawm electromagnetic cuam tshuam los ntawm kev sib cuam tshuam ntawm cov xov hlau hauv ib qho - sab vaj huam sib luag, yog li nws tsim nyog rau kev tsim thiab kev siv ntau dua.

LED industrial lights are mostly with single-sided boad for cost reasons and  LED lighting products are with relatively simple circuit.

Multilayer boards yog ib leeg thiab ob -sab laug boards siv ua ke los ua kom cov kab txuas ntxiv. Feem ntau, ob ob - txheej boards yog siv los ua lub rooj tsavxwm sab hauv, tom qab ntawd ob zaug - txheej boards yog siv rau sab nrauv, thiab tom qab ntawd plaub- txheej txheej txheej txheej yog tsim los ntawm combining nrog ib tug positioning system thiab ib tug insulating bonding khoom.

Classified raws li hardness:

Nws tuaj yeem muab faib ua PCB nruj, yoog raws PCB thiab nruj -flex PCB.

Lub thickness ntawm lub rooj tsavxwm nruj feem ntau yog nyob ntawm {{0}}.2mm txog 2.0mm

Lub thickness ntawm lub rooj tsavxwm hloov tau yog feem ntau yog 0.2 hli, thiab nws yog thickened qhov twg nws yuav tsum tau soldered. Cov tsos ntawm cov boards hloov tau yooj yim yog feem ntau yog vim qhov txwv qhov chaw ntawm lub tshuab, rau nws yuav tsum tau siv ib tug bendable PCB kom tau raws li qhov yuav tsum tau ntawm qhov chaw. Cov khoom siv hluav taws xob hloov tau yooj yim feem ntau yog polyester zaj duab xis, polyimide zaj duab xis thiab fluorinated ethylene propylene zaj duab xis thiab lwm yam;

Lub nruj-flex PCB yog lub rooj tsav xwm hauv Circuit Court nrog FPC cov yam ntxwv thiab cov yam ntxwv ntawm PCB, uas yog tsim los ntawm lub rooj tsavxwm hloov tau yooj yim thiab cov khoom siv hluav taws xob nruj tswj xyuas hauv qab nias thiab lwm yam txheej txheem.
