hnyav tooj liab pcb 4 Txheej (4/4/4/4OZ) Dub Soldermask Board| YMS PCB

Qhov hnyav tooj liab PCB yog dab tsi?

Qhov PCB classic no yog thawj qhov kev xaiv thaum muaj qhov siab tam sim no tsis tuaj yeem zam: cov tuab tooj liab PCB , tsim los ntawm cov cuab yeej etching tiag. Thick tooj liab PCBs yog tus cwj pwm los ntawm cov qauv nrog tooj liab thicknesses ntawm 105 mus rau 400 µm. Cov PCBs no yog siv rau qhov loj (siab) cov zis tam sim no thiab rau kev ua kom zoo ntawm kev tswj xyuas thermal. Cov tooj liab tuab tso cai rau PCB loj-hloov-ntu rau kev thauj khoom siab tam sim no thiab txhawb kom muaj cua sov dissipation. Cov qauv tsim feem ntau yog multilayer lossis ob sab. 

Thaum tsis muaj tus qauv txhais ntawm Heavy Copper, nws feem ntau lees txais tias yog 3 ooj (oz) tooj liab lossis ntau dua yog siv rau ntawm cov txheej txheem sab hauv thiab sab nraud ntawm lub rooj tsav xwm luam tawm, nws yog hu ua hnyav tooj liab PCB . Txhua lub voj voog uas muaj tooj liab tuab ntawm ntau tshaj 4 oz ib square feet (ft2) kuj tau categorized li hnyav tooj liab PCB. Cov tooj liab heev txhais tau tias 20 oz ib ft2 rau 200 oz ib ft2.

Ib qho hnyav tooj liab PCB raug txheeb xyuas raws li PCB nrog cov tooj liab tuab 3 oz ib ft2 txog 10 oz ib ft2 nyob rau hauv cov txheej txheej sab nrauv thiab sab hauv. Ib qho hnyav tooj liab PCB yog tsim nrog tooj liab hnyav li ntawm 4 oz ib ft2 txog 20 oz ib ft2. Kev txhim kho tooj liab qhov hnyav, nrog rau cov plating tuab thiab tsim nyog substrate nyob rau hauv qhov los ntawm qhov tuaj yeem hloov lub rooj tsavxwm tsis muaj zog rau hauv lub kav hlau ntev ntev thiab muaj kev ntseeg siab. Hnyav tooj liab conductors tuaj yeem ua rau tag nrho PCB thickness ntau. Lub thickness tooj liab yuav tsum tau txiav txim siab thaum lub sij hawm tsim Circuit Court. Lub peev xwm nqa tam sim no yog txiav txim siab los ntawm qhov dav thiab tuab ntawm cov tooj liab hnyav.

Cov txiaj ntsig tseem ceeb ntawm cov rooj sib tham tooj liab hnyav yog lawv lub peev xwm kom muaj sia nyob tau raug cuam tshuam ntau dhau tam sim no, qhov kub thiab txias rov ua dua, uas tuaj yeem rhuav tshem lub rooj tsav xwm tsis tu ncua hauv vib nas this. Lub rooj tsav xwm tooj liab hnyav muaj peev xwm ua siab ntev, uas ua rau nws sib haum nrog cov ntawv thov hauv cov xwm txheej ntxhib xws li, kev tiv thaiv thiab cov khoom lag luam aerospace.

Qee qhov txiaj ntsig ntxiv ntawm hnyav tooj liab Circuit Court boards yog:

Cov khoom loj me me vim muaj ntau qhov hnyav tooj liab ntawm tib txheej ntawm circuitry

Hnyav tooj liab-plated vias dhau qhov siab tam sim no los ntawm PCB thiab pab hloov cov cua sov mus rau lub dab dej sab nraud

Qhov sib txawv ntawm Standard PCB thiab Thick Copper PCB

Txheem PCBs tuaj yeem tsim nrog tooj liab etching thiab plating txheej txheem. Cov PCBs no yog plated los ntxiv tooj liab tuab rau cov dav hlau, kab, PTHs, thiab cov ntaub qhwv. Tus nqi ntawm tooj liab siv hauv kev tsim cov qauv PCBs yog 1oz. Hauv kev tsim cov tooj liab hnyav PCB, cov tooj liab siv ntau dua 3oz.

Rau cov qauv Circuit Court boards, tooj liab etching thiab plating txheej txheem yog siv. Txawm li cas los xij, hnyav tooj liab PCBs yog tsim los ntawm kev sib txawv etching thiab kauj ruam plating. Cov txheej txheem PCBs ua haujlwm sib zog thaum cov tooj liab hnyav ua haujlwm hnyav.

Txheem PCBs ua tam sim no qis dua thaum hnyav tooj liab PCBs ua tam sim no dua. Thick tooj liab PCBs yog qhov zoo tagnrho rau kev siv high-end vim lawv cov thermal faib tau zoo. Hnyav tooj liab PCBs muaj zog txhua yam zoo dua li cov qauv PCBs. Hnyav tooj liab Circuit Court boards txhim khu lub peev xwm ntawm lub rooj tsavxwm uas lawv tau siv.

Lwm cov nta uas ua rau tuab tooj liab PCBs txawv ntawm lwm cov PCBs

Copper hnyav: Qhov no yog qhov txawv feature ntawm hnyav tooj liab PCBs. Copper hnyav yog hais txog qhov hnyav ntawm tooj liab siv nyob rau hauv ib square feet. Qhov hnyav no feem ntau ntsuas hauv ounces. Nws qhia txog tooj liab lub thickness ntawm txheej.

Cov txheej txheej sab nraud: Cov no xa mus rau cov txheej tooj liab sab nraud ntawm lub rooj tsavxwm. Cov khoom siv hluav taws xob feem ntau yog sib txuas nrog cov txheej txheem sab nraud. Cov txheej sab nraud pib nrog cov ntawv ci tooj liab uas yog coated nrog tooj liab. Qhov no yuav pab kom cov tuab tuab. Qhov hnyav tooj liab ntawm cov khaubncaws sab nraud povtseg yog preset rau cov qauv tsim. Hnyav tooj liab PCB chaw tsim tshuaj paus tuaj yeem hloov qhov hnyav thiab tuab ntawm tooj liab kom haum rau koj qhov kev xav tau.

Sab hauv cov khaubncaws sab nraud povtseg: Lub dielectric thickness, nrog rau cov tooj liab loj ntawm cov khaubncaws sab nraud povtseg, yog predefined rau tus qauv tej yaam num. Txawm li cas los xij, qhov hnyav ntawm tooj liab thiab tuab hauv cov khaubncaws sab nraud povtseg tuaj yeem hloov kho raws li koj xav tau.

Hnyav tooj liab PCBs yog siv rau ntau lub hom phiaj xws li nyob rau hauv planar transformers, tshav kub dissipation, siab zog tis, lub hwj chim converters, thiab lwm yam. Muaj kev xav tau ntau ntxiv rau hnyav tooj liab-clad boards hauv computer, tsheb, tub rog, thiab kev lag luam tswj.

Heavy tooj liab luam ntawv Circuit Court boards kuj siv nyob rau hauv:

Cov khoom siv hluav taws xob, hluav taws xob converters

Fais fab kev faib tawm
