Vim li cas Flexible Printed Circuit Boards yog tsim rau cov ntawv thov ntau zaus

Qhov kev thov rau cov ntawv luam tawm Circuit boards (PCBs) yog nce nrog kev txhim kho thev naus laus zis, thiab qhov kev xav tau ntau ntxiv thiab cov khoom siv me me tau nrawm rau daim ntawv thov ntawm PCB Circuit Board. Kev xaiv kom raug ntawm hom PCB Circuit Board yog tus yuam sij rau kev ua kom tiav thiab txhim khu kev qha cov khoom siv. Ntawm peb hom ntawv luam tawm Circuit Board rau kev siv ntau zaus, cov ntawv luam tawm yooj yim tau pom tias yog qhov kev xaiv zoo tshaj plaws.

Qhov zoo ntawm cov khoom siv PCB hloov tau

Muaj ntau ntau yam uas ua kom yooj yim luam tawm Circuit Court boards zoo tagnrho rau kev siv ntau zaus:

(1) Cov khoom siv Flex:

Cov ntawv thov ntau zaus yuav tsum tau ua raws li nyias-zaj duab xis Circuit Court txheej kom siv tau zoo dua. Yog li ntawd, nyob rau hauv lub tom ntej no txoj kev loj hlob ntawm Circuit Court boards, ntau hom ntawm hloov tau yooj yim polymer films tau los ua indispensable ntaub ntawv nyob rau hauv txoj kev loj hlob ntawm PCB Circuit Court boards. Cov yeeb yaj kiab no ua kom cov txheej nyias nyias thiab zoo ib yam, uas ua rau lawv xaiv qhov zoo tshaj plaws rau kev siv ntau zaus.

(2) Tooj:

Tib yam uas yuav tsum tau muaj nyob rau hauv cov txheej txheem tsim khoom ntse ntawm lub rooj tsav xwm hloov tau yooj yim yog qhov sib txawv ntawm cov rooj sib tham nruj nruj, uas yog ib qho ntawm cov laj thawj vim li cas thiaj li hloov tau cov ntawv luam tawm Circuit Court boards haum rau cov ntawv thov ntau zaus. Copper, ua los ntawm kev dhau ib qho loj ingot los ntawm ib tug series ntawm rolls, yog heev pab tau nyob rau hauv lub chaw tsim tshuaj paus ntawm saj zawg zog Circuit Court boards. Cov txheej txheem dov kuj nthuav dav thiab ua rau cov tooj liab, ua rau cov nplej loj tooj liab. Hauv daim ntawv thov kev hloov pauv hauv Circuit Court board, qhov loj loj loj ua rau tooj liab haum rau hom Circuit Court board. Tsis tas li ntawd, cov tooj liab txuas nrog cov khoom siv tau yooj yim los ntawm cov nplaum es tsis yog brazing, uas tuaj yeem tawg tau yooj yim.

(3) Dielectric: Qhov no yog lamination resin nrog zoo rwb thaiv tsev thiab conductivity. Lub dielectric muaj ib tug ceramic muab tub lim uas ua raws li ib tug nplaum thiab daim ntawv cog lus nrog cov ntawv ci tooj liab ntawm lub rooj tsavxwm hloov tau. Flexible printed circuit boards feem ntau yog tsim nrog epoxy lossis acrylic nplaum. Ntawm zaus tshaj 1 GHz, qhov txheeb ze permittivity ntawm ob qho tib si yog siab. Qhov no yog vim li cas cov ntaub ntawv hloov pauv tau siv rau kev siv ntau zaus vim lawv cov dielectric thickness.

Cov laj thawj saum toj no ua pov thawj tias cov khoom siv hluav taws xob hloov pauv hloov tau yog hom zoo tshaj plaws ntawm Circuit Court boards rau kev siv ntau zaus.

Qhov no yog laminating resin nrog zoo hluav taws xob conductivity thiab insulating zog. Lub dielectric muaj cov khoom siv ceramic, uas feem ntau yog siv los ua cov nplaum thiab siv dav hauv kev sib txuas nrog tooj liab foils ntawm lub rooj tsav xwm hloov tau yooj yim. Flexible Printed Circuit Boards Tsim los ntawm Epoxy lossis Acrylic Adhesives Yooj yim luam tawm Circuit Court boards muaj cov txheeb ze permittivity siab rau ob qho tib si ntawm ntau zaus tshaj 1 GHz. Qhov no yog vim li cas cov ntaub ntawv hloov pauv tau siv rau kev siv ntau zaus vim lawv cov dielectric thickness.

Cov laj thawj saum toj no ua pov thawj tias cov khoom siv hluav taws xob hloov pauv hloov tau yog hom zoo tshaj plaws ntawm Circuit Court boards rau kev siv ntau zaus.
