8 Txheej FR4 ENIG Impedance Control PCB
Impedance yog kev sib xyaw ntawm capacitance thiab inductance los cuam tshuam lub Circuit Court nyob rau hauv siab zaus teeb liab.Impedance yog AC yam ntxwv, uas txhais tau hais tias nws yog nyob ntawm zaus.Nyob rau hauv cov ntaub ntawv ntawm kis high-frequency signals, tswj impedance pab kom paub tseeb tias tsis muaj ib tug tseem ceeb attenuation ntawm lub teeb liab thaum lub sij hawm kis tau tus mob.Hauv cov ntsiab lus, kev tswj impedance txhais tau hais tias cov yam ntxwv ntawm cov khoom siv ntawm lub substrate sib phim cov yam ntxwv ntawm cov kab / dielectric txheej kom ntseeg tau tias tus nqi impedance ntawm kab teeb liab yog nyob rau hauv qhov kam rau ntawm tus nqi siv.
Manufacturing Experience nyob rau hauv Impedance Control Field
Impedance Modeling Software Thiab Impedance Test Hardware
HUIHE Circuits siv impedance qauv software thiab impedance kuaj kho vajtse kom ua tau raws li koj cov kev cai tswj impedance.Polar's "speedstack" thiab "CITS" cov cuab yeej ua ke ua ke cov kev daws teeb meem zoo thiab cov khoom siv hauv tsev qiv ntawv los xyuas kom meej tias koj tus qauv tsim tuaj yeem ua tiav ib zaug thiab rau tag nrho.
Kev Tshawb Fawb Kev Lag Luam thiab Kev Tswj Xyuas Khoom Muag Khoom
Hauv kev koom tes nrog cov neeg muag khoom loj, cov txheej txheem pub mis ua kom zoo ib yam nrog cov khoom siv raw (laminates, PP, tooj liab ntawv ci).
Laser Direct Imaging Khoom
Cov khoom siv LDI zam cov kab dav hloov pauv vim yog cov yeeb yaj kiab qhuav nthuav dav / kev sib cog lus, thiab tib lub sijhawm ua kom pom cov duab meej dua ntawm cov tooj liab, uas ua rau muaj qhov tseeb dua hauv kab etching.
Etching Equipment Configuration
Thaum lub impedance tswj PCB tau raug nthuav tawm nws yuav tsum tau muab tso rau hauv lub tshuab etching rau etching.Lub etcher yuav tsum raug teeb tsa qhov tsis xws li ceev, qhov kub thiab txias, siab, kev taw qhia nozzle thiab lub kaum sab xis kom txo qis sab yaig.Nrog ntau xyoo ntawm kev paub hauv kev lag luam luam tawm Circuit Board, Hui He Circuit tau tsim cov txheej txheem etching kom paub meej tias cov neeg siv khoom xav tau kev tiv thaiv kev tiv thaiv nruj.
Cov yam ntxwv cuam tshuam rau impedance
Dielectric thickness:yog qhov tseem ceeb tshaj plaws cuam tshuam rau PCB luam ntawv boards impedance tus nqi
Kab dav / kab sib nrug:nce txoj kab dav kom txo tau qhov impedance, thiab txo txoj kab dav kom nce qhov impedance.
Copper thickness:txo cov kab thickness, nce impedance, nce kab thickness, thiab txo cov impedance
Dielectric tsis tu ncua:Ua kom lub dielectric tsis tu ncua tuaj yeem txo qhov impedance, thiab txo qhov dielectric tas li tuaj yeem ua rau qhov impedance.Lub dielectric tsis tu ncua yog tsuas yog tswj los ntawm cov khoom siv
Peb Qhov Zoo
1.Ntau tshaj 10 xyoo ntawm impedance manufacturing kev, nruj me ntsis tswj hlau dav thiab nruab nrab thickness
2. Standardize cov txheej txheem ntau lawm kom nruj impedance kam rau ua
3. Ua tiav cov ntawv pov thawj cov khoom thiab cov ntaub ntawv pov thawj ntawm lub Hoobkas
Cov khoom siv Display
Tsis Siv Neeg Plating Kab
PTH Kab
LDI
