Tus yuam sij rau optimizing impedance tswj ntawm lubrigid flex printed circuit boardsnyob rau hauv peb txoj hauv kev ntawm kev xaiv cov khoom siv, kev tswj cov txheej txheem, thiab tsim simulation:
Cov ntaub ntawv yog lub hauv paus
Ua ntej sivsiab - zaussubstrates nrog qis dielectric tas li (Dk) thiab qhov poob qis (Df), xws li Panasonic MEGTRON6 lossis Isola FR408HR, uas tuaj yeem txo cov teeb liab attenuation. Lub caij no, ultra-thin copper foil (tsawg dua lossis sib npaug li 12 μ m) kuj pab txo qis kev sib kis.
Txheej txheem txiav txim qhov tseeb
nruj me ntsis tswj cov txheej txheem etching kom ntseeg tau qhov sib xws hauv kab dav / qhov sib txawv yog tus yuam sij kom txo qis impedance hloov pauv. Thaum lub sij hawm lamination, nws yog ib qho tsim nyog yuav tsum tswj xyuas qhov tuab ntawm nruab nrab kom tsis txhob muaj qhov sib txawv ntawm tus nqi tiag tiag thiab tus nqi tsim vim qhov sib txawv ntawm cov txheej txheem lamination.
Tsim simulation ua ntej
Siv cov kev tshaj lij software thiab lwm yam 3D electromagnetic teb simulation cov cuab yeej los simulate teeb liab kev ncaj ncees thiab optimize hlau topology thaum lub sij hawm layout. Rau cov kab sib txawv, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov cuam tshuam sib txuas tuaj yeem txo qhov sib txawv impedance thiab tsis tuaj yeem xam tau yooj yim raws li ob zaug ntawm ib qho kawg impedance.
