Nrog kev txhim kho sai sai ntawm cov teb xws li 5g kev sib txuas lus, lub tshuab sib txuas lus satellite, thiab cov tshuab radar, qhov kev thov rauhigh - zausCov laug cam yog pom kev loj hlob tawg. Cov kev kub zog siab muaj cov yam ntxwv xws li Dielectric tas li (DF), kev ua kom muaj txiaj ntsig loj, thiab kev ua haujlwm tau zoo rau kev sib kis tau zoo thiab ua haujlwm ntawm siab.
1, cov ntsiab lus ntawm siab - zaus Pawg Thawj Coj
(1) Xaiv cov khoom
Cov kev ua tau zoo ntawm high - zaus boards loj nyob ntawm cov khoom xaiv. Tsawg DK thiab qes DF substrate cov ntaub ntawv yog qhov tseem ceeb, PTFE) thiab lwm yam khoom siv tau zoo, thiab lwm yam. Tsis tas li ntawd, hom ntawm tooj liab ntawv ci siv rau hauv tooj liab- cladper ntawv los cuam tshuam thiab siv cov paib liab qab sib txuas thiab txhim kho cov teeb liab zoo.
(2) Kev tswj yuam kev
Kev Impedance tswj yog ib qho ntawm cov ntsiab lus tseem ceeb kom ntseeg tau tias cov paib kev kis tau rau hauv high {{zaus} zaus.Print Circuities Board Cov Chaw Tsim TshuajXav tau kom muaj qhov tseeb thiab tswj cov yam ntxwv ntawm cov kab kis tau raws li cov yam ntxwv ntawm kev tsim cov ntsiab lus thiab cov qauv kev tsim qauv. Qhov no cuam tshuam nrog kev hloov kho kom zoo xws li kab dav, kab kab, dielectric thickness, thiab tooj liab ntawv ci ntawm Circuit Court. Los ntawm kev siv cov ntsiab lus yuam kom xam software thiab siab} precedance cuam tshuam txog kev sib tw me me, feem ntau yog kev cuam tshuam ntawm kev sib tw loj, txo cov kev xav txog thiab lub cim kev sib txawv.
(3) Tus Qauv Kev Nyab Xeeb
Txhawm rau kom muaj kev ncaj ncees ntawm high - Cov qauv teeb tsa, thiab hauv paus rau lub sijhawm cov ntawv luam tawm theem tsim. Kev tsim kho cov qauv txheej txheem ntawm cov teeb liab thiab cov pob zeb, tau txais cov teeb meem siv hluav taws xob ntau ntxiv rau cov paib, thiab txo cov crosstalk thiab sab nraud cuam tshuam ntawm cov cim. Nyob rau tib lub sijhawm, rau high - ceev cov xov tooj, kom tsis txhob muaj kev sib tw thiab hluav taws xob ua kom zoo thiab hluav taws xob, thiab ua kom muaj teeb liab zoo thiab ruaj khov.
2, Txheej Txheem Flow of High - zaus Pawg Thawj Coj
(1) Cov Ntaub Ntawv Engineering Ntau Lawm
Firstly, raws li cov schematic thiab luam tawm cov board tsim qauv tsim los ntawm cov qhua tuaj noj mov, tsim cov ntaub ntawv tsim tawm xws li cov ntaub ntawv gerber thiab drilling cov ntaub ntawv. Hauv cov txheej txheem no, nws yog ib qho tsim nyog yuav ua raws cov qauv tsim qauv thiab kev tswj hwm kev sib cav sib ceg, thiab ua kom muaj teeb meem kev tswj hwm kev ntseeg siab, yog qhov ua tau zoo thiab muaj kev ntseeg tau ntawm cov qauv tsim qauv.
(2) Sab hauv This Duab Ntau Lawm
Import cov ntaub ntawv tsim khoom siv mus rau sab hauv txheej txheej txheej txheem cov khoom siv ntau lawm, thiab hloov cov qauv tsim hauv lub taub hau {} clad board, kev loj hlob, thiab lwm yam txheej txheem. Thaum lub sij hawm kis tau kis tau, nws yog ib qho tseem ceeb kom ntseeg tau tias muaj kev sib xws thiab raug ntawm lub zog raug kom ntseeg tau qhov meej thiab precuitision ntawm Circuit Court. Tom qab kev loj hlob, lub Circuit Court yog etched kom tshem tawm ntau dhau ntawm tooj liab ntawv ci thiab ua ib qho txheej txheem sab hauv Circuit Court. Cov kauj ruam no yuav tsum tau tswj cov siab ua kom zoo, thiab kev sib txuas ntawm cov qauv hauv nruab sab hauv thiab kom muaj qhov chaw zoo ntawm Circuit Court yog qhov tsis muaj zog thiab tsis muaj qhov tsis muaj zog.
(3) cov txheej txheem lamination
Muab cov txheej txheem sab hauv board nrog semi cured ntawv, thiab tom qab ntawd}} {- txheej board qauv. Kev tswj kom sov, siab, thiab lub sijhawm yog qhov tseem ceeb hauv cov txheej txheem lamination, raws li cov kev sib tw ntawm cov txheej ntawm dient ntawm lub rooj tsavxwm. Kev ntsuas kub heev lossis lub zog yuav ua rau tuab cov txheej txheem ntawm cov txheej txheem nruab nrab, thaum muaj kev cuam tshuam tsis muaj zog, cuam tshuam rau cov kev ua tau zoo heev, cuam tshuam rau tag nrho cov kev ua tau zoo thiab kev ntseeg tau ntawm pawg thawj coj saib.
(4) sab nraud txheej txheem
Zoo ib yam li cov khoom lag luam nyob hauv txheej txheej, kev tsim cov txheej txheem txheej txheej sab nraud ntxiv rau cov thawj coj ntawm cov chaw xws li kis tau xws li kev sib tw xws li kev sib kis xws li kev sib kis xws li kev sib kis xws li kev sib kis xws li kev sib kis xws li kev sib tw xws li kev raug mob, thiab etching. Thaum lub sijhawm txheej txheem no, kev saib tshwj xeeb yuav tsum tau them rau cov txheej txheem sab hauv cov duab kom ntseeg tau tias yog cov sib txuas tau ntawm cov khaubncaws sab nraud povtseg. Nyob rau tib lub sijhawm, txhawm rau kom tau raws li qhov kev ua tau hluav taws xob xav tau, thiab siv cov nyiaj npib sab nraud, ua kom muaj kev sib raug zoo, ua kom muaj kev sib tw ua kom zoo dua qub, thiab cov khoom siv rau cov nyiaj sab nraud, ua kom muaj kev sib tw ua kom zoo dua qub, ua kom muaj kev sib tw ua kom zoo dua qub, ua kom muaj kev sib tw ua kom zoo dua qub, thiab siv cov teeb meem ntawm cov khoom siv rau cov khoom siv rau cov tshuaj lom neeg, kom muaj kev sib tw ua kom zoo dua qub, thiab siv cov teeb meem ntawm cov khoom siv rau cov khoom noj kom zoo dua qub
(5) Drilling thiab qhov ntsuas
Raws li cov kev xav tau ntawm cov khoom siv tshuab ua haujlwm, siv cov khoom siv cnc drilling los xyaum los ntawm qhov, lub qhov muag tsis pom kev ntawm ntau yam {}} txheej pob. Thaum lub sij hawm drilling txheej txheem, nws yog ib qho tsim nyog los xyuas kom meej qhov tseeb ntawm lub qhov, thiab tsis txhob muaj teeb meem xws li kev sib txawv, lossis apertently txawv txawv. Tom qab kev xyaum ua tiav, lub qhov ntsa yuav tsum tau muab tso tawm, thiab ib qho khoom siv tooj liab los ua kom tiav cov hluav taws xob sib txuas ntawm cov khaubncaws sab nraud ntawm cov txheej txheem. Qhov zoo ntawm qhov metallization ncaj qha cuam tshuam qhov kev ua tau zoo thiab kev ntseeg tau ntawm qhov kev ntsuas tooj liab plaw, yog li nws yog cov khoom siv tooj liab, thiab cov nplaum ntawm lub khawm tooj liab ua tau raws li qhov yuav tsum tau ua.
(6) kev kho kom zoo nkauj thiab kev sib sau ua ke
Tom qab ua tiav drilling thiab qhov me me me me, qhov siab - cov tshuaj Nickel plating, nyiaj txau thiab lwm yam txheej txheem hais ua ntej. Cov qauv kev kho mob tsim nyog raug xaiv raws li cov kev xav tau ntawm cov qhua tuaj noj mov, tiv toj thiab kev tiv thaiv kev tiv thaiv hauv cov xwm txheej sib txawv. Tom qab ntawd, cov txwj laus loj tau txiav mus rau hauv cov kev xav tau me me los ntawm cnc gong tshuab, v}}} zaus board raws li cov kev cai. Yog li, ua tiav siab high - zaus Pawg Thawj Coj Ua tiav.
