High zaus Circuit Court boardstau dhau los ua lub hauv paus tseem ceeb hauv thaj chaw xws li kev sib txuas lus, radar, thiab satellites. Nws qhov kev ua tau zoo ncaj qha txiav txim siab qhov ruaj khov, poob tus nqi, thiab kev ntseeg tau tag nrho ntawm cov teeb liab kis.
1, Cov yam ntxwv tshwj xeeb thiab daim ntawv thov scenarios ntawm siab - zaus Circuit Court boards
High zaus Circuit Court boards yog siv los xa cov teeb liab nrog zaus tshaj 1GHz, feem ntau pom nyob rau hauv 5G chaw nres tsheb, satellite kev sib txuas lus, radar systems, aerospace electronics, thiab lwm yam scenarios. Piv nrog rau cov rooj sib tham zoo tib yam, nws cov kev cuam tshuam kev lag luam feem ntau yog tshwm sim hauv peb qhov ntsuas tseem ceeb:
Tsawg dielectric tsis tu ncua thiab tsis tshua muaj qhov poob
Nyob rau hauv siab -frequency signal kis tau tus mob, qhov dielectric qhov tsis tu ncua ntawm cov khoom siv dielectric ncaj qha cuam tshuam rau lub teeb liab ceev, thaum qhov poob qhov tseem ceeb txiav txim siab qib ntawm lub zog attenuation. Piv txwv li, hauv 5G millimeter yoj kev sib txuas lus, yog tias lub teeb liab zaus tshaj 28GHz thiab Dk tus nqi ntawm cov khoom siv hluav taws xob hluav taws xob hloov pauv los ntawm 0.1, lub teeb liab qeeb yuam kev yuav nthuav mus rau qib nanosecond, uas yuav ua rau kev sib txuas lus tsis ua haujlwm. Yog li ntawd, siab - zaus Circuit Court boards yuav tsum tau siv tshwj xeeb substrates xws li polytetrafluoroethylene thiab kua siv lead ua polymers, nrog rau Dk tus nqi feem ntau tswj ntawm 2.2-3.5 thiab Df hauv qab 0.001.
High precision machining technology
High zaus Circuit Court boards feem ntau integrate ntau - txheej txheej (feem ntau 6-20 txheej), thiab cov kab dav / kab sib nrug qhov tseeb yuav tsum tau qis dua 50 μ m, nrog rau qhov muag tsis pom / faus lub qhov taub me me li 0.1 hli. Ua piv txwv array radar kav hlau txais xov modules ua piv txwv, lub rooj tsav xwm hauv Circuit Court yuav tsum tau siv ntau txhiab kab microstrip nyob rau hauv 10cm ² cheeb tsam, thiab ua tiav interlayer interconnection los ntawm laser drilling thiab plasma etching txheej txheem, nrog kev ua yuam kev kam rau tsawg dua 1/10 ntawm txoj kab uas hla ntawm tib neeg cov plaub hau.
ib puag ncig stability
Nyob rau hauv ib puag ncig huab cua xws li aerospace, siab - zaus Circuit Court boards yuav tsum tau tiv taus kub shocks xws li -55℃mus rau +125 degree, thiab rwb thaiv tsev kuj yuav tsum tsis txhob tsawg tshaj li 10G Ω nyob rau hauv 95% RH av noo tej yam kev mob. Qhov no yuav tsum muaj cov tuam txhab tsim khoom los tsim cov txheej txheem tshwj xeeb xws li lub tshuab nqus tsev thiab txheej txheej (xws li electroless npib tsib xee plating) txhawm rau txhim kho corrosion thiab deformation tsis kam ntawm substrate.
2, Cov kev sib tw tseem ceeb ntawm siab - zaus Circuit Court board ntau lawm
Kev tsim cov siab- zaus Circuit Court boards yog ib qho kev siv tshuab siv ntau yam uas muaj ntau yam kev kawm xws li cov ntaub ntawv science, electronic engineering, thiab precision manufacturing. Cov teeb meem tseem ceeb suav nrog:
Kev xaiv substrate thiab sib txuam
Muaj qhov sib txawv tseem ceeb hauv cov txheej txheem substrate rau cov xwm txheej sib txawv. Piv txwv li, 2.4GHz Wi Fi cov khoom siv tuaj yeem siv FR-4 epoxy iav ntaub substrate (Dk ≈ 4.4), thaum 60GHz millimeter yoj radar yuav tsum siv Rogers RT/duroid ® 5880 (Dk=2.2) lossis TaconicTLY ™ Series cov ntaub ntawv. Cov tuam txhab tsim khoom yuav tsum tsim kom muaj ntau pawg substrate database thiab ua cov kev sim xws li kev sim dielectric tas li thiab thermal expansion coefficient txuam los xyuas kom muaj kev sib raug zoo ntawm cov ntaub ntawv thiab cov qauv tsim.
Teeb pom kev ncaj ncees tsim
Cov teeb liab ntau zaus raug cuam tshuam rau yam xws li cov nyhuv ntawm daim tawv nqaij thiab electromagnetic coupling, ua rau cov teeb liab distortion. Cov tuam txhab tsim khoom yuav tsum tau koom tes nrog cov neeg siv khoom txhawm rau txhim kho cov txheej txheem sib dhos, xws li siv cov khoom siv hluav taws xob / inductor tsim, sib txawv teeb liab thaiv, thiab lwm yam thev naus laus zis. Nyob rau tib lub sijhawm, simulation software yuav tsum tau siv los kwv yees kev poob thiab tswj qhov rov qab poob qis dua -20dB thiab tso qhov poob qis dua 0.5dB / hauv.
Txheej txheem tswj kev sib xws
Siv cov txheej txheem tshuaj tooj liab deposition ua piv txwv, qhov sib xws ntawm tooj liab thickness ntawm lub qhov phab ntsa ntawm siab - zaus Circuit Court boards yuav tsum tau tswj nyob rau hauv ± 5%. Yog hais tias lub zos thickness tsis txaus, nws yuav ua rau muaj teeb meem xav txog. Cov kab ntau lawm yuav tsum tau nruab nrog cov khoom siv hauv online AOI thiab X-ray thickness gauges los saib xyuas cov kev hloov pauv ntawm qhov aperture thiab txheej thickness ntawm lub sijhawm, kom ntseeg tau tias cov khoom lag luam ruaj khov.
