Nyob rau tib lub sijhawm, kev mloog yuav tsum tau them rau cov kev taw qhia ntawm lub teeb liab, thiab lub teeb liab suab yuav tsum ntws ncaj nraim los ntawm cov tswv yim mus rau cov zis ntau li ntau tau, txo qhov muaj peev xwm ntawm teeb liab distortion los ntawm kev txo cov teeb liab folding thiab hla. Tsis tas li ntawd, kev tsim hauv av kuj yog ib feem tseem ceeb ntawm kev tsim layout. Lub hauv paus zoo hauv av tuaj yeem cuam tshuam cov suab nrov thiab txhim kho cov teeb liab purity. Feem ntau, ib qho taw tes hauv av lossis ntau- taw tes grounding yog siv, thiab kev xaiv yog raws li cov qauv hauv Circuit Court thiab kev ua haujlwm.
(2) Kev xaiv cov khoom siv: tso lub hauv paus rau kev ua haujlwm ntawm Circuit Court boards
Cov khoom siv ntawm lub rooj tsav xwm Circuit Court ncaj qha cuam tshuam rau nws cov kev ua haujlwm hluav taws xob, kev ua haujlwm zoo, thiab kev ua haujlwm kub dissipation. Cov khoom siv dav dav rau cov khoom siv hluav taws xob muaj xws li tooj liab- clad laminates, uas tuaj nyob rau hauv ntau hom xws li ntawv-raws li tooj liab- clad laminates, iav ntaub raws li tooj liab-clad laminates, thiab polytetrafluoroethylene tooj liab- clad laminates. Cov khoom sib txawv muaj cov yam ntxwv sib txawv thiab tsim nyog rau cov xwm txheej sib txawv. Piv txwv li, iav ntaub raws li tooj liab- clad laminates muaj lub zog txhua yam thiab hluav taws xob ua haujlwm, ua rau lawv tsim nyog rau lub hwj chim amplifier circuit boards uas yuav tsum tau muaj kev ntseeg siab; PTFE coated tooj liab phaj muaj qhov ua tau zoo heev - zaus ua haujlwm thiab tsim nyog rau siab - zaus fais fab amplifier circuits. Tsis tas li ntawd, lub thickness thiab tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm lub rooj tsavxwm Circuit Court kuj yog ib qho tseem ceeb hauv kev xaiv cov khoom siv. Thicker circuit boards muaj kev txhawb zog txhua yam thiab muaj peev xwm ua kom sov, ua rau lawv haum rau siab - fais fab amplifier systems; Multilayer circuit boards tuaj yeem txhim kho qhov sib txuas ntawm qhov ceev thiab teeb liab kev ncaj ncees ntawm lub rooj tsav xwm hauv Circuit Court los ntawm qhov tsim nyog interlayer layout, ua rau lawv tsim nyog rau cov khoom siv hluav taws xob sib txuas hluav taws xob.
3, Kev cuam tshuam kev ua haujlwm: Yuav ua li cas Circuit Court boards ua lub suab zoo ntawm amplifiers
Kev ua tau zoo ntawm lub amplifier Circuit Board ncaj qha cuam tshuam rau lub suab zoo ntawm lub amplifier. Cov khoom siv hluav taws xob zoo tshaj plaws tuaj yeem muab qhov chaw ruaj khov thiab dawb huv rau kev ua kom lub suab nrov nrov, ua rau lub suab pom meej dua, muag heev, thiab ntau txheej txheej. Ntawm qhov tsis sib xws, Circuit Court boards uas tsis tsim nyog tsim los yog cov khoom siv tsis zoo tuaj yeem ua rau lub suab nrov, distortion, thiab lwm yam teeb meem, ua rau lub suab tsis meej thiab nrov, cuam tshuam rau kev mloog.
