3.輻射騷擾傳導騷擾相關問題的改進建議

(1) 在zai設she計ji階jie段duan要yao充chong分fen考kao慮lv電dian磁ci兼jian容rong特te性xing
，合he理li考kao慮lv電dian路lu板ban的de接jie地di設she計ji
，應ying保bao持chi接jie地di環huan路lu盡jin量liang小xiao
，使shi用yong網wang格ge接jie地di，信xin號hao線xian或huo電dian源yuan線xian盡jin量liang與yu地di線xian靠kao近jin。設she計ji過guo程cheng中zhong，對dui充chong電dian器qi和he手shou機ji的de充chong電dian端duan口kou采cai取qu濾lv波bo措cuo施shi，對dui輻fu射she發fa射she敏min感gan元yuan器qi件jian采cai取qu屏ping蔽bi措cuo施shi，增zeng加jia屏ping蔽bi罩zhao;

(2) 選擇質量好，電磁兼容特性好的元器件;

(3) 優化器件的位置、bujuhebuxian，qijianbujuyizhianzhaogongnengheqijianleixinglaiduiyuanqijianjinxingfenzu，liru，duijicunzaimonidianlu

，monidijintiemonidianyuanceng，monidiheshuzidiyaoyouyigegongdidian。tongchang
，dianluzhongcunzaiA/D或D /A器件，這些轉換器件jian同tong時shi由you模mo擬ni和he數shu字zi電dian源yuan供gong電dian
，因yin此ci要yao將jiang轉zhuan換huan器qi放fang置zhi在zai模mo擬ni電dian源yuan和he數shu字zi電dian源yuan之zhi間jian。果guo數shu字zi地di和he模mo擬ni地di是shi分fen開kai的de，它ta們men將jiang在zai轉zhuan換huan器qi彙hui合he。當dang電dian路lu板ban按an照zhao器qi件jian係xi列lie和he電dian源yuan電dian壓ya分fen組zu時shi，組zu內nei信xin號hao的de傳chuan送song不bu能neng跨kua越yue另ling外wai的de器qi件jian組zu，如ru果guo信xin號hao跨kua過guo界jie限xian

，就jiu不bu能neng與yu其qi回hui流liu路lu徑jing緊jin密mi耦ou合he
，這zhe樣yang會hui增zeng大da電dian路lu的de環huan路lu麵mian積ji
，從cong而er使shi電dian感gan增zeng加jia，電dian容rong減jian小xiao
，進jin而er導dao致zhi共gong模mo和he差cha模mo幹gan擾rao的de增zeng加jia。電dian路lu板ban設she計ji過guo程cheng中zhong要yao避bi免mian出chu現xian各ge種zhong隔ge離li帶dai。雖sui然ran相xiang距ju很hen近jin的de一yi排pai通tong孔kong並bing不bu違wei反fan設she計ji規gui則ze，但dan是shi
，在zai電dian源yuan層ceng和he地di層ceng上shang過guo多duo的de通tong孔kong有you時shi相xiang當dang於yu開kai出chu一yi條tiao隔ge離li帶dai

，要yao避bi免mian在zai該gai區qu域yu內nei布bu線xian，例li如ru，當dang一yi個ge3ns的信號回路如果偏離其信號源路徑0.40英寸，則過衝/欠衝和感生串擾會大增
，足以使電路工作出現異常，並同時增加差模和共模幹擾。

綜上所述，對於輻射騷擾和傳導騷擾，應把握以下原則：

注重設計階段的電磁兼容設計;

注重充電器和手機的匹配;

選擇優良的元器件。
