Udinga abahlaziyi be-spectrum, izamukeli ze-EMI, izinti, nama-LISN. Lawa mathuluzi akala ukukhishwa kwekhabhoni nokuvikeleka. Isofthiwe yokuhlaziya idatha nokubika nayo yenza inqubo ibe lula.
Uyehlisa kanjani i-EMI kumklamo we-PCB?
Sebenzisa izindiza eziphansi, ama-capacitor e-decoupling, kanye nemizila efanele yokulandela umkhondo. Vikela izingxenye ezinomsindo futhi uzihlukanise kumasekhethi azwelayo. Lezi zinyathelo zinciphisa ukuphazamiseka futhi zithuthukise ukusebenza.
Kufanele ubuyekeze kangaki ulwazi lwakho lwezindinganiso zokuthobela?
Kufanele ugade izibuyekezo njalo. Amazinga ashintsha njalo, futhi ukuhlala unolwazi kuqinisekisa ukuthi umkhiqizo wakho uhlala uthobela. Bhalisela izibuyekezo zokulawula futhi ubambe iqhaza kumaforamu embonini.
Ithiphu: Amawebhusayithi okulawula ibhukhimakhi ukuze ufinyelele ngokushesha kuzibuyekezo nemihlahlandlela.
