合作企業最新人才需求公告

Cadence培訓高級班將首先讓您了解CB板上出現的信號反射、串擾、電源/地平面幹擾、時序匹配以及電磁兼容性等一系列問題産生的機理，並掌握其解決方法；然後講解並上機練習Cadence的高速 PCB設計與仿真工具SPECCTRAQuest的使用。使您在硬件設計過程中，能夠達到“設計即正確”的目的。

        在工作實踐中遇到了高速數字電路與高速PCB設計問題；對高速PCB設計感興趣的硬件工程師；已經具備一定的硬件開發經驗，需要增加就業競爭力的在校碩士及博士研究生；具備非常紮實的電子工程基本知識，並積累了相當程度的硬件工程師工作經驗的在校本科生。

        爲了保證培訓效果，增加互動環節，我們堅持小班授課，每期報名人數限5人，多余人員安排到下一期進行。

        1、培訓過程中，如有部分內容理解不透或消化不好，可免費在以後培訓班中重聽；
        2、培訓結束後免費提供一個月的技術支持，充分保證培訓後出效果；
        3、培訓合格學員可享受免費推薦就業機會。
