日前,由深圳市專家高新科技有限公司組織的科學技術成果鑒定會在深圳市舉行,鑒定專家評審委員會認為,博敏電子的“高頻寬微帶隔離器基板關鍵技術及產品”專案具有國內領先水準,同意其通過科技成果鑒定。
微波通信以其通信效率高、容量大、可靠性好、抗災性能強等特點,成為現代社會以及國防安全領域的重要通信方式之一。微帶隔離器在微波通訊系統中主要起到分離信號、隔離信號和減少噪音干擾的作用,是其中的關鍵元器件之一。
但是,在現有技術中,微帶隔離器基板採用鐵氧體材料,以鉻或鎳鉻做為金屬化過渡層,存在後工序去鉻或去鎳鉻流程較長的問題;鐵氧體材料的脆性大導致通孔加工時孔口崩邊及孔型差影響信號傳輸等問題。
博敏電子介紹,在其“高頻寬微帶隔離器基板關鍵技術及產品”專案中,公司通過濺射特定比例的鎳鉻鐵合金膜層代替常規的濺射鉻/鎳鉻打底、優化蝕刻流程等,解決了關鍵技術難點鐵氧體基板的附著力問題;採用多次鑽孔的方式,解決鐵氧體材料脆性大導致通孔加工時的孔口崩邊及孔型差影響信號傳輸等問題,實現了工藝流程簡化、操作便捷效率高等效果。
鑒定專家評審委員會認為,博敏電子所做的技術研究成果具有先進性、新穎性,項目具有國內領先水準,同意通過科技成果鑒定。
博敏電子執行總經理王強介紹,此次成果鑒定專案是公司繼在印製電路板領域掌握高頻高速高多層、特種材料埋嵌技術、超長超大等特種電路板關鍵技術後的又一大突破,是公司從傳統印製電路板邁向薄膜陶瓷基板、微芯器件等領域的標誌,打開了公司微電子加工業務的新局面。(中國證券網)
