1. 應(yīng)用領(lǐng)域：適用于基站、RFID和其他天線設(shè)計。
2. 材料特性：
結(jié)合低損耗電介質(zhì)與薄型銅箔，減少無源互調(diào)(PIM)和插入損耗。
采用中空微球填料的熱固性樹脂系統(tǒng)，實現(xiàn)低重量和輕密度，比玻璃纖維PTFE材料輕約30%。
介電常數(shù)為3.0，提供成本效益高的解決方案。
3. 性能參數(shù)：
低Z軸熱膨脹系數(shù)(CTE約為40 PPM/oC)
介電常數(shù)溫度系數(shù)約為23 PPM/oC
高玻璃化轉(zhuǎn)變溫度(Tg)超過280oC，兼容無鉛和自動化裝配。
4. 制造兼容性：
符合RoHS標準。
與標準PCB制造技術(shù)和電鍍通孔(PTH)工藝兼容。
專有的無鹵素層壓板設(shè)計，支持更長的鉆具壽命，降低制造成本。
