C-EP4647 Technical Data Sheet Single component epoxy adhesive單組分環(huán)氧樹脂粘接劑
PRODUCT DESCRIPTION 產品介紹
C-EP 4647 is a one component, low viscosity, reworkable CSP/BGA underfill. The material cures at low temperature. The cured material shows excellent protection for a variety of mechanical stress, including shock, drop and vibration etc.
C-EP 4647是一種單組分,低粘度,可返修的CSP/BGA底部填充膠。該材料可低溫固化。在固化后該材料可對手提設備中的焊接部在承受沖擊、落下、震動等機械和熱應力時提供優(yōu)異的保護。
