Welcome to TECHNIQ VIET NAM
BERGQUIST BOND PLY TBP 850 (also known as BERGQUIST BOND-PLY 100) is a thermally conductive, fiberglass-reinforced, pressure-sensitive adhesive tape. It provides high bond strength and is designed to efficiently transfer heat while offering easy application due to its double-sided adhesive nature.
✔ Key Features & Benefits:
✅ Mounting heat sinks onto BGA graphic processors and drive processors
✅ Mounting heat spreaders onto power converter PCBs or motor control PCBs
