High viscosity KSV1000A-T Concentric Screw Valve for smart
manufacturing
The concentric screw valve is an advanced dispensing solution ideal for high-precision
applications in the semiconductor industry. It uses a motor-driven
screw to deliver continuous and pulse-free flow of high-viscosity
materials such as underfill, epoxy, and thermal interface materials (TIMs). Its concentric design ensures stable and repeatable dispensing,
making it suitable for die attach, SiP module bonding, and
microelectronic encapsulation. The valve supports both continuous
bead dispensing and precision dotting, with clean cut-off and
minimal material waste. It integrates easily with automated lines,
helping meet strict reliability and yield requirements in advanced
packaging processes.
Core Advantages
◆ With closed-loop servo motor, precise positioning, dispens-ing
repeatability of 98% and minimum dispensing amount of 0.1ul can be
achieved.
◆ With syringe guide installation design, 10/30/50ml syringes can
be used and quickly removed and replaced to facilitate operation.
◆ With special negative pressure controller, the lower viscosity
limit of applicable media can be reduced to 2000cps.
Main appliaction
TIM (Thermal Interface Material)
Application description: Thermal conductive materials such as
thermal grease, thermal gel, thermal pad glue, etc. need to be
filled between high-performance chips and heat sinks.
