Adhesives specialist Intertronics has launched the Vermes Microdispensing System (MDS) 1560, a jetting valve for a viscosities, including solder pastes.
The product is based on Dynamic Shockwave Technology (DST), a pneumatic actuator technology, which optimises the valve’s yield to achieve more precise dispensing.
It offers a clock frequency of ~500 Hz and dispenses shot sizes down to ~1 nl, a combination aimed to allow extensive capability in material application, including dots and beads over complex geometries. The system is made up of two parts, the MDV 1560 Jetting Valve and the MDC 1500 Valve Controller.
The MDS 1560 Jetting Valve can be mounted from any of three sides and has a rotatable fluid box. The bayonet-style fluid box is removable, and the tappet change requires no additional tools. It includes an integrated temperature system, including nozzle heating and monitoring.
Peter Swanson, managing director of Intertronics, said: “Because this valve is based on DST, it differs from the traditional, piezo-based products on the market. Optimised channel guidance and configuration of the compression geometries generate a shock wave in the actuator. This is converted into a highly dynamic linear movement due to the special piston area. DST therefore enables a high level of power and precision.
“We have used the MDS 1560 to successfully jet solder pastes of Type 5 and smaller solder particle sizes, without plugging and clogging at the tappet tip ― something which is difficult to achieve with other technology. The valve is cost-effective and easy to use and we will be recommending it to customers for a wide range of applications, particularly for highly viscous and difficult to dispense materials.”
The scope for MDS 1560 application includes electronics, medical device manufacturing, automotive technology and consumer goods.
