Dispensers for paste solder and adhesive dosage Print E-mail

Liquid Media Dispenser and Vacuum Pipette DP-02

This two-in-one microprocessor-controlled device combines a dispenser and vacuum pipette for use in surface mount board assembly (SMT) or whenever you have a requirement for the handling of delicate components and the application of an accurate dosage of a liquid or paste-like media.


The dispensers design enables the application and dosage of glues (adhesives), solder pastes, resins and other liquids . It is based around a system of pressure impacts, the length of which is carefully defined. Pulse length is adjustable, derived from a crystal oscillator. A built-in timer enables single doses to be repeated or it can be put to disabled mode. All settings can be stored in a memory which is independent and not powered up from the mains. Settings for up to four types of components can be stored simultaneously.

The vacuum pipette was designed for hassle-free pick-up and placement of delicate components. Automated vacuum control makes it possible for a component to be "picked " as it comes into contact with the pipette and during next step "placed" as it comes into contact with board (for all the various modes of operation see below).
