Otterfing, Germany — VERMES Microdispensing has launched its modular, highly flexible 3280 microdispensing system. The system is designed to adapt to various media and has many advanced fea- tures. Contact-free, precise media allocation enables fast cycle times. The fluidic parts uncoupled from the system’s valve drive reduces maintenance costs. The system is designed to dispense the small- est, identical droplets at the highest possible speed. The jet dispensing system uses a piezoelec- tric actuator. To further enhance its extremely fine dispensing, especially for high-viscosity media, the company has expanded its MDS 3000 series with the MDS 3280 all-around system.
The MDS 3280 has a new valve design that is suitable for a wide range of materials, including SMT adhesives, silver conductive adhesives, LED phosphors, and underfills, as well as silicones, con- ductive glue or solder pastes and hot melts. The system is able to dispense droplets less than 6 mil (150 μm) in diameter with consistency

and repeatability. The MDV 3280 valve is equipped with a “top adjust” setting that allows quick and comfortable configuration and free pair- ing of nozzle insert and tappet.
Parameter settings can be quickly and easily

changed during operation. This allows the system to rapidly adjust to changing conditions, such as varia- tions in material viscosity, modifications of dispens- ing patterns and the application of different dispens- ing quantities. The connector technology of the flu- idic part that is separate from the actual valve body, what VERMES calls its “bayonet fluid box body,” is designed to ensure flexible coupling and enables easy handling and cleaning, since it can be removed quickly.

The desired dispensing direction of the valve can also be changed easily. This enables fast and seamless integration into previously inaccessible or confined spaces. The tappet can be changed while the valve is in operating position, avoiding difficult part replacement and critical service downtime. The nozzle heater is integrated into the body of the fluidic part and keeps it at the correct temperature without taking up much space. Due to the continuous temperature control and the con- trol of the material pressure, the dispensing quali- ty remains constant until the car- tridge has been emptied. Contact: VERMES

Emil Otto Develops Activator System for Fluxes
Eltville, Germany — Flux gels are often used for rework on populated PCBs. In the past, fluxes for manual and repair soldering, which included other activators that were used for series production, often had to be used. Emil Otto’s newly developed flux gels are based on uniform activa- tors, which are contained in the pre- vious electronic fluxes.
The company offers correspon- ding gels with identical activators for fluxes EO-B-001A to C, EO-B-002A to C, EO-B-006A to C, EO-B-007A to C, and EO-B-009A to C. The respec-
EO-B-002 flux gel containing uniform activator.
tive gel is highly concentrated and exhibits high activation, as well as good wetting and spreading. The gel is applied from a dosing syringe with a metal dosing needle, allowing accurate application and positioning of the flux.
Being able to use flux for mass production and small series, without needing to pay attention to the activa- tor has many advantages. Employees cannot confuse different fluxes, cross- reactions are absent when using dif- ferent activators, and the customer can obtain all flux products from a single source.
