Asymtek's New Slider Valve 20% Faster
Faster dispense valve. .
Carlsbad, CA — Asymtek, a Nordson company, is introducing the new SV-100 Slider Valve for solder paste dispensing. Up to 20 percent faster than standard auger dispensers, the new valve achieves 20,000 dots per hour (on 1mm grid) while delivering accurate and repeatable dots of less than 300µ (12 mil) for solder paste types 4, 5, and 6. Dots as small as 125µ (5 mil) in diameter can be achieved with type 6 paste.

The slider valve can be used to selectively dispense into small and hard-to-reach places where it is difficult to screen print. It dispenses dots and lines of pastes and fluids that contain metal additives with minimal clogging, which can be a problem with traditional needle dispensing.

The new valve is compatible with lead-free and no-clean solder pastes as well as silver-filled epoxies. Standard solder pastes (types 4, 5 and 6) can be used to achieve excellent results, saving costs. The SV-100 is fast and accurate for a range of production requirements including solder paste dots for passive components smaller than 0603, rework of BGA and QFN electrical connections, lines and patterns for RF shield attach, low volume/high mix applications, and unique patterns of conductive epoxy.

Slider valve technology utilizes high-frequency, piezoelectric-drive actuation to quickly deposit small dots of thick fluids. Lever action aligns valve seats to open a smooth path for fluid flow. Within milliseconds, the holes are forced out of alignment to stop fluid flow and a dot is formed. It is designed for use with the company's DispenseMate, Spectrum 8xx and Axiom dispensing systems.
