Slide Valve dispenses repeatable solder paste dots and lines.

Press Release Summary:

Achieving 20,000 dots/hr on 1 mm grid, SV-100 Slider Valve delivers dots of less than 300 µm for solder paste types 4, 5, and 6 and dots as small as 125 µm in diameter with type 6 paste. Used for dispensing into small and hard to reach places, it is compatible with lead-free and no-clean solder pastes as well as silver-filled epoxies. Valve is suited for solder paste dots for passive components smaller than 0603 and rework of BGA and QFN electrical connections.

Original Press Release:

Asymtek's SV-100 Slider Valve Is up to 20% Faster with Smaller Dots Than Standard Auger Dispensers

Delivers accurate and repeatable solder paste dots and lines

Carlsbad, CA - April 23, 2008 - Asymtek, a Nordson company and leader in dispensing, coating, and jetting technologies, introduces the new SV-100 Slider Valve for solder paste dispensing. Up to 20% faster than standard auger dispensers, the SV-100 achieves 20,000 dots per hour (on 1mm grid) while delivering accurate and repeatable dots of less than 300 microns (12 mil) for solder paste types 4, 5, and 6. Dots as small as 125 microns (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.

The SV-100 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 SV-100 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 Asymtek's DispenseMate, Spectrum 8xx and Axiom dispensing systems.
