Multicore DA101 incorporates a no-clean, ROLO flux and is formulated for printing processes. Is said to withstand temperatures of 300°to 330°C for high-Pb reflow profiles and Pb-free temperatures between 240° and 270°C. Wets to copper, NiPdAu and Ag finishes, among others. Exhibits less that 5% void instances on average. Can be cleaned with standard cleaning chemistries.

A thick film dielectric and conductor system improves the mounting of silicon ICs to aluminum substrates. Provides low thermal resistance between the chip and heat sink in applications such as HB LEDs. The glass system of the Pb- and Cd-free dielectric paste was developed to offer thermal conductivity on both 3003- and 6061-grade alloy aluminum substrates. Reduces bowing by closely matching the CTE of aluminum. Also, a Pb-free silver conductor paste, fired together at 550°C with the dielectric paste, provides solderability and adhesion. Is for applications such as direct-mounted LEDs.

Model 340PS and 340PSL positive-displacement dispensing valves for fluid dispensing incorporate the efficiency of a disposable fluid path from the reservoir to the dispense tip. Sequenced piston actuation dispenses a consistent shot-to-shot volume. Are effective with materials that are shear sensitive, extremely high or low in viscosity, possess tacky or stringy characteristics, or have drifting viscosities due to limited pot life. 340PS is suited for shot volumes from 0.004 to 0.180 mL. 340PSL offers shot size capability up to 1.200 mL. Both are available with polyurethane, flexible polyethylene or Teflon tubing.
