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.

Camalot SmartStream non-contact dispense pumps now come with optional Dual Head Synchronous Mode. Synchronous dispense mode said to improve throughput by 50% while eliminating risk of poor yields/scrapped product experienced by alternative approaches to simultaneous dispensing on multi-up circuits. Is capable of detecting panel rotation and will automatically switch to an asynchronous dispense mode to ensure that both heads dispense accurately on the PCBs within the skewed panel. New software algorithms ensure dual pumps are pitched correctly and have identical flow rates. Is compatible with the Camalot XyflexPro+ and FX-D dispense systems and may be retrofitted in the field.

Screens with HT stainless steel mesh are woven on looms. High-tension mesh is capable of achieving tension values higher than traditional meshes. Permits the use of a lower off-contact and less squeegee pressure. Shows improvements in the separation of the ink from the mesh. Ink clears the mesh opening easier.
