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.

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.

MCP screen printer has a head design with variable attack angle printing that reportedly permits constant solder pressure independent of stencil thickness. Single-head system reportedly reduces maintenance by half. Board cycle time is as low as 11 sec. Reduces defect per million figures by up to 50%. Has a flat-metal single-head squeegee. Variable angle print head improves repeatability of paste deposition for 01005 components. Produces solder shapes with stencil thickness down to 50 µm, and half-edging stencils with stencil steps of 30 to 50 µm. Is ideal for PCBs mixing 01005 (0.4 mm x 0.2 mm) types with larger component sizes.
