Nordson EFD Introduces New xQR41 MicroDot Needle Valve


Reading time ( words)

Nordson EFD, a Nordson company, the world’s leading precision fluid dispensing systems manufacturer, introduces the xQR41 Series MicroDot needle valve. The valve features a 60% smaller form factor than standard valves, an exchangeable modular design for greater customization and process control, and a Quick Release (QR) clasp that allows easy removal of the fluid body to replace wetted parts in seconds. The new valve expands manufacturing opportunities for multiple applications and industries, especially those related to wireless devices, sensors, mobile phones, and other high-end electronics.

The xQR41 valve’s small profile of 66 mm length x 23.7 mm diameter (2.60" x 0.93") enables multiple valves to be mounted closer together for greater output per batch, increasing production throughput. Ideal for automated assembly processes, the needle valve can dispense in tighter spaces and at more complex angles. Weighing only 141.4 g (5.0 oz), the xQR41 valve reduces the tooling payload. This not only means faster actuator arm movement and improved positioning stability, but also reduced tabletop automation (TTA) motor and belt wear. The xQR41’s small form factor also results in a smaller wetted path, resulting in less retained fluid volume, which minimizes fluid waste. It can be fed from a variety of reservoirs, syringe barrels, external cartridges, or tanks.

The valve's unique QR clasp secures the fluid body to the air actuator and can be removed with a turn of a thumbscrew – no tools required. No longer is it necessary to remove the entire actuator or valve assembly from mounting fixtures. Full change-outs take seconds, not minutes. This is especially important in applications with fluids that have a curing time where the wetted part must be removed as quickly as possible and returned to operation.

The pneumatically-operated, adjustable valve applies precise micro-deposits as small as 150 µm (0.15 mm) (0.006”) of low- to high-viscosity fluids onto a substrate. The xQR41’s exchangeable modular design can be configured with stroke adjustable or non-adjustable cap, BackPack™ valve actuator, low-profile mounting block, and 90° air and fluid inlet fittings. The fluid body can be aligned and locked at 360° intervals to accommodate mounting, positioning, and fluid inlet alignment needs. It can be installed on many automation platforms.

“With rapid interchangeability, a smaller form factor, and infinite configurability, Nordson EFD’s new xQR41 MicroDot needle valve not only offers new possibilities for fluid dispensing, but it also saves time and costs and increases productivity,” said Claude Bergeron, product manager, Nordson EFD.

Book Excerpt: 'The Printed Circuit Assembler’s Guide to… Solder Defects'

06/07/2022 | I-Connect007 Editorial Team
Solder defects in surface-mount technology (SMT) assembly have been an issue for decades. Further, the combined challenges of Pb-free soldering and ever-increasing miniaturization have resulted in new or exacerbated defects in electronics assembly, but there are proven ways to avoid defects. This book will be especially beneficial to PCB assemblers in improving their assembly processes and the reliability of the end-product, eliminating field failures, and reducing costs.

How to Minimize Quoting Time and Increase Accuracy in EMS Production

03/30/2022 | Mark Laing, Siemens Digital Industries Software
New product introductions (NPIs) and customization have been increasing rapidly over the past few years—with the results that the already-small profit margins in electronics assembly are shrinking even further. Fifteen years ago, the PCB was the product. Today, most products are a system, with multiple PCBs, cables, and enclosures. Many manufacturers want to provide turn-key products that have multiple BOMs, making the assembly process even more complicated.
