TS7000 Interchangeable Material Path Series Rotary valve is based on the technology of TS5000 Series Rotary Microvalve. Is designed with no dead fluid volume, field replaceable feed screw/cartridge assembly; is interchangeable with TS5000DMP feed screw auger inserts, has a flexible motor, syringe, and a needle mounting option. Is available in three feed screw auger sizes (16-pitch, 8-pitch and high output 8-pitch), all made of hardened steel. Encoder motor version is available for applications that require closed-loop motor control with encoder feedback. Reportedly provides repeatable dispensing of medium- to high-viscosity fluids and pastes. Applications include small-dot dispensing of dispensable-grade solder pastes, silver epoxies, surface mount adhesives, dispensing beads of structural adhesives, cavity and cam filling, and glob top dispensing.

mySelective 6748 selective soldering machine now has PCB warpage compensation. Is said to ensure points to be soldered are always the same height above the wave, even if board has slight warpage. A noncontact laser sensor measures the distance between an assembly in process and the wave prior to soldering. Measures the distance of several target positions on the bottom side of the assembly, while the board is held in the gripper (robot product handling device). Chooses a reference point (near the corner of the board) and a measurement point (near the middle of the board), and others if needed, so the sensor can take measurements and teach itself the board shape and degree of distortion. It then makes appropriate calculations (Z offset).

The ASD-700 PCB DeStacker has an enhanced top-loading exterior. Is said to provide a small footprint for loading PCBs at the front of the line. Is capable of holding up to 80 PCBs ranging in size from 2 x 3" to 18 x 20". A floating center support mechanism rises upward and is used to prevent larger PCBs from flexing during the lowering process onto the edge belts. Load and pass mode functions are standard. Touch panel optional.

The updated Cartridge Product Guide features dispense nozzles, pistons, end caps, tip caps and cartridge adaptors. Includes a complete cartridge component breakdown, including: Disposable, plastic cartridges provide an efficient method to meet all types of production requirements. Plungers with a front wiper edge clean each cartridge thoroughly. Tip caps and end caps are available, making the system reportedly ideal for pre-packaged materials such as pre-mixed and frozen. End caps are used to prevent dust contamination when the cartridge is not in use. Pistons are used to ensure even pressure distribution throughout the fluid while dispensing. Cartridges are used when a standard syringe capacity is not big enough, and tip caps are used to seal cartridges when not in use. Also included in the guide is the TS Series aluminum retainers, which twist-lock to their dispensing cap. Retainers are lightweight and permits up to 100 psi applied air pressure. Also includes TS retainer caps, G-Series retainers and G-Series retainer caps.

The latest product guide includes dispensers, 700 Series consumables, and dispensing tip options. Entry-level dispensers include the TS250 digital dispenser, for general dispensing applications, and the TS255 digital dispenser, for precision dispensing of low-viscosity fluids. Also features advanced digital dispensers: the TS350 and TS355. The TS350 is capable of dispensing a range of fluid viscosities, while the TS355 specializes in precision dispensing of low-viscosity fluids. Featured 700 Series consumables include the receiver head assembly, end caps, air powered pistons, syringes, syringe assembly kits, and tip caps double helix thread. Dispensing tip options include the TE Series Tips, TE Series Bent Tips, TT Tips, TS-P Plastic Tips, and Brush Tips. The dispensing systems can be accessorized with a finger switch assembly, syringe holders, a vacuum pencil and control unit, a manual syringe gun, a dispensing tip kit, and a foot valve dispenser. Applications include heat sink compound, surface mount adhesive, grease, solder paste, flux, silicon, anaerobic, and needle color-coding.

This system validates barcode labels as they are dispensed. Each label’s barcode is scanned and recorded in a database. Is automatically advanced and peeled from its liner and ready to be applied. Applications include validation that each number on the roll of labels has been dispensed for ISO requirements and use for inventory management when the database is used in conjunction with ERP systems. Optional PC-based validation software available.
