SKF profile rail guides reportedly provide precise positioning, smooth operation, high load-carrying capacity, high stiffness and unlimited stroke for linear motion applications in the semiconductor, electronics and medical industries.
Feature four precision-ground raceways and a slide unit with four ball circulation paths. The square configuration of raceways results in a guidance system with good rigidity able to accommodate equal load capacity in all directions. Incorporate a two-point contact of rolling elements with the raceways promoting high-speed operation, quiet running and low friction.
Includes high-performance, heavy duty, compact, medium and miniature series. Each is available with various slide configurations (normal, wide, long) and lengths. Different carriage designs can meet particular load and stiffness demands (long carriages promote higher load-carrying capacity and wide carriages promote higher moment stiffness). Guides with specific preload can be supplied.

Model 2600-035 Tip-Seal valve for precision dispensing of medium- to high-viscosity adhesive and sealant materials opens and closes the material passage at the tip of the nozzle to precisely start and stop material flow, and prevent oozing and dripping. Combined with positive-displacement meters delivers precise shot volumes and exact bead profiles.
Use with materials that air dry or cure, such as silicones or polyurethanes. Sealing at the valve's tip prevents material from hardening in the nozzle. Can be used in high-speed stitching or repetitive on-off applications where short segments of material are deposited onto a surface.Material is delivered to the valve by a metering assembly or under regulated pressure from supply tanks or pumps. The dispense rate can be altered during the dispense process to provide a variety of bead-profile sizes and material-flow rates.

Adjustable Flex Feeder 32-136 extends handlse component tapes up to 136 mm wide. Can also handle very deep and long tape pockets.
No tools are required to adjust the width. To adjust the length of the tape pocket opening, simply move the pitch bar backwards or forwards.
Standard configuration allows for up to 10-mm deep tape pockets, but can easily be modified to handle up to 22-mm deep tape.
Delivered with two sets of shafts -- long or short -- so that other feeders can be fitted to the magazine at the same time.

Teradyne Inc. Connection Systems Division (TCS) has launched the Aptera connector platform, a low-profile solution for server, storage and networking applications.
The low-profile design addresses packaging challenges by balancing high-speed interconnect with the need to conserve board space and maximize airflow. The connector's 10 mm (.39") slot pitch offers flexibility for applications that need high-performance connectors in tight spaces. Electrical test results reportedly demonstrate excellent transmission characteristics and cross talk under 2% at a 50 pico sec. rise time (20-80%). Combined with a matched impedance interface and zero skew, is scalable for future system design requirements.
Designers can choose appropriate connection types and the amount of signals. Features a straddle mount design with solder leads for the daughtercard and press fit for the backplane.
With dedicated power delivery and sequencing on the card edge, the Aptera connector provides the superior reliability and convenience of a backplane connector system.
Offers the following components: high-speed differential, single-ended, power and an L-Series version for low-peed data lines.

FRANKLIN, MA, Jan. 20 - Speedline Technologies, Asia, will highlight Camalot dispensing, Electrovert reflow soldering and MPM stencil printing systems at its booth (3305) during SEMICON China in Shanghai in March.
Camalot XyflexPro HVB dispenser uses a proprietary, patent-pending, conveyorless material handling system and dual dispense heads. Typical performance is three to five times faster than conventional single lane systems. Features DU (dispense unit) pump technology, with positive shut-off auger technology and a continuous flow multi-piston pump with increase flow rates and improved repeatability.Available on Electrovert OmniExcel Pb-free capable reflow ovens, the self-cleaning Electrovert Flux Extraction System is said to reduce maintenance intervals and deliver a gain in uptime. Consists of multiple, multi-stage collection units located within the heating sections to continuously scrub process gas for unwanted particulates. Automatically collects flux into easy-to-exchange jars and notifies users when maintenance is required.
Auer Boat print processing is now available on the MPM AccuFlex and the MPM AP Excel systems. Demonstrations will be featured on the AccuFlex stencil printer.
The AccuFlex stencil printer is suited for moderate volume, high-mix printing. Combining accuracy and flexibility in a compact footprint, the printer offers a range of expansion options. Designed for production of about 8,000 boards per week, with two or more product changeovers per shift.The AP Excel printer's throughput, uptime and functionality are reportedly ideal for demanding, high-volume printing applications. Standard minimum base cycle time is 6 sec. using MPM's SpeedMax high-speed package.
The latest High-Power Target is a transmission target consisting of an interaction layer made of tungsten and a special backing layer that provides improved heat transfer and lower focal spot temperature.
Its construction allows users to operate the x-ray tube with higher energies at the highest possible resolution, allowing for increased image contrast. Ideal for inspecting objects with low-contrast structures, or with high absorption structures.
As a rule, the thermal stress applied to the target increases with decreasing focal spot size and increasing tube power. Focal spot size, however, is a critical factor in determining geometric magnification and image resolution, while tube power influences the x-ray intensity output.

Ultra-efficient, low-cost RF power amplifiers enable the manufacture of high-performance, low-cost RF power amplifiers in common silicon semiconductors. Architecture enables models of power amplifiers that inherently perform the function of traditional RF transmitters and eliminate traditional transmitter hardware.
Are monolithic (single chip) implementations that can be produced in less expensive, high-volume silicon semiconductor processes. Offered in two families- the vector power amplifier (VPA) and digital power amplifier (DPA). Both reduce transmitter power consumption for many battery-powered wireless products by 50 to 80%.Currently for applications up to 3GHz RF frequencies.

The 752 series compact, low-maintenance dispense valve reportedly applies accurate, consistent amounts of cyanoacrylate adhesives and other assembly fluids on automated production lines.
Pneumatically operated valve has no tubing to leak or O-rings to wear out. Precision diaphragm rated for tens of millions of cycles provides long, trouble-free operation. A fast, clean cutoff after each shot eliminates dripping, waste and cosmetic damage to parts.
The amount of cyanoacrylate dispensed is determined by fluid pressure, flow rate and valve open time. Adjustable stroke control allows the flow rate to be fine-tuned, while valve open time is regulated with a microprocessor-based controller. Valve open time can be adjusted in increments as small as 0.001 sec.
Ideal for automated assembly machines, XYZ tables and retrofits on current production lines.
