Stamped spring pin socket for 0.8mm pitch Infineon LFBGA

A new socket addresses high-performance requirements for burn-in and test applications: the SBT-BGA-6553. The contactor is a stamped spring pin with 31

gram actuation force per ball and cycle life of 125,000 insertions. The self-inductance of the contactor is 0.88 nH, insertion loss of < 1 dB at 15.7 GHz, and capacitance 0.097pF. The current capacity of each contactor is 4 amps at 80C temperature rise. Socket temperature range is -55C to +180C. Socket features a floating guide for precise ball-to-pin alignment. Socket also includes integrated compression plate that has a center opening for accessing device top surface. The specific configuration of the package to be tested in the SBT-BGA-6553 is BGA, 17x17mm body size, 0.8mm pitch, and 20×20 ball array. To use, drop IC into the socket, place the lid, and apply down force using four screws alternatively. This socket can be used for hand test and quick-turn custom burn-in applications with the most stringent requirements. Ironwood Electronics

Voice coil positioning stage

The VCS13-108-LB-01-MCF voice coil positioning stage uses the voice coil motor NCC13-30-108-1SH to generate a continuous/peak force of 10.8 lbs [48.0 N]/32.4 lbs [144 N] with a total stroke length of 1.3 in [31.8 mm]. The

1.0-micron resolution encoder allows for precise positioning. The load cell with signal conditioner (100 N capacity, 1 N resolution) allows for 1-100 N of push/pull force feedback. It comes supplied with a rigid recirculating ball linear bearing. The motor coil is the moving part of the assembly to reduce the moving mass of the system. Power is supplied to the motor via a high flex, high reliability flat ribbon cable. Applications include mirror tilt and focusing, Z axis for pick and place equipment, medical diagnostic probes and beam steering, vision inspection, miniature position control, and clean rooms.

High-speed, direct-drive linear motor with integrated encoder

This vendor has added a new linear motor to its SDLM Series of high-speed, direct-drive linear motors. The SDLM-051-095-01-05 is a powerful, compact

linear actuator measuring 2.00 in. (50.8 mm) in diameter and 3.75 in. (95.3 mm) long. It has a 1.0 in. (25.4 mm) stroke and features a resolution of 5 microns (0.000197 in.). The integral, linear optical quadrature encoder is directly connected to the shaft for the greatest possible bandwidth and accuracy and is protected by the housing. This fully enclosed linear motor features a continuous force rating of 7.6 lbs (33.9 N) and a peak force of 24.1 lbs. (107.2 N) at 10% duty cycle. Applications Include: vibration, noise cancelation, photonics, gimbals, antenna positioning, medical devices, semiconductor handling, SMT machines, assembly, wafer handling, optical focusing, dynamic vibration absorption, scanners, and laser beam steering. The non-commutating SDLM-051-095-01-05 with 5 micron resolution direct-drive linear motor has a quiet, long-life plain linear bearing, nonrotating shaft, predrilled and tapped mounting holes, and threaded (internal) ends of the shaft for easy integration into new and existing applications. These low-cost direct drive actuators or electric cylinders are coupled directly to the load providing high acceleration and high speed with zero cogging and the zero backlashes. They are a low-cost alternative to pneumatic and hydraulic actuators. The SDLM-025-095-01-05 is also available with a complete plug-and-play matching motion controller. Moticont

RF coaxial spring probes for high-frequency test

The CSP-40A-024 and CSP-40G-021 radio high frequency test probes are designed to mate to a variety of industry standard connectors such as MMCX, Fakra, SMB, and U.FL. Made for the PCBA test market, they combine proven RF

performance with ease of use to ensure accurate and reliable testing. The CSP-40 coaxial probes provide an instrumentation-quality interface for broadband RF measurements in excess of 6 GHz, and provide a cost-effective solution for high volume board testing. With the addition of the CSP-40A-024 and CSP-40G-021 high performance radio frequency probes, ECT expands its industry-proven high-speed test interface portfolio. The CSP-40 series offers outstanding signal integrity and is capable of bandwidth measurements in excess of 6 GHz @ -1dB. The CSP-40 probes allow for high frequency functional tests in both high volume testing and engineering lab environments. The probes provide consistent 50 Ohm impedance for repeatable measurements. The CSP-40A-024 and CSP-40G-021 provide spring-loaded compliance for both the center signal probe and outer housing that provides ground contact. The articulated contact allows for correction of targeting errors. The CSP-40 series features a rugged design for inline applications and an easy-to-replace center conductor probe. The adjustable snap ring feature ensures easy and reliable mounting. Everett Charles Technologies

2.5 kV high-voltage module

A brand-new high-voltage module enables users to quickly and easily insert four high-voltage contacts in a space-saving carrier without the use of tools,

which reduces assembly time to the absolute minimum. The use of specially formed MULTILAM contact technology in the CombiTac high-voltage Ø 1.5 mm contacts guarantees long-life connector performance (100,000 mating cycles), and the overall solution is resistant to vibrations and shock. The new CombiTac 2.5 kV high-voltage module is suitable for testing equipment and high-voltage transfer applications in A&D, railway, and general industry. Features include long-life solution—up to 100,000 mating cycle; quick assembly with tool-free insertion of pin and socket contacts; and resistance to shock and vibrations.

Harsh media-compatible pressure transducers

The MP Series of harsh-media-compatible pressure transducers uses proprietary DURAsense unique packaging and microelectromechanical systems (MEMS) pressure sensor integration strategy with a hermetically sealed pressure fitting at a low cost while eliminating the troublesome and highly

unreliable “O-ring” popularly used to seal the sensing element from its measured media. They are suitable for applications including HVAC, heat pumps, compressors, hydraulics, off-road vehicles, and industrial equipment. The MP Series is comprised of a ceramic substrate, on which the MEMS piezo resistive pressure sensor is hermetically attached. The design utilizes a media compatible rear-entry packaging strategy for media contact with the Silicon sensor, thus eliminating the contact of bond wires and electrical signals to the media, which also enhances reliability and the ability to operate in conductive media. This approach significantly enables optimized sensor chip performance at reduced cost and with a high level of reliability. Additionally, this packaging approach provides improved reliability and performance at a lower price over pressure sensors that use an oil-filled cavity and a metallic diaphragm. The pressure sensor ceramic is hermetically bonded to the pressure fitting, which gives the series enhanced ruggedness and reliability and avoids O-ring problems due to incompatible materials. Signal conditioning for the pressure measurement and performance compensation is provided by an Application Specific Integrated Circuit (ASIC) mounted on a PCB.
