New Electronics Assembly Products
December 31, 1969 |Estimated reading time: 5 minutes
New products coming into the supply chain range from flexible test platforms to surface mount connectors, selective soldering systems, conductive epoxies, pick-and-place vision systems, and strain gauge simulation. Suppliers include CheckSum, Bliss Industries, CeTaQ, Zierick, Conductive Compounds, RPS Automation, Pickering Interfaces, Epson Toyocom, and APS Novastar.
SAW OscillatorsLow-phase-noise and low-jitter, the single-output EG-9000GC and the voltage-controlled EV-9000GB SAW oscillators output GHz band (800 MHz ? 2.5 GHz) frequencies at the fundamental. Commercial development is scheduled for completion in the first half of 2009, including a built-in NS-34R crystal-oscillating element. The NS-34R boasts a high Q value, low insertion loss, high power durability, and good frequency-temperature coefficient. The EG-9000GC and EV-9000GB are designed for performance gains in applications that require high frequencies and a highly stable clock, such as communications and measurement applications. They also boast a low-power design (3V and 35mA). Current consumption is 38 mA max. Epson Toyocom Corporation's U.S.-based Timing Products Division, www.eea.epson.com.
Test SystemThe Analyst ems 12KN system offers in-circuit test (ICT) for up to 5,200 nodes, in-system flash programming of serial and embedded flash devices, functional test with standard dual-level probing, and boundary scan. It can be configured to perform all of the tests, or any combination appropriate to the application. Flash programming takes place on up to 384 devices simultaneously with custom data input possible. Non-custom functional test fixtures can be used for combined ICT and functional test. TestJet technology is available on the system. CheckSum LLC, www.checksum.com.
ESD PreventionDue to 3M's recent acquisition of Static Control Components Products Inc., Bliss Industries expanded its line of ESD products from Static Control Components through 3M's other lines. Bliss also offers full ESD engineering support. Bliss Industries Inc., www.blissindustries.com.
Leaded Device AnalysisCapability measurement analysis of leaded devices is enabled on placement systems with the CmController. Machine capability analysis, or MCA test, is a statistical evaluation that represents the highest placement performance in the best conditions. Parameters calculated include component size (X/Y), side overhang, toe overhang, pitch, bent leads, offsets (X/Y), and theta rotation. In addition to standard QFP style devices, other custom leaded devices can also be measured with the CmController. Results can be correlated with quality standards like IPC (IPC-610-C) and can be used to control the component quality coming from different suppliers. If the component is symmetric, the system's vision software is able to detect the edges or pins. By validating machine accuracy using live components, the equipment's user minimizes placement errors and increases quality of the manufactured products. CeTaQ, www.cetaq.com.
The Torsion IDCSurface Mount ConnectorTorsion insulation displacement connectors (IDC) 1245 is designed to withstand shock, vibration, and a broad temperature range. The miniature connectors feature a low profile and a small footprint on the circuit board. They quickly terminate many sizes of wires on PCBs reliably. They boast low initial contact resistance, and resistance gets lower with time in demanding applications. Zierick Manufacturing Corp., www.zierick.com.
Silver-filled Conductive AdhesiveEP-600 silver-filled electrically conductive two-part epoxy adhesive suits component mounting applications using dot dispense or screen printing processes. It can attach resistors, LEDs, grounding wires, etc., to metal and plastic substrates where solder or other conductive epoxies requiring high-temperature curing cannot be used. It enables fast throughput manufacturing of PTF circuits built on temperature sensitive substrates, such as PET, and for snap curing at low temperatures. It cures from 20° to 140°C with cure times from 48 hours to 26 minutes. Snap cure times are possible at higher temperatures. It will continue to cure at room temperature after removal from an oven. Sheer and lateral strength tests show that EP-600 epoxy joints on print-treated PET substrates demonstrate 30 to 40% greater bond strength than other conductive epoxies. EP-600 epoxy's elasticity also allows for differences in thermal expansion properties of the bonded components and for flexing and bending substrates without fracturing surface mount joints. Non-stringing characteristics exhibit quick break-off after dispensing to avoid shorts. Conductive Compounds Inc. (CCI), www.conductivecompounds.com.
Automated Vision Control for Pick-and-PlaceAutomatic vision control is available for the L-Series pick-and-place systems. Vision Control advances precise, fast, and reliable placement of 0201s along with on-the-fly, bottom-up vision placement of microBGAs and ultra-fine-pitch QFPs. The upgrade comprises Cognex machine vision along with 2-µm resolution scales and a user-friendly software application. APS Novastar LLC, apsgold.com.
Strain Gauge SimulatorThe 40-265 strain gauge simulator in PXI provides six channels of strain gauge simulation with high simulation accuracy and performance. Each channel provides a full bridge circuit with resistance control of better than 2 mΩ in one bridge arm, allowing the 40-265 to emulate the operation of a strain gauge bridge circuit. The bridge can be excited by a fixed internal supply or by independent external bridge voltage sources, permitting direct connection to strain gauge measuring systems. The 40-265 is controlled by simple resistance calls to the variable bridge resistor, and each channel has a stored resistance value at which the bridge is balanced. Users can set the bridge to the balance point and then offset the bridge using the resistance control provided by the 40-265 to simulate applied strain. The bridge output voltage is provided directly to the user connector. The 40-265 permits the user to simulate an open connection for fault simulation. A calibration port provides a simple way of using a DMM to monitor the channels and to support in-house calibration of the strain gauge simulator with an external DMM. The module can be used in PXI or in LXI systems with a modular LXI chassis. Pickering Interfaces, www.pickeringtest.com.
Selective SolderingRhythm EX selective soldering system offers a native selective soldering range of 24 × 24" with no manual rotation or adjustment required. It features closed-loop servo-driven X/Y/Z axis motion that articulates the solder wave and flux beneath the PCB. The EX is designed to operate in high mix and high volumes. All systems include independently heated and programmable nitrogen inertion and quick-change solder nozzles. Keep-away is less than 1.5 mm and lead protrusion clearance is 6 mm. Advanced automation capabilities control wave height management, system standby and start-up, automated conveyor width adjustment, dedicated witness vision systems, adjustable temp N2 DirectHeat and ergonomically improved EasyLoad solder pot management. The available fiducial correction vision system can perform solder defect inspection. The EasyLoad feature enables solder pot removal with less effort. RPS Automation LLC, www.rpsautomation.com.
