Wirewound Chip Inductors
The DR354-1-2-3-4 series surface mount wirewound chip inductors protect against electromagnetic interference (EMI) for small devices in high-frequency filtering applications. Available in a range of inductance values, the series features a compact chip design with a low-seated profile of 1.02 mm above the board. The small footprint makes the inductors suitable for automotive applications, consumer electronics, handheld scanners, instrumentation, cell phones, and personal digital assistants (PDAs). Datatronic Distribution, Inc., Romoland, Calif., www.datatronics.com.
Machine Vision Camera
The XCI-SX1 monochrome Smart Camera for machine vision features a ½-type progressive-scan, charge-coupled device (CCD) with square pixels said to produce high-quality SXGA (1280 × 1024) images at 15 frames per second (fps), or 34 ps. The module is equipped with an embedded CPU, and a 10Base-T/100Base-TX interface for network connectivity. The camera includes an on-board, Linux-based operating system (OS), and also runs Windows XPe. This gives OEMs and system integrators the ability to install various semantic web (SW) applications and third-party vision libraries, or develop and apply customized applications. Captured images are processed within the camera, and the data transmits directly to a PC over a network. XCI-SX1 targets machine vision applications such as object recognition, inspection, measurement, and alignment. Sony Electronics Inc., Park Ridge, N.J., www.sony.com/videocameras.
Solder Recovery System
The EVS Series solder recovery systems, including the EVS 3000 and EVS 6000 systems, enable 20- and 44-lb. capacities, respectively, for single-operation de-drossing of large wave soldering machines. Both systems are equipped with a large integrated hopper said to speed de-drossing times by up to 50%. Hot dross is loaded into the hopper and sealed into the machine. The process then recovers the solder into a tray in ingot form, and places them into the solder pot. Spent dross moves through a chute to a covered dross bin. A standalone, four-part filtration system extracts air, while a hopper-extraction system prevents the escape of fumes and dust created during loading. An automatic air-knife cools the molten solder ingots. EVS International, Isle of Wight, U.K., www.solderrecovery.com.
Pick-and-Place System
The FLX2020-V flexible pick-and-place system for high-mix production has a capacity of up to 310 feeders, and features graphical control software, inventory control and traceability, and quick changeover times. The system can also be extended to the FLX2030, featuring 470 feeders with placement of up to 15,000 components per hour (cph). Using the EASYPLACER software, complex coordinate lists are converted into a virtual view of the PCB. The FLX2020 system accepts nearly all feeding systems, allowing an independent unit to be used as a feeder, such as a vibratory bowl feeder for bulk components with no electrical connection to the machine. Feeder flexibility is said to enable customer-specific applications. The system is also equipped with laser- and vision-alignment systems - providing chip shooting and ultra-fine-pitch placement. A management information system (MIS) is also included for production optimization. ESSEMTEC, Aesch, Switzerland, www.essemtec.com.
ASSEMBLY TOOLS & EQUIPMENT
PCB Clamping System
The Quik-Lok PCB clamping system for MPM UP2000 and AP25~27 series printers eliminates the need for vacuum-chamber board fixtures found on most MPM printers. The clamping system can be retrofitted in the field in about one hour, and is said to provide secure, over-the-top-type PCB clamping, as well as tool-less, hands-free changeovers. Ovation Products, Bethlehem, Pa., www.grid-lok.com.
CLEANING MATERIALS & EQUIPMENT
Solder Paste and Flux Remover
AquaSonic AQP Solder Paste and Flux Remover is a non-hazardous, non-flammable, and odor-free solution for cleaning stencils, PCBs, tools, and other surfaces. The remover, which was certified by the South Coast Air Quality Management District (SCAQMD) as a Clean Air Solvent, works in ultrasonic cleaning machines, and is available in concentrate form, or pre-mixed with water. Using a proprietary electro-chemistry technology to clean, AQP reverses the normal polarity of the contaminant, causing “like” contaminant and substrate charges to repel each other, preventing reattachment to the substrate. The 90% water-based solution was formulated to remove no-clean and lead-free solder pastes, SMT epoxies, and flux residues. JNJ Industries, Franklin, Mass., www.jnj-industries.com.
DISPENSING EQUIPMENT
Dispensing Workstation System
The Ultra 2400 workstation dispensing system is said to apply consistent amounts of adhesives, lubricants, silicones, epoxies, and other fluids in the bench-top assembly process - from beads to dot diameters of 0.004". Featuring a vertical design to conserve space, the workstation is reportedly 60% smaller than electro-pneumatic dispensers. The dispenser is capable of 0-100 psi for all fluids with a rate of more than 600 cycles per minute. Specifications include a multi-function, multi-language display with simultaneous air pressure, time, and vacuum-pullback readouts. A high-speed solenoid enables accurate deposits, while an air-management system provides rapid response and stabilizes cycle-to-cycle control. EFD, Inc., East Providence, R.I., www.efd-inc.com.
INSPECTION EQUIPMENT
Video Inspection Microscope
The Optilia Flexia BGA/SMT video inspection microscope visually inspects solder joints on PCB components, solder/flux mixtures, bare circuit cards/pads, cables/connectors, wire bonds, and stencils. Imaging applications include digital-image capture, video recording, and optical measurements. The microscope incorporates a 1-60× look-down, macro-zoom lens, as well as a 4× zoom look-under, side-viewing lens to inspect 12-mm-deep BGAs, microBGAs, chip-scale packages (CSPs), and flip-chip packages with ~0.05-mm standoff. Optional software measures bump height, radius, and wetting angles, while the database and reporting environment develop case examples for inspection-verification reference, training materials, and other documentation requirements. FocalSpot, Inc., San Diego, Calif., www.focalspot.com.
Intelligent Camera
The IMPACT A-10 intelligent camera delivers advanced inspection capabilities in a vision-sensor profile. The camera is equipped with the IMPACT Software Suite, which reportedly enables fast setup, storage, and viewing of captured images. The compact camera includes a high-performance microprocessor, real-time operating system (RTOS), and a digital-imaging sensor. The electronic components are contained in a sealed industrial unit that can be installed directly into assembly lines. Because of its range of discrete, serial, and Ethernet I/O, the camera is also compatible with a broad scope of industrial control equipment and instrumentation. PPT VISION, Inc., Eden Prairie, Minn., www.pptvision.com.
TEST EQUIPMENT
In-circuit Test Extension
Medalist iVTEP (intelligent Vectorless Test Extended Performance) is less-dependent on leadframe geometries, reportedly yielding more reliable measurements for challenging PCB device packages. An extended version of proprietary VTEP technology, iVTEP suits small-geometry packages, flip chips, devices with minimal or no leadframes, and devices under heat spreaders. iVTEP can be used with existing VTEP hardware, and is available on the Medalist i5000 and 3070 in-circuit test (ICT) platforms.
