AOI SystemVi-5000 AOI system reportedly offers 100 percent inspection of boards up to 457× 508 mm at speeds up to 250,000 cph. The inspection system is said to verify component positioning (X, Y and q), polarity, text and presence/absence; inspects solder paste and joints; and detects bridges. The system's granite Y-axis reportedly is unaffected by changes in factory temperature, allowing accuracy of 5 æm at six sigma. The system also is equipped with a high-quality camera lens with a large field of view that prevents component image distortion. Additionally, improved linear motors and closed-loop optical encoders provide repeatability of 2 æm. ViTechnology LLC, Haverhill, Mass.
IGBTsSMPS II IGBTs are designed to replace 500/600 V MOSFETS in SMPS, PFC and other high-power applications without redesign of the gate drive voltage circuitry. The component's gate drive voltage requirement has been reduced to 8 to 10 V, similar to a MOSFET, allowing larger die size power MOSFETs or multiple MOSFETs in parallel to be replaced with a single SMPS II IGBT. The IGBT technology is said to improve power density, system efficiency and reliability, and enable operation to 150 kHz without current de-rating. Conduction losses are said to be lower, especially at high temperatures, and gate charge is reduced by percent. Fairchild Semiconductor International, San Jose, Calif.
Stencil PrinterMPM AccuFlex stencil printer is targeted for use by manufacturers producing approximately 8,000 boards per week, with two or more product changeovers per shift. The printer reportedly handles boards from 3× 2" to 23× 20", and is capable of printing 0.012" pitch devices with consistent accuracy. A "high-performance" option is said to reduce the printer's cycle time by as much as 5 seconds, and a triple-track conveyor system with 3 mm bottom-side edge clearance facilitates both board flow and integration flexibility. Several other options, such as automatic board support pin placement and programmable stencil positioning, are said to reduce or eliminate operator intervention during changeovers. Speedline Technologies Inc., Franklin, Mass.
Conductive Adhesives/Potting CompoundsSyon electrically conductive adhesives/potting compounds reportedly can be used to form conductive paths in applications in which hot soldering would be ineffective or impractical. The materials are said to offer thermal conductivity and can bond or seal electrical components or wiring in applications requiring heat dissipation. These low-shrink, nonshrink epoxy and epoxide formulations also mix and pour easily, fill voids completely and cure with minimal air entrapment.Devcon, Danvers, Mass.
ASSEMBLY TOOLS & EQUIPMENT
Modular ConveyorsModular conveyors are used in the design and manufacture of automated assembly equipment. The conveyors consist of a set of standard, pre-engineered and pre-tested building modules that reportedly include a conveyor, lift assembly with a standard mounting plate, a gate assembly, a touch screen HMI, a common PLC-based controls system, and mechanical and vacuum clamping. Using standard modules for all conveyors is said to reduce costs, increase response and delivery times, improve product reliability, quickly implement design improvements, and increase service training and product expertise. Palomar Technologies Inc., Vista, Calif.
CLEANING MATERIALS & EQUIPMENT
Aqueous CleanerAquaSonic AQE-NHR aqueous cleaner removes solder pastes and SMT adhesives from misprinted PCBs, stencils, printing equipment and more, without the need for heating the wash bath. Formulated from a blend of select nonionic surface-active agents and de-ionized water, the cleaner reportedly works at ambient temperatures, resulting in less evaporation, so the wash tank does not require replenishing as frequently as heated baths. The cleaner is said to be considered non-hazardous and compatible with many materials including stencil materials, screen emulsions, PCBs, plastics, cured solder mask, polymeric tank and plumbing materials. JNJ Industries Inc., Franklin, Mass.
INSPECTION EQUIPMENT
Solder Inspection SystemVT-WIN II PCB solder inspection system can be used either in-line or off-line for rapid, accurate identification of various circuit board assembly defects. Its zoom lens reportedly allows multiple magnifications down to 10 æm per pixel. The system is said to have advanced algorithms that enable proper inspection of leading technology processes, such as lead-free solder. The system's software, which is programmed via CAD placement data, also incorporates intelligent algorithms to reduce operator-programming time. Omron Electronics LLC, Schaumburg, Ill.
PICK-AND-PLACE
Modular Chip MounterCM402L modular chip mounter reportedly can produce 60,000 cph. The mounter features a flexible design and includes a cart for changing over all feeders as once, as well as external board support pin setup. Additionally, the chip mounter can be reconfigured from high-speed to multi-function head on-site, and is said to use five types of programmable pitch tape feeders from 8 to 72 mm. Panasonic Factory Automation Co., Franklin Park, Ill.
Component MounterRelease 2 of the Topaz-XII component mounter reportedly features a new camera, enabling it to place larger components up to 45 mm2 and 11 mm in height. The mounter is said to be capable of handling boards measuring up to 550× 610 mm. The existing Windows NT-based graphical user interface includes new operator functionalities, including the capability to optimize a production program while the machine is running, as well as edit the programs during operation.Assembléon, Eindhoven, The Netherlands.
SOFTWARE
Line-balancing SoftwareMYSpeed 2.4 optimization and line-balancing software reportedly offers an optimal kitting solution to maximize throughput, and allows production schedules to be planned accurately. With intuitive tools to assist the operator, instructions reportedly can be printed out, and balancing can be optimized. Functions include a new wizard for defining machines, a quick quoting process editor, more streamlined job preparation, and printed instructions and results. MYDATA automation Inc., Rowley, Mass.
Software LibrarySapera 4.1 is an enhanced software library for high-performance image acquisition, processing and analysis. This software reportedly incorporates a number of added support features that speed the application development process. The software includes the SMART series, a collection of robust application specific libraries for pattern matching (SMART search), OCR (SMART OCR), and 1-D/2-D bar codes (SMART Matrix).Coreco Imaging, Montreal, Quebec, Canada.
