Two-pair Connector
The GbX two-pair connector targets designs with tight slot-pitch constraints such as those in the blade server market. Designed for high performance within a small footprint, the connector features 27.5 real differential pairs per linear inch to fit into a 15-mm slot pitch. Delivering electrical performance and enhanced signal integrity with 100-Ω matched differential impedance and cross talk under 5% at a 50-ps rise time, the modular design allows for configuration in conjunction with low-speed signals. Teradyne Inc., Nashua, N.H.
Image Sensor Sockets
A series of image sensor sockets designed to protect sensors from damage during board assembly and production is available in standard, footprint-specific and custom configurations. Features include screw-machined terminals and multi-fingered contacts. Standard sockets are available in FR-4 insulators for thru-hole and surface mount designs. Other options include molded or peel-a-way insulators and lead-free designs. By inserting after the reflow solder process, the sockets can protect sensor performance. They also can eliminate sensor damage caused by prolonged exposure to heat and errant solder flux on glass components during board assembly. Advanced Interconnections Corp., West Warwick, R.I.
Laser Scanner
The battery-powered ModelMaker Z series laser scanner allows up to two hours of remote operation and can be controlled via laptop for full portability. Enhanced sensor performance (ESP) enables on-the-fly sensitivity for a reduction in erroneous data. Adaptive laser power (ALP) automatically changes laser intensity and may improve performance. Using three available sensors, the scanner captures over 23,000 pps. The system uses a portable CMM with an attached 3-D laser sensor, PC and ModelMaker Software that enables full model editing, polygon reduction and data output to all standard 3-D CAD and inspection packages. NVision Inc., Southlake, Texas
Screen & Stencil Printer
The ASP02 in-line screen or stencil printer has an optical positioning system for ceramic substrates, LTCCs, glass plates, stiff and flexible materials, PCBs and other flat, printable materials with pastes, adhesives, paints and lacquers. The machine has a maximum print format of 300 x 300 mm and an independent frame. Cycle time is 3.5 seconds; and print time and statistical process control enables error analysis and machine running times in tabular or graphical form. ASYS Automation LLC, Suwanee, Ga.
ASSEMBLY TOOLS & EQUIPMENTPCB Handling Systems
The Model 80 Karry-All system can store and transport up to 450 circuit boards in less than 6 sq. ft. of floor space, making it suitable for active manufacturing environments. The system consists of a sturdy, vertical transport cart with wire slide assemblies along the sides to hold three racks on each side. The cart measures 72" high and comes in three widths, depending on rack size. Carts feature 5"-diameter polyurethane casters and a grounding chain for ESD protection. Constructed of two conductive, injection-molded side panels with reinforced ribbing to prevent flexing, the panels also have 75 slots that measure 0.110" x 0.155" on a 0.210" pitch with thumbscrews for adjustment. Fancort Industries Inc., West Caldwell, N.J.
CLEANINGAll-purpose Cleaner
Cybersolv is a low-VOC, water-based, all-purpose aerosol cleaner that removes dirt, oil, grease, wax, flux, paste and adhesive from multiple surfaces. Made from renewable resources and based on clean, effective compounds, the cleaner also is biodegradable. Low vapor pressure and high flash points allow formulations to operate in under-screen cleaning applications safely. The cleaner’s solvency makes it suitable for use in a range of cleaning applications. Kyzen Corp., Nashville, Tenn.
CONNECTORSBoard-to-Board Connectors
A series of low-profile board-to-board connectors are available for applications requiring low profile, compact footprint interconnects between PCBs or components. A 0.8-mm, low-mated height is available in custom, flexible footprint configurations from less than 10 to over 2,000 contacts, with spacing as close as 1.0 mm. The series provides high-speed performance and supports signal speeds in excess of 20 GHz, with contact resistance less than 25 mΩ. Using CIN:APSE contact technology, a solderless, wound-wire contact, the connectors are said to ensure reliability in applications such as high-end computer servers and military-jet aircraft. Cinch Connectors, Lombard, Ill.
DISPENSING EQUIPMENTCartridge Dispensing Systems
MIXPAC handheld cartridge dispensing systems offer a choice of manual or pneumatic dispensing gun, cartridge and static mixer - designed to work as integrated, high-performance systems. Used to dispense two-component adhesives, a variety of volumetric ratios, such as System 50, System S-50, System 200 and System 400 are available. The system uses the same twist-and-lock static mixers as the company’s 50-ml cartridges. Benefits include hazardous and material waste reduction. ConProTec Inc., Salem, N.H.
HARDWARELead-free Switches
Illuminated pushbutton switches have a 6-mm height and a right-angle actuator with an integral central LED, removing the need for a separate LED, right-angle holder or light pipe. The mechanical design of the switches prevents misalignments. Actuator extensions may be added to meet particular aesthetic requirements. Without actuation, latching versions must always extend out of the front panel by 0.220" per min. The single-pole, double-throw contact allows for normally closed and open configurations. ITT Industries Cannon, White Plains, N.Y.
MATERIALSDesiccants
Custom-manufactured multiform sorbents are available in several shapes to fill dead space within electronic housings, removing ambient moisture. They can be formulated to maintain and control equilibrium relative humidity (ERH) within a structure or package, and incorporate into existing design specs to safeguard circuit boards, semiconductors or other electronics applications. The sorbents soak up volatile organic compounds (VOCs), volatile acids, alkaline substances, oxygen and carbon dioxide and can be custom-sized to safeguard LCD and organic light emitting display (OLED) screens against moisture degradation. This avoids malfunctioning pixels and dark spots. Multisorb Technologies, Buffalo, N.Y.
Wave Solder Flux
The WF-7742 wave solder flux for lead-free is formulated for surface mount, mixed-technology and thru-hole electronics assemblies. It is a water-based and non-flammable flux that eliminates VOC emissions and special storage requirements. The flux also offers a wide process window that provides above-average solderability on difficult-to-solder assemblies during extended dwell times. Indium Corp. of America, Clinton, N.Y.
PASSIVE COMPONENTSThin Film Resistors
