High-speed Data Connector
 |
The Ultra-SCSI-II Shielded Connector, for use in high-speed SCSI-II data storage applications, is said to combine data, control and power in one compact connector body. The need for on-board ferrite beads and other RFI shielding and control devices on the PCB is said to be eliminated because RFI shielding is an integral part of the connector. It features 68 shielded data contacts, rated at 1 A each; 14 user-control contacts located on 0.1" centers; and four power contacts, rated at 4 A each on standard 0.2" centers. Ranoda Electronics Inc., Tracy, Calif.
Electrical Connectors
 |
The 320IEC13 and 320IEC15 Connectors are built to IEC publication 60320 and designed for applications subject to harsh handling and environments. The rewireable connectors can be used to supply power to a range of electronic equipment. They use terminals that have collar lug overleaves that "lock up" as the contact tangs tighten down on the wires, which is said to virtually eliminate the need to retighten the terminals. Marinco Specialty Wiring Devices, Napa, Calif.
Surface-mount Adapters
 |
Footprint Conversion Adapters for surface-mount devices are said to allow users facing IC shortages or obsolescence to use a similar device in a different package style without respinning the motherboard. The products are said to allow for conversion of almost any surface-mount device footprint to another, including QFP to BGA, BGA to BGA and TSOP to SOIC adapters. For volume applications, they can be packaged for use with standard pick-and-place equipment. Interconnect Systems Inc. (ISI), Camarillo, Calif.
Connector Boots
 |
Custom Connector Boots are produced in a variety of materials including silicone rubber and EPDM. In these formulations, the moldings are said to offer low-temperature flexibility, outdoor weathering resistance and the ability to hold up to high temperature extremes. All products are reportedly produced under strict tolerances and tooling is done at the company's mold shop. MOCAP Rubber Products Group, St. Louis, Mo.
Cordsets
 |
Medical-grade Cords meet the require-ments of UL-817 and are CSA-certified. The plugs feature solid nickel-plated pins, crimped connections, a glass fiber reinforced plug base and a semirigid PVC overmold with reported good strain relief qualities. The connectors are said to be double-insulated with float-ing phosphor bronze contacts. The products are available in clear or color-matched overmolds. Feller U.S. Corp., Somerset, N.J.
Reflow Encapsulant
 |
Se-Cure 9120 Reflow Encapsulant is designed for use in attachment of flip chip/CSP devices to circuit card assemblies. The single-pass product is said to achieve reflow and encapsulation in a single SMT reflow step, without a further secondary cure operation needed to fully polymerize the material. The product reportedly eliminates process time associated with traditional underfill process methods and reduces the equipment required for assembly. Kester, Des Plaines, Ill.
Test System
Model 933A Life-cycle Test Station reportedly counts over 4 billion successful/failure strokes and measures contact bounce time and contact closure resistance of connectors, switches, keyboards and keypads. It can be used in standalone mode or can be set up, started and stopped via a PC using Windows. Electrical load is selectable, force and velocity are adjustable, and it is programmable under a range of conditions. Tricor Systems Inc., Elgin, Ill.
Cutting and Forming Machines
 |
Superform Series Machines are said to cut only or cut and put a lock-in on taped radial components such as capacitors, resistors and transistors. For taped axial components, a variety of forms are available for vertical, horizontal, surface-mount assembly, standoffs and lock-ins. The units are hand-operated with an optional motor, and can cut, trim and form taped and loose-piece radial components. A variety of standard and custom dies are available for forming different types of shapes, standoffs and lock-ins. Tomken Industries Inc., Norwalk, Conn.
Adhesive
 |
CornerBond 3515 is a single-component liquid epoxy adhesive that is designed to minimize the effect of induced stresses between the PCB and the array package. It can be applied using standard SMT dispense equipment and cured during the solder reflow cycle. It breaks down at temperatures exceeding the standard solder reflow temperature of 200°C, allowing for removal and replacement of surface-mounted components. Loctite Corp., Rocky Hill, Conn.
RJ-45 Connectors
 |
PulseJack RJ-45 Connector Modules with integrated magnetics for 10/100 Base-TX network interface cards utilize an interlock base construction that is said to minimize the stresses of human handling, resulting in uniform positioning of coils, leads and interconnecting wires. The tab-down, through-hole mounted, single-port jacks integrate the magnetics, resistor and capacitor termination circuits, LED indicators, and RJ-45 receptacle into one package. They are compliant with IEEE 802.3. Pulse, a Technitrol Co., San Diego, Calif.
Electronic Coating
Novec Electronic Coating EGC-1700 is a used as protective coating and surface modifier for PCBs and as an anticorrosion/antimigration coating for electronic components and equipment. Coatings are said to air dry in 15 to 20 seconds, and it is generally not necessary to mask off friction-fit connectors before coating with the product. Reportedly, the thinness allows components to be easily repaired or reworked, and the coating adds no mechanical cure stress on circuit components. 3M Performance Materials Div., St. Paul, Minn.
Measuring Tool
 |
The Fischerscope X-ray XDVM-W measures the coating thickness and alloy composition of metal-coating systems. It is said to be suitable for high-volume coating thickness measurements on screws, connector contacts, contact strips and PCBs. The system measures according to test method ASTM B568 or DIN 50987 and ISO 3497. Features include a solid sheet metal housing and access to the large, slotted measuring chamber. Fischer Technology Inc., Windsor, Conn.
Micro Sandblaster
 |
The Swam Blast Line of manual and automatic micro sandblasting systems is said to selectively and safely remove conformal coatings, solder mask and oxidation, component demarking, deflashing, PCB rework/repair, and surface texturing. This is done by introducing abrasive powder into a controlled stream of compressed gas through a miniature nozzle. Nozzles from 0.006 to 0.090" and powders from 12 to 250 mm are available. Crystal Mark Inc., Glendale, Calif.
Interconnect
For this Interconnect Product, the conductive polymer consists of a fine-pitch matrix and gold-plated wires. The wires are embedded either straight or at a 63° angle in a soft insulating sheet of silicone rubber. The design is said to offer a high-density array of flexible contacts, which are suitable for electrical testing of SMT IC packages, such as BGAs, LGAs and QFPs, and also for low-profile electrical connection of PCB to PCB and FPC to PCB. Connect2it LLC, Incline Village, Nev.
Liquid Dispenser
 |
The DSP501A-4 Dispenser features multiple-nozzle liquid dispensing through one, two, three or four nozzles simultaneously. With timing intervalsfrom 0.01 to 30.0 seconds, it can dispense microdots or be used for potting components. It also includes a vacuum system on the fluid line for nondrip application of low-viscosity fluids. Applications include electronic components and assembly, medical devices, computer and disc drives, and optical items. I&J Fisnar Inc., Fair Lawn, N.J.
Masking Tape
 |
Scapa 581 is a polyester-backed plating tape coated with a high-performance silicone adhesive that can withstand an operating temperature up to 350°F. Said to be highly resistant to plating and stripping chemicals, the product can be used in direct immersion applications or for fume/splash protection. It is reportedly suitable for use with automatic taping machines, and removes cleanly after processing without leaving a residue. Scapa Tapes North America, Windsor, Conn.
SMT Headers
 |
Surface-mountable PCB Headers are said to improve solder joint strength in PCB applications through enhanced capillary action of reflowing solder. The capillary action of the solder paste during reflow draws the header down tightly to the PCB, creating a thinner, stronger solder joint. The design is also said to provide a way for solder gases to escape. The headers are available in a variety of pin lengths and sizes, and provide resistance to thermal shock and thermal cycling. Zierick Mfg. Corp., Mt. Kisco, N.Y.
