EP77M-F is a two-component, silver filled, electrically conductive epoxy adhesive for high-performance bonding. The compound has a low volume resistivity of 10-3 ohm-cm. It will set up in 5-10 min. at room temperature, even when applied in very small amounts. Full cure usually takes 8-12 hrs at room temperature. Electrical conductivity is first detectable within 30-60 min.
Has high bond strength to similar and dissimilar substrates. Adheres to metals, glass, ceramics, vulcanized rubbers and most plastics. Bonds are resistant to thermal cycling and chemicals including water, oil and most organic solvents. Has a service operating range of 4°K to +125°C.
Has a one-to-one mix ratio, by weight or volume. Can be applied with minimal sagging or dripping even on vertical surfaces. It is 100% reactive and does not contain any diluents or solvents.
Available in glass jars, metal containers or syringes.

CADSTAR 3D has been upgraded to include increased functionality and performance improvements.
New windows XP functions include drag and drop loading of designs, floating toolbars and modeless and dockable dialogues for Design Browser and DRC Results. Registration of file extensions with Windows Explorer allow a design to be opened by double clicking on its icon.
Design transfer has also been enhanced to optionally ignore objects on the inner electrical layers, which are unnecessary for carrying out 3-D checking functions, reducing memory required and increasing the application speed. STL file importing is reportedly up to 100 times faster, with design file sizes reduced by approx. 10%.
Other improvements include: custom views, new commands for grouping and ungrouping geometrical objects, and automatic selection of entities for DRC and collision check functions. Keepout volumes can be viewed in a semi-transparent format and a PCB design can be merged into an existing 3-D design, preserving enclosure positions.
CADSTAR 3D 4.4 is priced from $5,000. For more information, visit www.cadstarworld.com/3d

Self-clinching fasteners in the product line made from 400 series stainless steel include PFC4 panel fasteners, which incorporate captive screws to reduce loose parts; SO4 through-hole threaded standoffs (available unthreaded for spacing multi-panel assemblies); BSO4 blind threaded standoffs designed for stacking or spacing; and FH4 flush-head studs.
The product line also includes SP PEM 300 nuts, whose corrosion resistance is similar to 300 series stainless steel. All are machined from specially hardened stainless steels and can be installed permanently in stainless sheets as thin as .030”/0.8 mm.
Non-clinch fasteners for use in stainless steel include PFS SNAP-IN panel fasteners -- which can be installed without tools -- and PFF HYBRID floating panel fasteners featuring a flare-mount design to enable “floating” in mounting holes.

The system joins a host of recent introductions that has enabled the transition of the SlimKIC 2000 from primarily a reflow tool to a universal thermal process tool for cure, rework and wave solder.
Is designed to be used repeatedly in the wave solder machine. Holds the SlimKIC in place during each run to measure pertinent process data, including peak temperature, dwell time, parallelism and conveyor speed.

ProtoMat S62 circuit board plotter delivers prototyping capabilities at an entry-level price, reducing board production time while increasing overall accuracy and ease-of-use. Combining its maximum milling speed of 6" (150 mm)/sec. with its system resolution of 0.01 mils (0.25 µm) and 62,000 RPM spindle motor, the plotter produces extremely fine traces for all types of PCBs, including RF and microwave boards.
Has integrated head lighting and a 10-position automatic milling tool changer. Its motorized z-axis drive independently moves the plotter milling head over multiple axes, providing 3-D plotting capability for machining front panels and housings. Does not require external compressed air or chemicals, is enclosed by a soundproof acoustic cabinet. Optional accessories include a fiducial recognition camera system for automatic front-to-back alignment and an integrated vacuum tabletop for mounting PCB substrates on the plotter.
