SIwave v3.5 is a full-wave electromagnetic field simulator optimized for signal-integrity, power-integrity, and electromagnetic interference analysis of high-speed PCBs and IC packages. Features a finite-element-based DC solver optimized for extraction of power rail geometry in low-voltage/high-current PCBs and packages. Engineers reportedly can view voltage and current distributions in all relevant geometry, including vias and bond wires; have access to voltage drop and current flow information through vias, bond wires, sources, resistors, inductors, etc. in tabular format. Said to simulate electromagnetic behavior of complex PCBs and IC packages, including multiple, arbitrarily shaped power and ground layers, and any number of vias and signal traces. Full-wave S-, Y- or Z-parameters or GHz-bandwidth circuit model is used in concert with time- and frequency-domain analyses within Nexxim and DesignerSI or third-party SPICE-compatible circuit tools. Highlights include 64-bit capability; frequency-dependent source implementation; linear interpolation; frequency-dependent material model (Djordjevic-Sarkar); visualization of near E and H fields, and clip design tool.

The SmartStream pump is said to eliminate striking of a piston to a seat or nozzle. Each cycle displaces a column of material, rather than a single sphere. Cycles at frequencies that create a stream of material that reportedly can deliver increased flow rates (greater than 70 ÿl/sec). The displacement piston, driven by a linear motor/encoder assembly, is carbide. Design allows for easy removal and cleaning of the fluidic module. Only three o-rings need to be replaced. Z travel of dispense head is said to be virtually eliminated, as material is released from a nozzle 2-3 mm above the PCB surface. Reduces number of height senses needed.

SMP300 screen printer has a three-stage conveyor to eliminate additional buffer units. Features a patented clamping process to ensure the board is in the proper plane. Uses two CCD cameras to view and teach fiducials for aligning the board to the stencil within ±0.025 mm. Has a closed-loop, pneumatically controlled print head, and comes with 2-D post print inspection and automatic wet or dry stencil cleaning. Prints for 01005 pads.

The M3i provides materials management and printing capabilities. Is comprised of materials management cartridges, a ProFlow enclosed printer head, and Europa printing platform. Offers programmable ratio mix control and imaging of a variety of materials. Materials are preloaded into climate-controlled cartridges and stored at low temperature, then heated within the print head when elevated materials temperatures or melting processes are required. Is said to be completely scalable and can be used for underfill, encapsulation, solar cell and fuel cell imaging. Said to be fully automated and programmable; throughput is improved; operator intervention errors are eliminated; waste is reduced.

The Symbion P36 Plus AOI features 3-D and 2-D detection and is said to provide 100% volumetric solder paste inspection accuracy. Enhanced with latest architecture and high-powered processing capabilities. Includes process control software. Has central data hub where all relevant data are stored. Automatically links post-reflow AOI inspection data with solder paste inspection data and SPI results with paste printer machine events. Alerts when processes are out of operator-defined parameters and can stop a related machine.
