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 Niton XL3 Series third-generation handheld XRF analyzer is said to provide the fastest solder alloy grade identification and laboratory-quality composition analysis of plastics and polymers. Typical time for routine solder screening measurements is said to be less than 5 sec. Features a 50 kV, 2W x-ray tube. Comes in a range of configurations with an assortment of optional features and accessories; quick screening to simultaneous measurement of up to 25 elements in a sample. Offers component testing; solder analysis; populated PCBs and finished goods; hi-reliability screening.

The CM8 PWB cleaner has elastomer rollers said to remove contamination to 1µm and transfer dry, unattached particles from the substrate onto pre-sheeted adhesive rolls. An anti-static system prevents recontamination of the board. Has a direct motor drive mechanism said to eliminate the need for drive belts or chains. Cleans a range of substrates and board thicknesses.

AVIA 355-14 is an intermediate power level model in a package optimized for micromachining at high throughput rates. Is an all-solid-state Q-switched laser said to generate more than 14W at 355 nm. Pulse duration is <30 ns and high beam quality is (M2 <1.3). Reportedly supports pulse repetition rates as high as 300 kHz. Long-lived pump diodes are field- replaceable. Frequency-tripling component has a projected lifetime of stable output power for more than 60,000 hrs. Includes Posilock beam position sensor and feedback system. Additional automation enhancements include total pulse control and a variety of pulse-shaping features. Applications include chip singulation, scribing and dicing of silicon and low-K materials, via drilling, and solar-cell micromachining.
