POLAR: NEW CITS880s - Controlled Impedance Test System

CITS880s system is the 9th generation impedance test system from Polar Instruments Ltd, UK. It is a solution for fabricators who need to measure impedance on fine traces and thin copper. CITS880s features Launch Point Extrapolation (LPE) that extrapolates the TDR response to a point close to the start of the transmission line effectively aloowing users to measure the instantaneous or incident impedance of the line more acccurately.

In addition to the LPE the CITS880s is also capable of measuring shorter traces - typically 2-3 inches shorter than previous generation of the CITS series. CITS880s now ships with completely re-engineered IPS and IPDS high speed probes whcih reassuringly are precision moulded with ESD dissipative materials to give maximum protection to your CITS.

Polar IPS and IPDS high speed probes are specifically desgined for CITS880s. They combine revised internals with more robust mechanical design and enhancements to the signal path, along with ergonomic precision mouldings in 100% ESD dissipative materials. IPS and IPDS probes are easily identified and contrast with previous generation probes by the use of the blue labels and blue resists on the probe tip interface.

PWB: IST - Interconnect Stress Test System

IST is an accelerated stress test method that overcomes the limitations of thermal oven or liquid / liquid methods, IST has the capability of effective / rapidly quantifying the integrity of both the Plated Through Hole (PTH) and the unique ability to identify the presence and levels of post separations within the multilayer board. IST creates a uniform strain from within the substrate, the interconnects ability to distribute and redistribute this strain provides an indication of integrity. The plated barrels and inner layer junctions are “exercised” until the initial failure mode/mechanism is uncovered.

Following several years of intense evaluation, the IPC have approved the IST technology as the first electrical test methodology for assessing plate through hole integrity and for the detection of post separation. The IST methodology is issued in the IPC-TM-650 Test Methods Manual.

IST has become the leading test standard for via and material reliability. Top OEMs, ODMs, CDMs, Material and PCB manufacturers around the world use IST technology to test new materials and processes.

PWB: DELAM - Dielectric Estimation and Laminate Analysis Measurement System

PWB Interconnect Solutions Inc. has developed a tool that automatically measures and analyzes changes in material properties that signify whether damage was caused by exposure to the elevated temperatures associated with component assembly and possible reworks. This unique technology complements their IST testing capability. The principles used by this tool have proven to be an effective methodology in determining whether the materials used in printed wiring boards are capable of withstanding the cyclic exposure to temperatures that exceed the materials inherent robustness.

The test system incorporates a high precision LCR (capacitance) meter which is interfaced to a user friendly application software, which automatically measures, records, analyzes, displays and reports all key test parameters

AET: Dielectrometer - Microwave Dielectric Meter

The key to successfully design of high speed PCBs is to know the right Dielectric (Dk) and tan Delta value of the pre-preg or core material used for manufacturing the PCB stacks. Currently designers / manufacturers rely on material data provided by the manufacturers. The Microwave Dielectrometer from AET, Inc enables fast and non-destructive measurement of dielectric materials of various shapes, including thin-films, by using an evanescent mode of an open coaxial resonator. A built-in feedback oscillator circuit enables accurate measurements with an easy step-by-step operation. Accuracy is achieved by combining a high Q cavity, a highly accurate measurement algorithm and the 3D electromagnetic simulation software.

AET: High Frequency Probe Station for measuring losses on PCBs

Measurement of losses on PCBs, connectors and ICs require careful set-up of high frequency probes to make accurate measurements using Vector Network Analyser (VNA) or Time Domain Refelectometer (TDR). The Probe station from AET, Inc. has a probing stage and a micro positioner that can be adjusted on the X-Y-Z-theta directions, and can probe samples of various shapes and sizes. A custom designed probing fixture allows the use of air coplanar, semi-rigid, or differential active probes. A TRL/LRM calibration kit are designed and manufactured. The probe station can be used for measurement of losses on PCBs and semiconductor wafers for RF circuits.

COMPIX Model 222 - Radiometric Thermal Imaging Camera

The 222 is a calibrated, radiometric, real time thermal imaging camera. It requires little power and needs no cryogenic cooling. It uses an amorphous silicon microbolometer detector and produces 160X120 pixel images.

In an IST evaluation, testing automatically stops when a circuit reaches a 10% increase in resistance. The failing coupons have circuits that are still electrically conductive but have a modest increase in resistance. Now, since the test stopped well before catastrophic failure it is still possible to identify the exact microvia that is contributing the highest resistance to the circuit using thermo-graphic techniques.

This process is called 'Failure Location' and involves the use of the 222. Since the failed circuit has only experienced a 10% change in resistance, a DC current can be applied causing the failing interconnection to heat. The compromised via has a higher resistance, compared to other connecting traces and so it will become the hottest structure in the coupon. The thermographic 222 camera allows direct visualization of the exact location of the hottest microvia. The worst case failing microvia is seen as high temperature hot spot on the surface, thus making the COMPIX 222 a powerful tool.
