surges. The same HV tests can also highlight issues with the sharing of signal and power lines within the same connector, and within connec- tors of compact pitch.
www.us-tech.com PC-based cable testers can
switch readily between testing two- terminal components, such as trans- formers, and multiconductor cables and harnesses, as well as applica- tions with voltages up to 2,100 VDC
or 1,200 VAC. CableEye can also measure
leakage currents, which is especially useful when determining whether borderline DWV or IR results are an issue. The same user interface appears with the same test princi- ples for HV testing multiconductor setups. In this case, the cables con- nect to the tester with interface boards, or by interface harnesses, such as an AMPMODU cable.
In-Plant Scenarios Thorough testing of a product
starts at the design verification and prototyping phases. Early feedback of the results allows for improved design for manufacturability and saves money by catching problems earlier in the workflow. Typically, harnesses and cables
destined for medical devices and equipment are tested within an envi- ronmental chamber where the rigors of transportation and a life of opera- tion in a variety of operational tem- peratures, humidity and vibration can be simulated. These tests cover aspects of safety, reliability and accelerated aging. The same PC-based testers used
NEW CrimpCenter 36 SP High-Performance, Fully Automatic Crimping
The new CrimpCenter 36 SP builds on the already impressive features and functionalities of the CrimpCenter 36 S. It offers decreased set-up time, increased possibilities allow for a variety of applications to be processed with cross sections 0.13 to 6 mm² (26 - 10 AWG) and features all of the latest quality assurance options, such as SmartDetect, WireCam and the Guided Feasibility Study. These features, along with an attractive price point, make the CrimpCenter 36 SP an ideal machine for complex production and quality targets.

for continuity and HV tests on the pro- duction line are flexible enough to be integrated into these test systems. They can accommodate long test inter- faces between the tester and environ- mental chamber electrical ports to which the cables under test within the chamber are connected. The prototyping stage is also the
prime time to develop test automation processes for the production line. For more efficient testing, many manufac- turers automate continuity and HV testing. With PC-based testers, they can incorporate external relay boards to automatically switch between dif- ferent circuits during test, or to oper- ate lock and release latches, use API or LabVIEW interfaces to integrate with other equipment, scan ID badges for operator login, scan work orders for automatic tester set up, connect foot pedal or remote controls, and add a variety of audible and visual

pass/fail external indicators, such as tower lights. Test procedures are programmed
in a simple scripting language that includes calls to automatically log the test data for statistical process control and to print graphical test reports. Macros can be triggered by a test pushbutton, a peripheral such as a foot pedal or a relay closure. Today’s electronic equipment is
demanding smaller-volume electronic designs with ever greater functionali- ty. This is driving the development of systems that must be more carefully checked for continuity and insulation integrity. Using finer-pitch connectors brings a higher chance of faults. An enhanced continuity check
tests for opens, shorts, miswires, and intermittent faults, and HV tests can be used to check insulation integrity. Contact: CAMI Research, Inc.,

What’s Next for Visual and Optical Inspection?

greater traceability and control of operational tasks of users with dif- ferent skill levels. Optically, digital inspection sys-
tems offer a much larger field of view than can be seen or imaged using a traditional stereo microscope. This is done by matching the objective lens to the camera sensor, thus maximiz- ing the resolution in the resulting image, and exploiting the large diam- eter of the objective for a wide field of view. Another benefit of digital sys- tems is the large magnification range which allows users greater flexibility than traditional optical systems. Digital systems also reduce neck,
back and eyestrain by showing the image on a large screen, allowing for greater adaptability for multiple users, plus greater ergonomics through a more natural and comfort- able operating position. The ergonom- ic design of digital microscope systems makes them excellent for high sample throughput inspection processes. Standalone digital inspection
and measurement systems, such as the Omni from Ash Technologies remove non-value add steps from inspection processes and offer a wide range of capabilities that help cus- tomers to improve workflow efficien- cy and quality control. Digital inspec- tion systems may cost more than tra- ditional stereos, but the benefits in automation, efficiency and repro- ducibility may make that a trade-off worth considering.
