Continuously measure the micro-resistance values of solder joints and connector connections. Efficiently evaluate the reliability of the connection parts.
Under low and high temperature cycling environments, the minute resistance values of solder joints and connector contact conductors are continuously measured. A system for automatic measurement, data recording, and data processing using a computer has been realized. This allows for more accurate and efficient evaluation of connection reliability, including graphing of data and compatibility with spreadsheet software, as well as data processing via LAN. 【Features】 ■ Equipped with a unique multi-scan method and measurement instruments compliant with international standards ■ Two types: DC current application method and AC current application method ■ Two types of fault determination: absolute value judgment method and change rate judgment method ■ Real-time measurement on a computer, with data editing and viewing possible during measurement ■ Significantly improved testing efficiency through integration with a thermal shock device *For more details, please refer to the PDF document or feel free to contact us.
