Tokyo, Japan Advantest Corp. has introduced the M7522 dynamic test handler, which offers the industry's highest processing speed and positioning accuracy for fine-pitch tape automated bonding (TAB) and chip-on-film (COF) packaged devices used in LCD panels, according to the company.
With enhanced handling capabilities, M7522 dynamic test handler is said to deliver the industry's fastest index time of 0.7 seconds for improved test efficiency. The handler's newly-developed feed mechanism incorporates a high-performance servo motor, enabling an industry-leading 0.7-second index time for tape and film mounted devices.
In addition, the unit's optical lens, which locates the position of the device and the test probe, is now twice as powerful as Advantest's earlier model, offering a positioning accuracy of ±3 microns, which the company touts as the best in the industry. It supports fine-pitch LCD driver ICs required for increasingly high-definition LCDs, contributing to significant improvements in yield, said Advantest.
With the enhanced positioning accuracy of the M7522, high precision contact is possible even without test pads, said the company. Typically, contact between the device and the test probe is achieved through the use of test pads on the tape of the device. Once testing is complete, the test pads are removed.
In addition, the M7522 unit's new automated device and test probe positioning capabilities are said to deliver greater precision and eliminate the problems associated with manual operation. Automating the process also enables more highly accurate positioning to be achieved in a shorter timeframe, and the handler's precision contacts give it the ability to support many of the newer tape trends, Advantest said. In addition, checking for bends in the needle tip and cleaning operations can now be performed automatically by the unit as necessary, offering improved yields and a considerable reduction in working hours.
The M7522 dynamic test handler, together with the T6373 LCD driver test system, will be displayed as part of the company's LCD Driver IC Test Solution at the "Advantest Tour de Force 2008" exhibition at the Tokyo International Forum, June 3-5, 2008.
Pricing: From $240,000, depending on configuration.
Availability: August 2008.
