Abstract

Docking system is of vital importance in the HP93K platform, the precision, flexibility and stability of the docking system directly influence production test efficiency. This paper introduces a tester & handler auto docking system based on infrared measurement principle. It uses an infrared emitter-receiver as a front-end distance acquisition system, and transmits the data to the MCU (main control unit) through a communication module. The MCU controls motor to dock tester and handler according to the real-time distance collect signal.

HP93K tester and handler auto docking system

Abstract

Docking system is of vital importance in the HP93K platform, the precision, flexibility and stability of the docking system directly influence production test efficiency. This paper introduces a tester & handler auto docking system based on infrared measurement principle.  It uses an infrared emitter-receiver as a front-end distance acquisition system, and transmits the data to the MCU (main control unit) through a communication module.  The MCU controls motor to dock tester and handler according to the real-time distance collect signal.

Body

At present, docking system needs manual operate in production line.  Using the old method will take more time and manual labor to dock tester. The important point is that connection error of manual docking may be have some influence for those sensitive contact testing. In order to fix these problem, a new auto docking system was designed. Infrared measurement technology was applied to measure distance between tester and handler. Refer to the figure 1, emitter send a signal and receiver receive the reflected signal. Then the distance can be calculated by the receive signal time. Handler should have a certain position and tester should also have a certain position range before positioning, or the alarming system will work. In order to capture handler position, three infrared emitter-receivers installed on tester to measure the distance between tester and handler. Refer to figure 2,...
