AI Technical Summary

Technical Problem

Existing technologies are unable to effectively detect and screen out pin bending anomalies in integrated packaged chips with asymmetric pins on both sides, especially SOP-type packaged chips, which may cause pin damage or detection failure.

Method used

An integrated packaged chip pin inspection device was designed. It uses an upper track and a lower track spaced along an inclined straight line, combined with a swing track and a clamping assembly. The pin bending state is detected by a pin detection frame, and defective chips are screened out by the rotation of the swing track. The screening is assisted by a proximity switch and an inclined air nozzle. The degree of automation is improved by combining a rotating plate and a detection assembly.

Benefits of technology

It realizes the detection and screening of abnormal pin bending of chips with asymmetric pins on both sides, improves the automation level of the device, ensures smooth detection and rapid discharge, avoids pin damage, and improves the reliability and efficiency of detection.

Abstract

An integrated packaged chip pin detection device, relating to chip packaging and testing technology, comprises: upper and lower rails spaced and fixedly arranged along an inclined straight line; a swinging rail rotatably connected between the upper and lower rails, with its axis of rotation located below and parallel to the width of the swinging rail; a pin detection frame mounted on the swinging rail and rotating with it, having a pin slot formed therethrough for detecting whether the chip pins are bent normally or abnormally; a drive mechanism mounted below the swinging rail for rotating the swinging rail; and a clamping assembly located at the lower end of the upper rail and in contact with the upper end of the swinging rail. This device automates the detection of abnormally bent chip pins and effectively screens out defective chips that detect abnormalities.
