LED chip strength test device

Abstract

The invention provides a LED chip strength test device. The LED chip strength test device comprises a device main body; the device main body comprises a control bench; a control module and a button module are arranged in the control bench; a LED chip to be tested is fixedly arranged on a test pedestal; a gas cylinder is used for driving a pressing knife at the end part of a piston rod to press onto the LED chip through the piston rod, so that relatively real stimulation of the possible force bearing situations of the LED chip under different packaging conditions is realized; at the same time,a linear motor is used for pushing a sliding block, so that a test mechanism is capable of sliding along a slide groove, and the control module is used for controlling mutual cooperation of the linearmotor with the gas cylinder, so that multi-point strength test on different parts of the LED chip to be tested is realized, relatively complete strength performance parameters are obtained, production technology stability monitoring mechanism can be established by a chip manufacturing terminal based on the strength performance parameters, LED chips with preferable strength values are obtained viaselection and are discharged, and LED chip fracture of packaging application terminals is avoided effectively.

Description

technical field [0001] The invention relates to the technical field of LED chip performance testing equipment, in particular to an LED chip strength testing device. Background technique [0002] LED (Light Emitting Diode), that is, light emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. Compared with ordinary lamps (incandescent lamps, etc.), LEDs have many advantages such as energy saving, long life, strong applicability, short response time, and environmental protection, and with the improvement of the brightness of LED chips, it is the general trend for LED lamps to replace traditional light sources and enter the lighting field. With the rapid development of LED manufacturing technology, LED has been widely used in many fields, so the performance test of LED chip is of great significance to the application products of LED. However, with changes in market demand, technical changes in the packaging market, and the ...

AI Technical Summary

Problems solved by technology

However, with changes in market demand, technological changes in the packaging market, and the slimming of LED chip size design, LED chip breakage is more likely to occur at the LED packaging application end, which affects the packaging product yield and customer experience.

Therefore, the chip manufacturer is required to screen LED chips with relatively better strength capabilities for shipment and packaging applications. However, there is no test device that can effectively monitor the strength of LED chips in the field of LED performance testing.
