LED chip anti-breaking strength testing device

Abstract

The invention provides an LED chip anti-breaking strength testing device, including a device main body. The device main body includes a control desk provided therein with a control module and a key module. A to-be-tested LED chip is fixed on a testing seat, and a drive motor gradually pushes the testing seat towards the direction of a testing mechanism. A pressing knife of the testing mechanism ispressed on the to-be-tested LED chip under the action of a cylinder, and the possible force conditions of the LED chip under various package conditions can be relatively truly simulated. The controlmodule controls the drive motor and the cylinder to cooperate with each other, thereby performing multi-point anti-breaking strength testing on various parts on the to-be-tested LED chip, to obtain complete anti-breaking performance parameters. A chip manufacture end can establish a manufacture process stability monitoring mechanism based on the anti-breaking performance parameters, thereby screening out LED chips with better anti-breaking values for sale, so as to effectively reduce the LED chip breaking phenomenon at package application ends.

Description

technical field [0001] The invention relates to the technical field of LED chip performance testing equipment, in particular to an LED chip anti-fracture 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 ma...

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 fracture resistance for shipment and packaging applications. However, there is no testing device in the field of LED performance testing that can effectively monitor the fracture resistance of LED chips.
