Description

An LED pin soldering pull test device Technical Field

[0001] This utility model relates to the field of LED production and processing technology, specifically to an LED pin welding tensile testing device. Background Technology

[0002] LED is an abbreviation for Light-Emitting Diode, a solid-state semiconductor device that converts electrical energy into visible light; LED pins are the parts that connect the LED device to external circuits.

[0003] As a crucial component connecting the LED to external circuits, the stability of the LED pin connection directly impacts the stability of the LED circuit. Therefore, a pull test is necessary at the LED pin solder joint to ensure that the LED pin's stability meets requirements. Currently, pull tests for LED pin solder joints commonly employ a push-pull force gauge. This involves placing the LED board under the gauge and then pulling the pin until the solder joint breaks. The value displayed on the gauge at this point represents the pull force that the solder joint can withstand.

[0004] However, current LEDs are very small, and the LED pins are even smaller. When conducting tensile tests, it is very difficult for staff to observe them visually and cannot directly see the specific condition of the pins. Furthermore, when the LED is subjected to tensile force during the pin test, it is also subject to a certain amount of tension, which can easily cause the LED to shake or shift. This can cause the position of the push-pull force gauge to deviate from that of the pin. Since the pin is very small, staff cannot accurately know the positional deviation, resulting in inaccurate data from the pin tensile test. Summary of the Invention
