【Know Tungsten】Tungsten Probes for LED Chip Probing

LED chip probing and LED mapping sorting are necessary and important processes in the production of LED products. 

Probes are applied in the LED chip probing process, typically conducting tests and sorting based on key parameters such as electrical values, brightness, wavelength, ESD, etc., before proceeding to the encapsulation stage. 

Tungsten probes are primarily used on point testing machines, where the probe tip contacts the LED pad to provide current flow, causing the LED to light up for electrical testing.
