Les propriétés matérielles du matériau de la buse SMT en céramique et en acier au tungstène sont presque les mêmes.
Selon l’enquête, La plupart d’entre nous utilisent maintenant des buses en acier au tungstène. Après une longue période d’utilisation, there will be bad phenomena such as wear and deformation.
Difference:
The ceramic suction nozzle is 3-4 times the service life of the tungsten steel surface plus black coating ceramic suction nozzle;
The ceramic vacuum nozzle is 2-2.5 times the service life of the so-called “diamond steel” et “black material” ceramic nozzles.
The use of ceramic suction nozzles: the main tool used for LED automatic die bonding machine to suck wafers and ic bare chips.
The performance of ceramic suction nozzles: durable, wear-resistant, high temperature resistance, high hardness.
Introduction of ceramic nozzles:
The ceramic suction nozzle improves the indentation caused by the high hardness of the tungsten steel suction nozzle when sucking the LED chip and the ic bare chip. It improves the yield of semiconductor packaging. The ceramic suction nozzle of the spectrometer makes it easier to absorb and transport chips. Reduce scratches long service life and durable. Widely used to pick up solid crystal LED and chip placement.
advantage:
1. The tip of the ceramic nozzle does not turn white (after half a year or even a year);
2. Ceramic nozzles are not electrostatically charged due to high speed in high-speed production;
3. It has higher wear resistance and longer life than tungsten steel or diamond.
