Application: RF shield,TOSA.ROSA,QSFP.BOSA,TO.
1. Equipment function:
Power-on self-test: All moving axes of the equipment shall automatically reset and self-test when powered on.
(1) Suitable for sealed welding of metal shells of materials such as aluminum alloy, aluminum silicon alloy, nickel alloy, stainless steel, kovar alloy, carbon steel, copper alloy (such as oxygen-free copper shell) and titanium alloy.
(2) Laser welding is a non-contact welding process that only requires entering the welding area from one side of the welded part.
During the laser welding process, the dense laser beam causes the material temperature to rise rapidly, and its speed is usually measured in milliseconds.
Laser welding can complete three types of welding: conduction welding, conduction/deep penetration welding and deep penetration/"keyhole" welding.
Conduction welding has low working energy consumption and can form a wide and shallow weld nugget.
Conduction/deep penetration welding uses moderate energy density and can form a deeper weld nugget.
Deep penetration or keyhole welding requires energy to be directly injected into the material to be welded, thereby forming a deep and narrow weld nugget.
(3) Configure vacuum heating box, discharge bin and other auxiliary equipment according to customer needs. This machine improves the automation of the production line, reduces the labor intensity of employees, improves production efficiency, and reduces the impact of manual intervention on materials.
