Products Description Welding principle: This machine uses the principle of ultrasonic friction to realize the surface welding of different media, which is a physical change process. First, the first end of the gold wire must be processed to form a spherical shape (this machine adopts negative electron high pressure to form a ball), and the welded metal surface is pre-heated;Then, under the combined action of time and pressure, the gold wire ball produces spontaneous deformation on the metal welding surface, so that the two media can reach reliable contact, and through ultrasonic friction vibration, the two metal atoms are formed under the action of atomic affinity. The metal bond realizes the welding of the gold wire lead. Gold wire ball bonding is superior to silicon-aluminum wire bonding in terms of electrical properties and environmental applications. However, since the welding parts made of precious metals must be heated, the application range is relatively narrow. Introduction: This pull tester is designed for testing the pull strength of the wire and the push strength of the gold ball on the chip and the die bonding strength(COB). Specification: Dimension:350mm*400mm*500mm Power in:220V Power:5W Microscope:15/30X OR 20/40X Push strength range:0-5000G(accuracy: 0.001KG)Meter brand:SP Pull strength range:0-30G(accuracy:1G)Meter brand:DESK Jig:depend on product(standard jig: COB, DIP,SMD,High power LED) Precision lead screw:stroke:200MM Micrometer:0-25MM(2 pcs) Precision slide:4PCS Weight:30kg
Operation: 1,put the product to the jig; 2,adjust the meters to zero; 3, under the microscope, turn the hand wheel slowly, so to push the product to close to the meters; 4, align the probe or hook on the meter to the gold ball or wire. 5, turn the micrometer slowly, the meter can get a value of the strength. be careful of the strength range of the meter!
Application Gold wire ball bonding machine is mainly used for LED, chips, diode, laser tube, the inner lead, semiconductor devices etc. Sample
