Description

Technical Field

[0001] The present application relates to the technical field of crystal bonding, and in particular to a high-speed crystal bonding machine with double dispensing heads. Background Art

[0002] Crystal bonding is a processing method that uses colloid to bond the chip to the designated area of ​​the crystal bonding bracket to form an electrical path. The usual crystal bonding method is that the feeding mechanism transfers the crystal bonding bracket to the working position on the fixture, and the dispensing mechanism first dispenses glue at the position where the crystal bonding bracket needs to be bonded to the chip. Then the crystal retrieval welding head moves from the origin position to the position to absorb the chip, and the chip is placed on the expander chip plate supported by the blue film. After the crystal retrieval welding head is in place, the suction nozzle moves downward, and the ejector moves upward to lift the chip. The crystal retrieval welding head returns to the origin position after picking up the chip, and then moves from the origin position to the crystal bonding position. After the suction nozzle fixes the chip downward, the crystal retrieval welding head returns to the origin position again. This is a complete crystal bonding process.

[0003] With regard to the above technical means, glue is dispensed once and then crystal bonding is performed. During the crystal bonding process according to this cycle, since the glue dispensing time in a single cycle is usually longer than the movement time of the crystal welding head in a single cycle, the crystal bonding efficiency of the entire equipment cannot be further improved.
