摘要:
The invention provides a mounting method capable of coping with high density mounting, narrower pitch mounting, cavity mounting and the like. In this method, displacement amounts of a chip that is picked up from a wafer by a pick-up nozzle to be held by the pick-up nozzle, with respect to a reference attitude, are obtained, and when the chip is delivered to a mounting nozzle for actually mounting the chip onto a substrate, the displacement amounts are corrected while taking the displacement amounts into consideration, so that the mounting nozzle always holds the chip in a fixed attitude.

摘要:
Provided is a mounting apparatus which enables high levels of both maintenance/improvement of product quality and reduction of product cost by reliably preventing accidental contact of a mounting part with a mounting target part while enhancing the productivity. In S1, a contact detection start position Hs0 is set. In S2, a chip holding tool chucks an electronic part. In S3, S4, the tool is moved to a transfer position A, and then the tool is lowered to the Hs0 from the transfer position A. In S5, after the tool is lowered to the Hs0, the lowering speed is changed to a contact detection speed. In S6, it is determined whether or not the electronic part has come into contact with a substrate. If the result of the determination is YES, in S7, the lowering of the tool is stopped. In S8, the actual contact position Hc is measured. In S9, the next contact detection start position Hs1 is set, and Hs1 is set to Hs0 (Hs0-Hs1) so that the later steps reflect this setting. In S10, S11, after the electronic part is joined to the substrate by ultrasonic bonding, the tool is transferred to the transfer position A. In S12, it is determined whether or not a stop command is issued. If the result is YES, this flow is ended. If NO, the procedure returns to S2, and bonding is repeated.
摘要:
The present invention has as its object to realize both of the higher accuracy of the detection of contact between a mounting part and a part to be mounted and an improvement in the stability of the detection at a high level. For this purpose, the present invention is comprised of a contact start detecting member designed to move in operative association with moving means for moving at least one of the mounting part and the part to be mounted toward the other until the mounting part and the part to be mounted contact with each other, and on the other hand, when the mounting part and the part to be mounted have contacted with each other, to have its operative association with the moving means released in response to the action of the contact pressure thereof and be movable independently of the moving means, and contact start detecting means for detecting the movement of the contact start detecting member to thereby detect the start of contact between the mounting part and the part to be mounted.
