A print test device for testing the substrate after solder printing measures a height position of a height measurement point set on the upper surface of the substrate 4 by a height measuring machine 22 and outputs a measurement result as substrate height data. In a component placing step using an electronic component placing device, a control parameter for controlling a component placing operation of the placing head 32 is updated.

Abstract:
An electronic parts mount apparatus for taking out semiconductor chips from a semiconductor wafer held on a wafer hold section by a transfer head comprising a plurality of suction nozzles and transporting and mounting the semiconductor chips to and on a board has a parts recognition camera disposed in a manner that it can advance to and retreat from the wafer hold section for picking up an image of the semiconductor wafer. A parts mounting step for mounting a plurality of semiconductor chips on the board by the transfer head and an image picking up step for picking up a plurality of semiconductor chips to be next taken out by the parts recognition camera are performed concurrently. Thereby, the number of electronic parts per mount turn can be increased, the tact time can be shortened, and the electronic parts can be efficiently taken out and mounted on the board.

A plurality of mounted heads are provided on the index rotary member for sucking electronic components, and for mounting the electronic components on a printed circuit board. The mounting heads are vertically moved through a stoke relative to the printed circuit board. The stroke of movement of the mounting heads is adjusted. A vertically-movable table is provided on a horizontally-movable table. Clampers are supported on the vertically-movable table for holding the printed circuit board therebetween. The vertically-movable table is vertically moved to adjust a height of the printed circuit board held between the clampers.
Abstract:
An electrical component placing apparatus having a rotary head is required to be further accelerated to place an electrical component. In order to accelerate the operation of the placing apparatus, the indexing speed of the rotary head must be accelerated. However, since the rotary head is heavy, its rotating inertial is large. Thus, when the indexing speed of the rotary head is accelerated, a vibration at the time of stopping indexing of the rotary head is increased as well. Therefore, mistakes of picking up the electrical component by the pick and place head and placing the electrical component on the substrate occur. This invention reduces the outer diameter of a rotor for indexing a pick and place head smaller than the diameter of a guide for guiding the indexing of a pick and place head, disposes a bracket for supporting the pick and place head along the wall surface of the rotor and reduces the rotating diameter of the pick and place head smaller than the diameter of the guide. With the arrangement described above, the rotary head is reduced in size to largely reduce its weight and to reduce the rotary inertia of the rotary head. Therefore, the rotary inertia of the rotary head is reduced, and the vibration of the pick and place head at the time of indexing is reduced. Consequently, the rotary head can be indexed at a high speed, thereby placing the electrical component on the substrate at a high speed.

Abstract:
An electronic components mounting device has a plurality of feeder bases attached with tape feeders thereon, and a guide rail and a cylinder for drawing each of the feeder bases independently to a position for replenishing electronic components. When an electronic component runs out of the storage, only the feeder base that is carrying the relevant tape feeder gone out of the stock is drawn to a place for parts replenishment; in the mean time, the mounting actions keep on going by making use of tape feeders attached on other feeder base. Machine stop times can be decreased with the mounting device.
Abstract:
A type of electronic components mounting apparatus is widely known, by which electronic components on an electronic components feeding device are picked up, while pick-and-place heads are being rotated for indexing along a rotary head, and the electronic components are mounted on a circuit board or a substrate positioned on an X-Y table. The electronic components feeding device moves the tables with feeders over a base in lateral direction to supply the electronic components to the feeders on the pick-and-place heads. With increasing demands on high-speed mounting of the components, the moving speed of the above tables must be increased to attain high-speed mounting. The electronic components feeding device according to the present invention comprises a plurality of tables where feeders of the electronic components are placed, a base where these tables are placed, a first feeding means for moving said tables in lateral direction along which said tables are arranged in a feeding area at central part of said base in order to stop said feeders at pickup position of said pick-and-place heads, and a second feeding means for moving said tables between retreat areas on the sides of said base and said feeding area. As the result, the tables can be moved at high speed and can be stopped at correct position with high accuracy.
