4.7 Maintenance Opening Detection Sensors

These sensors are used to stop the X/Y beam movement to avoid danger when

a foreign substance (a hand, a finger, etc.) is detected between the supply cover

and the feeder during operation.

When one of these sensors is turned off (E/R:

Light Emitted and Received) while the X/Y beam

is moving, the following measures are taken.

•

The power to drive both X/Y beams (Sides A

beam and B beam) is shut off.

Scope

9910-001 1-1 Tg0246-PM-OP

1. Scope of Machine

This latest and most powerful machine in new generation is provided with an

image recognition device which uses 2-beam, 4-head, and 4-camera system and

can place standard components (from 1005 components to deform components

such as QFP, BGA/CSP, SOP, connectors, and switches of 55 × 55 mm and

square components) packaged in tapes, stick, trays, etc.

Small and light DD (Direct Drive) motors are used for the placement heads

(called “DD heads” hereinafter), enabling the highly accurate θ correction. The

2-beam cooperative movement also made it possible to achieve the tact time of

approx. 0.46 seconds per component.
