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.

Method and

Reference Point

Position Correction Method: PEC Recognition

• By recognizing the fiducial marks using the PEC camera, positional

deviation covering the whole area of PCB and expansion of the printed

patterns on PCB can be corrected.

• To correct the positional deviation covering the whole area of PCB,

fiducial marks must be put on two or three places of PCB (2 fiducial

marks required for each unit PCB of a multi-unit PCB).

• To correct the positional deviation of component placement points, put

one to two fiducial marks on the PCB In this case, it is recommended that

two fiducial marks be located symmetrically such that the center of

gravity (the center of the fiducial marks) becomes the center of the

component placement point.

Note : The center of the mark is the reference point.

The reference point differs depending on the contents of the

specifications. Consult our sales personnel for details

Example :

To correct the positional deviation covering the whole area of PCB (PCB

Overall Correction)

To improve recognition accuracy, put fiducial marks diagonally on two places of

PCB when the 2-point recognition mode is selected. In the case of 3-point

recognition mode, put two fiducial marks diagonally and one fiducial mark close to

one of the remaining corners.

Example 1 :

To correct the positional deviation of component placement points

(1-point recognition)

Put a fiducial mark on the center of component placement point or

a desired point around the center.

Recommended Position: Center of Component Placement Point

•

This position is effective when the positional deviation covering the whole

area of PCB is corrected.

When the PCB overall correction operation is performed, the theta (angle)

correction is also made. The fiducial mark described here is used to correct

the placement position.

Example 2 :

To correct the component placement point

(2-point recognition)

Put fiducial marks on the desired two points around the center of

component placement point.

Recommended Position : Point Symmetry

It is recommended that two points (fiducial marks)

should be located symmetrically on both sides of the

center of the placement position.

(A-A'/B-B')

•

These fiducial marks are used to correct the component position and the

theta (angle).

The 2-point recognition is effectively to correct deviated and distorted part

of the printing patterns.
