2. Overview

This function measures pick height properly by checking vacuum level at moving the head to

the tape guide of a feeder.

To determine pick height, it used to be necessary to measure the tape thickness by caliper,

and to adjust the height considering pick up rate. With this function, pick height is

automatically measured properly, so that you don’t need to create height data before the first

use of the machine.

2.1 Target

1. Supported feeder types are “4mm feeder” and “8mm feeder”.

Feeder parts of 12mm or wider, and tray parts are not supported.

2. Supported feeder guide types are iron and carbon.

Therefore, when one machine has both of above types of tape guides, guide

recognition is necessary to distinguish iron and carbon.

3. Supported nozzle types are as follows.

3. Function Details

This function measures the height of a head above the target tape guide, and calculates its

appropriate pick height. The result can be applied to board data. Therefore, you don’t need

any special equipment such as a laser measuring instrument to measure the pick height.

A head moves down to the feeder tape guide, and the height is calculated based on its

vacuum level. The result is translated to pick height and displayed on the screen.

It is possible to apply the measured pick height to board data, and to use it in production.

There are two types of tape guide, iron and carbon. They have different measurement

positions, so that it is necessary to recognize a tape guide by the moving camera. However,

if you use only either type of tape guide feeders, you can skip the guide recognition. To

recognize a guide, the special mark data is necessary. For more details, please refer to

Chapter 4 or 6.

Teaching head is supposed to pick the first one of the target feeder parts. If the first head

can’t measure the height, the second head does. If no head can measure the height, a

measurement error occurs.

In V4.50STD_R1.000 or later, it is possible to measure the height without mount data as

long as fixed board data is read. In this case, mounting heads and nozzles are automatically

determined. Please note that the determined combination of heads and nozzles will be

different from that you want to set.
