4.1 Placement of Snap-In Components

50 Bedienungsanleitung OSC Package User Guide OSC-Paket - 06/2017

After the first board has been completely produced, it will be transferred to the output section or the

configured inspection station and marked for manual inspection. The operator has to inspect every

snap-in placement position and confirm whether the placement is correct or not. If correct, the cor-

responding Z-axis position will be stored as reference position and used as placement position for

all subsequent boards. If not correct or if subsequent boards are already produced before the

height reference values have been taught, the measured height will be ignored and the operator

has to confirm the height whenever the next component is placed.

The height reference values are not uploaded to SIPLACE Pro. Thus, when the job is changed at

the placement machine or the machine is shut down, the height reference values have to be taught

again.

NOTICE

Using SIPLACE Smart Pin Support

For reliable snap-in detection it is recommended to set support pins close to the snap-in

placement positions. Detailed information on Smart Pin Support can be found in the

SIPLACE Smart Pin Support Operation and Configuration User Manual, item no.

4.1.1 Procedure

The following overview lists the single work steps that have to be performed in the specified order

to place snap-in components.

4.1 Placement of Snap-In Components

4.1.2 Application Example

Step 1: SIPLACE Pro

► In the Station Editor under Placement Station,

enable the OSC Package option under Installed

options.

Step 2: SIPLACE Pro

► In the Component Shape Editor, select the Snap

In feature as placement process for the

component shape.

Step 3 and Step 4: SIPLACE Pro

► In the Handling tab, enable the Snap In

Z-threshold option in the Placement group for the

component shape.

► Define a Z-threshold value in mm.

The threshold value must be > 0.

Default value: 0.500 mm

The first board has to be inspected and confirmed as described in Step 5 and Step 6 below. After

this, the machine uses the Z-threshold value to determine whether the snap-in component is com-

pletely locked in the subsequent boards or not.

Setting Z-threshold value

The Z-threshold value is used to evaluate whether the snap-in component is locked or not. The

current Z-axis position of every snap-in placement will be compared with its corresponding height

reference position. If the difference between the two values is <= the set Z-threshold value in

SIPLACE Pro, the snap-in component is considered to be locked. If the difference is greater, the

snap-in component is considered not to be locked and an error message is displayed.

If the Z-value is too large, the machine can not detect an erroneous locking. If the Z-threshold value

is too small, the machine may stop often.

Depending on the component, you can start with the default value of 0.500 mm for the Z-threshold

and change this value successively in small steps.
