4.3 New Features and Changes with R19-1

In this chapter all features are listed that have either been newly introduced or have been updated

with R19‑1.

4.3.1 Placement of Exceptionally High Components

From R19-1, there has been an update to the placement of exceptionally high components feature

introduced in R18-2 (please refer to 4.2.6 "Placement of An Exceptionally High Component" [}76]).

Besides the TwinVHF placement head, it is now possible to place exceptionally high components

with a CPP placement head as well. In both cases the software provides automatic crash avoid-

ance and the gantry and the placement head are moved around the exceptionally high components

that are being placed. Furthermore, the placement sequence has been optimized so that more than

one exceptionally high component can be placed with the Twin VHF placement head.

WARNING

Description of the component height

It is essential that the description of the component height in SIPLACE Pro is correct.

Otherwise, the hardware (machine, board camera etc.) could be damaged.

The described component height is used in the station software to decide whether the

placement head and the board camera are allowed to be moved over an already placed

component. If this is not possible without collision, they are moved around this component.

Prerequisites

The prerequisites for the Twin VHF and the CPP placement head differ in the following details:

Prerequisites Twin VHF CPP

Maximum component height 46mm without centering pins

50mm with centering pins

(46mm body height + 4mm

centering pin height)

15.5mm

Placement head Twin VHF placement head, as

the only placement head in the

station or in combination with

either another Twin VHF or a

CPP mounted in high position

CPP placement head mounted

in high position on last place-

ment area of the line

No TwinHead or Twin VHF

placement head must be used

in the same placement area.

Placement machine SIPLACE SX V2 No restrictions

Conveyor Single conveyor No restrictions

The following prerequisites apply to both placement heads:

●

Exceptionally high components are placed in the last station of the line.

●

The minimum horizontal safety distance for moving components around other already placed

components is 5mm.

●

The highest of the previously placed components defines the minimum flying altitude for all

components placed by the last station.

CAUTION

Set behavior for machine stop to "Cycle Stop"

When placing high components, it is recommended to set the behavior for a manual

machine stop to "Cycle Stop". This can be done in the Line Control GUI under Manual Op-

erations > Entire Machine > Hardware stop button behavior. By doing so, after the stop

button is pressed, the placement cycle is continued for a specific time to complete the

placement cycle before the machine stops and the cover lock is released. This way, when

the user moves the gantry while the cover is open, collisions of high components still on the

placement head with already placed components can be avoided. The behavior is active

even after the machine is restarted.

In some cases it is possible that the placement cycle is not finished after the stop button is

pressed. In these instances it is possible that components are still at the placement head

which can collide with other already placed components if the user moves the gantry while

the cover is open.

CAUTION

Risk of collisions when manually moving the gantry

When the user moves the gantry of the CPP placement head while the machine is stopped,

there is a collision risk when moving the CPP placement head over already placed high

components, e.g. components placed by a Twin VHF placement head.

4.3.2 Component Chipping Inspection

The component chipping inspection functionality checks whether the edge of a component has lar-

ger deviations than defined, which might indicate that the edges of a component have been

chipped off. The chipping inspection is an additional measurement step and takes places after

position measurement.

There are two ways to activate the component chipping inspection:

Activation via SIPLACE Pro

► In the Vision Inspection tab of the Component

Shape Editor, activate the Chipping inspection

checkbox.

Activation via SIPLACE Vision

► In SIPLACE Vision, change the value of the Chip-

ping inspection option to Yes.

In order to exactly determine if a component has chipped edges, the measurement for the chipping

inspection can be further fine-tuned in SIPLACE Vision, e.g. the tolerances used can be changed,

or the illumination can be adjusted.

If it was determined that a component has chipped edges, the component will be rejected.

Restrictions

●

Only supported for component shapes of type BareDie, BGA, CCGA, Chip, Moulded, and

Nonstandard.

4.4.1

Placement of Snap-in Components – Improved Teaching

With R19-1, there has been an update for the placement of snap-in components feature introduced

in R16-2 (please refer to 4.1.1 "Placement of Snap-In Components" [}53]) and to the improved

teaching procedure introduced in R18-2 (please refer to 4.2.1 "Placement of Snap-in Components –

Improved Teaching" [}70]).

Up to R18-2, the height reference values were not uploaded to SIPLACE Pro and had to be taught

again when the job was changed at the placement machine or the machine was shut down. From

R19-1 they are stored locally on the machine and do not need to be taught again.

New Features and Changes with R19-2

In this chapter all features are listed that have either been newly introduced or have been updated

with R19‑2.

Placement of Heavy Components with TwinHead Placement Heads

For R19-2, the maximum component weight that can be placed has increased.

SIPLACE Pro Settings:

To place components with a weight of more than 100g, reduced accelerations must be used.

Up to R19-2, the accelerations could be reduced to 100%, 75%, 50%, 25% and 10% in SIPLACE

Pro. With R19-2, additional reductions to 5%, 4%, 3%, 2%, and 1% are available for components

heavier than 100g.

Station:

Components with a weight of up to 160 g can be placed by all TwinHead variants. Components

with a weight between 160g and 240g can only be placed with a Twin VHF. Additionally, a new

nozzle adapter for Twin VHF, item no. [03149670-xx] has been introduced. With this new nozzle

adapter higher accelerations are possible. To determine the highest possible acceleration for heavy

components, the acceleration test (see4.1.5 "Finding Best Acceleration" [}66]) can be used.
