20 Segment Collect&Place CA

Head for Very High Speed Placement

Description

The 20 segment Collect&

-Place head operates ac-

cording to the Collect&Place

principle i.e. twenty compo-

nents are picked up from the

placement head within a sin-

gle cycle, are optically cen-

tered on the way to the board

and are also rotated into the

required placement position.

Lastly, the component is set

down gently and accurately

on the board.

The 20 segment -Col-

lect&Place head enables you

to significantly increase the

performance of the place-

ment head and the whole

placement machine. With the

help of high-resolution com-

ponent cameras, the 20 seg-

ment Collect&Place head

can optically center and

place components of size

01005, up to 6 mm x 6 mm.

Checking and self-learning

functions

Various control and self-

learning functions enhance

the reliability of the Col-

lect&Place head.

• To increase placement ac-

curacy, the 20 segment

Collect&Place head fea-

tures a component sen-

sor. At the pickup and

placement position, it

checks that the compo-

nent is present at the noz-

zle. The sensor only

supports components up

to a thickness of 90µm.

• The digital component

camera on the placement

head determines the

package form and the pre-

cise position of each com-

ponent at the nozzle.

Deviations from the pickup

position are corrected be-

fore placement.

• A sensor registers the rel-

ative movement between

the nozzle and the seg-

ment when components

are placed and sends a

signal to the position con-

trol axes.

With this sensor stop

method, differences in

height during pickup and

any unevenness of the

PCB surface are compen-

sated during placement.

12 Segment Collect&Place CA

Head for Very High Speed Placement

Description

The 12 segment Collect&

Place head operates accord-

ing to the Collect&Place prin-

ciple i.e. twelve components

are picked up from the place-

ment head within a single cy-

cle, are optically centered on

the way to the board and are

also rotated into the required

placement position. Lastly,

the air kiss sets down the

component gently and accu-

rately on the board.

Checking and self-learning

functions

Various control and self-

learning functions enhance

the reliability of the Col-

lect&Place head.

• For example, vacuum

checks at the nozzles indi-

cate whether the compo-

nent (CO) was picked up

or set down correctly.

• A digital component cam-

era on the placement head

determines the precise

position of each compo-

nent at the nozzle.

• Deviations from the pickup

position are corrected be-

fore placement.

• The package form is also

checked and the compo-

nent is not placed if the

geometric data thus deter-

mined differs from the pro-

grammed data.

The vertical axis for picking

up and placing the compo-

nent works in sensor stop

mode, This sensor stop

method compensates differ-

ences in height during pickup

and any unevenness of the

PCB surface during place-

ment. In addition to the vacu-

um check, an optional com-

ponent sensor can be used

to check the component

presence at the nozzle.

The use of a component sen-

sor is recommended in par-

ticular for placement with

small components, such as

0201.

The 12 segment Collect&

Place head is fitted with a

high-resolution component

camera as a default. With the

help of this camera, the 12

segment Collect&Place head

can optically center and

place components of size

0201, up to

18.7

mm x18.7mm

(SWS: 0.8 mm x 0.8 mm up

to 12 mm x 12 mm, larger

dies on request.
