Placement Heads

TwinHead for High-Precision IC Placement

Description

This sophisticated placement

head consists of two place-

ment heads of the same type

coupled together (twin

head). Both heads work

using the Pick & Place prin-

ciple. The TwinHead is suit-

able for processing

particularly difficult or large

components. Two compo-

nents are picked up by the

placement head, optically

centered on the way to the

placement position and ro-

tated into the necessary

placement angle. The com-

ponents are then placed

gently and accurately on the

board.

The placement head can also

use the nozzles for the Pick &

Place head (used on the F5

HM) in addition to the

nozzles recently developed

for the TwinHead.

Collect &Place head nozzles

can also be used.

Checking and self-learning

functions

The TwinHead's reliability

can be further increased with

various checking and self-

learning functions.

• For example, vacuum

checks at the nozzles indi-

cate whether the compo-

nent was picked up or

correctly.

• High-resolution, digital

component vision camer-

as such as the Fine-pitch

and Flip-chip vision camer-

as (optional) identify the

smallest deviations in the

component position. The

digital vision system cor-

rects such deviations, thus

guaranteeing a correct

placement position. The

digital component camer-

as are permanently fixed

to the machine frame.

• The component package

form is also checked and

the component is not

placed if the geometric

data thus determined dif-

fers from the programmed

data.

• A force sensor measures

and monitors the specified

component placement

forces.

Placement Heads

Nozzle Changers (Collect&Place Heads)

Description

Nozzle changers increase the

flexibility of placement heads

when processing different

components. The nozzle con-

figuration can be quickly

modified for new placement

jobs.

Exactly defined positions and

the perfect seating of the

nozzle in the garage guaran-

tee minimal radial eccentrici-

ty at the placement head.

Up to 4 nozzle changers can

be installed for the 6-nozzle

or 12-nozzle Collect & Place

heads (C&P6 or C&P12):

Location 1: 2 nozzle changers

(NC6 or NC12)
