Description

Linear vibratory feeders pro-

cess components in stick

magazines. These can be

easily configured with the X

adapter for use with the X

component trolley. They can

be refilled without stopping

the machine. The X adapter

also allows you to set up the

label presenter and the

reject conveyor on the X

component trolley. The LDU

X is suitable for dip fluxing of

flip chips, CSP (Chip Scale/

Size Packages) and for coat-

ing flip chip bumps with iso-

tropic conductive adhesive.

The SIPLACE Glue Feeder

allows you to position dots of

adhesive on a component,

before it is placed.

Danger

To ensure that your SIPLACE placement machine runs safely, a feeder must be assigned to

every location on the component trolley.

If you do not have enough feeder modules, then you should use dummy feeder modules as

space holders.

Dummy feeder module for the component trolley of the X series (CA series)

The dummy feeder module for the SIPLACE X series occupies one track on the component

trolley.

Vision Sensor Technology

PCB Position Recognition

Description

Different fiducial shapes

prove to be optimal depend-

ing on the condition of the

surface. When using bare

copper surfaces with low oxi-

dation, it is advisable to take

the single cross, as the high

amount of information pro-

vided helps achieve the

greatest accuracy. Rectan-

gle, square and circle are

less "informative" but save

space and can even be used

when oxidation is at an

advanced stage. Circle or

square are advisable for tin-

plated structures as the ratio

of the fiducial dimensions to

the presolder thickness is

particularly favorable.

Fiducial criteria
