UNIVERSAL CONTACT – PICK & PLACE APPLICATION
Description:
Application recommendations for pick and place of Universal Contact product range
using production SMT equipment.
SCOPE:
The scope of this application note is to advise about equipment set up and nozzle selection
when pick and placing ITT’s Universal Contact products using production SMT equipment
onto Electronic PCB’s. This note will also detail information about the normal status of
components when packaged in tape and reel packaging materials.
PRODUCT RANGE DETAILS:
The Universal Contact range consists of eight contact sizes covering a connection height
range of 0.8mm to 4.0mm.

COMPONENT ORIENTATION IN THE TAPE POCKET:
The Universal Contact is maintained in position by a rectangular shaped pocket in the tape.
This pocket shape controls the orientation of the contact so it is always pointing in the correct
direction, with the contact point nearest the tape sprocket holes and the pick and place
surface uppermost.
Example of tape design for 120220-0161:
The Universal Contact has a very low mass and due to this it can not be guaranteed that the
component will sit fully flat in the base of the pocket when viewed in the tape. However,
during the feeding and indexing of the machine, the natural vibration should settle the
component down into the pocket. Should the vibration not re-position the contact fully the use
of the correct nozzles and settings during pick and place will rectify this situation.
Care needs to be taken during the pick and place process to control shock and vibration from
the machine. Excess shock and vibration once the cover tape is removed can cause the
component to jump in the tape into an incorrect orientation.
For more detail on nozzle selection and pick and place settings see pages 4 to 7.

COMPONENT POSITION IN THE POCKET
1) Ideal position of the component in the tape pocket. The contact is sitting flat in the bottom
of the pocket, centrally positioned and not tipping over to either side. The contact can move
in the ‘X’ and ‘Y’ direction a little.
2) Possible out of position situation for the contact in the pocket. This can not be controlled or
avoided but it can be dealt with during pick and place to enable the contact to be pick and
place. The component will usually vibrate down into the pocket once the cover tape is
removed and the feeder indexes. Providing the correct nozzle type is used and the correct
offset position, the nozzle can be used to nudge the contact down into the pocket

3) The contact can tip from side to side inside the pocket. This is unavoidable and will be
corrected as the nozzle comes down to pick up the contacts from the pocket
NOZZLE SELECTION AND PICK AND PLACE AREA
The pick and place area on each contact size varies due to the contact size. Care needs to
be taken to select a suitable nozzle based on the size of the pick and place area and the
shape of the beam.
Recommended Nozzle Sizes
For pick and placing universal contacts, it is recommended to use a cylindrical, tube type
nozzle and to maximise the internal diameter and cross sectional area of the vacuum area.
The nozzle recommended nozzle sizes for each contact are as follows:

Recommended nozzle offsets
Each contact is a different size and therefore requires a different nozzle offset in ‘X’ and ‘Z’. It
is recommended to run a trial to find the best offset in ‘X’ and ‘Z’ for the particular type of
SMT machine being used as this will differ with regard to pick and place speed, feeder type
and accuracy.

It is recommended that when picking the contact from the tape pocket, the nozzle should
NOT touch the contact. There should be a small gap left between the nozzle and the pick
and place area and allow the vacuum force to pick the contact from the pocket.
Care should be taken when placing the contact to ensure excessive force is not applied to
the contact beam by the nozzle. This could damage the contact. Maximum force which can
be applied to the contact on placement is 1.5N MAXIMUM

These recommendations should be used to set up the SMT pick and place offsets. The
offsets will require fine tuning for each machine type and speed of operation in order to gain
maximum pick and place performance.

The offsets should be carefully controlled to avoid problems with dropping or damaging parts.
If force is applied to the contact during pick up, the beam could be compressed. When the
machine indexes to move the part away, the force will be removed and the component will
spring away and cause a drop failure. An air gap should be maintained and allow the vacuum
force to pick the contact from the pocket. The ‘Z’ offset can be adjusted to suit nozzle size
and vacuum force to achieve this.
Offset in the ‘X’ direction should be carefully controlled to ensure good pick and place and
avoid damage to the contact.
If the maximum offset in ‘X’ is exceeded the nozzle could miss the pick and place area at the
end of the beam where it bends away to the solder pad. This will reduce the vacuum power
and cause a pick and place failure. See following picture:
If minimum offset in ‘X’ is exceeded, there could be damage to the contact pre-load tag

If the contact is in a misplaced position as detailed on ‘page 3’, the nozzle should touch the
beam during its travel down into the pocket and seat the contact down into the pocket.
Once the cover tape is removed from the pocket, if the vibration and shock of the feeding
mechanism on the machine is too violent, the contacts could jump out of position in the tape,
or even jump out of the pocket due to their low mass.
This situation can be controlled in the pick and place process by ensuring the shock of the
tape indexing is not too violent.
