7.6.2 Type of illumination

The following types of illumination can be selected on the multicolor PCB camera:

– Standard lighting

This mixture of white and infrared lighting can be used to detect a broad range of fiducials.

The image contrast can be improved by varying the illumination, thus optimizing the centering

of different fiducials.

– White lighting

This type of illumination is used for standard PCBs with tinned fiducials.

– Blue oblique lighting

In most cases, this can be used to greatly improve the contrast with bright fiducials on a light

base material, such as ceramic or CEM. Fiducials covered with solder resist can also be de-

tected better on a light background.

– Infrared lighting

This type of illumination is particularly useful for fiducials that are covered with solder resist

or for fiducials on flex materials. It is also sometimes possible to improve detection of silver/

platinum fiducials on ceramic. This should be tested by carrying out a test centering or place-

ment run.

7.7 SIPLACE High-Force Head

Item no. 00119634-xx High-Force Head for the HF series (rather than a TwinHead)

This item number only applies when a new placement machines is ordered with a High-Force

Head rather than a standard TwinHead. 7

Item no. 00119753-xx High-Force upgrade kit

Use this item number if you want to replace a standard TwinHead with a High-Force Head.7

Item no. 00119654-xx High-Force Head reconfiguration kit

Use this item number if you want to replace a Collect&Place head with a High-Force Head.7

7.7.1 General

The SIPLACE High-Force Head is a development offshoot of the standard TwinHead. It can pro-

cess the same component range and also offers the possibility of achieving set-down forces up to

30 N.

Otherwise the technical data for the TwinHead and High-Force Head is the same (see section

3.7.4.3

, page 131).

All the nozzles and grippers that are used with the standard TwinHead can be used for the SI-

PLACE High-Force Head.

Programmable set-down force 1 N to 1.8 N ± 0.18 N

1.8 N to 10 N ± 10 %

greater than 10 N up to 30 N ± 15 %

7.8 PCB alignment

Item no. 00119677-xx PCB alignment for single conveyor

Item no. 00119678-xx PCB alignment for dual conveyor

7.8.1 General

PCBs to be processed sometimes have a length to width ratio of 1:2 or worse. This means that

the shorter side of the PCB points in the direction of travel. During travel, such PCBs may twist

slightly and, as a result, the fiducials no longer lie within the PCB vision camera's search window.

In this case, the "PCB alignment" option ensures that these PCBs are realigned precisely at the

stopping position.

If PCBs with recesses in the direction of travel are processed, this may result in different process-

ing positions on machines with mechanical stoppers (HS-50, S-25 HM, F5 HM) and on machines

that monitor this position with laser light barriers (HF, HS-60, S-27 HM). The "PCB alignment" op-

tion ensures that the PCBs are stopped at the same position on all PCB conveyors. The "PCB

alignment" option is available for both single and dual conveyors.
