Optical Nozzle Query

7.4.27 Optical Nozzle Query

▪ After the reference run, the gantries move into the wait position and performs the first nozzle

scanning. During the production, a nozzle scanning run is performed after 350 head cycles (can be

set by SIPLACE service if required) and after the completion of the board currently processed. This

ensures that the nozzle quality is continually checked during the production process:

– All nozzles listed in the scan parameters of the station database will be measured by the

component camera.

– If there is any deviation from the defined size, shape or brightness, the machine will show the

message: Nozzle worn down or contaminated.

▪ Tiny nozzles may touch the solder paste or the glue because of component shift and the minimum

component height.

▪ The number of components per segment (number of head cycles), after the next nozzle query has

been performed, should be adjusted to the customer's process requirements. This check is always

performed after completing PCB processing.

Air Blast Control During Placement

7.4.28 Air Blast Control During Placement

The air blast is controlled by the digital pressure control valve, which can be programmed via the

component shape data in the SIPLACE PRO computer. In the component shape data, values between

0 and 255 mbar can be set at "Advanced Handling". The standard value which is transmitted with the

component shape to the station is 150 mbar. This value needs to be reached to 80 % during placement.

Detailed component placement procedure: Z Axis Up

LB down switches:

▪...

▪ Pickup/placement position; air blast threshold "place

component" reached? Yes

▪ Start signal for upwards movement

Z axis starts:

▪ Z axis positioning upwards

Head firmware:

▪ Digital pressure control valve: switches air blast OFF

▪ Reset "light barrier down" signal

Axis controller:

▪ Z axis measurement value for nozzle "empty" and

▪ Z axis in safe area =

▪ Enable X, Y gantry axes.

Vacuum query:

▪ Vacuum threshold for holding circuit reached? Yes

▪ Star axis starts.
