2.8 Featchers to Achieve high Accuracy with the TX micron
Measurement scales of main axis are glass scales with very low coefficient of thermal expansion
(CTE) instead of metal scales.

2.8 Featchers to Achieve high Accuracy with the TX micron
26 Technical Training FSE SIPLACE TX-Series 01/2018
●
Higher resolution of linear scales for main axes
●
Reference glass bars (with very low coefficient of thermal expansion (CTE))
●
Double resolution of star axis encoder in CP20M2 head compared to CP20 P head
●
Added calibration and recalibration routines
Accuracy of 15µm @ 3σ
●
Enhanced & stiffer conveyor system
●
Vacuum tooling made of material with low coefficient of thermal expansion and additional
●
Reference glass bars at the vacuum tooling
Accuracy of 20 µm @ 3σ
To achieve an even higher accuracy than the 25 µm @ 3σ with the CP20M2 head the high preci-
sion flag (HPF) is available at SIPLACE TX micron.
The HPF can be activated in SIPLACE PRO per component shape.
Note: Today there is no possibility to set the high precision flag per placement position.
Every component for which the HPF is activated will be placed with an accuracy of 20 µm @ 3σ us-
ing the HPF will have impact the placement speed.
The speed reduction depends on the amount of components with HPF and available heads in line.
Accuracy of 15 µm @ 3σ for TX 2i micron 15
To achieve the accuracy of 15 µm @ 3σ following preconditions are required:
●
SIPLACE TX2i micron 15
●
Special vacuum tooling with high accuracy glass bars in the front and rear of the substrate
●
High precision flag set for 15µm for the components shapes required
Note: A SIPLACE TX2i micron cannot be upgraded to a SIPLACE TX2i micron15.
Customer specific vacuum tooling’s for TX 2i micron 15
In order to run the TX micron 15 a customer specific vacuum tooling is required.
Therefore 3 different vacuum tooling bases for different PCB size are available.
The top plate of the vacuum tooling can be exchanged and is product specific.
Therefore when ordering a vacuum tooling for the TX micron a product specific – tooling plate
needs to be designed and manufactured. Therefore the exact dimension (X,Y,Z) of the PCB is re-
quired. Best is to have the drawing and if possible a sample board in order to design the board.
The according items are:
●
Vacuumtooling SIPLACE TX 100mm width
●
Vacuumtooling SIPLACE TX micron 55 mm <= 67 mm.
●
Vacuumtooling SIPLACE TX micron 68 to 100mm
