Flat Tips

Die-Attach---Flat-Tip-1 Die-Attach---Flat-Tip-2 Die-Attach---Flat-Tip-3 Die-Attach---Flat-Tip-4


Rubber Flat Tip designs are versatile rubber tips that are suitable for a wide range of applications. Flat Tip designs feature a single vacuum hole and a flat contact surface controlled to stringent flatness tolerances.

Oricus manufactures an extensive range of standard Rubber Flat Tip sizes with central and offset vacuum hole configurations in various sizes. Customized Flat Tip designs with micro thin walls (≥0.05mm wall thickness) can also be produced for special applications.


  • Direct contact to the face of the die or device
  • Suitable for use with our Common, Tri-Lock, Compression and Magnetic Holders
  • Available in NBR, HPR, UPR and CR Rubber Materials
  • 50-90 Shore A Hardness levels to cater to a wide range of different applications
  • E6-E9 Static Dissipative properties to ensure proper Electrostatic Discharge
  • Can be made in Round, Square, Rectangular and Custom outer profiles


  • Cost effective solution that offers superior Cost-Per-Part
  • Universal design that is suitable for a wide range of dies sizes and thicknesses
  • Offers structural support to the die or device, allowing for minimal flex to during the Pick and Place process.
  • Flat surface allows for uniform bond force to be applied throughout the tip face, reducing the probability of voids in the adhesive or DAF
  • Pick-and-Place impact and bond forces are absorbed by the soft and accommodating nature of our Rubber Flat Tips to ensure that the die or device is not damaged in any way

Material Information

All our rubber compounds are entirely developed in-house by our Material Science R&D team. These compounds are developed with the latest innovations in rubber technology and feature formulations that are designed specially for use in the Semiconductor industry. Extra pure formulations that leave no marks on die, wide range of Shore A hardnesses, Static Dissipative properties, long tool life and full RoHS & REACH compliance are the hallmarks of our rubber compounds.
