HPCaP
High Precision Capillary Printing

A microscopic pen for large-scale ambitions

Hummink is the exclusive developer and supplier of HPCaP. A technology built for manufacturers who need precision, material flexibility, and throughput in one process.

  • No pressure
  • No satellite drops
  • No splashes
HPCaP and conventional additive processes compared: the micropen leaves one clean dot in the centre of the target, the print head drop splashes

BIRD module micropen printing on a wafer, under the microscope objective

A simpler process for micron-scale manufacturing

No mask required

No UV exposure during deposition

No chemical reaction during deposition

Design freedom: from simple lines to multi-layer structures

HPCaP maintains the same resolution across geometries. Designs can follow device performance requirements instead of manufacturing constraints.

Frequently asked questions

What makes HPCaP different from other printing technologies? 

Unlike droplet-based methods, HPCaP prints without satellite drops or splashes and adapts to uneven surfaces thanks to an integrated AFM with 5 nm Z-precision. It supports a wide range of inks and substrates while using very little ink. 

What is the printing resolution?

The printing resolution of HPCaP ranges from 80 µm to 600 nm.

What force is applied to deposit ink with HPCaP technology?

HPCaP deposits ink by capillary force only, through a meniscus formed between the tip and the substrate.

Which industries use HPCaP?

HPCaP addresses applications in semiconductors and advanced packaging, display and display repair, printed electronics and biosensors, MEMS, watchmaking, aerospace, defence, and advanced R&D.
