Application Example Underfill

The Adhesives Dosing System for Conductive Adhesives

So-called Underfill material applications are used for dosing conductive adhesives. The isotropic conductive adhesive is the electrical connection between microchip and substrate. The adhesive is then cured with thermal or UV radiation. Finally, the resulting cavity is filled. This process is called “underfill“.


preeflow<sup>®</sup> impresses XENON

Consistently high quality and extremely precise dosing: characteristics that are part of the daily operation at XENON Automatisierungstechnik GmbH. Thanks to the use of precision dosing systems, the company makes applications to a wide variety of components, sometimes under pressure. It was therefore natural that XENON wanted to maintain this level during dosing.

Underfill application - application of conductive adhesive - with preeflow dispensers in fully automatic dosing system from Xenon

Choosing the right dispenser was not difficult for XENON: the required dosing volume range, the uncomplicated implementation and the precise accuracy of the preeflow dispensers quickly impressed the company. The fully automatic dosing system offers precision and reliability. And is therefore the perfect partner for XENON.


preeflow Underfill advantages:

  • Precise dosing
  • Complete control of the dosing process
  • High repeatability
“The spindle dosing system is controlled directly via the plug´n´dose box and the SPS, so that the volume flow can be easily adjusted to the processing path.”XENON Automatisierungstechnik GmbH
