Assembly and interfacing

Assebled sideconnect chip with connected tubes

Assembly of Point-of-Care, diagnostic and medical devices

As a lab-on-a-chip solution provider we offer a wide variety of services to assemble microfluidic and MEMS components into a customised Point-of-Care, diagnostic or medical device. Assembly is executed in our cleanroom facilities using ISO 9001 and ISO 13485 standards. Quality and traceability of all assembled components are secured in our quality management system. Identification (e.g. barcoding), packaging and labelling of assembled products can be done according to customer needs.
Besides customised assembly tooling, we apply several common industrial technologies such as:

  • Flip-chip bonding and underfilling (e.g. for integration of various types of sensors)
  • Dispensing of liquid adhesives (e.g. optical, thermally or electrically conductive)
  • PSA tape cutting and aligned bonding
  • UV and thermal curing
  • Surface functionalisation (e.g. PECVD coatings)
  • Spotting of biological content
  • Plasma activation
  • Laser marking (e.g. barcoding)

With these available technologies we can assemble various materials such as thermoplastic polymers, elastomers, resins, glass, silicon, metals or any combination of these (e.g. hybrids).
We are collaborating with several industrial partners that are specialised in the design and manufacturing of (semi-) automated assembly equipment. This enables flexible and efficient scaling from low volume prototyping to medium and high volume production.

Lab-on-a-chip interfacing

Micronit specialises in more than microfluidic chips only, looking at interfacing with the equipment and hardware around the microfluidic devices. Fluidic connections and connectors located between the microfluidic device and a fluidic tube or capillary are of high importance. Next to fluidic connections many types of electrical connections are often required. It can be direct sensor integration or interfacing between a sensor PCB and electrode contact on the microfluidic device.

Micronit aims at providing more standardised interfacing solutions to the microfluidics world. Fluidic connections should be compatible with different suppliers of microfluidic devices. Connections should also comply with interfacing of e.g. pumps, sensors and valves. In many cases adapting to standards like microscope slides and SBS microtiterplate formats are possible. For other device sizes or formats Micronit provides standard interfacing solutions off-the-shelf. Connection types can be selected based on operating conditions such as pressure, temperature, reusability.

Available interfacing platforms

  • Fluidic Connect platform
    • Fluidic Connect Pro
    • Fluidic Connect 4515
  • Sideconnect platform
    • In-line solutions
    • Cartridge assemblies

We can realise a range of interfacing types:

  • Single ferrule interfacing in the Fluidic Connect Pro or Sideconnect
  • Nut and ferrule assemblies to connect via threaded ports
  • Adhesive interfacing (using liquid adhesives or tapes)
  • Electrical contacts (using spring loaded probes in several configurations)
