Microfluidics Chip
Customer Demand
- Customer Background: Medical devices design and development industry, with a team of 80+ specialist designers and engineers for 37 years, winning over 260+ local and international awards for design and engineering excellence.
- Scene Description: Laminate overlay on aluminum and final combines the PCB for operation guidance.
- Demand portrait: The client currently designing a microfluidics chip (~50x19mm) which has 6 individual circuits, each with an input port, measurement/reaction chamber and an air relief outlet.
- Prototype chip: Which comprises of two PMMA pieces and a glass cover slip over each of the measurement chambers. Once have tested the prototype and verified the design, looking to engage us to produce mass production to cover R&D testing in Q3 2024.
- Mass Productionorder: Looking to replace the six individual cover slips shown below with something else that replicates the properties of the coverslip (rigid, optically clear, thin) but is easier to mass produce. This could be a single glass coverslip that covers all 6 chambers or another suitable material.
