To consider this issue three various LTCC (Low Temperature Co-fired Ceramics) based fluidic microsystems for light transmittance/absorbance measurements were designed and manufactured. The main distinction between these micro-devices was a way of fluidic inlet and outlet connection to the optical channel. Significant differences of output signal for each structure were noticed. To explain this phenomenon a CFD (Computational Fluid Dynamics) simulations were done.

The microdevice was made as separate module, which can be connected via tubing to any microanalytical system. The designed detector allowed to measure an optical absorbance (transmittance) in the analytical channel. Presented microfluidic detector can be

All experiments were performed at room temperature (25 oC) using four different lamination pressures (5, 10, 15 and 20 MPa). Two different alumina tapes developed by Swerea IVF were taken into account. The examined tapes contained different latex binder systems (LDM 7651S or Resicel E50). The quality of the laminated structures were analyzed before and after firing using optical microscopy. Moreover, the influence of the lamination pressure on the structures’ surface roughness was investigated using profile measurements gauge. The performed experiments have shown which combination of lamination pressure and type of latex binder is the best to obtain defect-free multilayer ceramic structures.
