1. A microfluidic apparatus, comprising:
a PCB (printed circuit board);
a biological chip overlying and attached on the PCB;
a microfluidic housing overlying and attached on the biological chip and attached on the PCB, the microfluidic housing having a first cavity, an inlet into the first cavity, an outlet out of the first cavity, and an inner sidewall extending downwardly from a main body of the microfluidic housing adjacent to and bounding the first cavity, the inner sidewall being attached to the biological chip using a first adhesive layer to form a flow cell with the first cavity extending along an upper surface of the biological chip, the microfluidic housing having an outer sidewall extending downwardly from the main body of the microfluidic housing and attached to the PCB using a second adhesive layer;
wherein:
a distance between a bottom surface of the outer sidewall and the PCB is greater than a distance between a bottom surface of the inner sidewall and the biological chip;
the second adhesive layer is thicker than the first adhesive layer;
the first adhesive layer comprises a first adhesive material; and
the second adhesive layer comprises a second adhesive material.
