摘要:
Fabrication method of microfluidic devices consisting of a sheet (1) which is 200 micrometre thick or less and a rigid part (3), both made of thermoplastic polymeric material comprising: - degasification of: ○ a polymeric sheet of thermoplastic material (1) ○ an auxiliary rigid part (2) ○ a polymeric rigid part of thermoplastic material (3),
- bonding through a temporary bonding procedure, of the degassed thermoplastic polymeric sheet (1) to a degassed auxiliary rigid part (2), producing an sheet-auxiliary part set (4), - bonding through a permanent bonding procedure, of the thermoplastic polymeric sheet (1) of the sheet-auxiliary part set (4) obtained in the previous temporary bonding stage, to the thermoplastic polymeric rigid part (3) which was initially degassed, - detaching the auxiliary rigid part (2) of the thermoplastic polymeric sheet (1) permanently bonded to the thermoplastic rigid part (3), to produce a final part which is completely polymeric (5).
