Abstract

A process and a laminating device for producing a microfluidic device are proposed, wherein a film is pressed onto a carrier under the effect of heat and thereby attached to it. During the attachment the film is lifted by the blowing in of gas on the carrier side to prevent it adhering in a non-attachment region and is vented on the remote side. The device is compressed between a holder and a thermode of the laminating device during the lamination. An elastic intermediate layer is arranged in each case between the device and the holder and between the device and the thermode, for evening out the contact pressure and obtaining uniform attachment of the film to the carrier.
