Problems solved by technology

The two main disadvantages of this approach are poor control of the channel height due to component and glue thickness deviations; and thermal loads on the inner channel surfaces that may disrupt some of the (bio)chemical processing required for the device to work
There is also the possibility of extrusion of glue into microchannels, or localized voids due to poor process control

Embodiment Construction

[0028] Microfluidic devices are of great interest in many fields, from electronic cooling to biosensors. Typically, the microchannels of the device are fabricated by forming trenches in a substrate (such as silicon, glass or plastic) and covering the structured substrate with a flat cover plate. For tiny channels, it is crucial to have high channel precision (because the flow resistance is proportional to the fourth power of the channel height), and the channel precision is determined not only by the structuring of the substrate, but also by the structure of the lid. combined process decision.

[0029] Basically, the bonding can be done using a variety of techniques, either direct bonding, where the lid and substrate are bonded directly, or indirect bonding, where an additional "glue" layer is used to achieve the bond. Direct techniques are limited in possible material combinations. In order to obtain a low-cost device, the substrate is usually made of plastic.

Abstract

The invention relates to a miniaturized fluid container with microchannels (11, 12) which are bordered by ridges (13, 14), wherein the crests of the ridges (13, 14) are glued to a cover plate (20). Additional stability may be achieved by distributing glue (33) in cavities between the microchannels (11, 12), the spreading of said glue being driven by capillary forces.

Description

technical field [0001] The present invention relates to a miniaturized fluid container with microchannels consisting of a structured plate and a cover plate and a method for manufacturing such a container. Background technique [0002] Miniaturized fluid containers are used in an increasing number of tasks, especially in the analysis of pharmaceutical, chemical or biochemical samples. A typical way of producing such containers is to etch the desired structures, eg microchannels, into a plate and place the structured plate together with a flat cover plate. [0003] Such a method is described, for example, in WO 01 / 54810 A1, where the cover sheet is coated with a thermoglue which is allowed to cure after the cover sheet and structured panel have been brought together. Two major disadvantages of this approach are poor control of channel height due to component and glue thickness deviations; and thermal loads on inner channel surfaces that may disrupt certain (bio)chemical trea...
