A method for local application of thin organic adhesive films on micropatterned structures

Study peeling strength of tape carrier packaging and chip scale packaging

“…After 24 h cooling at room temperature, the denture base sample is bonded to 800-grit wet/dry abrasive paper. A polyethylene mould is used to define the area over which the soft lining material was attached to the base [5][6][7][8].…”

<title>Novel bonding method for polymer-based microfluidic platforms</title>

“…When using the adhesive bonding method, care needs to be taken in order to prevent the adhesive from flowing into the micro channels. Other techniques such as adhesive tape bonding (lamination), thermal (IR, hot-plate, laser) bonding, ultrasonic welding, and solvent bonding (i.e., partially dissolve the bonding surfaces, and evaporate the solvent) have also been tried [1][2][3][5][6][7][8][9][10]. Lum and Greenstein [6] prepared microdepressions on one substrate and microprojections on the other so that the substrates can be mated together to secure the relative position.…”

“…A layer of monomer or pre-polymer was deposited on the microprojections before being mated and further polymerized to provide a bonding effect. Dreuth and Heiden [8] applied a thin adhesive film on a substrate and the adhesive was then transferred to the elevated microstructures by stamp printing. Glasgow et al [9] introduced a solvent bonding technique in which a layer of polyimide precursor and solvent with dissolved precursor was placed in contact with patterned structures made of uncured polyimide precursor.…”

Nanoscale Polymer Fabrication for Biomedical Applications

“…Several techniques such as lamination (adhesive tape, thermal adhesive film), thermal (IR, hot-plate, laser) bonding, ultrasonic welding, and solvent bonding (i.e., partially dissolving the bonding surfaces, and evaporating the solvent) have been tried [2,20,33,[163][164][165][166][167][168][169] on polymer-based microdevices. McCormick et al [170] successfully applied a thermal activated adhesive (Top flight MonoKote, Great Plane Model Distributors, Champaign, IL) to bond a Mylar sheet with an injection-molded acrylic microchip for DNA separations.…”

“…Rossier et al [166] used a 5-µm thick polyethylene adhesive layer to seal a UV laser photo-ablated PET microchannels with a PET film for electrophoretic separations. Dreuth and Heiden [167] applied a thin adhesive film on a substrate and the adhesive was then transferred to the elevated microstructures by stamp printing. Lamination by adhesive tapes or thermal adhesive films is probably the simplest and fastest method, but carries the risk of creating channels with different top and bottom surfaces.…”
