In this paper, we present a new method that is capable of manufacturing microfluidic chips of polymethyl methacrylate (PMMA) rapidly and cheaply. This technique, which we call Tape adhering-Laser Cutting and Sealing Integration (TLCSI), only utilizes a CO2 laser and a piece of double-sided tape to produce a microfluidic chip in several minutes. It only has three main steps. First, the double-sided tape sticks to the surface of a PMMA substrate. Second, the microchannel should be cut on the surface of the double-sided tape. At last, a PMMA cover plate with liquid pools is pressed onto the surface of the double-sided tape and a CO2 laser is used to cut edges of the chip for sealing the chip. We present a qualified microfluidic chip with regular microchannels and sealing strength of 1.2[Formula: see text]Mpa. Compared with most current fabrication methods, TLCSI is a quick and cost-effective way to produce microfluidic chips of PMMA.

Laser sources are used in a large variety of applications for material processing. It is mainly used for welding, cutting, drilling, laser annealing, etc. This study narrows the scope down to one of the process, namely, laser drilling.The hole depth, width and penetration velocity of evaporation depend on different parameters such as power, material, exposure time, distance between drilling tool and the material, the drilling tool, etc. In this paper; the laser beam was used as drilling tool. 16W CO2 laser (10.6μm) and transparent Perspex (PMMA) which is the abbreviation of polymethyl methacrylate work piece with 8mm thickness were used. The distance between laser beam and the material was 5cm. Different powers for CO2 laser were used for different exposure time. Hole depth, time required for boiling, heat flow per unit area and penetration velocity of evaporation were calculated. Measured and calculated results were approximately the same. Many figures which representing the relations between laser power, time to reach boiling, hole width, hole depth and exposure time were obtained by using Matlab 2008 software program
