“…Also, pumps based on thermal expansion of air have been developed before and can be integrated with relative ease [6]. However, they use a significant amount of space, and furthermore the created flow is pulsed [7], [8].…”

This paper presents the design and fabrication process of a microfluidic pump based on the electroosmotic effect, and demonstrates its working. The device is fabricated using a combination of standard PCB processing and SU-8 photolithography, using Flame Retardant 4 (FR4) as substrate, SU-8 as structural material to construct the microchannels and chambers, and copper to built the lines for the electrical connections. The fabrication materials provide an inexpensive device. The proposed pump is intended to be included in SU-8 microfluidic portable platforms as an impulsion device which provides a continuous flow rate. Preliminary experimental results show an electroosmotic effect at 60 V, providing a flow rate of 1 µL/min.

“…These advantages, that is, their low cost and precise dimensions, together with the characteristics of the PCB, made this substrate an interesting material to perform applications for which the PCB was not intended. Regarding this, microelectromechanical systems (MEMS), which typically and historically used silicon as base material, adopted the Printed Circuit Board as an alternative material due to its advantage of having one or more copper layers to fabricate microchannels, sensors or actuators, and the ability to include microfluidics and electronics in the same substrate at a low cost [ 10 , 11 , 12 , 13 , 14 , 15 ]. These devices were named PCB-MEMS, and formed the origin of much more developments thanks to the application of lab-on-a-chip (LoC) devices.…”

This paper describes the fabrication opportunities that Printed Circuit Boards (PCBs) offer for electronic and biomedical engineering. Historically, PCB substrates have been used to support the components of the electronic devices, linking them using copper lines, and providing input and output pads to connect the rest of the system. In addition, this kind of substrate is an emerging material for biomedical engineering thanks to its many interesting characteristics, such as its commercial availability at a low cost with very good tolerance and versatility, due to its multilayer characteristics; that is, the possibility of using several metals and substrate layers. The alternative uses of copper, gold, Flame Retardant 4 (FR4) and silver layers, together with the use of vias, solder masks and a rigid and flexible substrate, are noted. Among other uses, these characteristics have been using to develop many sensors, biosensors and actuators, and PCB-based lab-on chips; for example, deoxyribonucleic acid (DNA) amplification devices for Polymerase Chain Reaction (PCR). In addition, several applications of these devices are going to be noted in this paper, and two tables summarizing the layers’ functions are included in the discussion: the first one for metallic layers, and the second one for the vias, solder mask, flexible and rigid substrate functions.
