“…This device was fabricated using SU-8 as an additional material, and PCB as a substrate to fabricate both the microvalve and the electrical connection needed for activation. In contrast, a single-use and normally open microvalve was developed in Reference [ 137 ]. In this case, the closing was achieved thermally by the melting of a PMMA microchannel using an integrated microheater.…”

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.

“…40 In this method bonding area is heated up to near the transition temperature of PMMA and a moderate pressure is applied. 41 While gas-phase microuidic devices are similar to liquidphase microuidic devices, special fabrication challenges are encountered in gas phase. In the case of small size gaseous analytes, device sealing can be more difficult.…”
