Circuit board with resistor, light micrograph

Light micrograph of a section through a computer multilayer printed circuit board (PCB) with a surface mounted device (SMD) resistor. A small part of the PCB was embedded in light curing resin and then ground and diamond polished. The image shows the basic epoxy material of the PCB with glass reinforcement filaments in linen weave in blue (bottom). The light blue block represents the basic material of a SMD resistor, shown here in cross section. Microscopic contrast technique: Incident brightfield combined with UV excitation fluorescence. Magnification 100x when printed 10 centimetres wide.
