Abstract: Terminal pads are arranged on a first surface of the substrate for an electronic component to receive terminals of the electronic component. An electrically-conductive film is formed on a second surface defined on the back of the first surface over the back of a mounting area for the electronic component. The mounting area is contoured along the outer periphery of the arrangement of the terminal pads.

This results in suppression of flexure of the printed wiring board during reflow.

Abstract: In a dispersion compensating apparatus, a reference identifying unit identifies a reference (X dB down) that makes a penalty lower than a predetermined value in accordance with optical signal information and a reference identifying table, and a VIPA plate temperature adjusting unit adjusts a refractive index of a VIPA plate by modifying a temperature of the VIPA plate so that a transmission center wavelength derived from the reference matches the wavelength defined by an ITU-T Grid. If a dispersion compensation value setting unit performs an optimal residual dispersion value search, the VIPA plate temperature adjusting unit determines if a filtering penalty is lower than a predetermined value in accordance with a penalty management table. If the filtering penalty is lower than the predetermined value, temperature adjustment of the VIPA plate is not performed.
