A method of simultaneously bonding components, comprising the following steps. The vehicle restraint system also comprises first and second lap belt retractors for the first and second lap belts, respectively. Thereafter, a transmission image data signal in which unit transmission blocks, each constituted by adding an inversion flag immediately before the clock data, are consecutively arranged is transmitted to a display panel driver. The carrier with the bonded hard press particles is pressed to the surface and an embossing is formed when the carrier with the hard press particles is removed. The film thickness distribution of the first thin film is measured by reflection spectroscopy in a manner that a surface of the first wafer is irradiated with a light to selectively measure only reflected light at a selected waveband. The bump material may enter a yield state.
