A ruggedized, snap-together, module securely retains a pair of mutually abutting fiber optic interconnect MT ferrules, that have been joined together by a ferrule aligning pin clamp structure. Thus, original data having 127-bit length 126:0 is inputted at step S1. Width adjusters for the transfer path, the accommodating section, and the component feeding section are installed respectively on the transfer path, accommodating section, and component feeding section to adjust widths thereof according to widths of the carrier tape, the accommodating section, and the component feeding section, respectively. The card controller further comprises a means for detecting the format of the electronic device and generating a response signal containing the format of the electronic device. The second image sensor has a rolling-shutter readout arranged in portrait orientation. Thereafter, interconnections and the like are then formed on the prepreg, to thereby complete a multilevel interconnection board.
