Strain waveform control apparatus, strain waveform regulating member, strain waveform control method by using strain waveform control apparatus, and strain waveform control program

摘要

A strain waveform control apparatus of the present invention is adapted to horizontally supporting a printed circuit board over a trestle and cause strains on the printed circuit board by a dropped rigid ball with buffer blocks being located on both surfaces of the printed circuit board. These buffer blocks are movably supported by movable stages so as to be in contact with proper places of both surfaces of the printed circuit board. The buffer blocks are capable of regulating and relatively modify/adjusting first and second occurred strain waveforms generated by application of the impact to the printed circuit board and modifying/adjusting a steepness of each of the strain waveforms.
