歪み波形制御装置、歪み規制部材、歪み波形制御装置の歪み波形制御方法、及び歪み波形制御プログラム
Document Type and Number:
Japanese Patent JP3857708
Kind Code:
B2
Abstract:
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.
