Abstract:
An electric signal read-out method, comprising:providing a pair of contact elements which include sharp distal ends and are bent obliquely inward so as to be opposite to each other so that said sharp distal ends face each other, the pair of contact elements being affixed to a holding member; sliding the holding member between a first position and a second position, the first position having a first spacing between the sharp distal ends of the pair of contact elements, the second position having a second spacing between the sharp distal ends of the pair of contact elements that is smaller than the first spacing, and upon sliding the holding member to the second position, shifting said pair of contact elements inward so as to make said sharp distal ends thereof bite into solder joints by which a chip part is soldered to a circuit board; and holding said pair of contact elements securely in a biting state, to thereby read out electric signals independently from said pair of contact elements.
