Abstract
An electric signal taking-out method and a device therefor capable of taking out electric signals for measurement easily from opposite ends of an arbitrary chip part soldered to a circuit board. A pair of contact elements having sharp distal ends and bent obliquely inward are arranged so that the distal ends thereof face each other. The contact elements are shifted inward by a holding member so that the distal ends bite into solder joints by which the chip part is soldered to the circuit board. The contact elements are held in the biting state so that electric signals are taken out independently from the respective contact elements.
Claims8
An electric signal taking-out method comprising the steps of:
- arranging 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;
- 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 in a biting state, to thereby take out electric signals independently from said pair of contact elements.
An electric signal taking-out device comprising:
- a pair of contact elements made of an electrically conductive material, each including a distal end portion which is bent obliquely inward and which has a sharp distal end, said pair of contact elements being arranged in such a manner as to be electrically insulated from each other and to be opposite each other while said sharp distal ends thereof face each other;
- and
- a holding member for drawing said pair of contact elements toward each other so as to press said distal ends of said contact elements onto an object to be measured, to thereby make said distal ends of said contact elements bite into the object, and holding said pair of contact elements in a state where said distal ends of said pair of contact elements are biting into the object.
