PURPOSE:To remove a lead type electronic part easily from a printed board, and to reuse the removed electronic part by using a shape memory alloy as the terminal material of the electronic part and fixing the electronic part onto the printed board without soldering. CONSTITUTION:A linear shape is stored in the terminals 2 of a lead type electronic part 1 using a shape memory alloy at a high temperature, and the terminals 2 are machined in a form bent at the normal temperature. When the lead type electronic part 1 is loaded on a printed board 3, the terminals 2 of the lead type electronic part 1 are heated, formed in the linear shape and inserted into the through-holes 4 of the printed board 3. Consequently, the temperature of the lead type electronic part 1 load on the printed board 3 at the high temperature is returned to the normal temperature, and the terminals 2 of the lead type electronic part 1 are press-contacted with the electrodes 5 of the printed board 3, and brought to a conductive state. When the lead type electronic part 1 is removed from the printed board 3, the terminals 2 are heated, and taken off in the linear shape. |
