Abstract:
An electronic part comprising:a printed circuit board including a first major surface and a second major surface; a circuit element disposed on the first major surface of the printed circuit board; a terminal electrode disposed on the second major surface of the printed circuit board and including a respective major surface opposed to the second major surface of the printed circuit board; a soldering-resistant film disposed on the second major surface of the printed circuit board and including a respective major surface opposed to the second major surface of the printed circuit board; wherein the distance between the major surface of the terminal electrode and the second major surface of the printed circuit board is equal to or larger than the distance between the major surface of the soldering-resistant film in the vicinity of the terminal electrode and the second major surface of the printed circuit board whereby the printed circuit board can undergo a degree of warp causing the terminal electrode to be deformed toward the first major surface of the printed circuit board without eliminating the availability of the terminal electrode to solder.
