PROBLEM TO BE SOLVED: To provide a circuit board that allows performing a mounting-strength test at low cost. SOLUTION: A multiple surface mounting board 10 is provided with a plurality of circuit boards 12 and substrates 14 for a chip mounting strength test. Each of the plurality of circuit boards 12 has on a major surface a chip mounting region on which on-board components are mounted. The substrates 14 for the test are provided in spaces between neighboring circuit boards 12. COPYRIGHT: (C)2006,JPO&NCIPI
