    • PROBLEM TO BE SOLVED: To provide a printed board unit, capable of ensuring a bonding strength of a solder and through-hole without changing the length of a terminal. SOLUTION: In a main board unit 13, the thickness of a printed board 14 is partially decreased based on a depression 15. Even when a length of a terminal 19 is smaller than an original thickness of the printed board 14, a distal end of the terminal 19 can protrude from the rear face of the printed board 14. The length of the terminal 19 need not be changed. Moreover, the bonding strength of a solder 21 and a through-hole 18 is amply ensured, by an operation of a fillet 22 around the terminal 19. The terminal 19 is bonded to the through-hole 18 at a sufficient strength. An omission of an electronic part 14 can be avoided from the printed board 14. COPYRIGHT: (C)2008,JPO&INPIT
    • 要解决的问题:提供能够确保焊料和通孔的接合强度而不改变端子长度的印刷电路板单元。 解决方案:在主板单元13中,印刷电路板14的厚度基于凹陷部分15部分地减小。即使当端子19的长度小于印刷电路板14的原始厚度时, 端子19的端部可以从印刷电路板14的后表面突出。端子19的长度不需要改变。 此外,通过端子19周围的圆角22的操作,确保了焊料21和通孔18的接合强度。端子19以足够的强度结合到通孔18。 可以避免印刷电路板14省略电子部件14.版权所有:(C)2008,JPO&INPIT
