<p><P>PROBLEM TO BE SOLVED: To provide a reliable control means without being affected by water, liquid, noxious insects, or the like. <P>SOLUTION: An equipment (not shown in Figure) comprises an electronic component 12c, a printed board 12a on which the electronic component 12c is mounted, and a protective material which tightly contacts at least two surfaces of the six surfaces of the printed board 12a and covers the printed board 12a. Since water, liquid, or noxious insects does not directly contact the lead or solder of the electronic component 12c, there exists no effect of water or noxious insects for stability and reliability. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
