ELECTRONIC CIRCUIT APPARATUS FOR COMPRESSOR

摘要

An electronic circuit apparatus for a compressor includes board (120) and case (110). One corner of board (120) is fixed to case (110) such that board (120) cannot move in the thickness direction and is movable in the flattening direction. According to this structure, even when an electronic part generates heat or outside air temperature of case (110) varies, the expansion or contraction of board (120) in the flattening direction is not affected by the expansion or contraction of case (110) in the flattening direction. Therefore, it is possible to prevent the deformation of board (120) and stress from being repeatedly applied to a soldering portion of the electronic part. As a result, it is possible to ensure the reliability of soldering strength for a long time.
