    摘要: A system includes a utility meter with a first conductive member and a circuit board coupled to the first conductive member at a first joint. The first joint is disposed along a first elongated strip portion of the circuit board. The first elongated strip portion is configured to flex relative to a main portion of the circuit board in response to thermal expansion or thermal contraction of the first conductive member or a component coupled to the first conductive member.
