Abstract
An electronic-component lead terminal includes a lead terminal one end of which is connectable to an electronic component and the other end of which is connectable to an electrode, and a solder-wicking prevention area formed on a surface of the lead terminal so as to intersect a solder-wicking direction oriented from the other end toward the one end, the solder-wicking prevention area including a plurality of portions projecting to a downstream side in the solder-wicking direction.
Claims14
An electronic-component lead terminal comprising:
- a lead terminal one end of which is connectable to an electronic component and the other end of which is connectable to an electrode;
- and
- a solder-wicking prevention area formed on a surface of the lead terminal so as to intersect a solder-wicking direction oriented from the other end toward the one end, the solder-wicking prevention area including a plurality of-portions projecting to a downstream side in the solder-wicking direction.
An electronic component comprising:
- an electronic component;
- a lead terminal one end of which is connected to the electronic component and the other end of which is connectable to an electrode pad of a printed board;
- and
- a solder-wicking prevention area formed on a surface of the lead terminal between the one end and the other end so as to intersect a solder-wicking direction oriented from the other end toward the one end, the solder-wicking prevention area having a plurality of portions projecting to the downstream side in the solder-wicking direction.
A method of fabricating an electronic-component lead terminal comprising:
- moving a lead member to which a plurality of lead terminals are bonded in a first direction;
- irradiating the lead member with a laser beam through a laser beam window that reciprocates in a direction perpendicular to the first direction;
- and
- cutting the lead terminals off from the lead member.
