Abstract
Provided are a receptacle assembly and a circuit board in which routing of internal layer wirings is taken into consideration. Some of the plurality of first internal layer wirings 134 are drawn toward the second electrode line L2 when viewed in the depth direction Dd, and some of the plurality of second internal layer wirings 134 are drawn toward the first electrode line L1 when viewed in the depth direction Dd.
Claims14
A receptacle assembly comprising:
- a circuit board having a first face and a second face that is the backside of the first face;
- and
- a connector mounted on the circuit board and configured such that an external module is inserted into the connector along a first direction substantially orthogonal to the first face,
- wherein when a direction orthogonal to the first direction is defined as a second direction, and a direction orthogonal to the first direction and the second direction is defined as a third direction, the connector includes
- a plurality of contact pins contacted to the external module, and
- a housing holding the plurality of contact pins,
- wherein the plurality of contact pins form a first pin group that includes contact pins aligned in a line along the second direction and a second pin group that includes contact pins aligned in a line along the second direction and is arranged at a distance in the third direction from the first pin group, and
- wherein the circuit board includes
- a plurality of electrodes provided to the first face, each of the contact pins being mounted on each of the electrodes, and
- a plurality of internal layer wirings formed in an internal layer between the first face and the second face and connected to each of the electrodes through a via,
- wherein the plurality of electrodes form a first electrode line that includes a plurality of electrodes aligned in a line along the second direction and on which the contact pins included in the first pin group are mounted and a second electrode line that includes a plurality of electrodes aligned in a line along the second direction and is arranged at a distance in the third direction from the first electrode line and on which the contact pins included in the second pin group are mounted,
- wherein the plurality of internal layer wirings include a plurality of first internal layer wirings connected to the plurality of electrodes included in the first electrode line and a plurality of second internal layer wirings connected to the plurality of electrodes included in the second electrode line,
- wherein some of the plurality of first internal layer wirings are drawn toward the second electrode line when viewed in the first direction, and
- wherein some of the plurality of second internal layer wirings are drawn toward the first electrode line when viewed in the first direction,
- wherein the circuit board includes a through-opening formed so as to penetrate from the first face to the second face,
- wherein the through-opening is a hole for guiding air that has passed through a heat sink which removes heat from the external module and flows along the first direction to an external space adjacent to the second face,
- wherein the through-opening extends in the second direction to be parallel to the first electrode line and/or the second electrode line in a region in which the internal layer wirings are not formed.
