Abstract

A printed wiring board ( 1 ) includes: a base substrate ( 3 ); a plurality of pads ( 15 a, 17 a ) for electrical connection that are disposed at one surface side of the base substrate ( 3 ) and at a connection end portion ( 13 ) to be connected with another electronic component ( 50 ); wirings ( 9, 11 ) that are connected with the pads ( 15 a, 17 a ); and engageable parts ( 28, 29 ) that are formed at side edge parts of the connection end portion ( 13 ) and are to be engaged with engagement parts ( 58 ) of the other electronic component ( 50 ) in the direction of disconnection. The flexible printed wiring board ( 1 ) further includes reinforcement layers ( 31, 32 ) that are disposed at the other surface side of the base substrate ( 3 ) and at a frontward side with respect to the engageable parts ( 28, 29 ) when viewed in the direction of connection with the other electronic component, and that are formed integrally with the wirings ( 9 ).

First claim

The invention claimed is:

1. A printed wiring board comprising:
a base substrate;
a plurality of pads for electrical connection that are disposed at one surface side of the base substrate and at a connection end portion to be connected with a connector, the plurality of pads forming front and rear two arrays when viewed in a direction of connection with the connector;
first wirings that are provided at the other surface side of the base substrate and connected with pads of the front array of the plurality of pads via vias penetrating the base substrate; and
second wirings that are provided at the one surface side of the base substrate and connected with pads of the rear array of the plurality of pads, wherein
the first wirings are provided so as to pass through respective positions at the other surface side of the base substrate corresponding to the pads of the front array and the pads of the rear array,
the first wirings have first expanded-width parts provided at positions on the other surface side of the base substrate corresponding to the pads of the front array and second expanded-width parts provided at positions on the other surface side of the base substrate corresponding to the pads of the rear array,
the first expanded-width parts have shapes corresponding to shapes of the pads of the front array, and
the second expanded-width parts have shapes corresponding to shapes of the pads of the rear array.

2. The printed wiring board according to claim 1 , comprising:
an engageable part that is formed at a side edge part of the connection end portion and is to be engaged with the connector in a direction of disconnection; and
a first reinforcement layer that is provided at the other surface side of the base substrate and at a frontward side with respect to the engageable part when viewed in a direction of connection with the connector.

3. The printed wiring board according to claim 2 , wherein the first reinforcement layer is formed integrally with any of the first wirings.

4. The printed wiring board according to claim 2 , wherein the first reinforcement layer is formed separately from the first wirings.

5. The printed wiring board according to claim 1 , comprising:
an engageable part that is formed at a side edge part of the connection end portion and is to be engaged with the connector in a direction of disconnection; and
a second reinforcement layer that is provided at the one surface side of the base substrate and at a frontward side with respect to the engageable part when viewed in a direction of connection with the connector, wherein the second reinforcement layer is provided integrally with at least any one of the pads and the second wirings.

6. A connecter connecting the printed wiring board according to claim 1 with another wiring board, the connector comprising:
a housing that has an insertion opening into which the connection end portion of the printed wiring board is inserted; and
a plurality of contacts that are provided to correspond to the plurality of pads of the printed wiring board inserted in the housing.
