Abstract:
Techniques are disclosed for forming a package substrate with integrated stiffener. A panel of package substrates are provided. An adhesion layer is then formed on each package substrate of the panel of package substrates. A panel of stiffeners are then attached to the panel of package substrates by the adhesion layer, each stiffener corresponding to a respective package substrate. The panel of package substrates is then singulated into individual package substrates with integrated stiffeners. The stiffeners on the singulated package substrates include tabs that extend to the edges of the package substrates.

Abstract:
To improve reliability by preventing separation of a sheet material attached on a flexible printed circuit, provided is a flexible printed circuit including a printed board body and a reinforcing board. A leaked portion of an adhesive agent is formed to leak in an outward direction relative to an end surface of the reinforcing board. The leaked portion adheres to part of the end surface of the reinforcing board to be continuous from a lower end of the end surface to form an inclined surface tapered in the outward direction. The leaked portion is formed such that a portion thereof that covers the end surface has an adhesion height hA, as measured from an adhesive surface of the reinforcing board, of greater than 0% and not greater than 80% of the thickness H1 of the reinforcing board.
Abstract:
A suspension board with circuit includes a metal supporting board having a support opening portion passing through a thickness direction; a base insulating layer disposed on an upper surface of the metal supporting board and having an insulating opening portion passing through the thickness direction, when projected in the thickness direction, to be included in the support opening portion; and a conductive layer having a wire portion disposed on an upper surface of the base insulating layer and a terminal portion disposed in the insulating opening portion to be connected to an electronic element and connected to the wire portion. The base insulating layer has a cutout portion obtained by cutting out the base insulating layer in a direction orthogonal to the thickness direction and continuous to the insulating opening portion and the terminal portion includes a terminal free end portion opened by the cutout portion.
Abstract:
According to one embodiment, a composite substrate includes a soft layer, a hard layer, a rigid portion and a flexible portion. The soft layer includes a first conductor layer with a conductor pattern and a first flexible insulating layer. The hard layer includes a second conductor layer with a conductor pattern and a second rigid insulating layer. The rigid portion is formed by laminating the soft layer and the hard layer. The flexible portion includes a transition portion which is in proximity to the rigid portion by extending the soft layer and is wider than an interconnect portion.

Abstract:
Substrates for electronic components are disclosed. In some example embodiments, a light source is provided with a substrate, at least one electronic package coupled to said substrate by an adhesive at an associated mounting location, and a stiffener proximate to said mounting location for reducing flexing of said substrate in said mounting location compared to flexing of said substrate in said mounting location in the absence of said stiffener.
Abstract:
A mounting structure includes a bonding material (106) that bonds second electrodes (104) of a circuit board (105) and bumps (103) of a semiconductor package (101), the bonding material (106) being surrounded by a first reinforcing resin (107). Moreover, a portion between the outer periphery of the semiconductor package (101) and the circuit board (105) is covered with a second reinforcing resin (108). Even if the bonding material (106) is a solder material having a lower melting point than a conventional bonding material, high drop resistance is obtained.
