Abstract:
A wiring board includes a first insulating layer containing a thermosetting resin, a first wiring layer stacked on an upper surface of the first insulating layer, a second insulating layer stacked on the upper surface of the first insulating layer, a second wiring layer stacked on an upper surface of the second insulating layer, and a third insulating layer stacked on the upper surface of the second insulating layer. The second and third insulating layers contain a first photosensitive resin. An outer side surface of the second insulating layer is flush with an outer side surface of the first insulating layer. An outer side surface of the third insulating layer is located inside the outer side surface of the second insulating layer in a plan view. The upper surface of the second insulating layer connecting to the outer side surface thereof is exposed from the third insulating layer.
Abstract:
A breakaway RFID tag is configured such that it comprises part of a Printed Circuit Board Assembly (PCB). Thus, the breakaway RFID tag can be used to track the PCB as it migrates through a manufacturing process. In one embodiment, the RFID tag can be assembled first and then used to track the PCB as it is populated with components and installed into larger assemblies and ultimately into the end device. Once the PCB is installed into a larger assembly or the end device, the breakaway RFID tag is configured such that it can be broken off and attached to the outside of the larger assembly or end device.

Abstract:
A method for forming a printed circuit board is disclosed. A substrate including a first device region, a second device region and a dicing channel region between the first device region and the second device region is provided. A first circuit is formed on the substrate. An insulating layer is formed on the first circuit and the substrate. At least one build-up circuit is formed on the insulating layer. A photoresist layer is formed on the at least one build-up circuit. An image transferring process is performed to pattern the photoresist layer to form a dam structure in the dicing channel region. A solder mask layer is formed on the at least one build-up circuit. The dam structure is removed to form a trench in the solder mask layer.
Abstract:
Methods to systematize the development of machines using inexpensive, fast, and convenient fabrication processes are disclosed. In an embodiment, a folding pattern and corresponding circuit design can provide the blueprints for fabrication. The folding pattern may be provided (e.g. laser machined) on a flat sheet of substrate material, such as a polymer. The circuit pattern may be generated by etching or applying (e.g. sputtering) a copper foil layer onto the substrate. Circuit components and actuators may then be added at specified locations. The flat substrate may then be folded along the predefined locations to form the final machine. The machine may operate autonomously to perform a task.
