Abstract: The present disclosure provides a method for manufacturing a board-to-board connection structure. The method includes defining a first through hole in a first circuit board, disposing a first connector within the first through hole by a first conductive paste, and connecting the first connector to a second circuit board on which a second connector is installed, thereby realizing a connection of the two circuit boards, and reducing a height of the two circuit boards after the connection. That is, the height of the board-to-board connection structure is reduced. Additionally, since the first connector is received within the first through hole, the first connector is not easy to be damaged and oxidized. The present disclosure further provides a board-to-board connection structure manufactured by the above method.

Abstract: Film for use in preparing a printed circuit board (PCB) along with methods for making a PCB and producing a printable film are described herein. The film includes a first layer formed of a radiation-transparent material, a second layer formed of a curable adhesive material, a third layer formed of an electrically conductive material, and optionally, a fourth layer formed of an adhesive and a fifth layer formed of a removable material. Through the adhesive layers, the layers are bonded together to produce the printable film. To produce a PCB, the first layer is covered in ink distributed in a pattern representing the PCB, and the ink-covered film is exposed to radiation until the non-ink-covered portions of the second layer have cured. Then, the fifth layer is removed tearing away the electrically conductive material associated with the non-ink-covered portions of the second layer producing the PCB.
