Abstract:
An improved method for soldering the terminals of a rigid printed circuit board to those of a flexible printed circuit board, such method comprising the steps of focusing a radiant heating source upon each of a plurality of solder globules deposited in a like number of through holes in the terminals of the rigid printed circuit board for controlling of the capillary flow of the molten solder radially from the through holes to form solder points of controlled depth and pattern between the terminals of the boards.
Abstract:
An electronic apparatus includes a printed circuit board, a terminal and a surge voltage protection structure. The printed circuit board includes a first plated through hole, a second plated through hole and a ground terminal. The surge voltage protection structure includes the first plated through hole and the second plated through hole. The first plated through hole is electrically connected to the terminal. The second plated through hole is connected to the ground terminal. A gap is defined between the first plated through hole and the second plated through hole. The first plated through hole receives a surge voltage to generate an electric arc across the gap and transmit the electric arc through the gap to the second plated through hole, so that the second plated through hole receives the electric arc to transfer an energy of the electric arc to the ground terminal.
Abstract:
Systems and methods for printing a printed circuit board (PCB) from substrate to full integration utilize a laser-assisted deposition (LAD) system to print a flowable material on top of a substrate by laser jetting to create a PCB structure to be used as an electronic device. One such system for PCB printing includes a jet printing unit, an imaging unit, curing units, and a drilling unit to print metals and other materials (epoxies, solder masks, etc.) directly on a PCB substrate such as a glass-reinforced epoxy laminate material (e.g., FR4) or others. The jet printing unit can also be used for sintering and/or ablation of materials. Printed materials are cured by heating or by infrared (IR) or ultraviolet (UV) radiation. PCB s produced according to the present systems and methods may be single-sided or double-sided.

Abstract:
A wired circuit board having terminals that can provide reliable placement of molten metals on the terminals, to connect between the terminals and the external terminals with a high degree of precision. An insulating base layer 3 is formed on a supporting board 2, and a conductive pattern 4 is formed on the insulating base layer 3 so that a number of lines of wire 4a, 4b, 4c, 4d, magnetic head connecting terminals 7, and external connecting terminals 8 are integrally formed and also first through holes 9 are formed in the external connecting terminals 8. Thereafter, after an insulating cover layer 10 is formed, third through holes 20 and second through holes 19 are formed in the supporting board 2 and in the insulating base layer 3, respectively, to communicate with the first through holes 9. This can provide the result that when the external connecting terminals 8 are connected to the external terminals 23, the connection can be performed while confirming the placement of the solder balls 21 from the respective through holes.
