An apparatus for forming openings in printed circuit boards includes a work table for supporting the printed circuit boards, and at least one drilling unit movable relative to the work table. The apparatus uses drills each having a shank, a collar fitted around the shank at a predetermined position. For holding these drills, at least one first tool holding device is provided on the work table, and at least one second tool holding device of a magazine type for containing the drills parallel to each other is removably mounted above the work table. At least one transferring device is provided to operate to push a desired drill out of the second tool holding device of the magazine type, hold the pushed-out drill and transfer the same to a position where it is aligned with the drilling unit.

There is provided a functional panel that can be joined and disassembled with ease by solving problems with a functional panel including electrical conductors integrally molded therewith, causing occurrence of cracking on the surface thereof, or cracking of a molded unit around the periphery of the electrical conductor, thereby rendering the electrical conductor susceptible to a break when a flexural load, an impact load, and so forth, acts on the functional panel. The functional panel comprises a main body of a panel member, an electrical conductor coated with a semi-cured resin having heat resistance and insulation properties, and a reinforcing fiber having a continuous filament, for fixing the electrical conductor to the main body of the panel member to thereby provide enhancement, and the functional panel is formed by exposing one end, and the other end of the electrical conductor from respective end faces of the panel member formed by integral molding.

A printed circuit board fabrication method allows a fabrication time and a fabrication cost to be reduced. The fabrication method of the printed circuit board includes steps of forming a resist layer on a surface of the printed circuit board whose surface is made of an insulator, of forming a hole that is connected from the surface of the resist layer to a conductor pattern of an inner layer and a hole and grooves having a depth not connected with the conductor layer of the inner layer by irradiating lasers, of filling a conductive material into the holes and the grooves to form a conductor pattern and of removing the resist layer to project a portion of the conductor pattern out of the surface of the insulating layer.

An interposer bonding device 3 is intended for bonding an interposer 10 having an interposer-side terminal to a base circuit sheet 20 provided with a base-side terminal. The interposer bonding device 3 has a press anvil 31 that holds the base circuit sheet 20 on which the interposer 10 is laminated and a bonding head 32 that moves relatively with respect to the press anvil 31. The bonding head 32 has a pressing surface 320 that presses the rear surface of the interposer by abutting against this surface. The pressing surface 320 scans the rear surface of the interposer 10 by the relative movement of the bonding head 32 with respect to the press anvil 31 and presses the whole surface of the interposer-side terminal 12 toward the base circuit sheet 20.

The invention relates to an RFID medium 1 in which an interposer 10 having a semiconductor chip 11 mounted on a sheet-like chip holding member 13 is bonded to a sheet-like base circuit sheet 20. The interposer 10 has the IC chip 11 mounted on a substantially planar surface of the chip holding member 13, and an interposer terminal that is electrically extended from a terminal of the IC chip 11. The base circuit sheet 20 has a base terminal 22 electrically connected to the interposer terminal 12, and has a through chip housing portion 210 for housing the semiconductor chip 11 on the interposer 10.
摘要:
A laser machining apparatus in which three or more beam splits are made incident on one machining lens so that high speed machining can be achieved, and the machining quality (shapes, dimensions, accuracy and straightness of machined holes) is excellent. The optical paths of beams A and B having the same polarization direction are aligned almost in one and the same direction by a total reflection/transmission type beam combining means 31c using a difference in incident angle. After that, the optical paths of the beams A and B and the optical path of a beam C different in polarization direction therefrom are aligned almost in one and the same direction by a polarizing type beam combining means 32. Then, the beams A, B and C are made incident on a machining lens 45.
摘要:
A transfer apparatus has a first conveying device for holding and conveying a transferring-work to be transferred; a second conveying device for holding and conveying a carrier work on which the transferring-work is placed; and a transfer device to receive the transferring-work from the first conveying device and transfer the transferring-work to the carrier work of the second conveying device. The transfer device has two or more end-effectors that revolve along the same circumference to convey the transferring-work, and each of the end-effectors revolves independently of the other end-effectors. Each of the end-effectors has a holding surface that holds the transferring-work, and the holding surface is able to advance and retract along a revolution axis of each of the end-effectors.

A spare tire cover mounting structure includes a spare tire cover and a locking unit. The spare tire cover covers a spare tire supported by an outer wall portion of a door member. The locking unit includes an engagement portion provided in the spare tire cover and a locking mechanism to be engaged with the engagement portion. The locking mechanism includes a member to be engaged to be engaged with the engagement portion and an operating portion to be operated for releasing the engagement between the engagement portion and member to be engaged. The operating portion is disposed inside the outer wall portion and at a position where it can be operated in a state where the door member is closed.
