A method of supplying circuit components to a component mounting device from a feeder. The component mounting device removes the components from the feeder and transfers them to and mounts them on a circuit substrate. The method includes providing a plurality of feeders which each include a main portion, a feeding mechanism, a component supply portion and a component holding portion. The component holding portions hold the circuit components. The main portions of the feeders are mounted on a movable table such that the component holding portions of the feeders are arranged along a line. The main portions support the feeding mechanisms, which feed the circuit components one by one from the component holding portions to component supply portions. The movable table is moved along the line. The movable table is intermittently stopped so that the component-supply portions of each of the feeders are sequentially positioned at a component supply position, at which each feeder supplies at least one circuit component from its component supply portion. When the movable table and the feeder main portions are accelerated and decelerated, the component holding portions and the components held thereby accelerate and decelerate at a lower rate.

A circuit board manufacturing system is provided which includes a production assembly line with a carrier handling system for a plurality of feeder/programming/buffer systems. The feeder/programming/buffer system has a flexible feeder mechanism for s receiving unprogrammed device in a number of different manners, a programming mechanism for performing a programming operation on the unprogrammed devices at a high rate of speed, and a buffer mechanism for providing the programmed micro devices to the carrier handling system. The carrier handling system has its own buffer section and is integrated with an assembly handling system of the production assembly line to populate the programmed devices on to the circuit boards.

Placement head and placement system for a placement apparatus for placing components in a placement plane, at least one placement head being provided with at least one gripper for picking up and/or putting down the components. The gripper is fitted in an edge region of the placement head, with the result that, in the case of a projection of the placement head onto the placement plane, the image of the gripper situated in the placement position essentially does not project from the image of the placement head. According to the invention, simultaneous independent placement using a plurality of placement heads is possible without the risk of a collision of the placement heads.

An electronic components mounting device has a plurality of feeder bases attached with tape feeders thereon, and a guide rail and a cylinder for drawing each of the feeder bases independently to a position for replenishing electronic components. When an electronic component runs out of the storage, only the feeder base that is carrying the relevant tape feeder gone out of the stock is drawn to a place for parts replenishment; in the mean time, the mounting actions keep on going by making use of tape feeders attached on other feeder base. Machine stop times can be decreased with the mounting device.

A process for the production of a device for measuring or detecting, particularly a probe or a detector, includes the steps of pre-mounting the different active components of the device, of which certain are ultimately gathered in functional subassemblies on and/or in a support body, then potting the pre-mounted resulting assembly, as well as its connection regions with a connection and/or supply cable, to form a substantially monoblock member and, finally, overmolding under pressure the potted member, as well as the proximal portion of the cable, with a thermoplastic material compatible with the resin used, to obtain an apparatus or instrument having the desired shape.

A method of IC packing/unpacking for preserving and updating data stored in the IC and the structure thereof is disclosed. The method is able to encase the IC to prevent intentional piracy and allow data preservation and update. The structure has an upper plate (10) having a trough (12) defined therein; a lower plate (20) detachably connected with the upper plate (10); a PCB (30) sandwiched between the upper plate (10) and the lower plate (20) and forming an electrical connection with the upper plate (10); an interface (60) detachably inserted into the trough (12) and being able to receive data therein; and a controller (50) electrically connected with the interface (60) for coding the interface (60).
摘要:
There is provided a production line having a plurality of mounting apparatus of electronic components in which the overall production efficiency is sustained by an alternation scheme when a mounting apparatus has a long cycle time due to a high malfunction rate. At a predetermined timing, the rate of unsuccessful pick-up procedure for an electronic component is compared to a predetermined value. If the rate is higher than the value, CPU finds out if the mounting apparatus 2, or 3 is available as an alternate. When the alternate is the apparatus 2, CPU 10 changes the command parameter of the particular mounting procedure, stored in RAM 12, from “M” to “S”, and stops mounting the same component. In the mean time, the mounting apparatus 2 accepts the alternate request from the apparatus 1, changes the command parameter as required, and mounts the same component on a print circuit board.

A printed circuit board includes a first mark 2 formed by a thin conductor, a second mark 3 formed by a resist 8, a land 6 which is partially coated by the resist 8 and a land 7 which is not coated by the resist 8. The second mark 3 is formed when the land 6 is partially coated by the resist 8. A device 4, which corresponds to the land 6, is mounted at a position apart from a center 02 of the second mark 3 by a predetermined distance L1. A device 5, which corresponds to the land 7, is mounted at a position apart from a center 01 of the first mark 2 by a predetermined distance L2. Therefor, the devices 4, 5 can be properly mounted on the printed circuit board 1 in spite of a positional error of the resist 8.
