Abstract: An electronic component mounting method which employs a first air feed device connected to an air passage at one end part of a spline shaft, and a second air feed device connected to the air passage in the vicinity of the other end of the spline shaft. The first and second air feeds function to supply air to the air passage to return an interior thereof to atmospheric pressure. The time required to return the vacuum pressure in the air passage to atmospheric pressure can be shortened by the use of the two separate air feeds.

Abstract: A resin package fabrication processes comprises three steps. At the first step, a thermosetting resin-containing resin substrate is machined. At the second step carried out after the first step, the resin substrate is heated to an original glass transition temperature that the resin substrate has or a temperature that is higher than the glass transition temperature so that the glass transition temperature that the resin substrate has is elevated to a new glass transition temperature. At the third step, a resin layer is placed on at least a portion of the resin substrate to which the new glass transition temperature is imparted, and the resin substrate with the resin layer placed on that portion is then heated to the original glass transition temperature or a temperature between the original glass transition temperature and the new glass transition temperature, thereby fixing the resin layer to the resin substrate.

Abstract: In a component placement machine, a placement head (4) is driven by a linear motor (5). The stationary part (7) of the motor is attached to the machine frame (1) on which a PCB (8) is attached. The movable part (6) of the motor is connected to a slide (2) on which the placement head (4) is attached. During driving the placement head, reactive forces of the motor generate vibrations in the stationary part (7) of the motor and thus in the machine frame (20). This causes inaccuracies during the placement of components (9) on the PCB (8). To diminish this problem, the reactive forces are intercepted in a separate force frame (10) which is dynamically disconnected from the machine frame (1).

Abstract: An applicator (10) for crimping a terminal (14) onto a conductor and inserting the crimped terminal into the housing (16) of a partially assembled connector (12) includes a seating sensor for assuring that the terminal is fully inserted into the housing. A backup member (56) which is arranged to engage side edges (184) of the electrical terminal for preventing axial movement additionally makes electrical contact therewith. The pusher member includes a projection (188) that makes electrical contact with the end of the terminal only when the housing and terminal are fully seated. Electrical leads (102, 146) are electrically connected to the backup member and the pusher member so that continuity can be verified after the connector housing is fully seated. In the event that continuity is not detected, an error signal is generated indicating a malfunction.

Moreover, the receptacle and the base are replaceable with various sized ones to meet the requirement of compressing terminators of different sizes.

Abstract: In handling electronic components during manufacturing or other processing, circuit devices are retained within a dual in-line processing (DIP) tube by inserting and securing DIP pins at each end of the DIP tube. The DIP pin apparatus inserts DIP pins into holes of DIP tubes by pressing a DIP pin positioned within a lower slot of a lower plate of the apparatus into a hole of a DIP tube. The DIP pin apparatus removes DIP pins from the holes of DIP tubes by lifting a DIP pin from under its head and removing the DIP pin from the DIP tube. By using the DIP pin apparatus in the handling of electronic components, the adverse effects of operator fatigue, component damage, and production inefficiencies are reduced.

Abstract: The invention uses the conventional PC game port as a port for a digital game input device, employing a Digital Game Port (DGP) protocol which uses the four discrete or button lines and a single analog line (one of four) on the conventional game board to form a dual serial port. Data from a DGP control device is packetized with each packet consisting of 13 bytes of data. The packets or blocks are then grouped into frames. A frame consists of two blocks of data. A total of two frames are transmitted to the driver for each driver request. The 13-byte data block is divided between six one byte analog values and four bytes of digital data, with three bytes that identify and define the device. This device definition and identification is unique. By sending the device identification and configuration to the driver, the driver can determine not only the presence of the device but also very specific aspects of the device.
