摘要:
A method of controlling contact load in an apparatus for mounting electronic components on a substrate includes moving a head holding an electronic component down by a predetermined distance. Contact load is measured after moving the head down. A determination is made as to whether the measured contact load has reached the target contact load. The moving and measuring are repeated until the measured contact load reaches the predetermined target contact load.

Provided is a light-emitting module, a light source device and a liquid crystal display device in which unevenness in the luminance and color hardly occurs as compared to conventional technology. A light-emitting module 100 is structured such that a plurality of element columns, each composed of light-emitting elements 120 arranged in line, are mounted on a substrate 110, and each element column is individually sealed by a separate sealing member 130. The light source device and the liquid crystal device each include the above light-emitting module 100.

A component mounting apparatus has a stage 41 with a fixed height position for holding a substrate 5, and a mounting head 48 that releasably holds a component 2, is moved downward toward the stage 41 from a first reference height position HB1 fixedly positioned above the stage 41, and mounts the held component 2 on the substrate 5 or an already mounted component 2. A controller 14 has a mounting reference height calculation unit 103 for calculating a mounting reference height Hn corresponding to a distance from the first reference height position HB1, and a first target movement height calculation unit 104 for calculating a first target movement height ZTAGn based on at least the mounting reference height Hn and a thickness PTn of the component 2 held by the mounting head 48. The controller 14 moves the mounting head 48 holding the component 2 downward from the first reference height position HB1 to the first target movement height ZTAGn to mount the held component 2 on the substrate 5 or the already mounted component 2.
摘要:
A method of controlling contact load in an apparatus for mounting electronic components on a substrate, in which a head is lowered at high speed to slow down starting position where there is no risk that the electronic component makes contact with the substrate (S1), and from there the head is lowered at low speed until a predetermined target contact load is detected. The process of lowering the head at low speed includes the steps of moving down the head a predetermined distance (S3), measuring load after the step of moving down the head (S5), and determining whether the measured contact load has reached the target contact load (S9). The steps of moving down the head (S3) and measuring the load (S5) are repeated until the measured load reaches the target contact load. The actual load is precisely controlled to be close to a very small set level of target contact load. Accordingly, electronic components using low dielectric constant material are mounted without the risk of damage.

摘要:
A circuit layout pattern inspection method and a logical simulator for implementing the same. Wiring is substituted by a .pi. or T equivalent circuit and is described by a nodal equation, and a gate is described by a simplified model, that is, a current source calculation formula. By the nodal equation and the current source calculation formula, a simulation is performed to obtain a delay time for every node. The obtained delay time is stored to make the inspection easy.
