Abstract:
A component mounting system and a method for inspecting mounted components are provided. A component mounting system according to an embodiment, comprises a solder inspection apparatus comparing coordinate information of the solder, which is obtained through measurement of a substrate to which solder is applied, with reference coordinate information to generate coordinate correction data; and a first mounting inspection apparatus comparing a first measurement data obtained by measuring mounting state of a component when the component is mounted based on the coordination correction data through a component mounting apparatus, with the coordinate correction data to verify whether a component is mounted on a position corrected based on the coordinate correction data. In this manner, by adding the verification function for the performance function of the component mounting apparatus to the inspection apparatus, it is possible to monitor the operation state of the component mounting apparatus in each process step.
Abstract:
There is provided an inexpensive bonding material, which can be easily printed on articles to be bonded to each other and which can suppress the generation of voids in the bonded portions of the articles to be bonded to each other, and a bonding method using the same. In a bonding material of a copper paste which contains a copper powder containing 0.3 % by weight or less of carbon and having an average particle diameter of 0.1 to 1 µ m, and an alcohol solvent, such as a monoalcohol, a diol, a triol or a terpene alcohol, the content of the copper powder is in the range of from 80 % by weight to 95 % by weight, and the content of the alcohol solvent is in the range of from 5 % by weight to 20 % by weight.
Abstract:
An object of the invention is to provide a soldering apparatus that moves the soldering apparatus at a rapid speed while ensuring that molten solder does not spill to the outside of a jet nozzle. A semiconductor device disclosed in the present description includes a solder tank that stores the molten solder, a jetting mechanism that has the jet nozzle, which extends upwards from the solder tank toward a holding surface, and a pump, which pumps the molten solder stored in the solder tank, and that jets the molten solder from the jet nozzle toward the holding surface by the pump being driven, an XY-direction moving mechanism that moves the solder tank in an X-direction and a Y-direction, which are parallel to the holding surface, and a control device that controls the acceleration and deceleration of the solder tank according to the height of the molten solder protruding upwards from a tip of the jet nozzle or the height of the molten solder protruding upwards from the tip of the jet nozzle according to the acceleration and deceleration of the solder tank such that the molten solder does not spill to the outside of the jet nozzle, when the XY-direction moving mechanism is driven to move the solder tank in the X-direction and/or the Y-direction.

Weiterhin wird eine Vorrichtung mit einem zumindest zum Teil hermetisch abgeschlossenen Gehäuse (100..125) aus Silizium angegeben, das insbesondere nach dem genannten Verfahren hergestellt ist.
Abstract:
To achieve an improvement of heat exchanger effectiveness (heat transfer rate) without any increase of a fan motor output. The gas heated by the heating units or the gas cooled down by the cooling units is sent to the blowing nozzles 2 by a fan. Then, the blowing nozzles 2 blow the gas sent by the fan through their outlets. Each of the outlets has a non-circular planar shape with a projection portion thereof being projected inwardly. This allows a shape of the gas in cross section perpendicular to a direction where the gas is blown through the outlet of each of the blowing nozzles 2 to be changed by the projection portion with time (switching phenomenon) . Such a stitching phenomenon enables to be increased the heat exchanger effectiveness (heat transfer rate) on the printed board even if any output of the fan motor for rotating the fan does not increase.
