Abstract: At a conveyor forefront portion, velocity distribution of an airflow is provided. The velocity distribution is wind velocity distribution in a vertical direction of an airflow from a surface of an upper rectifying plate to a surface of a conveyor at the conveyor forefront portion, and has a maximum value in a range of less than 10 mm downward of the vertical direction from the rectifying plate surface. Moreover, a ratio obtained by dividing the maximum value by a wind velocity in the vicinity of the surface of the conveyor is 4 or more, and 12 or less. In a range other than the range of less than 10 mm, the airflow has a wind velocity equal to the wind velocity in the vicinity of the surface of the conveyor.

Abstract: A resin is irradiated with an infrared ray, and a reflected ray from the resin irradiated with the infrared ray is received. In a reflection or absorption spectrum obtained by the reflected ray, a difference of a reflection intensity in a spectrum between a first wave number band of 1340 cm−1 to 1350 cm−1, inclusive, and a second wave number band of 1300 cm−1 to 1340 cm−1, inclusive, is calculated. It is determined whether or not a specific bromine-based flame retardant is contained in the resin, by using the calculated difference of reflection intensity in the spectrum.

Abstract: A method and an apparatus for collecting flux in a way that improves the cleanliness inside a furnace by improving flux collection efficiency, reduces flux viscosity to maintain a liquid state even at ordinary temperature, and makes the flux collection unit more easily serviceable includes a rosin particle contained in an atmosphere gas, and vapor of a solvent or an atomized solvent particle are mixed in a mixing section provided upstream of a flux collection unit-side inlet, and a gas containing a mixed particle is cleaned by means of electrostatic precipitation. The solvent particle adheres to the rosin particle, and forms an aggregate of large particle size that can be more easily charged by corona discharge. This improves the flux collection rate of electrostatic precipitation collection, and, because the rosin particle dissolves in the solvent particle, the collected flux can have reduced viscosity.

Abstract: A separation apparatus includes a first air blower, a plurality of regulating plates, and a second air blower. The first air blower generates a first airflow toward a jumping direction of a separation target at a tip end of the conveyor. The first airflow has a wind speed that matches a transporting speed of a conveyor. The regulating plates are disposed along a flight path of the separation target. The second air blower generates a second airflow toward the flight path from below the flight path.
