摘要： In the first buffering area provided between the inlet of the furnace and the heating chamber, the ambient gas is blown to the printed circuit board from the lower side of the carrier device, while the ambient gas is sucked in the upper side of the carrier device, thus the outside air is prevented from infiltrating and the ambient gas is prevented from flowing out. Furthermore, the flux is prevented from being attached to the printed circuit board, by installing the flux dropping prevention mechanism in the suction port of the ambient gas.

摘要： A reflecting base material that can reliably prevent the occurrence of uneven brightness, a backlight unit that uses the same, and a method for manufacturing the same are provided. Surface profile information of the reflecting base material 7 is obtained by a laser displacement gauge 3. Next, the unevenness information obtained is subjected to Fourier transform, and the relationship between frequency and intensity for the surface unevenness profile of the reflecting base material is obtained. Next, the calculated relationship between the frequency and intensity is compared with a preset standard data. When the intensity exceeds 0.6 at a predetermined range of frequency domain, a judgment of rejection is made; when no data exceeding 0.6 exists in said judgment domain, a judgment of acceptance is made.
