用チエーン。 A conveyance chain in a reflow oven in which a printed circuit board is mounted on the opposing protruding tips of each pin that connects each link of a pair of link chains, and is conveyed and soldered, and the protruding inner end of each pin. The section is composed of a large diameter section and a small diameter section formed at the tip of the large diameter section, and a gap is provided between both end surfaces of the printed circuit board mounted on the small diameter section and the corresponding base end surface of each large diameter section. For transportation in a reflow oven, characterized in that a bush that fills the gap is inserted into the small diameter part of every other pin and fixed to widen the hot air passage gap between the link chain and the printed circuit board. Chain.
