摘要： The present invention relates to a high yield apparatus for drying rigid or flexible printed circuit boards. The apparatus comprises a box-like structure which defines a drying tunnel, having an inlet opening and an outlet opening. The apparatus comprises moreover heated air circulating means for circulating heated air inside the tunnel as well as driving means for driving the printed circuit boards along the tunnel. The driving means comprise at least a pair of chains which are arranged parallel to one another and are entrained about a first pinion and a second pinion, having parallel axes, and respectively located near the inlet opening and near the outlet opening. The chains are provided with gripping means for supporting the printed circuit boards along the tunnel. The gripping means are suitable to automatically engage the printed circuit boards near the inlet opening and to automatically release the printed circuit boards near the outlet opening.
