Description

Adjustable plate rack

The invention relates to a board frame, in particular to an adjustable board frame.

In the process of making a circuit board, it is necessary to dry the printed material on the circuit board through a drying operation. In the current prior art, when the circuit board is baked, the circuit board is first placed on a board rack. The board rack has a plurality of clamps to hold the top side of the circuit board. Then, the plate rack is placed on the conveying mechanism of the oven, and the plate rack with the circuit board is driven into the oven for drying. With the thinning and thinning of electronic products in recent years, the thickness of circuit boards has also been greatly reduced, making the overall weight lighter. During the baking process, the circuit board on the board rack in the oven is only held on the top side. It may be caused by the hot air blowing inside the oven, which may cause deformation of the circuit board itself, and may also cause contamination of printed materials between adjacent circuit boards that are not yet dried, which reduces the yield.
