Description

Technical Field

[0002] Flexible circuit board, also known as FPC soft board, is a printed circuit board made of flexible insulating substrate. It has many advantages that rigid circuit boards do not have. For example, it can be bent, wound, and folded freely, can be arranged arbitrarily according to spatial layout requirements, and can be moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection.

[0003] During production, flexible circuit boards need to be exposed, developed, etched, tinned and coppered, etc., and also need to be washed. After washing, the circuit boards need to be dehydrated. The existing dehydration method is that the staff uses a fan or some equipment to blow the water on the surface of the circuit board to blow away the water on the surface. After blowing it off, the staff needs to turn it over to achieve the effect of dehydrating both sides of the circuit board. However, after the water on the surface of the circuit board is blown off by this method, the surface of the circuit board is still wet. At the same time, the staff manually turning it over is time-consuming and laborious, and it reduces the dehydration efficiency of the circuit board. Therefore, an FPC flexible circuit board dehydration device is proposed to solve the above problems. Utility Model Content
