Abstract

The invention provides a drying system for a flexible circuit board. The drying system comprises two conveying devices, four rotating shafts, offset mechanisms, a hot air device and a cold air device, wherein the two conveying devices are made of polytetrafluoroethylene materials and comprise an upper conveying belt and a lower conveying belt which are close and parallel to each other; the four rotating shafts are arranged at two ends of one conveying device and two ends of the other conveying device and are used for driving the transmission of the conveying belts; the offset mechanisms are arranged on the rotating shafts and are used for adjusting the tension of the upper conveying belt and the lower conveying belt; the hot air device is used for blowing hot air out and comprises an air heater and a hot air cutter; the air heater is connected with the hot air cutter by an air heater hose; an electric heater for heating is arranged between the air heater hose and the air heater; the cold air device is used for blowing cold air out, and comprises an air cooler and a cold air cutter; the air cooler is connected with the cold air cutter by an air cooler hose; and a heat-insulating plate is arranged between the cold air device and the hot air device and is used for isolating the cold air from the hot air.

Description

technical field

[0001] The present invention and a drying system for flexible circuit boards, in particular, relate to a drying system for flexible circuit boards that can dry without deviation, discount, or indentation. Background technique

[0002] At present, the structural design of attached circuit components is developing towards miniaturization and thinning, and the application of thinner or small imposition flexible circuit boards is becoming more and more popular. The production process of thinner or small imposition flexible circuit boards uses traditional Under the pressure of the cold and hot air knives blowing out of the special roller-type horizontal conveying dryer, it is easy to cause its gold surface to be scratched, and the surface will be indented or discounted, which will reduce the yield rate. Contents of the invention

[0003] In order to solve the above technical problems, the present invention provides a drying system for flexible circuit boards, in...
