Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit board production, in particular to a filtering device for flexible circuit board production. Background Art

[0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties, can meet the design needs of smaller and higher density installations, and also help reduce assembly processes and enhance reliability. They are widely used in the production of mobile phone antennas. A large amount of wastewater is generated during the production of flexible circuit boards, which is difficult to treat. If it is not effectively treated, it will seriously damage the environment after being discharged;

[0003] In a patent entitled "A Wastewater Treatment Device for Circuit Board Production" with a Chinese publication number of CN216404118U, an electromagnetic filter is provided so that iron and larger particle impurities in the wastewater are screened on the electromagnetic filter, and the filtered wastewater is immersed in a sponge filter element, so that the sponge filter element is saturated with absorption. At this time, the gravel layer moves upward through a slide rail, and the gravel layer squeezes the sponge filter element, so that the wastewater is squeezed down, and some small particles and pigments in the wastewater are left in the sponge filter element, so that the wastewater is filtered for a second time, and at the same time, the wastewater is filtered again when passing through the gravel layer. The wastewater after three filtrations falls to the bottom of the shell, and the wastewater is subjected to sedimentation treatment by the setting of a reagent kit and a stirring device. The filter plate limits impurities, so that copper is separated from water, and then the wastewater generated in the production of circuit boards is treated, and the device is integrated and vertically arranged, with a small footprint and space saving;

When the device needs to be used in different locations and needs to be moved, it is inconvenient to move and transport it, which is not conducive to people's use. In view of the above problems, the inventor proposes a filtering device for flexible circuit board production to solve the above problems. Utility Model Content
