Description

Technical Field

[0001] The utility model belongs to the technical field of patch feeding equipment, and in particular relates to a flexible circuit board patch production feeding device. Background Art

[0002] Flexible circuit boards are made of polyimide or polyester film as substrates and are highly reliable and extremely flexible printed circuit boards. In order to increase the mechanical strength of flexible circuit boards and facilitate surface mounting operations, it is sometimes necessary to set reinforcing steel sheets on flexible circuit boards. The reinforcing thin steel sheets used on flexible circuit boards are small parts and require heating and curing. The traditional assembly method is to manually stick a group of steel sheets to the designated adhesive positions on the flexible circuit board that are pre-pasted with thermosetting glue, and then use an electric soldering iron or iron to heat the steel sheets and thermosetting glue to fix the steel sheets. Finally, the auxiliary assembly waste attached to the steel sheets is manually removed to complete the entire mounting operation.
