Description

Technical Field

[0001] The present invention relates to the field of welding technology, and in particular to a welding device for processing circuit boards. Background Art

[0002] Flexible printed circuits, also known as "soft boards," are printed circuits made from a flexible insulating substrate. They offer excellent electrical performance, meeting the demands of smaller and higher-density designs, while also reducing assembly steps and enhancing reliability. Flexible printed circuits are the only solution to meet the miniaturization and mobility requirements of electronic products. They can bend, roll, and fold freely, withstanding millions of dynamic bends without damaging the conductors. They can be arranged arbitrarily to meet spatial layout requirements and can be moved and extended in three dimensions, integrating component assembly and wiring connections. Flexible printed circuits can significantly reduce the size and weight of electronic products, meeting the demands of the trend toward higher density, miniaturization, and higher reliability.
