High welding current and high temperature will not benefit the welding parts. Excessive burning of molten iron will lose some metal components and reduce the strength and toughness of the welding joint, resulting in deformation.Theory within 280 ° can, but normal use proposal should be no less than 20 ° - is not higher than 80 °.How to control the temperature in production:

1. Due to the expansion of FPC due to temperature and pressure during ACF compression, the expansion rate of the compression finger should be taken into account in the initial design of the circuit for pre-compensation treatment.

2. It is better to bake before drilling, so as to reduce the expansion and contraction of the substrate during subsequent processing due to the high content of moisture in the substrate.

3. Keep the stability of temperature and humidity in all stations as far as possible in the production process, and transfer between stations, especially those that need to be produced outside, and the conditions of product storage shall be paid special attention to.
