High welding current and temperature are unfavorable for welding parts. Excessive combustion of molten iron can result in the loss of some metal components, reduce welding strength and toughness, and cause deformation. In theory, 280° can be used; Below, but for normal use, it is recommended not to be lower than -20 degrees;, Not exceeding 80 degrees;. How to control temperature in production:

1. Due to the expansion of FPC caused by temperature and pressure during ACF crimping, the expansion rate of crimping fingers should be considered in the initial design of the circuit and compensated in advance;

2. It is best to add baking before drilling to reduce the expansion and contraction of the substrate caused by high moisture content during subsequent processing.

3. During the production process, try to maintain stable temperature and humidity at each workstation. When transferring between stations, especially for those that need to be exported, special attention should be paid to the storage conditions of the products.

4TheOf course, the completion of the product does not mean everything is fine. We need to ensure that the customer has no surface during subsequent use. It is best to bake it, dry the substrate of absorbed moisture during the manufacturing process, then use vacuum packaging, and guide the customer on how to store it.
