Development and Application of Electroplating Copper Products with Low or Zero Internal Stress

Shinhao Material LLC has developed several kinds of stress-free products, such as SC-5 and SC-6, which can meet the requirements of matte copper and bright copper respectively. The internal stress after electroplating is less than 3 MPa. After anneal or aging, the internal stress is approximately zero. This is mainly due to the unique role of electroplating additives developed by Suzhou Shinhao Material LLC, which makes the electroplated copper form a distinctive microstructure, so that the internal stress of electroplated copper is very small and can be competent in the field with high internal stress requirements, such as panel level fan out packaging, LED panel, wafer electroplating, etc.
