What problems can arise if the flux residue is not removed?
The purpose and reason for cleaning flux is to prevent the occurrence of electrical and physical troubles. The ionic components of flux residues can cause ion migration under high humidity, leading to metal deposition between electrodes and resulting in short circuits. Additionally, when halogen ions are present under high temperature and high humidity, they can form halogen compounds that become brittle and collapse. Furthermore, if flux residues adhere to contact points such as connectors, it can cause connection failures. 【Troubles to Prevent (Partial List)】 ■ Decreased insulation reliability ■ Corrosion ■ Connection failures ■ Leaks or shorts due to residual solder balls ■ Reduced bonding strength in wire bonding *For more details, please refer to the related links or feel free to contact us.
