Abstract: According to principles of the disclosure as explained herein, selected leads are electrically connected through metal strips to the lead frame until the end of the manufacturing process. The lead frame is grounded through the manufacturing process to prevent any ESD event from causing damage to the protected leads. In the final singulation step, the leads are electrically isolated from each other and from the lead frame, thus maintaining protection from a potential ESD event up until the final package singulation step.
