FA flow challenges • Package decapsulation & Electrical testing – Keep electrical functionality & provide IC access for analysis – Small package & large IC is a challenge • • • •
Mechanical stress induced by decapsulation (molding / leadframe) Package contact with PCB after decapsulation Dedicated low profile open top socket required for EMMI/TLS Repackaging strategy for FA not always considered ( + risk ).
FA tool : Laser stimulation • TLS (Thermal Laser Stimulation) - Powerful FA tool for analog - Need external symptom that a change due to Laser occurs. - Access to internal nodes to bypass “blocking” functions : Design For Analysis (DFA) approach VCC_PCB
FA tool : IR thermography • FA analysis issue for Power MOS : – High power testing on stand alone component – FA tools (TLS, EMMI) limited by top metal layers blocking information. – Backside FA (through silicon) means more invasive sample preparation
• IR Thermography – – – –
