Both HTOL and LTOL testing are aimed at accelerating the aging process of integrated circuits under extreme temperature conditions, in order to quickly identify potential failure modes.

In the field of reliability testing, there are many common English abbreviations and their corresponding descriptions.

Atomic Layer Etching (ALE) is a high-precision etching technique that can be regarded as the reverse process of Atomic Layer Deposition (ALD).

The heat dissipation circuit of the power module is through the chip DCB、 The copper substrate, heat sink, welding layer, and thermal grease layer are connected in series.

The reliability evaluation of TFT (Thin Film Transistor) is a comprehensive evaluation process, which is an important link to ensure the quality and stable performance of electronic products such as TFT LCD screens.

CP testing refers to the electrical and functional testing of each chip unit (Die) directly on the wafer before it is cut and packaged.

Integrated circuit testing is a crucial step in ensuring chip quality, with the two main types of testing being CP testing (Chip Probing) and FT testing (Final Test).

The role of probe cards in integrated circuit testing is crucial. It is not only the interface between ATE and wafer, but also an important tool to ensure chip yield and quality.
