TCB
TCB (Thermal‑Compression Bonding)
Core Value
TCB (Thermal‑Compression Bonding) is a critical interconnection technology within semiconductor advanced packaging. It is mainly adopted for high‑precision interconnection between chip‑to‑substrate and chip‑to‑chip, performing dual functions of electrical connection and heat conduction. It directly governs interconnection density, transmission efficiency and long‑term reliability of packaged devices, and is widely used in high‑end chips, sensors, optical modules, automotive electronics and other fields.
Focusing on supporting materials for TCB, Huaqing precisely meets requirements for high precision, high heat resistance and high reliability. Premium materials and professional technologies consolidate the core competitiveness of customers’ products.
Core Significance
Supporting materials form the fundamental foundation for TCB to realize high‑precision interconnection, and their quality directly determines bonding performance and device reliability.
Suitable bonding solders, thermal‑conductive auxiliaries and buffer materials satisfy core requirements of TCB under high‑temperature and high‑pressure bonding conditions. They enhance adhesion and electrical conductivity of bonding interfaces, optimize heat‑transfer efficiency, and prevent issues such as poor bonding contact, interfacial cracking and signal attenuation. This lays a solid foundation for stable TCB interconnection and fundamentally reduces operation‑maintenance and rework costs.
Industry Challenges
As semiconductor packaging evolves toward high density, miniaturization and high power, the application of TCB technology faces multiple practical challenges
Bonding‑accuracy requirements keep increasing, imposing strict demands on uniformity and melting‑point stability of supporting materials. Conventional materials cannot fulfill the requirements for fine‑pitch and high‑precision bonding.
Interfacial oxidation and insufficient bonding strength may occur during high‑temperature high‑pressure bonding, shortening device service life.
High‑end TCB supporting materials (e.g. dedicated bonding solders and buffer auxiliaries) are heavily import‑dependent, leading to unstable supply chains and delayed responses for customized adaptation.
