夹子和导线架连接

In power electronics packaging, clip-attach and lead frame attach are two methods used to bond pre-fabricated copper frames, enabling efficient internal and external interconnections. Clip-attach typically connects the top of the semiconductor die to the substrate, while lead-frame attach extends beyond the package to create external electrical connection terminals. The choice of bonding material is crucial for enhancing yield and overall performance.

Cutting-Edge Solutions from Indium Corporation

高可靠性

Enhance the reliability of your power electronics by choosing the optimal material. Indium Corporation provides solutions ranging from InFORMS® and high-reliability alloys to sintering materials.

无助熔剂焊接

By utilizing preforms and InFORMS® specially designed for formic acid reflow processes, these flux-free solder systems eliminate the need for post-reflow cleaning.

可控粘合线厚度

InFORMS® reinforced preforms employ Indium’s matrix standoff design to consistently achieve a minimum bond line thickness (BLT), preventing stress concentration on the die surface and enhancing solder joint reliability.

Wide Alloy Selection

Indium Corporation offers a broad range of alloy options—in both Pb-based and Pb-free compositions—suitable for low- and high-temperature melting applications.
