Leading Ag-Sintering Technologies from Boschman

Boschman has been leading the way in sintering technologies since 2014 when they introduced the groundbreaking Sinterstar Innovate-F-XL. The company, based in the Netherlands, specializes in advanced transfer molding and sintering systems. NDC International represents Boschman Advanced Packaging Technologies in the Eastern United States.

Ag-Sintering Improves Performance & Longevity

New technologies have been developed to meet demands for devices with longer life and greater reliability. Electronic devices continue to become smaller and operate at higher power densities and temperatures requiring new approaches in manufacturing. Boschman’s latest sintering technologies address this need offering void-free, strong bonding with high thermal and electrical conductivity. In comparison to traditional solder methods, sinter bonding improves both the performance and longevity of devices. It can decrease the junction temperature (Tj) of your device up to 100℃. In the properly managed sinter process, the silver material changes in form from powder to a solid structure resulting in a more reliable bond.

In addition, Boschman offers in-depth knowledge and experience having supported many customers with sintering solutions over the past decade. Plus, their unique patented silicon-free dynamic insert technology (DIT) guarantees equal pressure for multi-die applications.

Boschman’s Ag-Sintering Products

Boschman’s silver (Ag) sintering solutions fall into two categories. For low-volume production, R&D and prototyping they offer the semi-automatic Sinterstar Innovate series. The Sinterstar Auto and Inline series address the need for medium-volume and high-volume production.

Advantages include:
• Closed loop precise pressure control and monitoring.
• Pressure applied only on areas where required.
• Extremely long life-time of tooling resulting in very low running costs.
• Enabling highest density tools with interspaces down to 400µm.
• Largest available effective sinter area of 350x270mm, providing a high UPH.
• Supporting large variation of geometries, including clips.
