Insertion-based connector terminals create significant challenges.

Obsolete Technology Challenges Addressed:

• Complex multi-factor analysis required. (material, friction, thickness).
• High-precision required, costly manufacturing.
• Expensive consumables and assembly defects
• Incorrect power setting of the equipment (over 120 N) leads to breakage of an expensive pin
• Unstable connection which leads to further unstable operation of the whole unit
• Extreme tolerance sensitivity, causing misalignment or pin slippage in high-current circuits.
• Inclination-based scrap due to imperfect connections, increasing production costs.

SM Contact has redefined connection technology with its patented O-PIN solution, eliminating the pain points of traditional press-fit and DBC assembly.

Unlike conventional connector terminals, O-PIN technology leverages high-precision splice crimping for superior electrical and mechanical performance in IGBT modules.
Our innovative design delivers simpler installation, superior reliability, and significant cost savings – all while maintaining flawless electrical contact. No more expensive precision components or complex mating processes – O-PIN ensures stable connections with unmatched ease, reducing defects and production costs.

Bandolier Packaging – Ideal for automated assembly processes.

The connectors are delivered in a continuous strip, enabling smooth O-Pin Jig manipulation and indexation, followed by DBC assembling, Reflow soldering, and final Module release—without manual handling.
This format minimizes downtime and ensures precise positioning every time.

The supply of O-pin already including interface surface connectivity for DBC assembly, permits to manage overall inclination of pin tip (max inclination+- 1º) better in unique process, rather than accumulating errors from sleeve assembly and insertion processes.
