Durable 3M 2256-9357-0A-2401 BGA Burn-In Socket with Excellent Airflow and Balanced Contact Forces
3M Textool BGA Test & Burn-In Sockets
Product Overview
3M Textool BGA Test & Burn-In Sockets, with a 1.00 mm pitch, are designed for reliable testing and burn-in applications of Ball Grid Array (BGA) devices. These open-top sockets feature a double-beam, normally-closed contact design that provides balanced, opposing forces to the solder ball, minimizing shear stress and producing only slight indentations with minimal ball deformation. They offer excellent airflow around the device and include a retractable locating guide for easy board mounting, accommodating hundreds of leads. Compatible with most robotic handlers while allowing for easy manual operation, these sockets accept package body sizes up to 29 mm square with a maximum matrix of 27 x 27. They are RoHS compliant, ensuring adherence to environmental regulations.
Key Features:
- Double-beam normally-closed contact for balanced forces and minimal solder ball stress.
- Contact tips touch ball above its center plane for reduced deformation.
- Excellent airflow around the device.
- Retractable locating guide for easy board mounting.
- Compatible with robotic handlers and manual operation.
- RoHS compliant.
