Markings
There are three markings on the socket:
• LGA1156: Font type is Helvetica Bold - minimum 6 point (2.125 mm).
• Manufacturer's insignia (font size at supplier's discretion).
• Lot identification code (allows traceability of manufacturing date and location).
• Manufacturer's insignia (font size at supplier's discretion).
• Lot identification code (allows traceability of manufacturing date and location).
All markings must withstand 260°C for 40 seconds (typical reflow/rework profile)
without degrading, and must be visible after the socket is mounted on the
motherboard.

Component Insertion Forces
Any actuation must meet or exceed SEMI S8-95 Safety Guidelines for Ergonomics/
Human Factors Engineering of Semiconductor Manufacturing Equipment, example Table
R2-7 (Maximum Grip Forces). The socket must be designed so that it requires no force
to insert the package into the socket.
