Thermal/ Mechanical Specifications and Design Guide
2.1.2.3.6 Orientation in Packaging, Shipping, and Handling
Packaging media needs to support high-volume manufacturing. Media design must be
such that no component of the socket (solder balls, contacts, housing, and so on) is
damaged during shipping and handling.
2.1.2.3.7 Pick and Place, and Handling Cover
To facilitate high-volume manufacturing, the socket shall have a detachable cover to
support the vacuum type Pick and Place system. The cover will remains on the socket
during reflow to help prevent contamination during reflow. The cover can withstand
260°C for 40 seconds (typical reflow/rework profile) and the conditions listed in
Appendix B without degrading. The cover could also be used as a protective device to
prevent damage to the contact field during handling.
Cover retention must be sufficient to support the socket weight during lifting,
translation, and placement (board manufacturing), and during board and system
shipping and handling. Cover design shall allow use of tool to remove the cover. The
force required for removing of the cover shall meet or exceed the applicable
requirements of SEMI S8-0999 Safety Guidelines for Ergonomics/Human Factors
Engineering of Semiconductor Manufacturing Equipment. The removal of the cover
shall not cause any possible damage to the socket body nor to the cover itself within
the cover durability limit.
The pick and place cover designed shall be interchangeable between socket suppliers.
Note: The cover will remain on the socket with intent to continue providing contact protection
during the ILM installation. Once the ILM with its cover is installed, the socket PnP
cover must be removed to prevent damage to the socket contacts.
