Mechanical Requirements
 
 
mPGA604 Socket 
13 
Mechanical Design Guide 
3.7 
Socket/Package Translation During Actuation 
The socket shall be built so that the post-actuated package pin field displacement will not exceed 
1.27 mm. Movement will be along the Y direction. No Z-axis travel (lift out) of the package is 
allowed during actuation. 
3.8 
Orientation in Packaging, Shipping and Handling 
Packaging media needs to support high volume manufacturing. 
3.9 Contact 
Characteristics 
3.9.1 
Number of contacts 
Total number of contacts: 603. 
Total number of contact holes: 604. 
3.9.2 Base 
Material 
High strength copper alloy. 
3.9.3 Contact 
Area 
Plating 
0.762 µm (min) gold plating over 1.27 µm (min) nickel underplate in critical contact areas (area on 
socket contacts where processor pins will mate) is required. No contamination by solder in the 
contact area is allowed during solder reflow. 
3.9.4 
Solder Ball Attachment Area Plating 
3.81 µm (min) Tin/Lead (typically 85+-5Sn/Pb balance). 
3.9.5 
Solder Ball Characteristics 
Tin/Lead (63/37 + 0.5% Sn). 
3.9.6 Lubricants 
For the final assembled product, no lubricant is permitted on the socket contacts. If lubricants are 
used elsewhere within the socket assembly, these lubricants must not be able to migrate to the 
socket contacts. 
3.10 
Material and Recycling Requirements 
Cadmium shall not be used in the painting or plating of the socket.
