Hi Jiang,
Advanced Interconnect has .8mm BGA sockets in their catalog.  They might be able to give you the names of companies that are using them.  I am using (169) .8 mm BGA's but have not socketed them...... yet.

Subject: [TN] 0.8mm pitch BGA socket

Hello Technetters,
 
Does anyone has experience using 0.8mm BGA socket that can be easily soldered on board and give a reliable contact? We have a unsuccessful try and are looking for recommendations.
 
Thanks in advance.
