Colleagues,

IPC would like a task group disposition on the following comment for the IPC-6012 B Revision effort.

Ted Edwards of Dynaco Corporation has proposed rebuilding paragraph 3.3.4 in the IPC-6012B 2nd Working Draft relative to allowances for Lifted Lands to read:

When visually examined in accordance with 3.3, the finished board shall not exhibit any lifted lands unless agreed upon between user and supplier.

Reason for Recommended Change:  On thick boards with thick plating requirements, if a HASL finished is used there almost always exists lifted lands and this statement would mean that they would all have to be scrapped.

Your reply is appreciated.

Regards,

John Perry
IPC
