We have thick boards plated up and don't have lifted lands.  It depends on the material and design.  I would like the paragraph to stay the way it is.  If someone is okay with lifted pads and it is a design issue it can go on their drawing.

Lif ted Lands


Hello John. Does it realy need to be stated "agreed upon between user and supplier"? In my opinion "agreed upon...." is a part of "Approved PB Procurement Documentation" see Section 3.5 in -6011.

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
