John,
I agree with Ted that this can and does happen just as he explained.  I see
no problem with changing the wording to allow the user (I prefer customer)
and supplier to agree on what is allowed.

Subject: [IPC-600-6012] Proposed Change to Acceptance Criteria for Lifted
Lands


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
