IPC has a task group that is working on developing guidelines for
     using and testing bar code labels.  This task group functions
     under the Assembly and Joining Committee of IPC.  The document
     the task group is developing is  IPC-7911,  which is titled
     "Guidelines for Using Self-Adhesive Bar Code Labels for
     In-process Tracking of Electronic Assemblies".  The current draft
     of this document focuses mainly on the testing of label materials
     to assess whether they will survive circuit board assembly
     processes and remain legible.  Copies of the draft are available
     from IPC.  The task group met at IPC Expo back in April, and the
     draft may be undergoing some significant changes based on that
     meeting.  The task group is also looking for new members.
     Contact me offline for additional information on anticipated
     changes or task group membership.

     Subject:  [TN] : Ink permanency Test and Adhesive Strength





Hi Technetters,

Could anyone advise me :-

1.  Is there any spec. for ink permanency test on the bar-code label.

2.  Is there any spec. to determine the adhesiveness or strength for
    the label which used for bar-code labelling.

Rgds,

Poh
