Reliability Failure Analysis Request Form
The FAR (Failure Analysis Request) is designed to verify a product problem and
determine corrective action through the evaluation of a small quantity. The
process begins with the customer contacting the Area Sales Office or the Customer
Return Services (CRS) group at (321)724-7400 or creturn@intersil.com. The
customer will be requested to fill out the FAR form completely in order for the
factory to understand the problem experienced by the customer and aide the
analysts in their efforts to determine the root cause of the failure and corrective
action. The CRS group will then assign a tracking number and give instructions as
to where to ship the parts along with the completed FAR form.

Problem Description-Detailed
description of the failure to
include pins, voltages,

versus expected:
Is this a known or repeat Issue
(Yes/No)
Failures Verified (Yes/No)
Y/N:
Qty:
Lot size on hold that could require a RMA.
Determines if this is an issue previously seen or identified on a
previous analysis for this customer.
Identifies if failures were returned with or without verification to
isolate the failure.
ABA verification consists of removing a suspect device from the
failing product and placing it on a known good product, along with
placing a known good device on the failing product. If not
performed on all units, then highlight in Verification Procedure.
ABA Performed (yes or No)
Describe Failure Verification
Procedures Used:
Schematics, test conditions,
waveforms, measurements
etc. attached (Yes or No)
Details of the customer application and test conditions are needed
to evaluate beyond ATE production test. Customer to provide as
much details as possible (i.e. schematics, test conditions,
waveforms, measurements, photos, etc.) to aid in the evaluation.
Special Requirements for HS Video (TWxxxx) products:
