Fraudulent box Labeling mistakes
A missing icon could mean the label is fake,
but the 0335 date code on a brand new
box is a clue…
3
Labeling Misspelling
Misspelled words tell you this bag was not
made in a legal factory.
It is a fake
4
Labeling Misspelling
This label has a misspelled company
name.
You may assume that Motorola did not
print this
5
Labeling Logos and Fonts
The Elantec label on the top was printed and
then cut out and pasted above the large label.
Notice the difference between the fonts used
in the top and bottom “Elantec” words
6
Part marking Detecting fake ink markings
Example of a component that has failed
the marker permanency test
7
Marker permanency testing Requirements
A mixture of 3-parts mineral spirits and 1-part alcohol is used for testing a
re-marked component
Mil-STD-883 (method 2015.13) requires markings to withstand a swab
wash without fading
Mil-STD-202 (method 215) provides for a similar test
9
Marking quality Ink over laser marking
Notice the white ink stamped
part number on top, and the
previous laser cut part number underneath
10
Black-topping How it’s done
TYPICAL SURFACE MOUNT COMPONENT
Look for machine scratches on the leads to verify they are not reworked
Frequently, a reworked component will have the top surface removed and re-coated to hide scratches - known as “black topping”
If top surface has been removed, the pin-1 dimple will be
ill-defined and grainy
11
Marking quality Laser marking on top
A top surface without a falsetop coating to
hide sanding marks
12
Marking quality Grainy texture
This is a remarked
component with a false top
coating.
Notice the grainy texture and the pin-1 dimple is not smooth and
shiny
13
Marking quality Smooth surface
This is a good part.
Notice the smooth bottom
surface of the circular area &
the sharp letters in the word
“Korea”
14
Marking quality False coating washed away
Left of the line has been
washed with acetone to
remove the false coating.
You can see the
original part underneath
15
Marking quality False coating spilled into relief area
Notice the false coating material
in the bottom of the circular area.
This doesnot belong
there. This part is modified
16
Marking quality False coating spilled down the side of the component
The material running down the side is the
“false top” coating material
used by the counterfeiter to
cover the scratches left by
removing the old part number
17
Removing false top coating with an acetone wash
Acetone is not used for the marker test
The false top coating has been removed to show the
original surface
The fake coating comes off on the Q-tip when an acetone wash is used
18
Re-worked component leads A good part looks like this
This is a good part. Notice the copper showing on the lead tips. Also notice the shiny scratches on the inside of the leads. These scratches are left there when they are bent
19
Re-worked component leads A re-worked part
This is a part that has been reworked
illegally.
Notice there is no copper showing on
the lead tips and the shiny areas that
should be on the lead curves are filled
in with solder
20
Used parts One sure sign
This a used part pretending to be a
new part.
The round circular area on each lead is
caused by the part having been plugged
into a circuit for a very long time
21
Used parts Re-coated leads with impurities
The two pin holes seen on the sides of this
component lead are caused by a rework
program to recoat the lead.
The dimples are caused by impurities -- never
seen when coming from a factory
23
Component comparison Different dies/stamps and country identification
Square holes
Different country of origin
Round holes
