Detecting fake materials Key clues

2

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

8

Marking quality Poor marking

Look for smeared ink.

It could be a fake component

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

22

Re-coated leads Re-coated leads showing prior use

23

Component comparison Different dies/stamps and country identification

Square holes

Different country of origin

Round holes
