Detecting fake materials

Detecting fake materials

Key clues


Fraudulent box

Fraudulent box

A missing icon could mean the label is fake, but the 0335 date code on a brand new

box is a clue…

Labeling mistakes


Labeling

Labeling

Misspelled words tell you this bag was not made in a legal factory.

It is a fake

Misspelling


Labeling1

Labeling

This label has a misspelled company name.

You may assume that Motorola did not print this

Misspelling


Labeling2

Labeling

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

Logos and Fonts


Part marking

Part marking

Example of a component that has failed

the marker

permanency test

Detecting fake ink markings


Marker permanency testing

Marker permanency testing

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

Requirements


Marking quality

Marking quality

Look for smeared ink.

It could be a fake component

Poor marking


Marking quality1

Marking quality

Notice the white ink stamped part number on top, and the previous laser cut part number underneath

Ink over laser marking


Black topping

Black-topping

Frequently, a reworked component will have the top surface removed and re-coated to hidescratches - known as “black topping”

TYPICAL SURFACE MOUNT COMPONENT

If top surface has been removed, the pin-1 dimple will be ill-defined and grainy

Look for machine scratches on the leads to verify they are not reworked

How it’s done


Marking quality2

Marking quality

A top surface without a falsetop coating to hide sanding marks

Laser marking on top


Marking quality3

Marking quality

This is a remarked component with a false top coating.

Notice the grainy texture and the pin-1 dimple is not smooth and shiny

Grainy texture


Marking quality4

Marking quality

This is a good part.

Notice the smooth bottom surface of the circular area & the sharp letters in the word “Korea”

Smooth surface


Marking quality5

Marking quality

Left of the line has been washed with

acetone to remove the false coating.

You can see the original part underneath

False coating washed away


Marking quality6

Marking quality

Notice the false coating material in the

bottom of the circular area.

This does

not belong there. This part is modified

False coating spilled into relief area


Marking quality7

Marking quality

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

False coating spilled down the side of the component


Removing false top coating with an acetone wash

Removing false top coating with an acetone wash

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

Acetone is not used for the marker test


Re worked component leads

Re-worked component leads

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

A good part looks like this


Re worked component leads1

Re-worked component leads

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

A re-worked part


Used parts

Used parts

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

One sure sign


Used parts1

Used parts

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
