2. IDEA-STD-1010-A
Independent Distributors of Electronics
Association (2006)
Recognises and complies with IPC-A-610
Attempts to determine with high confidence
that parts under examination indicate new
condition, and that they have been stored,
handles and packaged acceptably.
4. Product Inspection
Handling
Neat area, no food, drink or smoking
Minimise handling
Use gloves
No creams especially silicone based
Don’t stack components
Always assume ESD sensitive
Train operators in ESD issues
5. Product Inspection
Moisture Sensitivity (refers to
IPC/JEDEC J-STD-020)
Floor life not exceeding 30.C & 60%RH
Shelf life
Drying
Dry pack
Humidity indicator card
Oxidation risk
6. Product Inspection
Photographing parts
Inspector approach/training
Non conforming until indicated as
conforming
Application of statistics
RoHS & appearance issues
7. Product Inspection
Dates codes – watch for mixed date
codes
Lot codes – does the code on the part
match the code on the packaging
Co-Planarity - to JEDEC JESD22-B108,
in dead bug position on ESD safe block
10. Testing - Remarking
3 parts white spirit to 1 part alcohol on
a cotton wool bud.
MIL-STD-883 requires parts to
withstand this.
11.
12. Testing – Evidence of
resurfacing
Acetone on cotton wool bud
Removes most “black-topping”
Counterfeiters have become aware
Mould cavities should be bright
Acetone often removes legitimate inks!
13. From the original manufacturer
(in a round about route)
Faulty die do not get scrapped
Faulty end product does not get
scrapped
Over-runs
Old stock gets relabelled
Upgrading
Non RoHS compliant product is
relabelled
14. From another source
Alternative supplier product relabelled
Any similar package but without a die
Any similar package but wrong die
relabelled
Fake labels for passives
From the dump and reworked
Piracy
15. Possible signs of problems
Bent leads
Contaminated leads
Misaligned leads
Re-tinned leads
Oxidised leads
Poor wetting on leads
Corrosion on leads and metal parts
16. Possible defects
Scratched legs or body
Fingerprints
Exposed bare metal on leads
Chipped corners
Exposure to excessive heat
Evidence of previous part insertion into
a socket
17. Possible defects
Debris and foreign bodies on parts
Evidence of re-tinning
Evidence of re-balling
Excessive solder
Moulding marks are different
Evidence of remarking
Evidence of resurfacing
18. Possible defects
Logos not quite right
Inconsistency of date and lot codes
Different texture between parts
19. Visual & Light Microscope
Inspection
Incorrect labelling
Evidence of marking
removal by solvent
or sanding
Co-planarity, even
number of leads
Poor or incorrect
moulding
