Te following are some useful things to consider during planning your counterfeit component strategy: • A simple approach to minimise counterfeit components passing through goods receipt to pro- duction is to create a component reference database.
Reference
components and images of known good components can be used for future comparison. Reference component details should be obtained when a component is known to be going obsolescent, experiences long lead times, becomes difficult to obtain or is found to be in circulation as a counterfeit product
• Where components are being used in existing products or being considered in new products that are single source, on long lead times they should be added to the component database. Where components are
considered to
be high risk, are knowingly pur- chased from a new source or the supplier has not been previously qualified, reference samples must be obtained for review and pos- sible testing
• A golden board assembly is oſten held in manufacture as a reference for build quality or as an inspec- tion reference and could be used by goods receipt staff. A refer- ence source/photo guide should be compiled of existing qualified manufacturers’
logos, packing
labels, SMT reel labels and outer packing labels for use at goods receipt inspection
• Select and appoint an indepen- dent laboratory to conduct com- ponent testing when specialist tests may be required for indepen- dent verification. Provide an open order with the company so that urgent testing is not held up with internal paper work problems.
cannot check all
components at goods inwards, even if they wanted to.
Bob Willis will be running the “IPC & NPL Process Defect Clinic” live at APEX 2011 in Las Vegas along with four training workshops,
one covering counterfeit
components and practical testing of parts. Join members of the NPL Team for free advice on process rejects and failures or go to
