ply network. Therefore, it is critical to understand the quality manage- ment systems of your independent partners. Know Your Source According to Thomas, the mantra in his industry to eliminate risk is “know your source.” To accomplish this, leading independent distrib- utors invest millions to manage global supply networks, rate/prior- itize suppliers, establish preferred supplier relationships and acquire the latest inspection equipment and utilize effective Quality Management Systems (QMS). “Over time, companies like ours have developed a very complex method of identifying and eliminating risk,” says Thomas. “That includes knowing how to inspect and test components that come in to our facility, but also goes well beyond that.” It also means analyzing and inspect- ing sources with an investigative diligence. What path did the parts take to get there? Who is the man- ufacturer and how is that relevant? Where was it made? How was it shipped and packaged? Is demand of a component strong enough to make its availability viable? Only thorough examination and assessment of all these factors, in conjunction with traceability, can the risk be truly mitigated. “When we purchase components like MLCCs, for example, we are purchas- ing from a direct source,” explains Thomas. “That could be a regional or foreign distributor, an OEM partner or direct from the factory.” To verify the chain of custody, traceability documentation can be provided that identifies the name and location of all the supply chain inter- mediaries from the part manufactur- er to the direct source of the product. If this traceability is unavailable, a risk mitigation plan is required. Finally, visual inspection, testing and physical analysis are performed on all incoming products. Purchasing Power The truth is that many of the shortag- es were predicted some time ago. As a result, leading independent stock- ing distributors like Classic Compo- nents have spent the past few years engaged in a long-term strategy of identifying, and investing in, directly sourced critical electronic compo- nents. 6 TEC Magazine • March 2019
