Dummy Components Provide Low-Cost Production Validation


By Russell Kido, Sales Manager, Practical Components, Inc. D


ummy components are me- chanical samples that are the form and fit of real production


components, but without the live die inside.


Practical Components is an in-


ternational distributor of mechanical IC samples, or dummy components. The company offers factory-manufac- tured dummy components that are virtually identical to their live coun- terparts. The same manufacturers that


create the live components make these dummies exactly the same, but without the expensive live die. Prac- tical Components distributes compo- nents for most major manufacturers and is the exclusive distributor of dummies for Amkor Technology, one of the world’s largest providers of contract semiconductor assembly and test services. Practical Components has a


team of dedicated electronics indus- try professionals, offering value pric- ing, on-time delivery and excellent service to customers. The company’s team is ready to provide project as- sistance in the areas of technical component knowledge, drawings, component land patterns, and PCB practice kits.

during reliability testing, tempera- ture profiling and vibration testing to gather data without using expensive

Who Uses Dummies? Dummy components are very


important to customers during any kind of reliability testing, tempera- ture profiling and vibration testing, as well as many other tests to repli- cate live components. This allows the customer to gather similar data, without using their expensive pro-


live components. Many OEMs, CMs, solder paste,


aerospace, military, medical, train- ing, and manufacturing companies use dummy components, as well as technical schools, high schools and universities. Practical Components uses a “dummy die” inside the components


processes, these components exhibit nearly identical characteristics as those of live components. Besides R&D and testing, dum-


mies can be used to evaluate, validate and qualify different types of equip- ment, such as pick-and-place, reflow ovens, stencil printers, cleaning, wash- ing and rinsing, rework, etc. These parts can be used for comparison test- ing between tin-lead and lead-free sol- der, between different solder pastes, types of fluxes, underfills, conformal coatings, used for destructive testing


Cpk testing, or to validate production lines when moving the line or before purchasing equipment. These dummy components can


also be daisy chained. When placed on- to a matching test board with the daisy chain pattern, they can be probed to test for continuity and proper place- ment. This allows the user to perform tests, before using expensive real pro- duction components. The benefits are very low cost, when compared with us- ing live components, and obtaining the same results during testing.
