ODU MAC

Technical ArticleAfter 500 or at most 1000 insertion/withdrawal cycles, the failure probability rises sharply. A remedyfor this is to use special test adaptors with special springwire flat contacts, such as ODU has developed.These contacts tolerate several hundred thousand insertion/withdrawal cycles with a very high degreeof reliability.ODU springwire socket for the connectionof flat contacts (for example, 0.8 x 2.8 mm).The socket permit many hundred thousandinsertion /withdrawal cycles.Figure 2Likewise, ODU has developed special springwire contacts for very high insertion /withdrawal cycles forsquare pins (for example, 0.64 x 0.64) and for round pins (for Ø from 0.7 to over 10 mm).ODU springwire sockets for the connectionof round contacts (from Ø= 0.7 to over 10 mm)and square contacts (for example, 0.64 x 0.64).Under ideal conditions, over 1 million insertion/withdrawal cycles are possible.Figure 32. The interfaceBasically, it is possible to connect the product and insert the values directly into the test computer. Howeverit can very quickly be seen that it´s expedient to provide an interface (a connector) between the testpiece and the computer. This can be explained by an example.Example: Testing car radios – an absolutely typical case!Carrier rack for test line with test piece (car radio)and ODU-MAC (socket part)Figure 4ODU Steckverbindungssysteme GmbH & Co.
