Joseph Federico, NJ MET VP, Announces Additional Marking Permanency Test for Electronic Components
Joseph Federico, Vice President and Director of Operations at NJMET, announced this week that NJMET will begin performing an additional marking permanency test at its Clifton, New Jersey laboratory.
The objective of this test is to evaluate an electronic component’s marking permanency. The new test is performed by following an experimental portion from MIL-STD-750 and 883 that uses a solution of three parts mineral spirits with one part alcohol. To perform the test properly, it is suggested to use a brush with a handle made of a nonreactive material. The specification states that the brush shall have three long rows of hard bristles, the free ends of which shall lie substantially in the same plane. The brush shall be used exclusively with a single solvent and when there is any evidence of softening, bending wear, or loss of bristles, it shall be discarded.
According to the procedure in the specification, one dips the brush into the solution immediately following immersion of the component Then, the specimen shall be brushed with normal hand pressure (approximately 2 to 3 ounces) for ten strokes on the portion of the specimen where marking has been applied.
After this process, the markings should not smear or be removed. After the conclusion of the test all devices should be placed under a microscope camera and recorded for identification, disposition and future historical documentation. Results from this test are added to the final report for the devices.
If you have any questions about this new marking permanency test, the Mission Imposter Counterfeit Electronic Component Detection Program or any of the test services provided by NJ MET, please contact Joseph Federico at (973) 546-5393 at their Clifton, New Jersey headquarters or visit their website at http://www.njmetmtl.com .
