NJ MET is an independent electronics laboratory providing, electronic testing, upscreening and counterfeit detection for electronic components.
“We need to constantly upgrade our testing to keep up and attempt to keep these parts out of the supply chain,” said Joseph Federico. “Electronic component counterfeiters are using increasing sophisticated techniques to replace markings on lower grade parts and relabeling them for military or aerospace use.”
NJ MET (http://www.njmetmtl.com) is adding the experimental marking permanency test from MIL-STD-750 (http://www.landandmaritime.dla.mil/
The component is suspended so that half of the device is in a solution of 1-Methyl 2-Pyrrolidinone and heated between 115-120ºC for between 2-5 minutes.
It is then required that the part and the bristle portion of a brush be completely immersed for 1 minute minimum in the solution. Immediately following immersion, the specimen is 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 marking should not smear or be removed. After the conclusion of the test, all devices will be placed under the microscopic camera and recorded for identification, disposition and permanent documentation purposes.
There are engineering specifications for the brush as well, Joseph Federico (http://www.josephfedericocliftonnj.com/
Closing adhering to this updated procedure is necessary to improve accuracy. Accuracy includes limiting the number of false positives. “With the right solution and aggressive enough rubbing, legitimate part markings could be discolored or removed,” Federico said.
