Chisel test

This innovative process looks promising as a means of measuring adhesive strength on MID because it is eminently suitable for very thin coatings. A microchisel is used to scan the topography of the conductor. The peeling chisel is then set to the

Chisel. Chisel testing is a quick, qualitative technique that is widely used to determine the soundness of explosion-welded metal interfaces. A chisel is driven into and along the weld interface, and the abiUty of the interface to resist the separating force of the chisel provides an excellent quaUtative measure of weld ductihty and strength. 

The structure of energy makes the emergence of life inevitable if the proper reaction conditions prevail. This, the determinist s clarion always sounds true because its score is chiseled into the structure of energy manifest in atoms. It also is a useful sound for it tells us that, if we should learn how to get to another earthlike planet, our test for life should be based upon the very principles that led to life on this planet. 

Tests of an oil composition in the presence of synthesized piperylene bis- tetrasulfide were performed on twenty chisels of drills under the conditions of the Far North.

Miscellaneous tools. Pressure gauge, magnetic pickup tool, multimeter (to test voltage, resistance, and amperage), punches, chisels, files, pens, tape, pry bars of various sizes, wire stripper, wire brush, oil pan, funnel, hacksaw, rags, and a couple of good flashlights (because one will inevitably be broken...). 

As described in Section 6.4.1.2, it is also possible to use shear testing to determine the adhesive strength of the metallization on MID [175]. An alternative to shear testing is to use a hooked chisel for pull-testing the legs of components and wire bonds. This can often be accomplished using the same system technology. 

It was noted that the penetration by the test probe in the bed-of-nails tester resulted in less penetration into the immersion Ag as compared to penetration into the Sn-Pb HASL finish, as shown in Fig. 77(a). A higher spring force and a three-sided chisel probe were chosen to improve...
