DfR Solutions and Electrolube to Study Coating Defects
Beltsville, MD — DfR and Electrol- ube have planned to participate in a joint research study to examine the cracking defects of conformal coat- ings. A significant number of elec- tronic designs, driven by the explo- sive growth of automotive electronics and the Internet of Things (IoT), are incorporating conformal coatings to mitigate the risk of corrosion and en-
High-Torque Retention Knob From JM Performance Products
Fairport, OH — A new high-torque retention knob from JM Performance Products can boost the productivity of machining operations. The reten- tion knob is designed to reach deeper into the threaded bore of the tool- holder. As a result, all thread en- gagement occurs in a region of the toolholder where there is a thicker cross-section of material, resisting deformation.
vironmental test failure. However, incompatibilities be-
tween the coating, the design and the environment can result in cracks or tears in the conformal coating, conse- quently reducing or completely elim- inating the effectiveness of the coat- ing. This is especially true when using UV-cured coatings and per- forming thermal shock qualification testing. The joint study will involve a thorough, detailed investigation of over 3,000 samples, including artifi-
cial aging and characterization, over the course of six to nine months. DfR Solutions’ Sherlock Auto-
mated Design Analysis™ software is designed for analyzing, grading, and certifying the expected reliability of products at the PCB assembly level. Based on the science of physics of failure (PoF) or reliability physics, it is used by the electronics industry across all markets, allowing users to manage increasingly complex analy- ses quickly and efficiently.
The collaboration between DfR
Solutions and Electrolube is expected to produce results and data to give global electronics manufacturers the full, informed advantage of increas- ing the long-term reliability of their products.

CREATING TOMORROW’S SOLUTIONS
DRIVING TOMORROW’S e-NOVATION: SILICONE – MATERIAL OF CHOICE FOR e-MOBILITY APPLICATIONS.
Retention knob installed in toolholder.
When tightened, poorly de-
signed retention knobs can bulge the toolholder imperceptibly at the small end of the taper, preventing full con- tact and proper seating of the tool- holder in the spindle. This slows cut- ting speeds, affects tolerances and precision, shortens tool life and even increases power consumption. By combining the high-torque
retention knob with the correct torque, spindle contact with the taper is improved to close to 100 per- cent every time. This can be verified by simple six-step “touch off” test, which is available at the company’s website. More sophisticated measure-
ment of toolholder expansion (bulge) can also be taken using a taper
shank test fixture. Contact: JM Performance Prod- ucts, Inc., 1234 High Street, Fair-
