The costs of the testing should not increase when the voltage needs to be reduced. We make cables for military and commercial applications. For the pull strength test, the PCB is fastened onto the jig at a 45°angle, and the sample component accurately aligned under the small test hook using the X-Y table. When a cable experiences elastic deformation, it absorbs the tensile energy, elongates, then returns to its normal shape once the force is no longer applied. Note: Available only to IPC Certified IPC-7711/7721 Instructors (CIT). The IPC-620 Standard prescribes industry’s best practices and requirements for the manufacture of cable and wire harness assemblies. When the voltage is first applied, the current usually peaks and then, due to humidity that might be dried out by the energy of applied voltage and something called "dielectric absorption", it trends lower over time. They are provided in an electronic format that permits users to edit the tables to add user-specific criteria. IPC/WHMA-A-620, Section 19.6.1 states that a manufacturer’s documented process Certificate Validation You can validate a certificate here. . Sign up for our newsletter today. ... For example, IPC A-620 states that a crimp should account for no less than 60% of a wire’s tensile strength, unless otherwise stated. For example, IPC A-620 states that a crimp should account for no less than 60% of a wire’s tensile strength, unless otherwise stated. The point where the curve began to flatten is where it started to experience plastic deformation, culminating in the peak of the graph around 5.6lbF and approximately .175 inches of travel. A 50N loadcell was employed to gain the best accuracy for low force measurements. Contents Online: Exams f or ALL IPC-7711/7721 CIS Modules.
