Plastic deformation can be further divided into. It has a built-in force gauge that requires the operator to pull-back with a specified force in order to move on to the next wire. Cirris.com will store cookies on your device for login, form submissions, and analytics. This tool is IPC/WHMA-A-620 Class 2 and RoHS compliant SCOPE ... Molex web site for the Quality Crimp Handbook for more information on pull testing. IPC/WHMA-A-620 Training for Instructor. Conductive connector shells and unused contact positions shall be included where a risk of a short exists.”. student training materials (previously called student handbooks) They also increase the chance of an intermittent or latent defect in the form of a short. Cirris' Pin-Sight tool guides operators to insert wires into the correct cavity. The costs of the testing should not increase when the voltage needs to be reduced. These certification programs, built around IPC standards, developed and approved by industry, are delivered in a classroom setting by IPC certified trainers. When testing at 1000 VDC the gap must be larger than .15mm, (.006"). In 2011, Cirris helped propose changes to the test section for the next edition of the A-620 standard (Rev B released in October of 2012). , in which force is applied until the terminal separates from the wire or the wire itself breaks. (A-620, section 1.8). IPC and the Wire Harness Manufacturers Association (WHMA) continued to work together to develop this significant update. Section 19.5.3, Electrical Test Methods – Dielectric Withstanding Voltage (DWV): “On points to be tested, harnesses shall […]be tested for DWV for all isolated continuity paths as defined in continuity tests. The customer required the pull test to reach a maximum force of 20N for the connections to pass. We are not aware of any research or proof that the insulation used in good assemblies can be degraded by high voltage during brief applications in the IR and DWV tests. Vehicle Cables. Materials authorized for reproduction by the user will be so identified and provided by IPC in ____ format, e.g. Increased corporate focus & certifications Compulink has an established full-time training position for the IPC-620 workmanship standard for cable and harness assembly. Longer times have better chances of detecting faults. They are pin-pull test, ball-pull test and ball-shear test. As described earlier, 5.6lbF is the cable’s Ultimate Tensile Strength at the top of the graph where the cable presumably went from experiencing uniform plastic deformation to non-uniform plastic deformation. These tables are from IPC/WHMA-A-620 Revision B Chapter 19 Testing. The IPC-A-620 training for instructors (CITs) is a program centered on the IPC-A-620 Requirements and Acceptance for Cable and Wire Harness Assemblies, the well-recognized document for wire and cable harness acceptance criteria.This standard, developed in conjunction with the Wire Harness Manufacturers Association or WHMA for short, defines the … Typically, the end-use environment would not cause failures. 620 Wire Harness Assembly (Theory) Workmanship standards and inspection criterion for cable and wire harness assemblies. Certified IPC Specialist training programs will train, test and certify in the correct application of the criteria for all product classes. The IPC-620 Standard prescribes industry’s best practices and requirements for the manufacture of cable and wire harness assemblies. This ISO certification awarded... read more, In a fiercely competitive cable manufacturing market, it’s essential for any manufacturer to maintain both the resources and the... read more, Crimp joints are permanent electrical connections between a conductive wire and a crimp terminal. Cable Test Capabilities: Hi-pot Tester. When a cable is subjected to a pull test, one end is fixed at the bottom while the other end is attached to a movement force, typically along a linear axis. As an IPC authorized training facility, ACI Technologies provides training opportunities for students wishing to become certified at a level of proficiency which enables the graduate to train others. This is a comprehensive, 3-day, lecture and exam course that teaches students the accept/reject criteria in the IPC-A-620, for all three classes of cable and wire harness assembly. With creepage distance >2 mm the likelihood of finding near-shorts with high voltage tests was not thought to offset the cost of the more rigorous HV tests that would be required. , then you’ll be left with the inevitable question – what to do with the results of a cable pull test. The following changes were implemented in A-620 Rev B: Table 19-2, Continuity Test Minimum Requirements, Class 3 (Proposed by Cirris): Rev A: “2 ohms or 1 ohm plus the resistance of wire whichever is greater” Rev B: “2 ohms or 1 ohm plus the maximum specified resistance of wire whichever is greater”. If results from pull force tests are within an allowed range, it assures that the proper crimp force has been applied during the crimping process. We’ll unpack that issue in this article. UL regularly requires 100% production tests in the thousands of volts on components and products that are rated at a working voltage of 120VAC. It is highly recommended (but not mandatory) for AFI Level 2 certified practitioners in v2.0 and aspiring Level 2 candidates who have already attended a Level 2 training in v2.0 to attend a level 2 training in v3.0. Evaluation based on IPC A-620 sec. 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. SHINE is a member of the Wire Harnessing Manufacturers Association (WHMA), a leading trade organization that works closely with IPC – Association Connecting Electronics Industries to maintain this standard. Increased corporate focus & certifications Compulink has an established full-time training position for the IPC-620 workmanship standard for cable and harness assembly. Non-uniform plastic deformation occurs when the deformation is unevenly distributed along the cable, commonly referred to as “necking.” After a period of non-uniform deformation, the test article ultimately breaks. 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. Which type of influenza targets mostly pediatric clients? The IPC-A-610 “Acceptability of Electronic Assemblies” is the most widely used inspection standard for PWB manufacturing and assembly for commercial electronics. With clearance distances (air gaps or creepage) ≥2 mm [0.079 in] and not coaxial/biaxial/triaxial assemblies: Voltage Level: 1500 VDC or equivalent peak AC voltage, Max Leakage Current: 1 mA, Dwell time: 1 Second. The point at which a test article goes from elastic deformation to plastic deformation is called yield, and that point of measurement is its Yield Strength. Pull Tester. Local Area Network (LAN) cables. IPC/WHMA-A-620 Note: Suppliers and their sub-tier suppliers (where applicable) shall comply with the mechanical tests stipulated in IPC/WHMA-A-620, 19.7.2 for verifying crimp tensile strength (pull testing) of a crimped contact to connector joint. This material is advisory only and its use or adaptation is entirely voluntary. Please call or email our knowledgeable team to review your needs. Influenza A b. SAE/USCAR-21 3. The A-620 also specifies that any samples that are used for pull testing … Therefore, wire harness testing is absolutely critical. Upon satisfactory completion, students will be able to download a PDF of his/her certificate. Here, the x-axis shows the travel, or how long the cable stretches, measured by inches in this example. They are patterned after tests such as MIL-STD-201 and other requirements that have existed for over 50 years and used on assemblies with much lower working voltages.
