This Standard shall not be rewritten or reissued in any other form not approved by NASA. Indent crimping •May be hard on the wires/strands of the conductor •Is used primarily on Cu conductors: Punch-Matrix crimping •Has great oxide breaking properties which is necessary on Al conductors •Maintains, due to the matrix, high inner pressure during the crimping operation •Is used on Al: What is BS7727:1994? The three key elements in the crimping process are the terminal, the wire, and the tooling. Years ago I was neck-deep in cable design and assembly, and during that time I don't recall ever seeing a hand crimping tool datasheet stating that the tool would produce IPC-compliant crimps.

The IPC/WHMA-A-620 standard prescribes practices and requirements for the manufacture of cable, wire and harness assemblies. The hexagon crimp or compression is designed for a cable conductor temperature up to 90°C, according to IEC. Contact: IPC 2215 Sanders Road Northbrook, Illinois 60062-6135 Tel … The IPC/WHMA-A-620 was a collaborative effort between IPC and the Wire Harness Manufacturer’s Association. The standard describes materials, methods, tests and acceptability criteria for producing crimped, mechanically secured and soldered interconnections, and the related assembly activities (corresponding lacing/restraining criteria) associated with cable and harness assemblies… SAE AS7928, formerly MIL AS7928 and USCAR-21 are for military and automotive crimp connections, respectively. DIN standard crimping requires adherence of conductor, selected crimp cable lugs and compression die sets to provide optimum results when terminating cable lugs to DIN standards at LV MV HV. Molex SPOX tools specifically call out the compliance of IPC … IPC/WHMA-A-620 Requirements and Acceptance for Cable and Wire Harness Assemblies Developed by the IPC Task Group (7-31f) of the Product Assurance Subcommittee (7-30) and the WHMA Industry Technical Guidelines Committee (ITGC) Users of this standard are encouraged to participate in the development of future revisions. The most specific standard for wire harness makers is the IPC/WHMA-A-620 standard, covering everything from crimping and soldering to lacing and tie wrapping.

As you well know, manufacturing products based on strict industry standards creates a … Terminal For most applications, it is not economically practical for connector manufacturers to design a terminal to accept one wire size, one wire stranding, and one insulation diameter (UL type) as well as Mil Specification.
