Quality standards and testing of high precision cable assembly
 Jun 16, 2021|View:550

high precision cable assemblies are at the heart of many conductive interconnect solutions from the module level to complete systems. high precision cable assemblies are used in a wide range of applications from low cost consumer device connectivity to the extreme precision and reliability required for aerospace and satellite communications. high precision cable assemblies are used in R&D to defense applications to transmit RF signals from the kilohertz level to over 100 gigahertz. precision cable assemblies are used in R&D to defense applications to transmit RF signals from the kilohertz level to over 100 gigahertz. It is therefore crucial to ensure that high precision cable assemblies meet the requirements of the given application. The quality of high precision cable assemblies varies widely depending on the use case and the wide range of coaxial cable designs, characteristics and specifications.

The main factor determining the quality of high precision cable assemblies is the material used for construction, design, assembly, post processing and testing.

Since most high precision cable assemblies sold are assembled using automation, quality checks must be performed at every step to ensure that the final cable delivered to the customer meets all advertised standard requirements and specifications stated in the data sheet. These low-cost coaxial assemblies for consumer applications may not undergo rigorous quality checks and may pass only one electrical test prior to shipment. Many coaxial cable manufacturers reduce costs and increase the amount of testing equipment by simplifying testing because quality testing directly increases the total cost of assembly.

However, there are many high precision cable assembly cases that require stringent quality control measures and complete documentation of verification and quality control testing. These applications include aerospace, defense, and satellite communications. RF test labs also require stringent quality control and testing, although they may not require in-depth documentation of critical applications.

For applications that require comprehensive documentation of the quality of high precision cable assemblies, such documentation begins well before construction. For example, defense standards require that the facilities and processes used for cable assembly be documented even for materials used in the construction of HIGH PRECISION CABLE ASSEMBLY. Such care is required because in the event of a failure, the root cause can be determined so that the effects of any potentially defective materials or manufacturing practices can be minimized.

In addition to testing for material quality, high-qualityhigh precision cable assembly is subject to mechanical and electrical influences at various stages of the assembly process. This includes securing pins and connector attachments, crimping/soldering the coaxial cable connector to the coaxial cable, and measuring the position of the pins, insulators, and external conductors to ensure that the cable and connector assembly is assembled within acceptable tolerances.

After mechanical quality testing, electrical quality testing is performed. high precision cable assembly data sheets are typically used to indicate the range of all relevant electrical parameters of the assembly. These typically include insertion loss, voltage standing wave ratio (VSWR), dielectric withstand voltage (DWV), impedance, and may include certain additional parameters such as passive intermodulation (PIM) response, phase delay, propagation speed, etc. Depending on the needs of a particular application, additional electrical parameters may also need to be tested, such as PIM for telecommunications applications and phase stability for high-performance RF testing.
