Protecting solder joints from breaking with strain relief products

29-04-2025 | SV Microwave | Industrial

RF cable assemblies can easily be damaged if not handled correctly. Rough manoeuvring or extreme bending can lead to kinks in the cable braid and solder joint damage. To solve this issue, SV Microwave developed a line of strain relief products:

Extended ferrule RF cable connectors

When soldering a connector to a cable, the solder can wick up the cable braid during assembly, creating a rigid section behind the connector. When flexed, this area will crack and break.

The company’s Extended Ferrule RF Cable Connectors feature a longer-than-normal ferrule that protects the solder joints and fragile cable sections, offering strain relief. The extra length on the cable ferrule contains the solder wicking, protecting your cable and solder joint from breakage due to:

  • Severe flexing
  • Bending
  • Pulling on the cable

Additionally, this allows for a bend immediately after the connector.

This is most useful for a smaller diameter Ø.047” flexible cable that sees regular flexing. The company provides this product line through its distribution partners, making it available at a competitive price.

RF cable assemblies with strain relief boot

However, the extended ferrule is not the only strain relief-oriented product the company has launched; it also developed the RF Cable Assemblies with Stain Relief Boot.

The strain relief boot features a boot as an external accessory that is assembled onto the connector. This boot protects the cable from overbending during:

  • Frequent handling
  • Mating/demating
  • Manoeuvring

This is done by gradually bending and moving the cable bend away from the connector.

These cable assemblies, which feature an ergonomic finger grip and protect the cable braid from damage and kinks, are available in male SMA, 2.92mm, 2.4mm, or 1.85 series and in Ø.047 and Ø.087 standard and low-loss cable assemblies.

The company's strain relief products protect the solder joint and fragile cable sections by:

  • Containing solder wicking
  • Moving the cable bend further away from the connector
  • Adding a gradual bend

All of these options effectively protect your cable and joint from breakage, ensuring peak performance. To learn more about these products, please visit the SV Microwave website.
