How to Protect Your Solder Joint From Breaking - Strain Relief Products

April 15, 2025

RF cable assemblies can easily be damaged if not handled correctly. Rough maneuvering or extreme bending can lead to kinks in the cable braid and solder joint damage. To solve this issue, we’ve 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.


Extended Ferrule RF Cable Connectors

SV’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.


Solder Wicking on BendingSolder Join Protection on Bending

This is most useful for a smaller diameter Ø.047” flexible cable that sees regular flexing. SV Microwave offers this product line through our distribution partners, making it available immediately at a competitive price.

 

RF Cable Assemblies with Strain Relief Boot

 

However, the extended ferrule isn’t the only strain relief-oriented product we’ve launched; we’ve also developed our RF Cable Assemblies with Stain Relief Boot.



RF Cable Assemblies with Strain Relief Boot

 

SV’s 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
  • Maneuvering 

 

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 both Ø.047 and Ø.087 standard and low-loss cable assemblies.

 

SV’s stain 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 our site or contact our team of experts at application@svmicro.com.
