PCBA Heat Shrink · Solder Joint & Harness Protection
Solder joints and wire harnesses are often the most vulnerable parts of a PCBA.
Exposed solder joints
two wires touch each other and short circuit
Loose wires
a single tug pulls them off the board
Repeated bending
at the wire root — solder joints crack
Too many wires
no one knows which is which
Insulation
Encapsulates solder joints and wire harnesses, prevents shorts
Wire management
Bundles multiple wires together — neat, tidy, easy to assemble
Strain relief
A piece of tubing at the wire root absorbs bending stress before it reaches the solder joint
Identification
Printable heat shrink tubing shows wire numbers and functions clearly
Sealing
Blocks moisture, dust, and chemical gases
You specify the location, length, and color. We apply the tubing where you need it.
50 pieces minimum. Prototype · Small batch · Mass production — all accepted.
