Job Description
Production Soldering Technician (Micro-Soldering)
Location: St Helens (Full Time, Onsite)
Salary: £40,000 – £45,000 per annum
KO2’s client, based in St Helens, designs and manufactures complex IP and WAN-based connectors for communication devices. Due to rapid growth and increased production demand, they are seeking experienced Micro-Soldering Technicians to join their onsite team permanently
The Role
You will be responsible for precision soldering of small-scale, high-density multi-pin connectors (including Fisher connectors) used within advanced communication systems.
The work involves:
* Micro-soldering very small hollow pins arranged concentrically
* Working under a microscope due to extremely tight pin spacing
* Preventing solder bridging and pin contamination
* Terminating fine multi-strand cable assemblies
* Supporting electrical test (pass/fail) and fault identification
* Ensuring assemblies meet high-reliability standards before potting and overmoulding
Essential Skills & Experience
* Proven experience in micro-soldering / fine-pitch soldering
* Experience soldering small multi-pin connectors or PCB components
* Confident working under magnification (microscope essential)
* Strong understanding of solder joint quality and defect prevention
* Ability to avoid bridging on closely spaced pins
* Background in electronics manufacturing, cable assembly, or connector assembly
* Comfortable working in a production environment with growing volumes
Desirable
* Experience within military, aerospace, or high-reliability sectors
* Knowledge of IPC standards (e.g. IPC-A-610)
* Exposure to cable overmoulding processes
This is a key hire within a growing manufacturing cell where quality and precision are critical.
