What We Do Best

Repeatable, clean solder joints with proper hole fill, wetting, and lead protrusion—documented and verified.

Mixed-technology assemblies (SMT + THT)
Harnesses, connectors, terminal blocks, high-mass components
Tall/heavy parts & field-serviceable designs
Lead forming, clinching, heat-sink assembly
Cleanliness control & ionic contamination checks
Prototype & NPI
Low-to-Mid Volume
Class 2/3
RoHS / SnPb

Our THT Process

1) DFM & Build Plan

We review BOMs, tall/heavy parts, hole sizes, and thermal mass to define selective/wave/hand strategy & fixtures.

2) Controlled Soldering

Lead-free and tin-lead profiles, nitrogen assist where appropriate, and proper flux selection for cleanliness and hole fill.

3) Inspect & Test

IPC workmanship checks, AOI (where applicable), ICT/FCT options, and documented acceptance criteria.

Finishing Options

  • Conformal coating (acrylic/urethane/silicone)
  • Potting & encapsulation
  • Cleaning to spec; ionic testing upon request
  • Serialisation, labeling & packaging to SOP

Beyond the PCB

  • Wire/cable harness & panel assembly
  • Electromechanical/box build integration
  • System test, burn-in & documentation

    Through-Hole Assembly FAQs

    Do you support both RoHS and tin-lead builds?
    Yes. We maintain segregated materials, tools, and profiles for lead-free and SnPb processes.
    What volumes are a good fit?
    Prototypes through low-to-mid volume production runs, including recurring batches and spares.
    Can you develop selective solder pallets and test fixtures?
    Absolutely. We design and source pallets, wave solder fixtures, ICT/FCT fixtures, and handling aids.
    What acceptance criteria do you build to?
    IPC-A-610 and J-STD-001 (Class 2 or 3 per your requirement), with documented FAI and lot traceability when specified.
