- Lead-free (RoHS) & SnPb process support
- First Article & Lot Traceability
- ESD-safe work areas & tooling
Process Capabilities
- Selective solder & wave solder
- Skilled hand soldering & rework
- Pin-in-paste for mixed tech designs
- Conformal coating, potting & staking
Inspection & Test
- 100% visual per IPC workmanship
- 3D AOI for mixed-tech boards
- ICT/FCT fixture development
- Burn-in / environmental options
What We Do Best
Repeatable, clean solder joints with proper hole fill, wetting, and lead protrusion—documented and verified.
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.
