Service 03 · Hand

Hand soldering. Where the machine can't go.

Fine-pitch QFN and TSSOP. RF connectors. Flex circuits. Coax assemblies. Rework where AOI flags a problem and you need a human eye on it. Microscope, hot air, IPC-trained hands.

// What this is

Skilled hands, stereo microscope, IPC training.

Hand soldering is the right answer when the part is too fine, too heat-sensitive, or too few in number to bother stencilling. Through-hole headers on a populated board. RF connectors that need controlled-impedance solder. A single QFN that came up short on a build run.

We don't think of hand soldering as a fallback. Some assemblies are simply better hand-soldered than reflowed. We'll tell you when that's true for your project.

// Capabilities

Specs we work to.

Min pitch	0.4 mm leaded packages, 0.5 mm QFN
Tools	Temperature-controlled iron, hot-air rework, stereo microscope (10−40×)
Solder alloys	SAC305, SnPb, no-clean and water-soluble flux
Specialty	RF coax, fine-pitch QFN/TSSOP, through-hole, flex circuits
Standards	IPC J-STD-001 / IPC-A-610 trained operators
Inspection	Microscope inspection on every joint, photo log
Throughput	1–200 boards per run; not a fit for high-volume

// Process

From bench to bench.

Send photos + part list

Even a phone photo of the board and the part bag is enough.

We quote per joint or per board

Per-joint pricing for small jobs (e.g., "12 pads on a QFN"); per-board for larger populations.

You ship parts + boards

Reels, cut tape, or loose. We'll handle the inventory while we work on it.

Solder under microscope

Each joint inspected as it's made, plus a final pass on the finished board.

Photo log + return-ship

Macro photos of the work area before and after, plus any flux-clean steps.

// Pricing

Quote-only.

Every project is priced individually. Send the details and we’ll come back same business day with a fixed-price quote, a lead time, and any DFM red flags.

// FAQ

Common questions.

I just need one connector soldered — is that worth your time?

Yes. We do single-joint jobs all the time. Bench-rate quote, in and out same week.

Can you handle controlled-impedance RF joints?

Yes — SMA, MMCX, U.FL, end-launch. We control the iron tip temperature and dwell time to avoid degrading the connector.

What about flex circuits / FPCs?

Flex is a frequent ask. We use low-temperature alloys and flex-friendly fixturing.

One board, one connector, one tricky joint?

We're set up for small jobs. Send a photo and we'll quote it.
