Service
PCB Assembly
PCB assembly at Energetika-VDS runs through an in-house SMT PCB production line: solder paste printing, automated pick-and-place assembly, soldering and reflow, AOI on every board, with optional firmware loading. Functional test is sourced through partner test houses when the customer test plan requires it. Through-hole assembly is supported as a secondary option.
What this service includes
- Surface-mount assembly on the in-house SMT PCB production line
- Through-hole assembly when required
- Solder paste printing, pick-and-place, and lead-free reflow
- Automated optical inspection against IPC-A-610 acceptance criteria, in-house on every board
- Optional firmware loading
- Functional test coordinated through partner test houses when the test plan requires it
- Optional box-build support
- Component sourcing support when required
- Pilot batch through repeat PCB assembly production

- OUTPUT
Technical scope
- Board size
- 330 to 343 mm by 304 to 813 mm
- Component range
- 0201 to 35 mm bodies, BGA, 15 mil pitch QFP
- Solder profile
- Lead-free SAC305 capable
- Acceptance criteria
- IPC-A-610 Class 2 or Class 3
- Volume range
- NPI pilots through recurring production. Approx. 4.8 M placements per shift-year on the line; 80 000 simple boards or 12 000 meter-class boards per single-shift year, scalable across shifts.
Right fit when
- You need a European partner for PCB assembly with in-house SMT capability.
- You want assembly with AOI and acceptance criteria discipline on every board.
- You want one partner for assembly, firmware loading, sourced functional test coordination, and box-build.
Frequently asked questions
What is your minimum order quantity?
No fixed minimum. We run NPI pilots from a single unit through recurring production into the tens of thousands per year. Single-shift line capacity is approximately 4.8 million component placements per year; programmes above that level we plan jointly across multiple shifts during DFM and BOM review.
What lead times can we expect?
New product introduction takes about 4 to 8 weeks depending on component availability and test fixture readiness. Repeat batches typically run on a 3 to 5 week cadence once tooling and test plan are in place.
Do you manage component sourcing?
Yes. We work from your approved vendor list (AVL) or build one with you, including dual-source identification for lead-time risk. We flag obsolete or long-lead parts during DFM review and propose alternates when needed.
Which design files do you accept?
Gerber RS-274X, ODB++, and IPC-2581 for PCB data. BOM in xlsx or csv with manufacturer part numbers. CPL or pick-and-place file in csv or txt. Step files for enclosures. Firmware binaries as hex, bin, or signed image bundles.
How is solder joint quality verified?
Automated optical inspection runs on every assembled board against IPC-A-610 acceptance criteria. We support Class 2 and Class 3 inspection profiles. X-ray inspection is available through partner labs for BGA and high-density boards when required.
