What is PCB assembly
Bare board to tested assembly, in one scope.
PCB assembly (PCBA) is the process of soldering electronic components onto a fabricated printed circuit board. It covers solder paste printing, component placement, reflow or wave soldering, inspection and test. A PCB assembly manufacturer may also source components and build complete box assemblies.
Most assembly problems start upstream, in an ambiguous BOM, a finish that does not suit fine-pitch parts or a missing via-in-pad callout. Because AstroPCB fabricates the bare board and assembles it, we review the board, the BOM and the assembly documents together before anything is built.
- One supplier and one schedule for fabrication, sourcing and assembly
- BOM checked for availability and lifecycle before the quote is final
- Inspection plan matched to the components on your board
Why AstroPCB
Why choose AstroPCB as your PCB assembly manufacturer.
A PCB assembly manufacturer that also builds the bare board can fix problems at the source. We align surface finish, via treatment, panel design and stencil strategy with the components you are placing.
- Fabrication + assembly under one roof: HDI, rigid-flex, RF and heavy copper boards
- DFM/DFA review and BOM check included with every PCBA quote
- Engineering since 2008: 1,000+ engineers and 30+ partner factories in Shenzhen, Xi’an, Chengdu and Hangzhou
- Written DFM review on every order, prototype or production, before fabrication starts
- 99.6% on-time delivery across the partner factory network
- From 1 piece to volume with the same stack-up and process controls
- IPC Class 2 by default, Class 3 on request, with inspection records and batch traceability
- Fabrication plus assembly: component sourcing, SMT and tracked worldwide shipping
PCB assembly services
PCB assembly services for every stage.
Turnkey PCB assembly
We source every component, fabricate the board, assemble and test. You send files and receive finished boards.
Turnkey assemblyLow volume PCB assembly
Prototype, pilot and small-batch builds with production processes and no tooling surprises at scale-up.
Low volume assemblySMT assembly
Automated SMT from 01005 passives to 0.3 mm pitch BGAs, with SPI, AOI and X-ray inspection.
SMT assemblyQuick turn PCB assembly
Fabrication and assembly on one compressed schedule, with sourcing started the day your BOM arrives.
Quick turn PCBConsigned & partial turnkey
Supply some or all components yourself. We kit, inspect and assemble them with the parts we source.
Discuss sourcingThrough-hole & mixed technology
Through-hole and selective soldering for connectors, power and high-mechanical-load parts alongside SMT.

How it works
The PCB assembly process.
DFM/DFA & BOM review
Board, BOM and centroid checked together; shortages and alternates flagged.
Fabricate & source
Bare boards built while components are procured and kitted.
Assemble & inspect
Paste print, SPI, placement, reflow, AOI and X-ray.
Test & ship
Functional test on request, ESD packing, tracked shipping.
Quality & inspection
How every assembly is verified.
- Solder paste inspection (SPI) of volume, height and alignment
- Automated optical inspection (AOI) after reflow
- X-ray for BGA, QFN, LGA and other hidden joints
- First-article inspection before the full lot
- Functional test and programming to your procedure
- Traceability: lot and inspection records on request
US & worldwide delivery
Looking for PCB assembly near me?
Many engineers search “PCB assembly near me” because they want fast answers and predictable delivery more than a nearby building. AstroPCB assembles in our partner factory network in China. We overlap with US business hours for engineering questions and ship assembled boards by tracked express, typically in 3–5 business days to US addresses after assembly.
For US teams, see PCB manufacturer for USA customers.

FAQ
PCB assembly questions, answered.
What PCB assembly services do you offer?
Turnkey, partial-turnkey and consigned PCB assembly; SMT, through-hole and mixed-technology assembly; low volume and quick turn builds; inspection, functional test and programming.
What is the smallest component you can place?
01005 passives (0.4 × 0.2 mm) and fine-pitch BGA, CSP and QFN packages down to 0.3 mm pitch, with placement accuracy of ±25–50 µm.
Do you inspect BGAs with X-ray?
Yes. X-ray inspection is used for BGA, QFN, LGA and other bottom-terminated packages that AOI cannot see.
Is there a minimum order quantity for PCBA?
No. Assembly starts from a single board; see low volume PCB assembly.
Can I supply my own components?
Yes. Consigned and partial-turnkey assembly are supported; we inspect and kit your parts with the components we source.
Where is assembly done, and how fast do boards reach the US?
Assembly is done in our partner factory network in China. Tracked express to US addresses typically takes 3–5 business days after assembly.
What files are needed for a PCB assembly quote?
Fabrication data, a BOM with manufacturer part numbers, a centroid file and an assembly drawing. Add test requirements if needed.
