Precision PCB SMT Assembly – Fine-Pitch & BGA Expert
Overview
As electronic components continue to shrink—fine-pitch BGAs, 01005
passives, and complex QFN packages—precision placement becomes
critical to product reliability. Studio Electronics delivers Precision PCB SMT Assembly with expertise in fine-pitch and BGA components. As a
precision-focused provider of PCB assembly in China, our 12 automated SMT lines provide ±25μm placement accuracy,
essential for low volume PCB assembly that incorporates advanced components. Our complete turnkey
process from order receipt through component procurement,
fabrication, assembly, testing, and shipping is engineered for
precision, with strict quality control ensuring every board meets
your exacting specifications.

Precision Production Process – From Order to Delivery
Stage 1: Order Review & DFM Analysis
Our engineering team reviews your design files with a focus on
precision requirements—fine-pitch components, BGA layouts, and
critical tolerances. DFM feedback optimizes your design for
manufacturability.
Stage 2: Component Procurement
We source components with precision requirements in mind. For low volume PCB assembly, we handle small-quantity procurement efficiently. Incoming
components undergo strict verification.
Stage 3: PCB Fabrication
In-house bare board creation with controlled impedance and tight
tolerances. Multiple material and finish options.
Stage 4: Precision SMT Assembly
12 automated SMT lines with ±25μm placement accuracy. Dedicated
programming for fine-pitch components. Automatic wave soldering for
THT. Programmable soldering robots for precision selective
soldering.
Stage 5: Precision Quality Control (100% Inspection)
3D SPI – Micron-level paste measurement
3D AOI – High-precision component alignment verification
3D X-Ray – BGA/QFN void analysis; sub-10μm defect detection
ICT – Component-level electrical validation
Flying Probe – Fixture-less testing ideal for low volume PCB assembly
FCT – Functional testing simulating real-world conditions
Stage 6: Final Assembly & Shipping
Careful handling, anti-static packaging, customs clearance, and
global shipping.
