PCB Assembly Services
SMT assembly, mixed SMT and through-hole assembly, manual soldering and final workmanship review can be coordinated to match the board and build stage.
IN-HOUSE SMT ASSEMBLY
In-House SMT Assembly Services
Excel Circuit provides in-house SMT assembly services for prototype, pilot and low-volume PCBA projects that require controlled material handling, automated placement, reflow and inspection.

Our In-House SMT Assembly Capability
Excel Circuit operates its own SMT assembly capability to support engineering prototypes, low-volume builds and production PCBA projects. Our team coordinates component preparation, assembly, inspection and testing with direct engineering feedback when assembly issues arise.
Prototype to Production
We support first engineering builds, design revisions, low-volume requirements and repeat production without making unsupported volume or lead-time guarantees.
Direct Engineering Feedback
Assembly findings can be reviewed with our PCB and hardware engineers to address footprints, polarity, solderability and manufacturability.
Production-floor views
Inside Our In-House SMT Workflow
Existing production-floor images from the Excel Circuit website show the SMT line, component handling area and PCBA visual inspection workstation.
Controlled workflow
Our SMT Assembly Process
Each project, including a Bluetooth audio PCBA project, is reviewed against the available production data and its specific inspection and testing requirements.
BOM & production file review
Component sourcing & incoming check
Solder paste printing
SPI when specified
Automated pick & place
AOI
X-ray when required
Manual / THT assembly
Testing & final inspection
Process and inspection
SMT Equipment & Process Capabilities
Solder Paste Printing
Solder paste is applied through the project stencil before component placement.
SPI
Solder paste inspection checks paste deposition before placement when SPI is specified for the build.
Pick & Place
Automated component placement follows approved centroid data, BOM information and component orientation requirements.
Reflow
Placed assemblies pass through a controlled reflow process appropriate to the assembly requirements.
AOI
Automated optical inspection supports checks of placement, polarity, orientation and visible solder-joint conditions after assembly.
X-ray Inspection
X-ray inspection can support evaluation of hidden solder joints such as BGA assembly and QFN connections when required.
Manual & THT Assembly
Through-hole insertion, manual assembly and hand soldering can be integrated where the board requires mixed technology.
Testing
Testing is performed according to the agreed project scope and available test requirements, followed by final inspection.
Quality control
SMT Assembly Quality Control
Quality controls are selected around the board technology, component package, design risk and agreed project scope.
- Production data, BOM and assembly drawing review
- Incoming component and material checks
- Polarity, orientation and workmanship review
- SPI, AOI and X-ray applied according to project needs
- Testing and final inspection to the agreed scope
Responsive problem solving
Engineering Support During Assembly
When assembly issues are identified during prototype or production builds, our engineering team can review PCB layout, component selection, footprints, polarity, solderability and manufacturability requirements to support corrective action.
Design & Footprint Review
PCB design feedback and footprint review can help identify placement, polarity and solderability risks.
BOM & DFM / DFA Review
Component data and assembly requirements can be checked before build release to reduce avoidable production questions.
Prototype Debug Support
Prototype findings can be communicated back to the engineering team for practical issue review and revision planning.
Integrated project support
Component Sourcing + In-House Assembly
Component sourcing can be integrated with our in-house SMT assembly workflow, helping coordinate BOM requirements, component preparation, assembly scheduling and production delivery.
Fabrication coordination
Need PCB Fabrication as Well?
Excel Circuit can coordinate PCB fabrication together with component sourcing and in-house SMT assembly for complete PCBA project support.
Closer project control
Why In-House SMT Assembly Matters
Direct Process Control
Closer control of assembly scheduling, production coordination and inspection.
Faster Engineering Feedback
Assembly issues can be communicated directly with the engineering team.
Integrated Inspection
AOI, X-ray and other inspection requirements can be integrated into the assembly workflow.
Prototype Flexibility
Better coordination for engineering builds, revisions and small-volume production.
Design-to-Production Support
PCB design, sourcing, assembly and testing can be coordinated through one project workflow.

What We Need for an SMT Assembly Quote
Send the available project data so our team can review assembly, sourcing, inspection and testing requirements.
- Gerber files
- BOM
- Pick-and-place / centroid file
- Assembly drawing
- PCB fabrication data
- Special assembly instructions
- Testing requirements
- Quantity and target schedule
If some production files are not ready, our engineering team can review the available project data first.
