✓ Surface Mount PCB Assembly (SMT)
✓ In-line & Offline AOI Inspection Process
✓ Through-Hole PCB Assembly (PTH)
✓ Prototype & NPI PCB Assembly Process
✓ Low to Medium Volume Production – High Mix
✓ Cable & Harness Design & Assembly
✓Box build & mechanical assembly & functional testing
Fast Track NPI & Prototype PCB Assembly
We support quick turn PCB assembly for time-critical projects, including rapid prototype builds and urgent production requirements.
Typical lead times include:
✓ Prototype PCB Assembly: from 72 hours (subject to BOM and complexity)
✓ Quick Turn SMT Assembly: fast-track options available
✓ Production Runs: scheduled and repeatable lead times
Our in-house assembly capability and established supply chain allow us to respond quickly without compromising on quality or process control.
SMT PCB Assembly (Surface Mount Technology)
Our SMT PCB assembly services utilise automated solder paste printing, high-speed pick-and-place machines, in-line pre-reflow AOI, controlled reflow using ERSA ovens and a post reflow AOI inspection with Mirtec.
This ensures:
✓ Accurate component placement
✓ Consistent solder joint quality
✓ Repeatable results across SMT production runs
We support high-mix, low to medium volume PCB assembly, ideal for OEMs managing multiple product lines.
Through-Hole PCB Assembly (PTH)
We provide both lead and lead-free through-hole PCB assembly to support mixed-technology products.
Our capabilities include:
✓ Automated lead preparation
✓ Wave soldering processes – Lead Free/RoHS
✓ Efficient handling of both low and higher volume builds
This allows cost-effective production without compromising on quality control.
Complex PCB Assembly (BGA, QFN, LGA)
We support advanced PCB assembly requirements, including:
✓ BGA & Micro BGA (Ball Grid Array)
✓ QFN (Quad Flat No-lead)
✓ LGA (Land Grid Array)
✓ 0201, 0.25mm pitch SMT
Using specialist placement, reflow, and inspection equipment, we ensure reliable soldering and long-term product performance for volume PCB assembly, ideal for OEMs managing multiple product lines.
PCB Assembly FAQ’s
What information do you need to quote PCB assembly?
To provide an accurate quotation, we require Gerber files, a Bill of Materials (BOM), relevant assembly drawings, test procedures and any SOW’s. A complete and structured data pack allows us to review manufacturability early and ensure we understand the specific details to support a smooth transition into production.
Do you support both prototype and production builds?
Yes, we support the full product lifecycle—from prototype and design validation through to low, medium, and volume production. Our processes are designed to ensure consistency between initial builds and ongoing repeat manufacture.
What are your typical PCB assembly lead times?
Lead times typically range from 5 to 30 working days depending on build complexity, component availability, and order volume. As a UK-based manufacturer, we focus on maintaining stable lead times and clear communication throughout the process.
How do you ensure PCB quality and consistency?
Quality is controlled through structured assembly processes, IPC-trained operators, and inspection methods including AOI, ERSAscope optical camera, 3D X-Ray and functional testing. All builds are supported by full traceability and manufacturing aligned to ISO 9001 standards, ensuring repeatable and reliable results.
Can you source components as part of the PCBA and SMT assembly?
Yes, we provide full component sourcing through a trusted and established supply chain. This includes managing lead times, obsolescence risks, and supplier control to ensure continuity of supply across both prototype and production builds.
What types of PCBs can you assemble?
We support a wide range of PCB technologies, including SMT (Surface Mount Technology) using BGA (ball grid array), fine pitch <0.25mm, leadless modules, WSCP, QFN, DFN, 0201 and 0402 components. Our capability is suited to high-reliability applications where consistency and process control are critical.
