PCBA Services. Assembled Right. Tested Before It Leaves.
Surface mount, through-hole, prototype builds, and production runs — Mascot Nexgen delivers PCB assembly with the technical rigour your design demands and the turnaround your timeline requires.
Assembly Is Where Designs Either Work or Don't
A well-fabricated board means nothing if the assembly is wrong. Misplaced components, poor solder joints, incorrect orientation — assembly errors are the most common and most avoidable cause of board failures at bring-up.
Mascot Nexgen’s PCBA process is built around precision at every stage — from BOM verification and component kitting, through SMT placement and reflow, to post-assembly inspection and functional testing. We don’t ship boards that haven’t been checked.
Whether you’re building 5 prototype units to validate a design or scaling to a 1,000-unit production batch, the assembly standard doesn’t change. What changes is the quantity on the work order.
What We Assemble
SMT Assembly
Surface Mount. Placed with Precision.
Surface mount technology is the backbone of modern electronics assembly. Fine-pitch ICs, 0402 and 0201 passives, BGAs, QFNs, SOICs — our SMT line handles the component density and placement accuracy that today’s compact, high-performance designs require.
Every SMT run goes through solder paste inspection, automated placement, reflow profiling, and post-reflow AOI (Automated Optical Inspection) — so placement errors are caught at the line, not at bring-up.
- Fine-pitch IC placement — down to 0.4mm pitch QFN and QFP packages
- 0402 and 0201 passive component placement
- BGA and LGA package support on request
- Lead-free (RoHS) and leaded solder process options
- Nitrogen reflow available for oxidation-sensitive assemblies
- Gerber RS-274X and ODB++ accepted
- X-ray inspection for BGA and hidden-joint packages on request
Ideal for: High-density digital boards, microcontroller-based designs, RF modules, power management boards, sensor-heavy assemblies
Ideal for: Power electronics, motor controllers, industrial control boards, connector-heavy designs, mixed SMT + THT assemblies
Through-Hole Assembly
Through-Hole Done with the Same Rigour.
Through-hole components aren’t legacy — they’re often the right choice for high-current connectors, power terminals, mechanical switches, and any application where structural integrity under stress matters. Mascot Nexgen supports manual and selective through-hole assembly alongside SMT builds, so mixed-technology boards don’t require a second vendor.
- Manual through-hole placement and soldering
- Selective soldering for mixed-technology boards
- High-current terminal and connector assembly
- Axial and radial component placement
- Wave solder process available for full through-hole boards
- Post-solder visual inspection and continuity check
Prototype Builds
First Builds That Give You Honest Answers.
A prototype assembly isn’t just about having boards to test — it’s about getting accurate, build-representative units that tell you the truth about your design before you commit to production quantities. Mascot Nexgen approaches prototype builds with the same process discipline as production runs — because shortcuts at the prototype stage create problems you discover too late.
We support low-quantity builds with full BOM kitting, component verification, and bring-up support. If something doesn’t pass inspection, we tell you what we found and why — not just that it failed.
- Minimum order: 1 unit
- Full BOM kitting and component verification before build
- Mixed SMT and through-hole support
- Build notes and assembly deviations documented
- Bring-up support — we flag anomalies before delivery
- Fast turnaround — prototype priority track available
Ideal for: Hardware startups, R&D teams, pre-certification builds, investor demo units, design validation builds
Ideal for: OEMs scaling to volume, EMS partners needing overflow capacity, hardware companies moving from pilot to full production
Production Support
Scale Without Losing Control.
Scaling from prototype to production is where most hardware companies hit friction — new vendors, new processes, inconsistent output. Mascot Nexgen keeps the same team, the same process, and the same component sourcing partner from your first prototype through your first production batch.
When you’ve already built prototypes with us, your production run starts with a team that already understands your board, your BOM, and the quirks your design brought forward from development.
- Batch sizes from 50 to 5,000+ units
- Component supply chain managed in-house
- Production traveller and traceability documentation
- First Article Inspection (FAI) before full run release
- Yield tracking and defect reporting per batch
- Ongoing supply chain continuity — not just a one-time build
Functional Testing
Tested. Verified. Shipped with Confidence.
Assembly inspection tells you a board is built correctly. Functional testing tells you it actually works. Mascot Nexgen includes visual and electrical inspection as standard, with functional test support available for designs where end-to-end verification matters before a board ships.
For production runs, functional testing isn’t optional — it’s the checkpoint between assembly and delivery.
- Automated Optical Inspection (AOI) — standard on all SMT builds
- X-ray inspection — BGA, QFN, and hidden-joint verification
- In-Circuit Testing (ICT) — on request for production runs
- Functional power-on testing — supply voltage, current draw, basic IO verification
- Custom test fixture support — for designs with specific test requirements
- Test reports included with production batch delivery
Ideal for: Production builds, safety-critical assemblies, designs going into customer hands, any board where a field failure is not an option
THE MASCOT NEXGEN PCBA PROCESS
How a Build Actually Happens
RFQ Submission
Upload your BOM, Gerber files, and assembly drawings. Tell us quantity, timeline, and any special requirements.
BOM Review & Component Verification
We verify every line item — part numbers, footprints, substitutes, lead time, and availability — before the build starts.
Component Kitting
Parts are sourced, received, and kitted against your BOM. Each component is verified against spec before it goes to the line.
Solder Paste & SMT Placement
Stencil-applied solder paste, SPI (Solder Paste Inspection), automated SMT placement to your centroid file.
Reflow & Through-Hole
Reflow oven with profiled temperature curve. Through-hole assembly follows for mixed-technology boards.
AOI & Visual Inspection
Automated Optical Inspection catches placement errors, solder bridges, missing components, and polarity issues.
Functional Testing
Power-on verification, IO checks, and any custom functional test procedures defined for your design.
Delivery & Documentation
Boards are packaged, labelled, and shipped with full build documentation — BOM used, components sourced, test results, and any deviations noted.
WHY PCBA WITH MASCOT NEXGEN
What Makes the Difference
BOM Ownership
We don’t just assemble what you send us. We review, verify, and manage your component supply — so shortages and substitutions are handled before they become a build delay.
Prototype and Production — Same Process
Your prototype isn’t assembled on a breadboard. It goes through the same SMT line, the same inspection, the same documentation as a production run.
AOI on Every SMT Build
Automated optical inspection is not an add-on — it’s standard. Every SMT assembly gets inspected before it leaves the line.
Mixed Technology — One Vendor
SMT and through-hole on the same board, assembled by the same team. No splitting your build between two suppliers and hoping the handoff works.
Full Traceability
Every production build ships with documentation — components used, sources, test results, deviations. You know exactly what’s in your board.
Direct Communication
You speak to the team building your boards — not a sales layer that relays messages to the floor. Questions get answered by people who have your design open in front of them.
