Solutions · PCB Assembly

Turnkey PCB assembly. 01005 to 0.3 mm BGA pitch.

SMT, through-hole, and mixed-tech assembly from prototype through production. SPI, AOI, and X-ray inline. Flying probe and bed-of-nails test. Conformal coat, underfill, programming, and serialization to your spec. Built to IPC-A-610 Class 2 and Class 3, J-STD-001 soldering.

PCB assembly, or PCBA, is the placement and soldering of components onto a fabricated board. RLX Solutions provides turnkey, kitted, and consigned PCB assembly in Canada, from prototype to production, with SMT, through-hole, and mixed-technology builds inspected to IPC-A-610 Class 2 and Class 3.

01 — Overview

Turnkey, kitted, or consigned.

Send Gerbers, BOM, and pick-and-place files, and we handle the rest — component procurement, stencil, kitting, placement, reflow, inspection, test, and shipment. This is the most common workflow and removes your procurement team from the critical path. We source through authorized distribution with our verified excess-inventory network as backup for obsolete and allocated parts.

If you'd rather own procurement, we run kitted and consigned builds too. You supply parts (optionally with shortage coverage from our inventory), and we build, test, and ship. Either way, the build quality, inspection depth, and traceability are identical — IPC-A-610 Class 2 or Class 3 to your spec, with full lot and date-code capture per ISO 9001:2015.

For the complete assembly spec envelope (component sizes, PCB envelope, inspection, test, programming, conformal coat, ESD/MSD controls), see the Capability Reference on the home page.

02 — Service tiers

Three ways we can build your PCBs.

Choose based on how much of the supply chain you want to own. All three get the same build and test quality.

TIER / 01

Turnkey

We source, build, test, ship

Send your files. We procure all components, fabricate or source bare PCBs, build, test, and ship direct to you or your customer. Most common workflow.

TIER / 02

Kitted (Partial Turnkey)

You supply critical / long-lead parts

You provide the controlled-source or custom components, we source the rest and build. Common for parts with strict supplier requirements.

TIER / 03

Consigned

You supply all parts

You ship us a complete kit; we handle build, inspection, test, and ship. No procurement on our end. Useful if you already run a mature supply chain.

TIER / 04

Class 3 / High-Rel

IPC-A-610 Class 3 build

Tighter solder-joint, component-placement, and documentation requirements for medical, aerospace, and life-safety programs.

03 — Inspection & test

Every PCB inspected and tested.

SPI
Solder Paste Inspection — 100% pre-reflow coverage · paste volume, area, and offset verified
AOI
Automated Optical Inspection — post-reflow, both sides · placement, orientation, solder joint verification
AXI (X-ray)
BGA, LGA, QFN thermal pads · void analysis · hidden joint verification
Manual visual
Per IPC-A-610 Class 2 or Class 3 criteria · trained operators under magnification
Flying probe ICT
Prototype and low-volume · no fixture · full net coverage
Bed-of-nails ICT
Production volume · customer-supplied or RLX-developed fixture
Functional test (FCT)
To customer specification · pass / fail logging with serial number traceability
First article (FAI)
Every new build · customer-signed approval before production lot release
04 — Special processes

Beyond the standard build.

Conformal coating
Acrylic · silicone · polyurethane · parylene — selective or full-PCB, masked per drawing
Underfill
Capillary flow and no-flow · BGA and CSP reinforcement for drop and thermal cycling
Potting / encapsulation
Custom-mold potting · environmental protection for harsh-environment assemblies
Programming
In-system programming (ISP / ICSP) · JTAG / SWD · bootloader and firmware flashing
Serialization
Serial number marking · MAC address programming · customer-defined schema · laser mark or label
Press-fit insertion
Tool-assisted connector insertion · DIN connector standards
BGA rework
Removal, reballing, replacement · X-ray verified
Selective soldering
Mixed-tech PCBs where wave solder isn't appropriate

Frequently asked questions

Do you offer turnkey, kitted, and consigned assembly?
Yes. Turnkey means RLX procures all parts and builds. Kitted means you supply some parts and RLX sources the rest. Consigned means you ship a full kit and RLX assembles.
What is the smallest component and finest pitch you place?
01005 passives and BGAs down to 0.3 mm pitch, including dense BGA and fine-pitch QFN, on SMT, through-hole, and mixed-technology boards.
What IPC class do you build to?
IPC-A-610 Class 2 and Class 3. Class 3 is used for medical, aerospace, and life-safety assemblies.
What files do you need for a PCB assembly quote?
A bill of materials in Excel or CSV, Gerber data, pick-and-place or centroid data, and an assembly drawing. Send what you have and our team will identify any gaps.
Can you build prototypes and production volumes?
Yes. Prototype, pilot, and production runs use the same inspection and test steps, so the record set does not change as volume grows.
Do you offer conformal coating, potting, and programming?
Yes. Conformal coating in acrylic, silicone, polyurethane, or parylene, underfill and potting, device programming, and serialization are all available.
