Our PCB Assembly Process
Every board follows the same rigorous manufacturing process, whatever the volume.
01
Design review
We check your PCB design files (Gerber files, DXF or BRD) for manufacturability before anything goes to production.
02
Component sourcing
We source through our trusted supplier network, or work from your bill of materials (BOM), with full traceability and no supply chain delays.
03
PCB fabrication
PCB fabrication is managed through our network of trusted manufacturing partners, primarily in the UK. Having been PCB manufacturers ourselves, we know what quality looks like and work only with suppliers who meet our high standards. Where larger volumes or specialist requirements call for it, we also have established overseas manufacturing partners.
04
Assembly
Automated pick-and-place machines handle component placement for SMT builds, supporting components down to FBGA and 01005, our smallest component size. Hand assembly is used for through-hole (THT) connections. Selective soldering and hand soldering are used to complete THT connections.
05
Inspection and testing
Every board undergoes 3D automated optical inspection (AOI). A range of additional testing methods is available and can be carried out as required.
06
Box build and delivery
Assemblies can be built up into full box build products, then dispatched to your timeline. Fast turnaround times as standard, with lead times agreed upfront.
PCB Assembly Capabilities
SMT
Surface Mount (SMT) Assembly
High density boards with components placed down to fine-pitch, including SMD (surface-mount device) packages. Using surface mount soldering and automated placement equipment, this method suits flex PCB, rigid PCB and high frequency SMT assembly designs.
THT
Through-Hole (THT) Assembly
Through-hole assembly, sometimes called THT assembly, gives stronger mechanical connections for high vibration or high power applications, using hand soldering methods. Meets Class 3 durability requirements where needed.
MIXED
Mixed-Technology Assembly
SMT and THT combined on a single board (mixed-technology assembly), for builds that need both high density and mechanical strength in one product.
Inspection, testing and finishing
3D automated optical inspection (AOI) on every board
Functional testing before dispatch
A range of testing options is available, from simple power-up checks through to full electrical test procedures, with recorded pass/fail data.
We offer a wide range of conformal coating options, all applied in-house using our dedicated spray booth to suit the requirements of each application.
IPC Class 3 capability for critical applications

Quality PCB assembly, every time
40+ years building PCBs you can rely on, from bare PCB to finished, tested assembly, across aerospace, defence, medical, automotive and industrial sectors.
Design review
We check your PCB design files (Gerber files, DXF or BRD) for manufacturability before anything goes to production.
Do you offer conformal coating?
Yes. Conformal coating is available to protect boards from moisture, dust, chemicals and temperature extremes.
Do you offer SMT and THT assembly?
Yes. We have dedicated automated assembly lines for both SMT and THT, ensuring the highest standards of quality in line with IPC and J-STD requirements. We also support mixed-technology builds combining both on a single board where the design calls for it.
Can you assemble prototypes as well as full production runs?
Yes. Prototype assembly, small batch and volume PCB assembly are all handled in-house, so you can test a design before committing to a full run.
Do you supply bare PCBs without assembly?
Yes. If you only need boards fabricated rather than assembled, we can supply a bare PCB on its own.
Is your PCB assembly service suitable for businesses of any size?
Yes. We provide PCB assembly services for businesses from single-product startups to established OEMs running high volume production.
What are the benefits of having ABL Circuits manage my entire PCB project?
One point of contact from design through to delivery. Fewer handoffs, faster resolution if something needs adjusting, and full accountability for the finished electronic assembly.
