Sound familiar?
Most companies come to us after the same three problems.
We've had the same conversation hundreds of times. Here's what we hear most.
"Our CEM keeps missing deadlines — and we're the ones who suffer."
Production delays cascade. Your customers feel it before you do. When your manufacturer doesn't treat your schedule as their priority, you pay the price.
"We don't know what's happening until something goes wrong."
No visibility into the build process. No updates unless you chase. No accountability when quality falls short. You're left guessing until the delivery lands.
"Our volumes have grown but our manufacturer hasn't grown with us."
What worked at prototype stage doesn't scale. You need a partner who can handle full production runs without compromising quality or communication.
We built ABL around fixing all three.
How we work
The ABL Build Process: From Brief to Board.
Every project follows the same rigorous process — so you know exactly what to expect at every stage.
Brief & Review
We review your Gerber files, BOM, and spec requirements before we quote — flagging any DFM issues early.
Component Sourcing
We manage your BOM through approved distributors, flagging long-lead items and risks.
PCB Assembly
SMT and through-hole assembly using pick-and-place and selective soldering.
AOI Inspection
Automated Optical Inspection ensures issues are caught early and resolved.
Delivery & Support
Full documentation and traceability included with ongoing support after delivery.
What clients say
Don't take our word for it.
Here's what the companies we build for have to say.
"We chose ABL Circuits not just because they are close by, but because they share our commitment to quality and innovation. Like us, they invest heavily in their equipment and processes, which gives us confidence that every product will meet the highest standards. We always aspire to breakdown the barriers of a traditional customer-supplier relationship and encourage long-standing partnerships to flourish. This has certainly been the case with ABL over the last few years, and long may it continue."

Case studies
Real projects. Real outcomes.
We let the work speak for itself.
Who we work with
Built for the industries where quality isn't optional.
Aerospace
Assemblies built to the precision requirements of aviation — fully traceable, inspection-documented, and delivered on schedule.
We routinely supply assemblies requiring full build traceability and IPC-A-610 Class 3 workmanship standards.
Defence
Secure, reliable electronic assemblies for defence programmes — with documentation standards and supply chain integrity to match.
Our defence builds are delivered with full component traceability from approved supply chains — no grey market parts, ever.
Industrial & OEM
From small batch to high-volume production, we support OEMs who need consistent quality and fast turnaround at scale.
We regularly support OEMs running quarterly production volumes from 500 to 10,000+ units with consistent 2–4 week build cycles.
Communications
Complex, multi-layer PCB assemblies for communications equipment — precise, tested, and ready to integrate.
We handle boards up to 14 layers with fine-pitch SMT components down to 0201 — including RF-sensitive assemblies requiring controlled environments.
FAQs
Questions we hear most often.
What is Contract Electronics Manufacturing (CEM)?
CEM means outsourcing the design, assembly, and production of your electronic products to a specialist manufacturer. A good CEM partner manages everything — component sourcing, PCB manufacture, assembly, inspection, and testing — so you don't have to build the capability in-house.
Can ABL Circuits support prototype and low-volume builds?
Yes. We work with companies at every stage — from a single prototype to tens of thousands of units. Whether you're proving a concept or scaling into full production, we apply the same quality process regardless of volume.
How does ABL Circuits ensure quality across every build?
Every assembly goes through Automated Optical Inspection (AOI) at multiple stages — not just final inspection. We're ISO 9001 certified and maintain detailed quality records for every build, with full traceability from component to completed assembly.
What are your typical lead times for PCB assembly?
Prototype builds typically complete within 5–10 working days from confirmed BOM and approved files. Volume production runs are generally 3–5 weeks depending on complexity and component availability. We'll give you a realistic timeline upfront — not one we walk back later.
Why should I choose a UK CEM over an offshore manufacturer?
Shorter lead times, tighter communication, and no hidden freight or duty costs. Working with a UK manufacturer means you can visit the facility, speak to your engineer directly, and have real accountability — not an email chain to a different time zone.
What industries does ABL Circuits specialise in?
Our work spans aerospace, defence, industrial, communications, automotive, energy, healthcare, and OEM manufacturing. Many of our clients work in sectors where reliability is non-negotiable — and we've built our processes around those standards, so every customer benefits regardless of industry.
