Spirit Circuits Limited

What Spirit Circuits Limited does

Spirit Circuits Limited is a UK-based printed circuit board (PCB) manufacturer operating as part of SCL PCB Solutions Group, headquartered in Waterlooville, Hampshire. Founded in 2007, the company manufactures and supplies standard multilayer PCBs, Metal Clad Printed Circuits (MPCBs / Insulated Metal Substrate PCBs), flexible circuits, and complementary Thermal Interface Materials (TIMs) from its UK facility, while running a China sourcing office in Dongguan for cost-optimized standard production. It serves LED lighting, power conversion, rail/transportation, automotive, and — through its Lyncolec subsidiary — aerospace, military, defense, medical, and oil & gas customers. Its core differentiators are the "Ask Dave" guaranteed 48-72 hour quick-turn service with £1,000 compensation clauses, a free prototype service ("Go Naked"), a patented embedded RFID tracking technology, and a predictive analytics system built with NLP Logix that flags customer dissatisfaction risk before it escalates.

The company monetizes PCB manufacturing through project-based orders (one-time contracts) across its quick-turn, standard, and high-reliability lines, supplemented by a recurring £100/month "Flexitool" tooling subscription and revenue from Lyncolec's high-reliability aerospace and defense work. GTM is direct sales-led with a UK team (Sales Director Lee Lloyd, technical and area sales managers, sales engineers) supported by regional agents in Germany (Rupert Harzenetter) and the US (Tom Sleasman), plus a China sourcing office for supply chain. Marketing is multi-channel, including major trade shows (Electronica, LuxLive, Productronica, Farnborough), Steve Driver's blog, the YouTube "Circuit Channel," the boardSTIFF newsletter, and ICT seminar hosting. Strategic growth has been driven by three acquisitions (Lyncolec in December 2013, Teknoflex equipment in July 2014, CPL Circuits in 2015) and product line extensions into TIM and RFID. The company holds ISO 9001, ISO 14001:2004, UL Component Recognition (US and Canada), and — via Lyncolec — Nadcap and SC21 Silver accreditations.

Scale indicators7 records

Recent moves6 records

Expansion highlights7 records

Direct peers

• Graphic PLC: UK-listed PCB manufacturer of comparable size, offering a similar range of rigid, flex and high-reliability PCBs to UK and European customers. Most directly comparable UK peer given overlapping geography, customer base and product breadth.
• Eurocircuits: European PCB prototype and small-batch manufacturer (Belgium/Hungary) with a strong service-led, online quoting model. Comparable to Spirit's Ask Dave quick-turn positioning and growing pool/PCB Snap customer base.
• Beta LAYOUT: Germany/Europe-based PCB and PCB-pool service for prototypes and small series. Directly comparable on quick-turn PCB services for European SMEs, the same target customer Spirit pursues in Germany.
• Rush PCB Inc: US quick-turn PCB manufacturer focused on fast-turn prototyping and small batch production. Closest international peer to Spirit's Ask Dave service in terms of speed-led value proposition and customer profile.
• Sierra Circuits: US PCB fabricator specialising in quick-turn prototypes, high-density interconnect and high-reliability boards. Comparable across Spirit's quick-turn commercial work and Lyncolec's high-reliability aerospace/defense business.

Regional players

• Multi-CB / LeitOn Group: German PCB manufacturer offering prototype to series production including rigid, flex and rigid-flex. Comparable in product range; primarily serves the DACH region where Spirit is building presence via Rupert Harzenetter.

Broad incumbents

• AT&S: Austrian-headquartered global PCB and IC substrate manufacturer serving automotive, industrial, medical and high-end computing. A broad incumbent against whose scale Spirit must position its quick-turn and thermal-management niche.
• TTM Technologies: Large US-headquartered PCB manufacturer with strong aerospace/defense, automotive and data-center exposure. Directly comparable to Lyncolec's Nadcap/SC21-certified aerospace/defense business, though at vastly greater scale.

Emerging players

• PCBWay: China-based low-cost PCB prototype and small-batch manufacturer with online quoting and quick-turn capabilities. Sets the price/turnaround benchmark Spirit's Ask Dave and PCB Snap services must defend against.
• JLCPCB: Shenzhen-based high-volume, low-cost PCB and PCB-assembly service. The dominant emerging low-cost competitor whose continued improvements in quick-turn and small-batch service pose a structural threat to UK-based premium positioning.
