Metal Core PCB Manufacturers in Spain: Companies, Capabilities and Sourcing Options

Metal Core PCB manufacturers in Spain include CIRLAN, Fast PCB, Maxwell Atlantic and CIPSA Circuits. The useful differences are practical: which IMS structures they describe, what quality controls they disclose, whether they publish a lead time, and whether they supply only bare boards or can cover a wider manufacturing scope.

If you are sourcing an aluminium or copper-base PCB, start with the structure and delivery requirement. A single-sided lighting board, a double-sided PTH IMS design and a fully assembled thermal board do not belong in the same RFQ. The comparison below shows what each supplier publicly offers and which details still need a written quotation.

Who Are the Main Metal Core PCB Manufacturers in Spain?

CIRLAN, Fast PCB, Maxwell Atlantic and CIPSA Circuits all identify finished PCB manufacturing operations in Spain and publish an IMS or metal-core offer. Their process scope and delivery visibility are not the same.

Match the shortlist to the actual build before requesting prices. Fast PCB publishes defined timing for single-sided aluminium IMS; CIRLAN provides aluminium and copper single-sided process limits; CIPSA documents double-sided and PTH aluminium structures; and Maxwell Atlantic offers broad in-house PCB inspection and traceability. Send the same material, quantity, test, dispatch-date and delivery-price requirements to the relevant suppliers so their quotations cover the same work.

CIRLAN

CIRLAN publishes one of the clearest Spanish process windows for single-sided aluminium and copper IMS. Its aluminium range lists 1.0, 1.5, 2.0 and 3.0 mm board thicknesses. Standard copper is 35 or 70 µm; 105 µm is listed as special production. The same table gives track and spacing, drill, routing, scoring, panel-size and finish limits.

That detail helps a buyer see whether a conventional IMS design falls inside the standard column before requesting a quote. It does not publish a standard turnaround or price. Ask CIRLAN to identify the dielectric grade, thermal data, metal alloy, inspection package and dispatch date for the released files.

CIRLAN separates local services from outsourced technologies. Its local scope includes engineering, optimisation, panelisation, aluminium IMS and copper IMS. The company also describes cooperation with PCB factories in Shenzhen for other technologies. If Spain production is a purchasing condition, the quotation should name the physical plant for the exact part.

Fast PCB

Fast PCB is the easiest supplier in this group to assess when the project is a conventional single-sided aluminium board and delivery speed matters. Its IMS page states 5 working days for short series, 10 working days for large series and 100 m²/day of production capacity.

The published process range covers aluminium bases from 0.8 to 3.2 mm, copper from 35 to 105 µm, a maximum delivery format of 544 × 390 mm, chemical tin, CNC routing and V-scoring. That is enough to reject obvious mismatches before engineering spends time on an RFQ.

Fast PCB also describes a metallographic laboratory that performs ageing tests, thermal shock, digital microsection measurement and solderability checks. A production certificate can be supplied with the order on request. Put the required report, sampling level and acceptance criteria into the purchase specification; do not assume every report is included in the unit price.

Its public IMS offer is specifically single-sided aluminium. Copper-base, plated-through-hole, double-sided IMS and alternative finishes need an explicit technical answer and separate schedule.

Maxwell Atlantic

Maxwell Atlantic is relevant when a buyer wants broad in-house PCB process control as well as an aluminium or copper IMS option. The Santiago de Compostela company states that its PCB manufacturing is carried out without third-party subcontracting and can cover prototypes plus small, medium and large series.

Its listed equipment and processes include CNC drilling and milling, lamination, single-, double- and multilayer etching, electroplating, desmear, AOI, solder-mask processing, laser marking and flying-probe electrical test. The quality system follows UNE-EN-ISO 9001, and the company describes full traceability for raw materials and test results.

This is useful quality evidence, but the public pages do not provide an IMS-specific lead-time table or detailed metal-core process window. The quotation should therefore state the exact IMS structure, dielectric, thermal and isolation values, PTH method, inspection reports, quantity break and committed dispatch date. Ask for the IMS limits, not a general PCB capability list.

CIPSA Circuits

CIPSA Circuits publishes the widest aluminium IMS structure range among the four companies compared here. Its capability material covers single-sided boards, isolated holes, openings in the aluminium, double-sided PTH with an aluminium base and double-sided constructions with an aluminium core. Several structures list 35 or 70 µm copper and 0.15 mm line and spacing.

CIPSA states on its quality page that it performs rigorous controls throughout manufacturing and retains traceability for raw materials and test results. Its general prototype service runs from 24 hours to 5 days and uses the same production lines and finishes as series manufacture. Because that timing page covers PCB prototypes broadly, ask CIPSA to confirm whether the actual IMS material and construction qualify for the requested expedite window.

CIPSA is a strong technical candidate for aluminium IMS that goes beyond a basic single-sided board. Copper-core IMS, the current revision of the capability data, inspection deliverables, setup charges and freight to the final destination still need to appear in the quotation.

How Do These Metal Core PCB Manufacturers Compare?

Do not compare four unit prices until every quote covers the same material, tests, quantity, delivery point and service scope. A cheaper line item can become the expensive choice once tooling, certificates, freight or a second supplier for assembly is added.

Ask for two dates: the factory dispatch date and the expected delivery date at your site. A five-day fabrication promise is not a five-day delivered order if material approval, engineering questions or freight sit outside the quoted clock.

What Should You Check Before Choosing a Metal Core PCB Manufacturer?

Approve the complete thermal and commercial build, not just an “aluminium PCB” label. These checks prevent the most common gaps between an attractive quotation and the board that actually arrives.

• Lock the thermal stack: name the IMS material, metal alloy, dielectric thickness, dielectric performance, finished copper and total board thickness. Ask whether the thermal value is typical or guaranteed.
• Define electrical isolation: specify working voltage, test voltage, dwell time and acceptance limit. For PTH IMS, require the supplier to show how barrels and pads are isolated from the metal.
• Control the mechanical interface: include outline, flatness, hole and slot tolerances, burr limits, countersinks, V-score and the heat-sink contact surface.
• Check repeatability: ask which material and factory will be used for prototypes and series. Any material or site substitution should need written approval.
• Match the inspection to the risk: define electrical test, isolation test, dimensional report, material certificate, first-article check and lot traceability. State which documents must ship with the boards.
• Close the delivery assumptions: agree when the clock starts, what pauses it, which parts of the schedule are expedited and whether the promised date is dispatch or arrival.

For a pilot order, keep the supplier’s deviations list with the approved files. When the board moves into repeat production, compare the new material lot, factory, process and test plan against that record before release.

EBest Circuit – An Overseas Metal Core PCB Manufacturing Option for Spain

If the project does not require Spain-local fabrication, EBest Circuit can combine metal-core PCB fabrication, component sourcing, PCBA, inspection and testing under one order. That removes the handoff between a bare-board factory, a component buyer and an assembly house. One team reviews the Gerber or ODB++, stackup, BOM, placement data and test requirements before production.

For standard MCPCB prototypes below 1 m² using standard aluminium, 0.8–2.0 mm board thickness, H/H or 2 oz copper, lead-free HASL, white solder mask, black legend and 0.8 W/(m·K) material, EBest publishes these manufacturing references:

• Single-layer MCPCB: 4 days standard, with a 24-hour fastest option;
• Two-layer MCPCB: 14 days standard, with a 168-hour fastest option;
• Four-layer MCPCB: 21 days standard; expedite timing is reviewed per design.

Copper-base, higher-conductivity, heavy-copper, special-finish, multilayer or custom-test builds need a project schedule. For full PCBA, the standard published reference is 10–12 business days from confirmed files and purchase order, subject to BOM availability and test scope.

The commercial advantage is a quote that can show the complete delivered scope: bare board, components, SMT or THT assembly, AOI, functional test, packing and freight to Spain. This makes the total cost easier to compare with a local bare-board quotation. EBest also provides a free DFM review, so material, isolation, panelisation and assembly risks can be raised before the order is released.

Use the same drawings, quantities and quality requirements when comparing EBest with Metal Core PCB manufacturers in Spain. Then compare the final delivered price and arrival date rather than bare-board price alone.

What Should You Include in a Metal Core PCB RFQ?

A complete RFQ reduces both price padding and schedule surprises. Send the same controlled package to every supplier:

• Gerber or ODB++, drill files and revision-controlled fabrication drawing;
• metal type and alloy, dielectric, finished copper and total thickness;
• required thermal and electrical-isolation performance;
• outline, slots, holes, countersinks, flatness, burr and V-score limits;
• surface finish, solder mask, legend, panelisation and breakaway method;
• electrical, isolation, dimensional and traceability deliverables;
• prototype, pilot and repeat quantities, plus annual demand;
• requested factory dispatch date, delivery address and Incoterm;
• BOM, approved alternates, CPL, assembly drawing and test specification when PCBA is required.

Require the quotation to list deviations and exclusions beside the price. If the supplier proposes a different dielectric, omits a test or starts lead time only after a later approval, you should see that before comparing totals.

FAQs About Metal Core PCB Manufacturers in Spain

Q1: Which Spanish supplier publishes a lead time for aluminium IMS?

A1: Fast PCB states 5 working days for short series and 10 working days for large series. CIPSA publishes a broader PCB prototype service of 24 hours to 5 days, but the requested IMS construction should be confirmed for that service.

Q2: Which companies publish copper IMS capability?

A2: CIRLAN and Maxwell Atlantic list copper as well as aluminium IMS. The quote should still identify the copper base, dielectric, factory and process limits for the part.

Q3: Which supplier publishes double-sided or PTH IMS structures?

A3: CIPSA publishes aluminium IMS options that include double-sided and PTH constructions. Ask for the current capability revision and the isolation method around plated features.

Q4: How should I compare metal core PCB prices?

A4: Compare the same material, quantity, tooling, tests, reports, packing, freight and delivery term. Separate bare-board and PCBA costs so missing work does not make one quote look artificially low.

Q5: What quality records should I request?

A5: Typical records include material identity, electrical-test results, isolation-test results, dimensional inspection, lot traceability and any agreed first-article report. Put required documents in the purchase order.

Q6: Does a short fabrication lead time include delivery to Spain?

A6: Usually not unless the quotation says so. Ask for the clock start, fabrication days, dispatch date, freight method and expected arrival date.

Q7: Can one supplier handle both metal-core PCB and assembly?

A7: Some overseas suppliers, including EBest Circuit, offer metal-core PCB fabrication, component sourcing, PCBA and testing together. The Spanish suppliers reviewed here mainly present bare PCB manufacturing services.

Q8: What files are needed for an accurate quotation?

A8: Send Gerber or ODB++, drills, stackup, fabrication drawing, thermal and isolation requirements, quantity and delivery target. Add BOM, CPL, assembly drawing and test instructions for PCBA.
