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.<\/p>\n<p>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.<\/p>\n<figure style=\"margin:28px auto;max-width:600px\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/09\/metal-core-pcb-manufacturers-spain-hero.jpg\" width=\"600\" height=\"400\" alt=\"Metal Core PCB manufacturers in Spain, aluminium and copper IMS panels in a quality inspection lab\" style=\"display:block;width:100%;max-width:600px;height:auto;margin:auto\"><\/figure>\n<h2 style=\"font-size:1.6rem;line-height:1.3;margin:2em 0 .7em;border-left:4px solid #2498e9;border-bottom:0;padding-left:12px;background:#fff\"><span class=\"ez-toc-section\" id=\"Who_Are_the_Main_Metal_Core_PCB_Manufacturers_in_Spain\"><\/span>Who Are the Main Metal Core PCB Manufacturers in Spain?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>CIRLAN, Fast PCB, Maxwell Atlantic and CIPSA Circuits all identify finished PCB manufacturing operations in Spain and publish an IMS or metal-core offer.<\/strong> Their process scope and delivery visibility are not the same.<\/p>\n<div class=\"table-responsive\" style=\"width:100%;margin:22px 0\">\n<table style=\"width:100%;max-width:100%;table-layout:fixed;border-collapse:collapse;border:1px solid #111;background:#fff\">\n<thead>\n<tr>\n<th style=\"border:1px solid #111;padding:10px;background:#fff;text-align:left\">Company<\/th>\n<th style=\"border:1px solid #111;padding:10px;background:#fff;text-align:left\">Process capability<\/th>\n<th style=\"border:1px solid #111;padding:10px;background:#fff;text-align:left\">Lead-time information<\/th>\n<th style=\"border:1px solid #111;padding:10px;background:#fff;text-align:left\">Service scope<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td data-label=\"Company\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\"><strong>CIRLAN<\/strong><br \/>Urnieta, Gipuzkoa<\/td>\n<td data-label=\"Process capability\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\">Single-sided aluminium and copper IMS;

Standard copper is 35 or 70 \u00b5m; 105 \u00b5m is listed as special production. The same table gives track and spacing, drill, routing, scoring, panel-size and finish limits.<\/p>\n<p>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.<\/p>\n<p>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.<\/p>\n<h2 style=\"font-size:1.6rem;line-height:1.3;margin:2em 0 .7em;border-left:4px solid #2498e9;border-bottom:0;padding-left:12px;background:#fff\"><span class=\"ez-toc-section\" id=\"Fast_PCB\"><\/span>Fast PCB<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong><a href=\"https:\/\/www.fastpcb.com\/servicios\/circuitos-impresos-simple-cara-aluminio-ims-pcb\/\">Fast PCB<\/a> is the easiest supplier in this group to assess when the project is a conventional single-sided aluminium board and delivery speed matters.<\/strong> Its IMS page states 5 working days for short series, 10 working days for large series and 100 m\u00b2\/day of production capacity.<\/p>\n<p>The published process range covers aluminium bases from 0.8 to 3.2 mm, copper from 35 to 105 \u00b5m, a maximum delivery format of 544 \u00d7 390 mm, chemical tin, CNC routing and V-scoring. That is enough to reject obvious mismatches before engineering spends time on an RFQ.<\/p>\n<p>Fast PCB also describes a <a href=\"https:\/\/www.fastpcb.com\/\">metallographic laboratory<\/a> 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.<\/p>\n<p>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.<\/p>\n<h2 style=\"font-size:1.6rem;line-height:1.3;margin:2em 0 .7em;border-left:4px solid #2498e9;border-bottom:0;padding-left:12px;background:#fff\"><span class=\"ez-toc-section\" id=\"Maxwell_Atlantic\"><\/span>Maxwell Atlantic<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong><a href=\"https:\/\/maxwellatlantic.com\/company-2\/?lang=en\">Maxwell Atlantic<\/a> is relevant when a buyer wants broad in-house PCB process control as well as an aluminium or copper IMS option.<\/strong> 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.<\/p>\n<p>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.<\/p>\n<p>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.<\/p>\n<h2 style=\"font-size:1.6rem;line-height:1.3;margin:2em 0 .7em;border-left:4px solid #2498e9;border-bottom:0;padding-left:12px;background:#fff\"><span class=\"ez-toc-section\" id=\"CIPSA_Circuits\"><\/span>CIPSA Circuits<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong><a href=\"https:\/\/www.cipsacircuits.com\/portfolio-item\/circuitos-impresos-ims\/\">CIPSA Circuits<\/a> publishes the widest aluminium IMS structure range among the four companies compared here.<\/strong> 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 \u00b5m copper and 0.15 mm line and spacing.<\/p>\n<p>CIPSA states on its <a href=\"https:\/\/www.cipsacircuits.com\/en\/quality-2\/\">quality page<\/a> that it performs rigorous controls throughout manufacturing and retains traceability for raw materials and test results. Its <a href=\"https:\/\/www.cipsacircuits.com\/fabricacion-de-prototipos\/\">general prototype service<\/a> 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.<\/p>\n<p>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.<\/p>\n<h2 style=\"font-size:1.6rem;line-height:1.3;margin:2em 0 .7em;border-left:4px solid #2498e9;border-bottom:0;padding-left:12px;background:#fff\"><span class=\"ez-toc-section\" id=\"How_Do_These_Metal_Core_PCB_Manufacturers_Compare\"><\/span>How Do These Metal Core PCB Manufacturers Compare?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>Do not compare four unit prices until every quote covers the same material, tests, quantity, delivery point and service scope.<\/strong> A cheaper line item can become the expensive choice once tooling, certificates, freight or a second supplier for assembly is added.<\/p>\n<div class=\"table-responsive\" style=\"width:100%;margin:22px 0\">\n<table style=\"width:100%;max-width:100%;table-layout:fixed;border-collapse:collapse;border:1px solid #111;background:#fff\">\n<thead>\n<tr>\n<th style=\"border:1px solid #111;padding:10px;background:#fff;text-align:left\">Buyer concern<\/th>\n<th style=\"border:1px solid #111;padding:10px;background:#fff;text-align:left\">What to compare<\/th>\n<th style=\"border:1px solid #111;padding:10px;background:#fff;text-align:left\">What the quote should state<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td data-label=\"Buyer concern\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\"><strong>Quality<\/strong><\/td>\n<td data-label=\"What to compare\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\">IMS material identity, electrical test, isolation test, dimensional inspection, traceability and non-conformance handling<\/td>\n<td data-label=\"What the quote should state\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\">Named material and factory, test method, sampling or 100% scope, reports supplied and acceptance criteria<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Buyer concern\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\"><strong>Total price<\/strong><\/td>\n<td data-label=\"What to compare\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\">Unit price at prototype and repeat quantities, tooling, test reports, special material, packing, freight and import charges<\/td>\n<td data-label=\"What the quote should state\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\">Separate line items, quotation validity, quantity breaks, Incoterm and currency<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Buyer concern\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\"><strong>Lead time<\/strong><\/td>\n<td data-label=\"What to compare\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\">DFM response, material procurement, fabrication, test, packing and transit<\/td>\n<td data-label=\"What the quote should state\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\">Clock start, working days, engineering-hold rule, dispatch date and arrival responsibility<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Buyer concern\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\"><strong>Service scope<\/strong><\/td>\n<td data-label=\"What to compare\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\">Bare PCB only or PCB plus component sourcing, assembly, inspection, functional test and shipping<\/td>\n<td data-label=\"What the quote should state\" style=\"border:1px solid #111;padding:10px;background:#fff;overflow-wrap:break-word\">Exact owner for each stage, included deliverables and warranty or failure-analysis route<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>Ask for two dates: the factory dispatch date and the expected delivery date at your site.

One team reviews the Gerber or ODB++, stackup, BOM, placement data and test requirements before production.<\/p>\n<p>For standard MCPCB prototypes below 1 m\u00b2 using standard aluminium, 0.8\u20132.0 mm board thickness, H\/H or 2 oz copper, lead-free HASL, white solder mask, black legend and 0.8 W\/(m\u00b7K) material, EBest publishes these manufacturing references:<\/p>\n<ul>\n<li><strong>Single-layer MCPCB:<\/strong> 4 days standard, with a 24-hour fastest option;<\/li>\n<li><strong>Two-layer MCPCB:<\/strong> 14 days standard, with a 168-hour fastest option;<\/li>\n<li><strong>Four-layer MCPCB:<\/strong> 21 days standard; expedite timing is reviewed per design.<\/li>\n<\/ul>\n<p>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\u201312 business days from confirmed files and purchase order, subject to BOM availability and test scope.<\/p>\n<p>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.<\/p>\n<p>Use the same drawings, quantities and quality requirements when comparing EBest with <a href=\"https:\/\/www.bestpcbs.com\/blog\/metal-core-pcb-manufacturers-in-spain\/\">Metal Core PCB manufacturers in Spain<\/a>. Then compare the final delivered price and arrival date rather than bare-board price alone.<\/p>\n<h2 style=\"font-size:1.6rem;line-height:1.3;margin:2em 0 .7em;border-left:4px solid #2498e9;border-bottom:0;padding-left:12px;background:#fff\"><span class=\"ez-toc-section\" id=\"What_Should_You_Include_in_a_Metal_Core_PCB_RFQ\"><\/span>What Should You Include in a Metal Core PCB RFQ?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>A complete RFQ reduces both price padding and schedule surprises.<\/strong> Send the same controlled package to every supplier:<\/p>\n<ul>\n<li>Gerber or ODB++, drill files and revision-controlled fabrication drawing;<\/li>\n<li>metal type and alloy, dielectric, finished copper and total thickness;<\/li>\n<li>required thermal and electrical-isolation performance;<\/li>\n<li>outline, slots, holes, countersinks, flatness, burr and V-score limits;<\/li>\n<li>surface finish, solder mask, legend, panelisation and breakaway method;<\/li>\n<li>electrical, isolation, dimensional and traceability deliverables;<\/li>\n<li>prototype, pilot and repeat quantities, plus annual demand;<\/li>\n<li>requested factory dispatch date, delivery address and Incoterm;<\/li>\n<li>BOM, approved alternates, CPL, assembly drawing and test specification when PCBA is required.<\/li>\n<\/ul>\n<p>Require the quotation to list deviations and exclusions beside the price.

CIPSA publishes a broader PCB prototype service of 24 hours to 5 days, but the requested IMS construction should be confirmed for that service.<\/p>\n<p><strong>Q2: Which companies publish copper IMS capability?<\/strong><\/p>\n<p>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.<\/p>\n<p><strong>Q3: Which supplier publishes double-sided or PTH IMS structures?<\/strong><\/p>\n<p>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.<\/p>\n<p><strong>Q4: How should I compare metal core PCB prices?<\/strong><\/p>\n<p>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.<\/p>\n<p><strong>Q5: What quality records should I request?<\/strong><\/p>\n<p>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.<\/p>\n<p><strong>Q6: Does a short fabrication lead time include delivery to Spain?<\/strong><\/p>\n<p>A6: Usually not unless the quotation says so. Ask for the clock start, fabrication days, dispatch date, freight method and expected arrival date.<\/p>\n<p><strong>Q7: Can one supplier handle both metal-core PCB and assembly?<\/strong><\/p>\n<p>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.<\/p>\n<p><strong>Q8: What files are needed for an accurate quotation?<\/strong><\/p>\n<p>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.<\/p>\n<h2 style=\"font-size:1.6rem;line-height:1.3;margin:2em 0 .7em;border-left:4px solid #2498e9;border-bottom:0;padding-left:12px;background:#fff\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>The best supplier depends on the exact structure and delivery model.<\/strong> CIRLAN publishes detailed single-sided aluminium and copper IMS limits. Fast PCB provides the clearest stated series lead times for single-sided aluminium. Maxwell Atlantic offers broad in-house PCB processing and traceability. CIPSA publishes aluminium IMS structures that include double-sided and PTH options.<\/p>\n<p>Compare quality evidence, total delivered cost, clock start, dispatch date and service scope before choosing.
