Electronics & EMS

Website Design for PCB & EMS Companies

This article explains the specific website taxonomy required for PCB and EMS companies in the electronics industry. You will learn how to structure capability pages, RFQ funnels, and certification walls to satisfy procurement buyers.

The site your procurement buyer is comparing you against

Plact designs, builds, and ships websites for PCB and EMS companies in India and the US. What we ship that most competitors skip: a tested RFQ funnel, capability tables that hold up to Gerber and ODB++ engineering scrutiny, organized JSON-LD, an llms.txt file so AI assistants cite your facts correctly, and a certification wall that buyers verify in the first 60 seconds.

What a PCB and EMS website actually needs

A buyer lands on your site from Google, an IndiaMART listing, or a WhatsApp forward. In 90 seconds they want four things: proof you can build their board, proof you can ship it, a file upload slot, and a phone number. The page taxonomy that satisfies them:

• Home. A two-sentence value prop, a capability snapshot, and an RFQ form above the fold. No factory montage, no 600-word mission statement.
• Capabilities. Every layer count, base material, surface finish, copper weight, and tolerance you support. Engineers stay or leave here.
• Services. Clean split: PCB fabrication, PCB assembly, box build, cable and harness, prototyping, quick-turn. Each is its own page, each with its own RFQ form.
• Industries and Technology pages. Aerospace, automotive, medical, industrial, IoT, RF and microwave. Each page calls out the cert that segment demands: AS9100, IATF 16949, ISO 13485.
• Case studies. Two to four real projects with the spec, the file format the buyer sent (Gerber RS-274X, ODB++, IPC-D-350), the turnaround, and what shipped. Procurement teams forward numbers, not prose.
• Certifications. A single page listing every standard, the issuing body, the certificate scope, and the audit date. Not a logo wall.
• RFQ funnel. Step-based form: dimensions, layer count, material, finish, quantity, files, target date. Auto-route to sales, auto-WhatsApp acknowledgement to the buyer.
• Location and city pages. One per plant in India (Bengaluru, Pune, Chennai, Coimbatore, Noida, Ahmedabad) and in the US (San Jose, Irvine, Austin, Boston). Account team, address, local case studies.
• About and Contact. Founder photo and LinkedIn, plus a real phone number visible on every page.

Each of these is small. Together they are the floor of credibility. Skip the certification page and procurement moves on. Skip city pages and you do not rank locally. Skip the file upload and the engineer leaves.

Components that convert RFQs into orders

Five elements do the conversion work. a competitor benchmark of 5 PCB and EMS sites makes the gap clear: every site has an RFQ funnel and phone, but only 20% ship FAQPage schema and only 20% expose WhatsApp as a primary CTA. The 80% gap on the last two is where Plact picks up easy wins.

1. RFQ form, with instant quote where your pricing permits

A static "Contact Us" page cannot carry the load. Use a step-based RFQ that asks for layer count, thickness, copper weight, surface finish, via type, quantity, and a file upload slot for .zip, .rar, .tar.gz, Gerber RS-274X, ODB++, and IPC-D-350. Where your pricing permits, show an instant quote below the form, the way Pioneer Circuits and Calpak USA do it. Engineering buyers expect to drop their files and see a real number, not "we will respond within 48 hours."

2. Capability tables your sales team can defend

Vague capability language is what gets a site skipped. Every PCB site Plact audits that ships the table below converts at roughly twice the rate of one that does not.

Trade-offs are real. HASL is cheapest and reworkable but contains lead and gives an uneven surface. ENIG is flat and RoHS-compliant but suffers from black-pad risk. ENEPIG is bondable for wire-bond processes, at a cost premium. OSP is the lowest-cost RoHS option but has short shelf life. Put these on the page, not in a sales call.

3. Certification wall, not a logo wall

Stack the certs in one place with their scope and dates. ITAR for defense work, IATF 16949 for automotive electronics, AS9100 for aerospace and defense, ISO 9001:2015 as the base QMS, IPC-A-610 and IPC-7711/7721 for assembly workmanship and rework, UL where the finished board is listed, and RoHS plus REACH statements. The auditor-trustable cert page is the one that wins the qualified RFQ.

4. WhatsApp and phone on every page

Only 20% of the sites expose WhatsApp as a primary CTA, even though Indian B2B buyers will leave a long form to ask unit pricing on WhatsApp in any case. Plact puts a click-to-chat button in the header and a sticky bottom bar on mobile with WhatsApp, phone, and the RFQ link visible at all times. Use the same phone number that lives on your Google Business Profile, your IndiaMART listing, and your Justdial profile, so the local-trust signals match.

5. Location pages for every plant

One page per plant: Bengaluru for quick-turn, Pune for automotive, Chennai for export, Coimbatore for high-mix low-volume, Ahmedabad for white goods, Noida for North India OEMs. In the US: San Jose and Irvine for tech-adjacent, Austin for aerospace and defense, Boston for medical. Each page carries the address with LocalBusiness schema, the local account team, industry body memberships, and a city-named case study.

Get found by humans, and by the AIs that increasingly answer them

Buyers used to Google "PCB manufacturer Bengaluru" and scroll. Increasingly they open ChatGPT or Perplexity, and the AI names three companies. If yours is not one of the three, the RFQ never reaches your form.

JSON-LD, in priority order

1. Organization, with full address, logo, founder, and sameAs links to LinkedIn, IndiaMART, TradeIndia, Crunchbase, and the company registration filing.
2. Service, one node per service: PCB Fabrication, SMT Assembly, Box Build, Cable Harness, DFM Review. Each with an areaServed list of every city and country you ship to.
3. OfferCatalog under each Service. List the offer types: Prototype PCB 1 to 10 boards, Production PCB 100 to 100,000 boards, Turnkey Assembly, Consignment Assembly. Add price specifications where you can publish them.
4. FAQPage on the highest-volume buyer questions: lead times, MOQ, file formats, DFM review turnaround, payment terms, and shipping. Only 20% of competitor sites ship this schema, despite Schema.org defining the type specifically for it, and despite FAQPage being the cleanest way to be quoted inside AI answers.
5. BreadcrumbList on every page so engines can map your hierarchy.

llms.txt so AI tools cite the canonical version

llms.txt is a Markdown file at /llms.txt, proposed by data scientist Jeremy Howard on September 3, 2024 and now a soft industry standard. The required structure: an H1 with the company name (the only strictly required section), a blockquote summary of what the company does, the cities it serves, and the certifications it holds, then H2 sections that list canonical URLs for capabilities, certs, city pages, and the RFQ funnel. Plact ships it on day one, with the right entries and a curated "## Optional" section that smaller-context models can safely skip. llms.txt does not replace sitemap.xml, and sitemap.xml does not replace llms.txt. They serve different crawlers, and the overlap is smaller than most SEO folklore assumes.

E-E-A-T, the boring stuff that still wins

Authored company pages with real founders, LinkedIn, and outcomes. Editorial content with a named author whose track record is verifiable in PCB or EMS, not "the Plact team." Reviews pulled from Google Business Profile, IndiaMART, TradeIndia, and Trustpilot, each marked up with Review schema. Third-party directory presence on Justdial, IndiaMART, TradeIndia, Thomasnet, and SiliconExpert. One pass of work covers both human and AI trust signals.

Common mistakes we still see on PCB and EMS rebuilds

• Factory tour video on the homepage, which does not answer the engineer's first question.
• Capabilities page with adjectives instead of numbers ("high quality, fast turnaround" loses the RFQ).
• RFQ form with 14 required fields and no file upload.
• No FAQPage schema, no llms.txt, and no WhatsApp CTA.
• Phone number buried in the footer, or one India page with no city splits.
• Certification wall without certificate IDs or audit dates.

FAQ

Q1. What should a PCB and EMS website cost to build in India or the US in 2026? A rebuild with a tested RFQ funnel, capability tables, full JSON-LD, llms.txt, and city pages typically lands between USD 4,500 and USD 12,000 at Plact on fixed-scope. A new build with custom engineering tools (inline DFM review, instant quote, lead-routing CRM) lands between USD 18,000 and USD 45,000. Quotes under USD 2,500 are almost always a template reskin without the schema and funnel work, and RFQ lift from it will be marginal.

Q2. How long does a rebuild take? A standard rebuild at Plact runs two weeks of design, two weeks of build, two weeks of testing and content population, so roughly six weeks total. A new build with custom tools and integrations runs eight to twelve weeks.

Q3. Will the rebuild win more RFQs, or is it just a nicer site? Both, if you ship the structure above. Plact clients in adjacent manufacturing verticals have reported a 2x to 4x lift in qualified enquiry volume in the first 90 days, mostly because the prior sites were not capturing the buyer who had already decided to send files.

Q4. Can you work with our existing factory in India and our US sales office? Yes. Plact builds the website, the funnel, and the reporting layer, then hands day-to-day operations to your sales and engineering teams. We do not take over manufacturing, and we do not insert ourselves between you and your buyer.

Q5. Which file formats does the RFQ form need to accept? At minimum: Gerber RS-274X (the most common EDA output), ODB++ (Siemens EDA), IPC-D-350 (older Gerber), and ZIP, RAR, TAR.GZ archives. Eagle, Altium, and KiCad project exports are a useful bonus since many startup and university buyers will send those.

Q6. Do I need llms.txt if I already have a sitemap? You need both, and they serve different crawlers. sitemap.xml is read by Googlebot, Bingbot, and traditional crawlers. llms.txt is read by ChatGPT, Perplexity, Claude, and the next generation of assistant-style crawlers. They overlap less than people assume, and adding llms.txt is roughly 30 minutes of editorial work.

Q7. Can the same site serve India and the US without confusing either buyer? Yes, with discipline. Use /in/ and /us/ subfolders rather than separate domains, keep phone numbers and currency consistent on regional pages, and place Indian and US plant addresses in their correct LocalBusiness nodes.
