WHO WE MANUFACTURE FOR
Built for startups and growing brands — not just large OEMs
Whether you're building your first batch of 50 units or scaling to monthly runs of 5,000 — we structure our process around your volume, your timeline, and your quality requirements.
You have a validated prototype and need your first real build
First CM engagement · Prototype to pilot run
TYPICAL SITUATION
HARDWARE STARTUP
Your breadboard or assembled prototype works. You've validated the concept and you're ready to move beyond hand-built units. You need a CM who will take a small first order seriously and help you build a process for scale.
Whichever stage you're at, our manufacturing process is the same — IPC-A-610 Class 2, full AOI inspection, documented first articles, and proactive communication throughout. The difference is the scale we calibrate it to.

SUPPLY MODELS
Turnkey, consignment, or partial — we support all three
The supply model determines who sources your components and how pricing is structured. Understanding the difference helps you choose the right approach for your project — and helps us quote accurately from the start.
Turnkey Manufacturing
You provide files. We source everything, build everything, and deliver finished boards.
WHO DOES WHAT
You provide Gerber files, BOM, and assembly drawings. We source all components, procure the PCB, and manage the complete build — component ordering, incoming inspection, kitting, assembly, test, and shipping.
BEST FOR
Hardware startups and founders without existing supply chain relationships. Products where Shenzhen market sourcing delivers the best combination of price and availability. First production runs where the client wants to minimize operational complexity.
PRICING STRUCTURE
Assembly cost + component cost + sourcing fee. Component cost is quoted separately from assembly — you receive a line-by-line BOM cost breakdown before we order anything. No hidden margins.
TYPICAL SCENARIO
A hardware startup with a validated prototype sends us their design files. We review, quote the complete build cost including components, and manage everything through to delivered boards. The client's only job is to review DFM, approve the BOM cost, and accept delivery.
Choose this if...:
You don't have existing component supplier relationships, you want to minimize procurement complexity, or you want Shenzhen market pricing without managing a supply chain yourself.
Partial Consignment
You supply specific components. We source everything else and manage the complete build.
WHO DOES WHAT
You supply the components that matter most to you — proprietary parts, specific supplier-qualified components, long-lead-time items, or anything where you need direct supply chain control. We source all remaining components at Shenzhen market pricing.
BEST FOR
Established brands with existing supplier relationships for key components. Products with proprietary or custom parts that can't be open-market sourced. Projects where some components have strategic supplier qualifications or regulatory traceability requirements.
PRICING STRUCTURE
Assembly cost + our sourcing cost for non-supplied components + kitting and incoming inspection for your supplied components. Your supplied components are not marked up — you own them. We charge a small incoming inspection and kitting fee per component line.
TYPICAL SCENARIO
A product brand supplies their custom display module and a specific PMIC from their qualified supplier. We source all standard passive components, connectors, and ICs from Shenzhen. The client controls the supply of their two most important components while benefiting from our procurement efficiency for the rest.
Choose this if...:
You have specific supplier relationships for key components, you have proprietary or custom parts that must come from a specific source, or you want a balance of supply chain control and procurement convenience.
Full Consignment
You supply all components. We provide assembly, test, and inspection only.
WHO DOES WHAT
You source and supply every component on the BOM — PCB, all SMT and through-hole components, any hardware. We provide the assembly service only — line setup, SMT placement, soldering, AOI, functional test, and packaging. We do not source any components on your behalf.
BEST FOR
Established OEMs and product companies with mature supply chain relationships. Products with strict AVL requirements where all components must come from specific qualified suppliers. High-volume production where the client negotiates direct component pricing. Companies with existing inventory they need assembled.
PRICING STRUCTURE
Assembly cost only. No component procurement, no sourcing fees. Pricing is based on board complexity, component count, and volume. You bear all component procurement risk — shortages or quality failures in your supplied components are your responsibility to resolve.
TYPICAL SCENARIO
A product manager at an established electronics brand has existing supplier agreements for all components and a mature BOM. Their preferred assembly partner in Europe has capacity issues. They ship kitted components to our Shenzhen facility — we assemble, test, and ship finished boards back to their distribution center.
Choose this if...:
You have established supply chain relationships for all components, your components must come from specific qualified suppliers, you have existing component inventory to be assembled, or you want assembly-only pricing with no sourcing involvement from us.

QUALITY & COMPLIANCE
Built to IPC standards with full production traceability
Every build runs through a defined quality system — inspection at every stage, documented results per unit, and compliance with the standards your product needs to reach market. Here's exactly what that looks like.
OUR QUALITY SYSTEM
ASSEMBLY ACCEPTABILITY STANDARD
IPC-A-610 Class 2
IPC-A-610 is the globally recognized standard for the acceptability of electronic assemblies. Class 2 covers general electronics products — the standard applied to the vast majority of consumer, commercial, and industrial electronics. It defines acceptance criteria for solder joints, component placement, cleanliness, and cosmetic condition.
SOLDERING STANDARD
IPC J-STD-001
IPC J-STD-001 defines the requirements for soldering electrical and electronic assemblies — covering materials, methods, and verification criteria for both lead-free and leaded solder processes. Our processes are qualified to J-STD-001 Class 2, with Class 3 available alongside IPC-A-610 Class 3 for high-reliability builds.
PCB FABRICATION STANDARD
IPC-6012 Class 2
IPC-6012 covers the qualification and performance specification for rigid PCBs. Class 2 is the standard for general electronics. We verify PCB incoming quality against IPC-6012 before any boards enter the assembly process — incoming inspection is not optional.
REWORK & REPAIR STANDARD
IPC-7711/7721
Rework and repair — when required — is performed to IPC-7711/7721 standards. All rework is documented with the reason, the method used, and the technician responsible. Reworked units are retested to the same functional test protocol as original builds. Rework is never hidden — it appears in the build record for every unit.
CERTIFICATIONS & COMPLIANCE
RoHS 2.0 & 3
Fully compliant with RoHS 2.0 (2011/65/EU) and RoHS 3.0 (2015/863/EU) for all restricted substances.
ISO 9001:2015
Certified Quality Management System ensuring consistent process control and continuous improvement.
EPA-compliant ESD control program across all production and inspection areas.
ESD Protected
All materials and processes coomply with REACH regulation (EC) No. 1907/2006.

WHY PEAKINGTECH
What makes us different from a standard contract manufacturer
Most contract manufacturers are optimized for volume — repeat orders, stable BOMs, and clients who know exactly what they want. We're optimized for something different: products that are being manufactured for the first time, by teams that are doing this for the first time.
NPI-first mindset — not a volume CM tolerating small orders
Most contract manufacturers make their money on repeat orders of stable products at high volume. NPI builds — first articles, small batches, design changes mid-run — are disruptions to their process. They tolerate them because they hope to win the volume business. We've structured our entire operation around the opposite priority: new products that have never been manufactured before, for teams who've never done this before.
"We'd tried two other contract manufacturers before Peakingtech. The first didn't respond to our NPI inquiry at all. The second replied, quoted us, then went silent for three weeks. With Peakingtech, we had a DFM report in two days and a first article in three weeks. That's the whole point — they actually want to build your product."

The most common reason manufacturing relationships fail is communication breakdown. Not quality failure, not missed deadlines — communication. A client who can't get a clear answer to a question, who receives updates only when they chase, who discovers problems after the fact rather than in real time, loses confidence in their manufacturer regardless of the quality of the physical output.
Integrated electronics, enclosure, and sourcing — under one roof
Most contract manufacturers assemble PCBs. If you need an enclosure, you find an injection molder. If you need components sourced, you find a sourcing agent. If you need a PCB design reviewed, you find an NPI engineer. The coordination between these separate vendors — files passing between them, schedules that don't align, quality standards that don't match — is where most NPI projects lose time and cost.
Transparent at every stage — no black-box manufacturing
Electronics manufacturing in China has a reputation for opacity: you send files, you wait, you receive boards, and you hope they're right. If they're not, you struggle to understand what went wrong because you have no visibility into what happened during production.
