PCB Assembly
Seektech’s PCB Assembly: Precision, Speed, and Experience Since 2010
When you’re racing to get a product to market, or need a reliable partner for small-batch runs, not just any PCB assembly service will do. At Seektech, we’ve been perfecting our PCB assembly craft since 2010—15 years of turning designs into functional, reliable boards. Over that time, we’ve learned that your success depends on more than just putting components on a board. It depends on speed, flexibility, and a team that understands the messiness of real-world manufacturing. Let’s start with the basics—what we can build, and how we do it better.
Our PCB Assembly Capabilities：From Flex to Multilayer, We Handle It All
PCB assembly isn’t one-size-fits-all. Some projects need the bendable versatility of flex PCBs; others demand the density of multilayer boards. That’s why we’ve invested in mastering every type. Whether you’re working with traditional rigid PCBs, ultra-thin designs, HDI boards with microvias, rigid-flex hybrids, or FPCs that twist and fold, our team has seen it all. We’ve assembled these varied boards for clients across industries, and that experience shows in the little details—like knowing how to reinforce a flex PCB’s fold line or align a 20-layer board’s vias for perfect signal flow.
Flex PCB assembly is a good example of where experience matters. Anyone can solder components to a rigid board, but flex PCBs? They need a steady hand and a knack for anticipating how bends will stress solder joints. We’ve assembled flex circuits for everything from wearable fitness trackers to medical devices that wrap around joints—so we know to reinforce fold lines and use solder masks that won’t crack under repeated motion.
Multilayer PCB assembly is another area where we shine. With 20+ layer boards, alignment between layers can make or break signal integrity. Our in-house engineers work directly with your design team to review stack-ups, ensuring blind and buried vias are placed for optimal performance. Honestly, it’s not just assembly—it’s partnership.
Our Impressive Scale: 120 Experts, 8 SMT Lines, and the Tools to Handle It All
We’re not a small shop—and that’s a good thing. Our 120-strong team includes engineers, technicians, and quality specialists, each with an average of 7 years in PCB assembly. They’re backed by 8 state-of-the-art SMT lines, all equipped with FUJI NXTIII pick-and-place machines. These aren’t just any machines—they can place 03015 components (that’s smaller than a grain of rice) with pinpoint accuracy, ensuring even the densest boards come out clean.
But precision isn’t enough. That’s why every SMT line has nitrogen reflow ovens. Nitrogen reduces oxidation during soldering, which means stronger, more reliable joints—critical for high-precision electronics where a weak solder could spell disaster. For through-hole components, we’ve got a dedicated DIP line with wave soldering, and when your project needs final assembly into enclosures? Our 2 box building lines handle that, too, turning bare boards into ready-to-use devices.
This scale lets us tackle everything from tiny medical sensors to rugged industrial power supplies. And because we’re big enough to invest in top-tier tools but small enough to care about your project, you get the best of both worlds: efficiency without the impersonal feel.
Quick Turn Assembly: 24-Hour Delivery Isn’t a Gimmick
Let’s talk about speed. We get it—prototypes fail, last-minute design tweaks happen, and sometimes you need a batch of boards yesterday. That’s why we built our quick turn assembly process to deliver results, not excuses. If all materials (components, PCBs, specs) are locked in, we can turn around assemblies in as little as 24 hours.
How do we pull that off? It starts with our own PCB factory. Having PCBs made in-house means we don’t wait on external suppliers—if a design needs a last-minute PCB adjustment, we can spin a new batch while your components are being prepped. Add in our stable network of electronic component suppliers (300+ trusted partners, built over 15 years), and we rarely hit snags with hard-to-find parts.
This isn’t just about speed, though. Quick turn assembly should never mean cutting corners. We still run every board through AOI and SPI checks, even on rush orders. Because what’s the point of a fast delivery if the board fails testing?
Full Turnkey Assembly: We Handle the Headaches, So You Don’t Have To
Sourcing components, managing BOMs, chasing down rare ICs—these are the parts of manufacturing that eat up your time. Our full turnkey assembly service takes that weight off your shoulders. Hand us your Gerbers and a bill of materials, and we’ll handle everything: ordering components (even obsolete ones, thanks to our vintage parts network), building the PCBs in-house, assembling, testing, and shipping.
Partial turnkey? We do that too. If you’ve already got some components in stock, we’ll integrate them seamlessly with the ones we source. The goal is simple: let you focus on designing great products, not logistics.
What makes our turnkey service different? We’re not just a middleman. Our buyers work directly with your engineers to suggest alternatives when parts are backordered, and our in-house PCB factory lets us align board production with assembly schedules—so there’s no waiting for PCBs to arrive before we start building. It’s a level of coordination most assembly shops can’t match, because they don’t own the entire process.
Beyond Assembly: Circuit Board Conformal Coating, IC Programming, and More
A great PCB assembly partner does more than solder. They think about how your board will live in the real world. That’s why we offer a full suite of value-added services to protect your investment.
Circuit board conformal coating is a big one. Whether you need acrylic for moisture resistance, silicone for flexibility, or urethane for chemical protection, we apply it evenly—no bubbles, no thin spots. It’s not just for industrial gear, either; medical devices in humid operating rooms or outdoor sensors facing rain? They rely on this coating to last.
Then there’s the nitty-gritty stuff: IC programming (we flash firmware during assembly so your boards arrive ready to use), BGA rework (our techs can replace a misaligned BGA without damaging surrounding components), connector crimping (automated stations ensure every pin has consistent force), and even laser marking for traceability. Need a shielded enclosure to block EMI? We’ll install it.
Honestly, these services aren’t extras—they’re the difference between a board that works in the lab and one that survives in the field.
Testing That Leaves No Room for Doubt
We don’t just build boards—we prove they work. Our testing suite is comprehensive, starting with SPI (Solder Paste Inspection) to catch uneven deposits before components hit the board. FAI (First Article Inspection) ensures the first run matches your specs, so there are no surprises later. AOI scans every solder joint for bridges or cold joints, while X-ray dives into BGAs and QFNs to check for hidden voids.
For functional validation, we use FCT (Functional Test) and ICT (In-Circuit Test) to make sure every circuit behaves as designed. And when your product needs to stand the test of time? Our burn-in test chambers run assemblies through temperature cycles and voltage stress, simulating years of use in weeks. Need something custom? We’ll design a test plan around your unique requirements—because your device isn’t “one-size-fits-all,” and neither should its testing.
No MOQ? No Problem. We Love Small Batches as Much as Large Runs
Here’s a secret most assembly shops won’t admit: small batches are hard. They’re time-consuming, and the math on profitability doesn’t always add up. But we built our process to thrive on them. Whether you need 10 prototypes, 500 units for a beta test, or 5,000 for a regional launch, we don’t charge a premium for small orders. No MOQ, no hidden fees—just the same attention to detail, regardless of size.
Why? Because we remember what it’s like to be a startup, or an engineer with a great idea but limited funds. Small batches are where innovations start, and we want to be there when you’re just getting off the ground. Plus, our flexible lines mean switching between small and large runs is seamless—no retooling delays, no headaches.
Our PCB Factory: The Secret to Consistent Quality
You can’t have great PCB assembly without great PCBs. That’s why we own our own PCB manufacturing facility—so we control quality from the bare board up. Our factory produces everything from simple single-layer PCBs to complex 20-layer multilayers, with tight tolerances on line width (down to 3mil) and hole precision.
This in-house production isn’t just about quality—it’s about speed, too. When your assembly order comes in, we don’t wait for a third-party PCB supplier. We can start building boards the same day, aligning production with your assembly schedule to cut lead times by weeks. It’s a level of coordination that external suppliers just can’t match.
