PCB Manufacturing Capabilities Built for Every Application
Velo Circuits focuses on producing mid- to high-end PCBs and provides PCB manufacturing services ranging from prototyping to small- and medium-batch production.
We mainly focus on high-end PCB types: 4-60 layer multilayer PCBs that can handle complex circuits; high-frequency PCBs/RF PCBs with signal integrity for RF and microwave applications; high-speed PCBs with controlled impedance suitable for fast data processing; and heavy copper/thick copper PCBs that can carry high current and high-power electronic devices.
Full-Service PCB Assembly — Prototype, SMT/THT, and Turnkey Solutions
Velo Circuits delivers end-to-end PCB assembly services with a clear focus on quality, flexibility, and fast turnaround. We support everything from rapid prototyping to small- and medium-batch production, combining automated precision with experienced workmanship.
We cover the full assembly spectrum: turnkey PCB assembly with complete component procurement and box-build integration; quick-turn prototype assembly to validate your designs before scaling; high-precision SMT assembly down to 0201 and fine-pitch BGA; and reliable through-hole (THT) assembly for connectors, transformers, and high-power components. Our lines also support mixed SMT/THT processes for boards that demand both technologies.
Manufacturing & Assembly Technologies You Can Rely On
Our in-house capabilities are built around automated, data-driven processes that connect PCB fabrication and assembly into one controlled workflow. This includes laser drilling and controlled impedance processing, fully automated SMT lines with nitrogen reflow, selective wave soldering for mixed-technology boards, and a complete inspection chain — AOI, SPI, X-ray, flying probe, ICT, and functional testing. For boards operating in harsh environments, we apply conformal coating inline. Every step is designed to deliver consistent quality from bare board to finished box-build.

PCB Manufacturing & Assembly FAQs
Q: What types of PCB manufacturing and assembly services does Velo Circuits offer?
A: Velo Circuits is a full-service PCB manufacturer and PCB assembly company covering the entire process from bare board fabrication to finished box-build. Our PCB manufacturing spans HDI, multilayer (up to 60 layers), RF/high-frequency, heavy copper, and high-speed controlled-impedance boards. On the assembly side, we provide turnkey PCB assembly, quick-turn prototyping, and precision SMT/THT mixed assembly — all under one roof.
Q: Can you handle complex, high-reliability PCBs for automotive or RF applications? Control systems?
A: Yes. We specialize in mid- to high-end PCBs built for demanding environments. That includes automotive-grade heavy copper PCBs, RF/ microwave boards with tight signal integrity requirements, and high-speed digital boards with precise impedance control. Our ISO 9001 and IATF 16949 certifications mean every board is produced in a quality-managed, traceable process.
Q: Do you support low-volume prototyping and quick-turn PCB assembly?
A: Absolutely. We run dedicated prototype lines for both PCB fabrication and PCB assembly, supporting low-volume orders with no minimum quantity requirements for most technologies. Our quick-turn prototype assembly service can deliver functional boards in as fast as 7 days, helping you validate designs before scaling.
Q: What certifications and inspection processes ensure quality?
A: Quality is built into every step. Velo Circuits holds ISO 9001 and IATF 16949 certifications. Our inspection chain includes AOI, SPI, X-ray, flying probe, ICT, and functional testing — plus in-line conformal coating for harsh-environment protection. This guarantees that both bare PCBs and assembled boards meet IPC Class 2/3 standards.
Q: What is your typical lead time, and do you offer expedited manufacturing?
A: Our standard lead time averages 15 days depending on complexity and volume, and we offer expedited options for both PCB fabrication and PCB assembly. Thanks to integrated in-house manufacturing, we control the schedule more tightly than brokers — often cutting days off the total turnaround.
Q: Why choose Velo Circuits as your PCB manufacturing and assembly partner?
A: We combine decades of engineering experience, a fully integrated fab-to-assembly workflow, and ISO/IATF-certified quality systems. Customers in over 60+ countries rely on us for consistent results — whether they need a single prototype or recurring production batches. Plus, you work directly with our team, which gives you clearer communication and better cost control.
