What is a PCB Assembly?

A PCB assembly (Printed Circuit Board Assembly) is the process of soldering electronic components onto a manufactured printed circuit board (PCB) to form a working unit. This includes mounting resistors, capacitors, ICs, and connectors to enable functionality. At SVTronics, we offer both PCB manufacturing services and full assembly to support your entire build.

From Prototype to Market Readiness - Our Process

We simplify the printed circuit board assembly process with a clear, quality-driven production workflow:

STEP

Once your project is reviewed, we begin sourcing components and PCB fabrication.

STEP

Our team develops routing steps and plans each production stage to align with your assembly requirements.

STEP

We begin circuit board assembly, performing rigorous inspections throughout and after production.

STEP

Final assemblies are carefully packaged and shipped directly to your facility.

Custom PCB Frequently Asked Questions

Custom PCB manufacturing is the process of designing and producing printed circuit boards built to your exact specifications. This includes custom board layouts, layer counts, materials, finishes, tolerances, and performance requirements based on your application, industry standards, and production volume.

We support a wide range of custom PCB solutions, including:

  • Single-sided and double-sided PCBs

  • Multilayer PCBs

  • High-density interconnect (HDI) boards

  • Rigid, flexible, and rigid-flex PCBs

  • High-frequency and RF PCBs

  • Heavy copper PCBs

  • Prototype through high-volume production

Each board is engineered to meet your electrical, mechanical, and environmental requirements.

Yes. We provide custom PCB prototyping to validate your design before scaling into production. Rapid prototyping helps identify potential design issues early, reduce risk, and ensure your PCB performs as expected in real-world conditions.

To begin manufacturing, we typically require:

  • Gerber files, with fab notes

  • Bill of Materials (BOM)

  • ASCII Cad Data for Pick-and-place Programming 

  • Fabrication drawings

  • Stack-up specifications

  • Assembly Drawings

  • Test Procedure 

Our engineering team reviews all documentation and provides DFM (Design for Manufacturability) feedback to optimize performance and cost.

Yes. We support:

  • Low-volume / NPI

  • Pilot runs/ FAI

  • Mid-volume builds

  • High-volume PCB manufacturing

Our scalable processes allow you to move seamlessly from prototype to full production without changing manufacturing partners.

We manufacture custom PCBs for industries including:

We understand the regulatory, quality, and performance requirements specific to each industry.

Quality is ensured through:

  • Automated Optical Inspection (AOI)

  • X-ray inspection

  • Electrical testing (flying probe or bed-of-nails)

  • Functional testing (if required)

  • IPC standards compliance

  • Traceability and documentation

Every custom PCB build follows strict quality control protocols to meet your specifications.

Yes. Our engineering team provides Design for Manufacturability (DFM) and Design for Assembly (DFA) support. We review trace widths, spacing, stack-ups, via structures, materials, and component placement to improve reliability, reduce cost, and prevent production delays.

We offer a variety of materials and surface finishes, including:

  • FR-4

  • High-Tg materials

  • Rogers and high-frequency laminates

  • Aluminum-backed PCBs

  • ENIG, HASL, Immersion Silver, OSP, and more

Material selection depends on thermal, electrical, and environmental performance requirements.

Lead times vary depending on complexity, layer count, material availability, and volume. Prototype runs may be completed in days, while larger production orders follow scheduled manufacturing timelines. We provide clear timelines during the quoting process.

Yes. We offer turnkey PCB manufacturing services that include:

  • PCB fabrication

  • Component sourcing

  • PCB assembly

  • Box Build

  • Testing and inspection

  • Packaging and logistics

This streamlined approach reduces vendor management and ensures full process control.

Our team manages component sourcing through vetted suppliers, helping mitigate shortages, long lead times, and obsolescence risks. We can also recommend alternative components when necessary to maintain production schedules.

Yes. We support builds requiring compliance with standards such as:

  • IPC

  • ISO certifications

  • ITAR (if applicable)

  • Industry-specific regulatory requirements

Documentation, traceability, and quality reporting are available upon request.

To request a quote, provide your design files, specifications, volume requirements, and timeline. Our engineering team will review your project and provide a detailed quotation with recommendations if needed.
