High Volume PCB Assembly

Printed Circuit Board (PCB) assembly plays a vital role in modern electronics manufacturing. Different businesses have different production needs some require small prototype runs, while others depend on consistent, large-scale production to meet market demand. For companies that need dependable output at scale, high volume PCB assembly becomes a critical part of their supply chain.

At Sierra Assembly Technology, Inc., we provide US-based PCB assembly services designed to support both growing and established manufacturers. Our focus is on quality, repeatability, and efficiency, helping customers across multiple industries achieve dependable production without unnecessary complexity.

What High Volume PCB Assembly Means for Your Business

High volume PCB assembly involves producing large quantities of assembled circuit boards while maintaining consistent quality, performance, and compliance. This type of manufacturing requires advanced automation, experienced technicians, and a disciplined quality system.

By investing in modern equipment and skilled professionals, Sierra Assembly ensures that every printed circuit board assembly meets design requirements, industry standards, and customer expectations whether the order is in the thousands or beyond.

High Volume PCB Assembly Capabilities

Our facility is equipped to handle complex assemblies and demanding production schedules. We support a wide range of board types and component technologies, allowing customers to scale production with confidence. Core Assembly Capabilities: 

Assembly Capability	Description
Surface Mount Technology (SMT)	High-speed, high-accuracy placement for dense and complex designs
Through-Hole Assembly	Reliable mechanical strength for components requiring durability
Selective Soldering	Precision soldering for mixed-technology PCB designs
Hand & Machine Soldering	Flexibility for specialized or low-tolerance components
Solder Paste Printing	Jet and screen printing for consistent solder application

These capabilities allow us to support large volume PCB assembly while maintaining repeatable results across every production run.

Testing, Inspection, and Quality Control

Quality is not an afterthought it is built into every stage of our PCB assembly process. Each board is inspected and tested to ensure it performs exactly as intended before shipment.

Quality Process	Purpose
Automatic Optical Inspection (AOI)	Detects placement and soldering defects
X-ray Inspection	Verifies hidden solder joints and BGA connections
In-Circuit Testing (ICT)	Confirms electrical integrity
Functional Testing	Ensures real-world performance
DFM Review	Improves manufacturability before production begins

These processes help reduce defects, minimize rework, and protect product reliability in high-volume production environments.

RoHS Compliance and BOM Support

Sierra Assembly provides complete RoHS compliance support for customers who must meet environmental and regulatory requirements. Our team evaluates each bill of materials to confirm compliance and resolve any potential issues before assembly begins.
Our RoHS services include:

• Verification of component compliance
• Identification of approved alternatives when needed
• Component sourcing and procurement
• Material declarations and safety documentation

All assemblies produced at our facility are lead-free and compliant with RoHS standards.

From Prototype to Production Scale

Customers often begin with prototype builds before moving into full production. Sierra Assembly supports this entire lifecycle, allowing you to transition smoothly from early testing to high volume PCB assembly without changing manufacturing partners.

This approach improves consistency, shortens ramp-up time, and reduces risk during scale-up.
