Flexible Printed Circuit Manufacturers & Flex PCB Manufacturing Services

When your design requires a circuit that can fit into tight spaces, follow complex shapes, or support compact electronic assemblies, flexible PCB technology can provide the design flexibility you need. Sierra Assembly Technology provides flexible PCB manufacturing and assembly support for projects ranging from prototyping to production.

With 30+ years of experience, U.S.-based engineering support, and established quality systems including ISO 9001:2015 and AS9100D, we help you move flexible circuit designs from engineering requirements toward production. Sierra Assembly is also ITAR Registered for projects requiring appropriate U.S. handling and support.

Whether you need a flex PCB prototype, flexible printed circuit, multilayer flex PCB, or rigid-flex PCB, our team can review your requirements and determine the appropriate manufacturing and assembly approach.

                            

Flexible PCB Manufacturing for Your Application

Flexible printed circuits use flexible substrates, commonly polyimide-based materials, to create circuit assemblies that can bend, fold, or conform to available space. This can help you design electronics where conventional rigid boards, connectors, or wiring arrangements may create space or assembly challenges.
Our flexible PCB capabilities support different circuit configurations, including:

• Single-sided flex PCBs for simpler circuit requirements
• Double-sided flex PCBs for designs requiring routing on both sides
• Multilayer flex PCBs for more complex circuit and interconnection requirements
• Rigid-flex PCBs that combine rigid board sections with flexible circuit areas

The right construction depends on your design, electrical requirements, mechanical constraints, material selection, and production needs. Our team can review your design requirements before production to help establish the appropriate approach.

Our Flex PCB Manufacturing & Assembly Capabilities

Flex PCB Prototyping and Production Support

If you are developing a new flexible circuit, getting the design into production requires more than selecting a board material. Mechanical requirements, layer construction, component placement, assembly processes, and testing requirements all need to work together.

Our flex PCB prototyping support helps you move from an initial design toward a manufacturable solution. Once your requirements are established, we can support the transition into production based on your project volume and schedule.

For qualifying projects, 24-hour turnaround may be available after reviewing your requirements and schedule.

If you have an existing design package, contact our team to discuss the required manufacturing and assembly process.

Why Use Flexible Printed Circuits?

Flexible PCBs can be useful when your product requires a circuit that occupies less physical space or must conform to a particular mechanical configuration.
Depending on your design, flexible circuits can help you:

• Reduce the space required for electrical interconnections
• Support compact electronic assemblies
• Route circuits around or through constrained areas
• Reduce reliance on separate wiring and connectors in appropriate applications
• Integrate electrical connections into products with moving or non-planar configurations
• Combine flexible and rigid sections through rigid-flex construction

The actual benefits depend on the design and application. Our engineering team can review your requirements to determine whether flex or rigid-flex construction is appropriate for your project.

Applications for Flexible Circuit Boards

Flexible printed circuits are used in applications where space, packaging, routing, or mechanical configuration are important considerations.
Sierra Assembly supports flexible PCB requirements for applications including:

• Medical Electronics: Flexible circuits can support compact medical electronic assemblies where space and component integration are important.
• Aerospace Electronics: Flex and rigid-flex constructions can be used in aerospace electronics where compact packaging and controlled interconnections are required.
• Automotive Electronics: Flexible circuits can support sensors, control electronics, and other automotive assemblies requiring efficient electrical routing.
• Consumer Electronics: Compact electronic products can use flexible circuits to accommodate limited internal space and complex product geometries.
• Industrial Electronics: Flexible PCB solutions can be applied to industrial electronic equipment where conventional rigid-board layouts may not fit the required mechanical configuration.

Why Choose Sierra Assembly for Your Flex PCB Project?

Your flexible PCB project may involve specific design requirements, production quantities, PCB assembly needs, and delivery expectations. Sierra Assembly works with you to understand those requirements before determining the right path forward.

With 30+ years of experience, we understand that every project has different priorities. Our U.S.-based engineering support gives you a direct point of contact for discussing technical requirements, production considerations, and project schedules.

We also support projects from prototype through production, so you can work with the same team as your requirements develop. For qualifying projects, 24-hour turnaround may be available after reviewing your requirements and schedule.

If you have a flex PCB design ready for review or are still evaluating your manufacturing requirements, contact Sierra Assembly to discuss your project and request a quote.
