Choose Your Single-Sided PCB Construction
One patterned copper circuit layer can be built on different substrates. PCBELEC supports four manufacturing directions, helping you connect the circuit with the right rigid, metal-base or flexible construction.
Rigid Insulating Substrate
Single-Sided FR-4 PCBs
A single copper circuit layer on an FR-4 laminate. Bring together the material grade, copper, holes and finish for a custom rigid board build.
The project calls for a fixed board shape and a rigid insulating substrate, with routing on one copper circuit layer.
Aluminum-Base Construction
Single-Sided Aluminum PCBs
A single-layer circuit with an aluminum base. For conventional insulated builds, coordinate the circuit copper, dielectric and metal base with the required mounting interface.
The design calls for an aluminum-base thermal path and a defined electrical insulation and mechanical construction.
Copper-Base Construction
Single-Sided Copper-Based PCBs
A single-layer circuit built around the specified copper-base and thermal structure. Coordinate the base, insulation, thermal regions and mechanical features as one build.
A copper base or a specifically defined thermal interface is part of the design, with its electrical relationship clearly established.
Flexible Circuit Construction
Single-Sided Flexible PCBs
One copper circuit layer on a flexible base, with the specified coverlay or protection. Coordinate bend regions, connection areas and local reinforcement with the intended installation.
The circuit must accommodate installation bends, flexible connections or defined repeated-flexing requirements.
Not Sure Which Construction Fits?
Start with the requirements that matter to the project. Our team can help discuss the manufacturing options.
- Electrical: copper, connection features and required insulation.
- Thermal: the intended heat path, base construction and mounting interface.
- Mechanical: fixed shape, installation bends, repeated flexing or local support.
Single-sided describes one patterned copper circuit layer—not one universal material or manufacturing route. If the design needs routing on two copper layers, explore double-sided PCB manufacturing .

Metal-Base Builds Beyond a Standard Outline
Combine aluminum or copper bases with thermal dielectric options, circuit copper, mounting features and custom profiles. Our MCPCB service provides additional material and process references for these constructions.
Explore MCPCB Manufacturing CapabilitiesFlexible Builds with Protection & Local Support
Bring coverlay, connection openings, stiffener locations and bend requirements into the same build definition. The flex capability page provides more detailed material, dimensional and process information.
Explore Flexible PCB CapabilitiesKeep Circuit Copper and Base Thickness Separate
On metal-base boards, circuit copper weight is not the aluminum or copper-base thickness. On flexible circuits, local stiffeners add thickness only where specified. Keeping these dimensions separate helps us quote and manufacture the intended construction.

Review the laminate specification, thickness, copper, holes and finished outline together. Panel arrangement and separation requirements are part of the manufacturing proposal, not details to leave until after quoting.
Aluminum-Based
Dielectric, Metal Base & Mechanical Features
Define the dielectric and aluminum-base requirements, then include mounting holes, machining and thermal-interface details. Compare quotations against the same material and insulation specification.
Copper-Based
Thermal Construction & Base Processing
Specify the copper base, insulated or special thermal structure and critical interface features. Base machining, selective treatments and verification requirements belong in the initial inquiry.
Flexible
Flex Material, Protection & Reinforcement
Bring the flexible construction, coverlay, stiffeners and adhesive regions into the quotation scope. Include the delivery format and handling or installation requirements that affect the build.
Make the Quotations Comparable

Single-Sided PCB Manufacturing FAQ
Answers to common questions about one-layer circuit construction, material choices and preparing the right manufacturing requirements for your selected build.
Are single-sided PCB and single-layer PCB the same thing?
In this manufacturing context, both terms describe a board with one patterned copper circuit layer. The term does not specify whether the base is FR-4, aluminum, copper or flexible material.
The substrate, dielectric, mask, coverlay or stiffener does not automatically add another routed circuit layer. See the single-sided construction options for the four manufacturing directions.
Which single-sided PCB constructions can I request?
PCBELEC supports single-sided FR-4, aluminum-based, copper-based and flexible PCB inquiries. Select the construction in the RFQ and provide the material, electrical, thermal or mechanical requirements relevant to the build.
If the construction is not fixed, select “Other / Help Me Choose” and explain the requirements driving the design.
Does a metal base make an aluminum or copper-based PCB two-layer?
Not by itself. In a conventional insulated single-sided metal-base construction, the patterned copper circuit is separated from the metal base by a dielectric. The base is not a second routed copper circuit layer.
Describe the metal base, dielectric and any special thermal or electrical relationships separately in the construction drawing.
Do all copper-based PCBs use the same thermal construction?
No. A conventional insulated copper-base structure should not be treated as identical to a specified special thermal-pad construction. Define the circuit, thermal regions and electrical isolation requirements on the drawing.
Review copper-based PCB manufacturing and include the intended structure with the inquiry.
Should a single-sided flexible PCB use the same protection as an FR-4 board?
The protection should follow the flexible construction and use requirements. Specify coverlay or the intended coating, contact openings, bend regions and any local stiffeners rather than assuming a rigid-board mask specification.
See single-layer flexible PCB manufacturing for the related build details.
What material and thickness information should I provide?
For FR-4, identify the laminate grade and finished thickness. For metal-base boards, define the base, dielectric where applicable and overall thickness. For flex, define the flexible construction and any local reinforced thickness.
State copper circuit thickness separately from metal-base thickness. The construction requirements comparison summarizes the main differences.
Do all single-sided PCB holes need plating?
No. Layer count alone does not define the hole treatment. A conventional non-plated-hole single-sided board does not need through-hole copper plating for layer-to-layer connections.
Specify the required hole attributes and finished dimensions. For metal-base or special constructions, also define the required isolation from the base and any metallization requirements.
What files are needed for a single-sided PCB quote?
Send the copper artwork, applicable protection-layer and marking data, holes, finished outline and quantity. Include a construction drawing when the circuit files do not fully describe the base, dielectric, thermal regions or reinforcement.
Add material, finish, delivery-format and verification requirements. Use the PCB manufacturing file guide to prepare a consistent package.
Does one copper layer always mean the lowest-cost PCB?
No. The base material, dielectric, copper, board geometry, protection, machining, reinforcement and verification requirements all contribute to the manufacturing proposal.
Compare quotations for the same construction and acceptance requirements. Include quantity, delivery destination and the required date. See our cost and production planning section for related considerations.
Can I start with prototypes and place production orders later?
Yes. PCBELEC supports prototype and production inquiries across the single-sided constructions presented on this page. Include the intended production construction when defining an evaluation build.
For repeat orders, reference the earlier order and state whether the design is unchanged. Supply a complete revised package when materials, thermal features, reinforcement or other details change.
How should I request electrical, thermal or flex-use verification?
Define the property or performance to be demonstrated, test conditions, acceptance criteria, sampling and records. Circuit connectivity, circuit-to-base insulation, thermal performance and repeated bending are different verification topics.
Material data and fabrication inspection should not be assumed to replace application-level validation. Review the manufacturing and verification section and include the required scope with the inquiry.
Is single-sided PCB manufacturing the same as single-sided assembly?
No. Single-sided PCB manufacturing describes a bare board with one copper circuit layer. Single-sided assembly describes component placement on one side and does not, by itself, define the circuit-layer count.
This PCBELEC service covers bare-board fabrication. For component sourcing and PCB assembly, continue to JHYPCB's PCB assembly services.
