What is a Single-Sided PCB?
A single-sided PCB is a type of PCB built with one layer of conductive copper laminated onto a substrate material. First introduced commercially in the 1950s, single-sided PCBs simplified early electronics manufacturing by allowing all conductive paths to be placed on one surface. This single layer PCB structure allows for simplified routing, reduced manufacturing cost, and mechanical rigidity suited for various applications.
The production process for a single sided printed circuit board involves applying a thin copper sheet to a dielectric substrate, patterning the circuit layout through a photo-imageable process, and applying a protective solder mask to shield exposed traces.
The copper layer is laminated using heat and adhesive systems to achieve strong adhesion between the substrate and the conductive material. As a basic type of PCB, single-sided designs eliminate the need for via interconnections, reducing manufacturing complexity and improving yield for high-volume production.
Single-sided boards are manufactured with copper weights ranging from 0.5 to 3 oz per square foot, depending on current carrying and mechanical strength requirements. Material selection, including FR4, High TG FR4, or CEM-3, impacts thermal resistance, dielectric strength, and board rigidity based on the operating environment.
Having only one conductive layer minimizes signal integrity challenges such as crosstalk and interlayer noise, although heat dissipation and limited routing density must be carefully considered in the PCB design phase.
PCB Manufacturing Process
Where are Single-Sided PCBs Used?
Single-sided PCBs are widely used in industries where circuit simplicity, cost control, and mechanical durability are more important than multilayer complexity. Single sided PCB assembly manufacturers provide printed circuit boards for:
In consumer electronics, single-sided PCBs are used in calculators, audio amplifiers, remote controls, and small appliance circuits. These PCB boards require minimal routing complexity and benefit from the mechanical stability and low production cost of a single layer solution.
Standard FR4 substrates combined with automated wave soldering processes make high-volume production fast and reliable for everyday electronics.
Industrial systems use single sided circuit boards in control panels, sensor modules, motor drives, and measurement devices. The conductive copper traces support moderate current loads and resist mechanical shock, making this type of PCB ideal for robust operating environments.
In applications exposed to higher temperatures, High TG FR4 or CEM-3 materials provide better thermal resistance and longer service life under load.
Automotive applications integrate single sided PCBs into lighting systems, dashboard controls, mirror adjusters, and actuator controllers. The PCB must withstand vibration, thermal cycling, and moisture exposure while maintaining reliable circuit performance with one layer of conductive copper.
FR4 materials with optional ROHS-compliant solder finishes meet automotive reliability and environmental standards.
LED lighting modules and compact power supply units rely on single-sided printed circuit boards to handle current distribution, voltage regulation, and thermal dissipation. A high copper thickness and precision solder mask finish ensure electrical integrity and consistent performance in enclosed or high-heat installations.
For high-frequency LED drivers and converters, optional Rogers substrates support lower dielectric loss and improved thermal transfer properties.
Features of Our Single-Sided PCBs
We manufacture single-sided PCBs using high-resolution imaging and chemical etching processes to achieve trace widths and spacing down to 4 mils. The circuit layout accuracy supports optimized signal flow, minimal resistance paths, and uniform current distribution across the PCB board.
Fine feature patterning is verified under IPC-A-600 and IPC-6012 criteria to ensure that single-sided printed circuit boards meet mechanical and electrical tolerance requirements critical for assembly and performance, supporting higher circuit reliability and reducing signal integrity issues under load.
Our fabrication process includes the application of protective solder masks with thicknesses between 15 and 25 microns, depending on board type and environment. Optional surface finishes such as HASL, ENIG, or OSP are applied to protect exposed pads and enhance solderability.
The solder mask shields copper circuits from oxidation, mechanical abrasion, and solder bridging during reflow or wave assembly. Surface finish choice is tailored based on product shelf life, soldering method, and environmental exposure conditions.
We select PCB materials such as standard FR4, High TG FR4, CEM-3, and Rogers (preferred for RF applications, they’re also used in LED and high-thermal-load designs) halogen-free laminates depending on thermal, mechanical, and dielectric requirements.
Our team evaluates each substrate for glass transition temperature (Tg, the temperature where the material transitions from rigid to soft), coefficient of thermal expansion (CTE, the rate at which the material expands when heated), dielectric constant (a measure of a material’s ability to store electrical energy), and insulation resistance (the ability of the material to resist electrical leakage under voltage stress).
Our process allows for copper thickness from 0.5 oz to 3 oz, depending on current load and mechanical strength needs. Trace width and spacing are calculated based on amperage flow, thermal rise limits, and allowable voltage drop, ensuring durable conductive pathways across the PCB.
In-process inspections include copper peel strength testing to validate the adhesion between the copper layer and the dielectric base, delivering quality single sided printed circuit structures ready for production deployment.
What Makes Copper Core PCBs Different From Standard Circuit Boards?
Copper core PCBs differ from standard circuit boards through their specialized multi-layer structure designed for superior thermal performance. The foundation of every metal core printed circuit board is a solid copper plate that efficiently conducts heat away from critical board components. This metal substrate is covered with a high-performance insulated metal layer that provides electrical isolation while still allowing heat transfer. Copper PCBs are then topped with copper foil where components are mounted.
Our Single-Sided PCB Testing Process
We inspect each printed circuit board visually at multiple stages to identify etching defects, open circuits, solder mask misalignments, pad contamination, or mechanical damage.
Optical magnification and automated optical inspection (AOI) systems verify fine conductor spacing and pad placement across the entire PCB board surface, minimizing the risk of electrical shorts, open circuits, and misaligned assembly points during downstream PCB assembly.
Bare board testing (BBT) procedures are applied after visual inspection to confirm that the board is electrically sound before component assembly.
Our technicians evaluate solder mask application thickness, coverage uniformity, and adhesion strength, typically achieving between 15 and 25 microns in cured thickness. The soldering process quality is enhanced by verifying that mask windows align precisely with pad locations, preventing solder bridging during reflow or wave soldering.
Silkscreen markings are reviewed for legibility, chemical durability, and positional tolerance under IPC-A-610 guidelines.
All single-sided printed circuit boards undergo 100% electrical continuity testing using flying probe testers or custom-built fixture systems. Open circuits, shorts, and cross-connections are detected and recorded.
Electrical verification follows IPC-9252 standards for bare board electrical testing, confirming that each circuit meets the resistance, open, and short specifications defined in the project documentation.
We perform insulation resistance testing between isolated conductive layers and traces where required, applying controlled high-voltage conditions to detect micro shorts or dielectric failures.
Test voltages and insulation thresholds are set based on IPC-9252 recommendations and customer specifications. This ensures that the substrate material and circuit isolation properties meet critical product safety and performance standards.
Finished boards are measured for length, width, thickness, hole positioning, and mechanical tolerances according to IPC-2221 requirements. Cross-sectional samples verify copper thickness, distribution uniformity, and the presence of any plating voids.
Copper peel strength testing is performed on representative samples, requiring a minimum adhesion of 5 lbs/inch to ensure strong bonding between the copper layer and the underlying dielectric substrate.
Depending on the application, we perform environmental stress tests such as thermal cycling, humidity resistance, and solder shock to validate field performance. Thermal cycling subjects boards to repeated heating and cooling between -40 °C and +125 °C to simulate real-world operating stresses and uncover latent defects such as microcracking or delamination.
Humidity resistance testing exposes completed boards to elevated humidity (up to 85% RH at 85 °C) to verify insulation resistance stability and detect moisture ingress pathways. Solder shock testing rapidly immerses boards in molten solder baths to evaluate pad adhesion, copper layer integrity, and substrate dimensional stability under sudden thermal loads.
