Conventional Single-sided PCB is the simplest type of printed circuit board, consisting of a single layer of conductive material, typically copper, applied to one side of an insulating substrate. This layout allows electronic components to be mounted and connected on one side using conductive paths, or traces. Ideal for low-density designs, single-sided PCBs are cost-effective and widely used in basic electronics, including consumer gadgets and power supplies, due to their simplicity and ease of manufacturing.

Manufacturing Processes

Given the emphasis on cost and low complexity, single-sided boards are generally produced in highly automated, conveyorized print-and-etch lines, using the following basic process flow.

  • 1
    Engineering: DFM check, EQ confirmation, MI perparation.

  • 2
    Laminate cutting: cut substrate into appropriate panel size.

  • 3
    Loading: place panels in loader which feeds them into the production line.

  • 4
    Panel cleaning, remove contaminants such as dust, grease, and residual.

  • 5
    Printing Ultra violet curable etch-resist ink then cure.

  • 6
    Exposed copper etching.

  • 7
    Striping: strip the resist.

  • 8
    Applying solder mask.

  • 9
    Legend printing.

  • 10
    Holes: Drilling for glass-based substrate or punching for paper-based substrate.

  • 11
    E-testing: test for shorts and opens.

  • 12
    FQC & FQA, follow IPC standard to check and assure the quality of the board.

  • 13
    Packing & Shipping.

Process Variations

In some variations, the conductor surface of the PWB gets insulated, exposing only pads, and then conductive paste is screened to form additional conductors on the same side of the board, thus forming double conductive layers on a single side. Most metal-core PWB consumer applications are made of aluminum substrate, which comes as a copper-clad material. PWBs made of such material do not have through-holes, and components are usually surface-mount types. These circuits are frequently formed into three-dimensional shapes.

Frequently Asked Questions

We have FR-1, CEM-1, CEM-3 and FR-4, also Aluminum and copper-based substrate. Will always follow your requirement to do.

Limited Design Complexity: Only suitable for simple circuits with low component density;
Space Constraints: Limited space for routing connections and placing components;
Performance: Not suitable for high-speed or high-frequency applications due to potential interference and signal integrity issues.

We prefer Gerber RS-274x, however other formats like ODB++(.tgz), Altium Designer(.PcbDoc), Eagle(.brd) also accepted. 

The turnaround time varies depending on the complexity and quantity of the order but typically ranges from 5 working days to a couple of weeks.

Cost-Effective: Cheaper to manufacture compared to double-sided or multilayer PCBs; Simplicity: Easier to design and produce, making them suitable for simple and low-density circuits; Repairability: Easier to repair and troubleshoot due to the single layer of circuitry.

Eagle, Altium Designer, KiCad, EasyEDA, OrCAD.

Yes, but the design must consider the current-carrying capacity of the traces and ensure adequate heat dissipation. Thicker copper layers and wider traces are often used for high-current applications.

We run visual Inspection, electrical testing and thermal testing for every board before ship, even single-sided PCB, NOT because they are simple but NOTinspection.
