With state-of-the-art facilities and a team of experienced professionals, PCB-UK offers a wide range of PCB solutions for various industries, including automotive, aerospace, medical, and consumer electronics.

What is a PCB?

A printed circuit board (PCB) is a fundamental component in modern electronics. It is a flat board made of insulating materials, such as fiberglass or composite epoxy, with conductive copper traces etched onto its surface. These traces connect various electronic components, such as resistors, capacitors, and integrated circuits, to form a complete electronic circuit.

PCBs come in different types, depending on the number of layers and the complexity of the circuit design:

PCB Type	Description
Single-sided	Conductive traces on one side of the board
Double-sided	Conductive traces on both sides of the board
Multi-layer	Multiple layers of conductive traces separated by insulating layers
Flexible	Made of flexible materials for applications requiring bending or folding
Rigid-flex	Combination of rigid and flexible sections for complex designs

PCB-UK’s Manufacturing Process

Design and Prototyping

The PCB manufacturing process at PCB-UK begins with the design and prototyping stage. Customers can submit their PCB designs in various file formats, such as Gerber, ODB++, or IPC-2581. PCB-UK’s experienced design team reviews the files for manufacturability and provides feedback or suggestions for improvement.

For customers who require assistance with PCB design, PCB-UK offers design services using industry-standard EDA (Electronic Design Automation) tools, such as Altium Designer, Cadence OrCAD, and Mentor Graphics PADS.

PCB Fabrication

Once the design is finalized, PCB-UK proceeds with the fabrication process. The key steps in PCB fabrication include:

1. Copper Clad Laminate Preparation: The process begins with the selection of the appropriate copper clad laminate (CCL) based on the PCB design requirements. The CCL is cut to size and cleaned to remove any contaminants.

2. Drilling: Holes are drilled into the CCL for through-hole components and vias using high-speed CNC drilling machines.

3. Patterning: The copper traces are patterned onto the CCL using a photolithography process. This involves applying a light-sensitive resist, exposing it to UV light through a photomask, and developing the resist to reveal the desired copper pattern.

4. Etching: The exposed copper is etched away using a chemical solution, leaving only the desired copper traces on the board.

5. Lamination (for multi-layer PCBs): For multi-layer PCBs, the individual layers are aligned and laminated together under high pressure and temperature to form a single board.

6. Surface Finish: A surface finish, such as HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), or OSP (Organic Solderability Preservative), is applied to protect the copper traces and improve solderability.

7. Solder Mask and Silkscreen: A solder mask is applied to the PCB to protect the copper traces from oxidation and prevent solder bridges during assembly. A silkscreen layer is added to provide component labels and other markings.

8. Electrical Testing: The fabricated PCBs undergo electrical testing to ensure they meet the design specifications and are free of short circuits or open connections.

PCB Assembly

PCB-UK offers both PCB fabrication and assembly services. The PCB assembly process involves the following steps:

1. Solder Paste Application: Solder paste is applied to the PCB pads using a stencil or screen printing process.

2. Component Placement: Surface mount (SMT) and through-hole (THT) components are placed onto the PCB using automated pick-and-place machines or manual assembly.

3. Reflow Soldering: The PCB with the placed components is passed through a reflow oven, where the solder paste melts and forms a permanent electrical and mechanical connection between the components and the PCB.

4. Wave Soldering (for THT components): If the PCB contains through-hole components, it undergoes a wave soldering process, where the board is passed over a molten solder wave to solder the component leads to the PCB.

5. Inspection and Testing: The assembled PCBs are visually inspected and undergo functional testing to ensure they meet the required specifications and performance criteria.
