What is PCB Manufacturing?
PCB manufacturing is the process of creating printed circuit boards that mechanically support and electrically connect electronic components using conductive tracks, pads, and other features etched from copper sheets laminated onto a non-conductive substrate. The manufacturing process involves multiple stages, each critical to ensuring the final product’s quality, functionality, and reliability.
The first step in PCB manufacturing is the design phase, where engineers create the PCB layout using specialized software like Eagle, Altium, or KiCad. This design includes the placement of components, routing of electrical connections, and the creation of vias, pads, and traces. The final design is then exported as Gerber files, which contain all the necessary information for manufacturing the PCB.
Material Preparation
PCBs are typically made from a substrate material like FR4 (a composite of woven fibreglass cloth with an epoxy resin binder) with a thin layer of copper foil on one or both sides. The copper-clad laminate is cut into the required sizes, preparing it for the subsequent steps. The choice of substrate material depends on the application, with some PCBs using high-frequency laminates or flexible substrates for specific uses.
Photoresist Application
In this stage, a photoresist layer, which is sensitive to ultraviolet (UV) light, is applied to the copper-clad board. This can be done using a liquid photoresist or a dry film photoresist, depending on the manufacturing process. The photoresist acts as a protective layer that helps in defining the circuit pattern during the exposure process.
Exposure and Development
The PCB is then exposed to UV light through a photomask that contains the circuit pattern. The UV light hardens the photoresist in the areas that are exposed, while the unexposed areas remain soft. After exposure, the board undergoes a development process where the soft photoresist is washed away, revealing the underlying copper that needs to be etched away.
Etching
The etching process removes the unprotected copper from the PCB, leaving behind only the copper traces that form the circuit. The most common method for etching is using a chemical solution, such as ferric chloride or ammonium persulfate. This step is crucial for ensuring the accuracy and functionality of the PCB’s circuit design.
Drilling
Drilling is performed to create the necessary holes for mounting components and for vias, which allow connections between different layers of the PCB. The holes are typically drilled using CNC machines that offer high precision and can drill thousands of holes in a single board. The diameter and placement of these holes must be exact to ensure proper component alignment and functionality.
Plating
After drilling, the next step is plating the holes with copper to create electrical connections between the different layers of the PCB. This process, known as through-hole plating, involves depositing a thin layer of copper inside the drilled holes, ensuring reliable conductivity across the board. The board may undergo multiple plating processes depending on the design and complexity of the PCB.
Solder Mask Application
A solder mask, usually green, is applied to the surface of the PCB to protect the copper traces from oxidation and to prevent solder bridges from forming during component assembly. The solder mask covers everything except for the pads where components will be soldered. This step is essential for ensuring the long-term reliability and durability of the PCB.
Silkscreen Printing
The silkscreen layer is applied next, which adds labels, logos, and other markings to the PCB. These markings help in identifying components and understanding the board’s layout during assembly and testing. The silkscreen is typically applied using a screen printing process, although some manufacturers use digital printing for finer details and higher resolution.
Surface Finishing
Surface finishing is applied to the exposed copper pads to protect them from oxidation and ensure good solderability. Common finishes include HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), and OSP (Organic Solderability Preservative). The choice of finish depends on the PCB’s intended use, budget, and environmental considerations.
Testing and Quality Control
After all the manufacturing steps are completed, the PCB undergoes rigorous testing to ensure it meets design specifications and functions correctly. Common testing methods include Automated Optical Inspection (AOI), Electrical Testing (ET), and X-ray inspection for multilayer boards. This step is crucial for identifying defects and ensuring that only high-quality boards proceed to the assembly phase.
Assembly
PCB assembly involves placing and soldering components onto the board. This can be done using Surface Mount Technology (SMT) or Through-Hole Technology (THT), depending on the design. Automated pick-and-place machines position components accurately, while reflow soldering or wave soldering techniques are used to secure the components to the board. Once assembled, the PCBs undergo further testing to ensure that all components are functioning as intended.
