PCB Manufacturing: From Design to Production

The unsung hero of electronics is the Printed Circuit Boards (PCBs), without which our devices would not function. Being an integral part of most digital devices, PCBs form the crucial building blocks of today’s technology-laden society, from the mobile devices in our pockets to communication satellites orbiting our planet. In this blog post, I will explore the detailed process of producing PCBs, from designing to manufacturing them. Understanding PCBs So, before going deeper into the manufacturing process, let’s explain what a PCB is. A printed circuit board is an interconnecting device with electronic components joined by conductive paths, pads, and features. These components are produced by etching the insulated copper from sheets laminated on an insulating base. PCBs can be single-sided (One Copper Layer), double-sided (Two Copper Layers), or multi-layered. The PCB Manufacturing Process A complex series of actions must transform a circuit idea into a completed PCB. Let's take a closer look at each of these. 1. Design and Layout The most significant element of the creation of the PCB is the creation of the design. A chip engineer employs linear circuits Electronic Design Automation (EDA) software to develop a schematic view of the circuit. This is then translated to a printed circuit board layout where one defines the placement of the components and the interconnection paths. Key considerations during the design phase include: Circuit functionality Component placement Signal integrity Power distribution Thermal management Manufacturing constraints When the design is finished, it is exported as a collection of Gerber files, complete with all the data required for production. 2. Material Selection Different materials used in the PCB production process determine its performance, lifespan, and cost. The primary material most often used is FR-4, an epoxy resin glass fiber reinforced laminate. Other materials such as polyimide, aluminum, and ceramics are also used for specific purposes. Various factors impact the choice of material, such as: Operating temperature range Dielectric constant Thermal conductivity Coefficient of thermal expansion Cost 3. Inner Layer Processing In the case of multi-layer PCB, the procedure starts from the internal layers of the respective PCB boards. The process typically involves these steps: The process typically involves these steps: - Cleaning: The copper-clad laminate is first rinsed to wash away any contaminants from the surface. - Photoresist Application: Coating of photoresist onto the copper layer This is a layer of photoresist applied onto the copper surface used in the etching process. - Image Transfer: Typically, the circuit is formed when UV light transfers the circuit pattern onto the photoresist. - Developing: This exposed and processed photoresist makes the circuit pattern whereby the unexposed portion of the photoresist is washed away. - Etching: The rest of the copper is stripped off, thus exposing only the required copper traces. - Stripping: They come through the top layer of resist, wash off the rest of the photoresist, and we can see the copper circuit pattern. - Optical Inspection: Various inspections are done on the layers, including checking for defects. 4. Layer Alignment and Bonding The separate layers of a multi-layer PCB must be aligned and glued together: - Layer Up: The inner layers are placed with layers of prepreg placed between them; this material is a material that has been soaked in epoxy resin. - Registration: They are accurately located in relation to each other through the use of the tooling holes. - Bonding: In a lamination press, high pressure and temperature are applied, thus making the prepreg flow and laminating the stack. 5. Drilling The PCB has various holes drilled for the component leads, which connect the different layers. This is usually achieved by using computerized drilling equipment for accuracy in terms of positions to be drilled. The types of holes include: Through-holes: Continue through all the layers Blind vias: Attach an outer shell to an inner compartment Buried vias: I: Integrate inner layers without going through the skin 6. Plating and Coating The board goes through multiple plating and coating procedures after drilling. - Desmear: This one clears any melted resin from the drilling process. - Electroless Copper Deposition: A thin layer of copper is then dissolved by an electrolytic process on various parts of the board, even the holes. - Copper Electroplating: A further increment of thickness is done by electroplating in copper. - Tin Plating: This includes applying a thin layer of tin to cover the layer of copper so that it may be protected from etching. 7. Outer Layer Imaging As with the outer layers, the photoresist is applied to the outer layers and then exposed and developed the same way that the inner layers are to form the circuit pattern through etching. 8. Solder Mask Application Finally, a solder mask is provided to the board; this makes the PCB look green (but can also come in other colors). This layer:  It avoids the formation of solder bridges between tiny and adjacent solder pads  Acts as a shield to the copper traces against corrosion  Provides electrical insulation 9. Surface Finish Several surface finishes can be applied on exposed copper pads and traces to avoid oxidation and improve solderability. Common finishes include:  Hot Air Solder Levelling (HASL)  Electroless Nickel Immersion Gold  Immersion Tin  Immersion Silver  Organic Solderability Preservative (OSP) 10. Silkscreen All texts, signs, and symbols are applied with the help of silkscreen printing. This includes information on rightful designators of one or several components, distinctive threats or precautions, and the logos of their manufacturers. 11. Electrical Testing Before the PCBs are shipped, they are subjected to an electrical test to check whether they have short circuits or open circuits. Flying Probe Test: Uses Moving probes to check connections. Bed of Nails Test: Goes to the test specification point and employs a fixture with spring-loaded pins that touch the test points. 12. Cutting and Profiling In this case, it would be separated here if it had to produce one or more PCBs on a panel.  One way to accomplish this is by: V-scoring and breaking Routing Laser cutting 13. Final Inspection and Packaging The manufactured PCBs are visually and optically inspected and tested using automated optical inspection.
