What Makes PCB Manufacturing So Precise? - Miracle Electronics PCB assemblies are so dense, so complicated, filled with so many tiny elements connected together, yet so precise! Have you ever wondered how something so tiny and complicated can be so precise? One of the major reasons for the precision is the latest technology used in manufacturing PCBs today. While earlier, PCB making was a manual process, over the years, the PCB manufacturing process has significantly changed, thanks to the latest technological innovations that have allowed PCB manufacturers to innovate accurately and skilfully. Here’s how a prototype PCB assembly from India is made (https://www.miracle.net.in/blog/build-pcb- prototype/) with such skill and accuracy. Pre-manufacturing – Planning Before a PCB prototype is begun for manufacturing, there is a lot of planning done, considering countless aspects. First and foremost, the PCB manufacturer will look over the design and Gerber files. Then, step-by-step instructions will be laid out for
fabrication, which will be reviewed by an engineer, who will then convert these plans into a data format that will help engineer the board. Any issues will also be checked for with formatting or cleaning up. Based on this data, the final board will be created. Manufacturing Step 1 – Plotting Once inspected and finalized, a panel array is then chosen for the best fit, after which photo plotting begins. This is the first step of the production process. A laser is used to plot the patterns, silk screens, and other primary images that are required on the PCB. Step 2 – Lamination In the case of multi-layered PCBs, the multiple layers need to be fused together, which can be attained with the help of lamination, that is done using heat and pressure. Step 3 – Drilling Once heat and pressure laminates the layers together, expert drilling systems are used, programmed to drill holes into the board, accurately and precisely. This drilling program ensures that there is no human error while manufacturing the PCB. Step 4 – Copper Deposition and Plating The copper layer of the PCB, which is deposited through electrolysis, is an important part of the PCB, the conductive property essential to the functionality of the PCB prototype. PCBs generally become conductive after electroplating, which is where the copper is plated via a plating bath. These copper tracks prove
to be conductive tracks that connect two points within the circuit board. Post-manufacturing – Testing After the prototype is built, it is thoroughly tested in every way to identify any mistakes or flaws that may lead to errors or unexpected end results. Identifying these mistakes in the prototype can help correct them right there so that the rest of the manufactured products are not flawed, thus saving on costs and time. Once the prototype is confirmed to be perfect, the remaining lot is manufactured. You can see how the latest technologies used bring such precision to PCBs. For such a precise and accurate PCB assembly from India, you can get in touch with Miracle Electronics, the leading PCB assembly manufacturer in the country, who is an expert in building PCBs of all kinds and sizes in world-class manufacturing environments to provide scalable, high-quality, and low-cost PCB assemblies to totally satisfy customers!
