If this is your initial PCB production project, even a slight error can lead to significant waste of time and resources during the manufacturing process. To help ensure your first PCB production goes smoothly, here are nine key considerations.
Size profile/design ratio
To ensure your initial printed circuit board production is successful, you must pay attention to the size profile or design proportions. Excellent dimensional outlines or design ratios will enable you to produce printed circuit boards that meet market needs.
How small or large do you want your printed circuit board to be? Is there a specific location for the audio jack? Before starting initial printed circuit board production, consider common design-scale characteristics, including wiring aspects like vias, traces, and connectors, as well as the physical layout of all components on the board.

1. Similarly, depending on what you are going to build, you need to consider various form factors, such as rigid-flexible combinations, multilayer flexible, or organic electronic products. There are numerous software tools to assist you with the initial printed circuit board design. The first impression is always the most lasting. Therefore, to ensure that your initial PCB production project proceeds smoothly, you need to focus on the design scale. If the size outline or design ratio is not optimal, you might end up producing a batch of printed circuit boards that fail to meet customer expectations on their first use.
2. Mounting holes
All printed circuit boards have plated through holes for connecting opposite sides of the inner layers. Mounting holes enable the designer to attach the PCB to a surface or housing.
3. At first glance, mounting holes might seem straightforward, such as selecting a screw size that matches the circuit board or the mounting surface and then proceeding with drilling. However, this is often not the case. Ensure that everything is correct during the initial PCB manufacturing process. It is crucial to gather accurate information about the mounting holes.
4. When it comes to mounting holes, consider the mounting hardware you plan to use and the PCB aspect ratio. For instance, a larger aspect ratio can make electroplating more challenging. Using substandard software can result in inefficient circuit boards unsuitable for service.
5. Check all parts
For novices in PCB manufacturing, outsourcing parts or components is common. Most beginners start on a small scale, making it challenging to manufacture all the required components in-house. Hence, outsourcing PCB components is often the best option.
6. Unfortunately, many first-time PCB manufacturers overlook the importance of thoroughly checking that all parts are present. Neglecting this can negatively impact the initial PCB production project. Missing parts can lead to production delays and prevent you from meeting deadlines.
7. Component labels
Proper labeling of components offers numerous benefits, particularly in manufacturing. Accurate inventory and quick transactions are facilitated by professional-grade component labels.
8. The same applies to PCB manufacturing. To stay ahead of the competition, ensure that all PCB components are labeled correctly. Accurate labeling, especially for your first PCB production, helps ensure faster and more accurate manufacturing.
9. Identifying errors quickly allows for prompt changes and enhances supply chain efficiency. If you outsource parts, ensure they are labeled correctly, as not all suppliers use the same labeling standards.
10. Talk to your PCB manufacturer and assembler first, not last
When planning your PCB design, you might have consulted various resources. We recommend discussing your design with the PCB manufacturer early on. Additionally, do not forget to involve your assembler as a resource, as they can offer valuable insights throughout the manufacturing process.
11. How, you may ask? By consulting your assembler first, you gain advice on effective PCB design, industry trends, and product technologies relevant to assembling and manufacturing PCBs.
12. Best to create and manage your PCB manufacturing and BOM files
Whether producing rockets or toys, creating and managing a bill of materials (BOM) helps you accurately track and manage resources, preventing waste and unnecessary costs.
13. The BOM provides accurate information, which is crucial for making cost-effective production decisions. This principle also applies to your first PCB production project. To minimize waste, creating a detailed BOM and managing BOM files effectively is advisable.
14. Safely test your PCB prototype before assembly
A prototype is an early sample used to test the behavior of the final design. If you want to avoid losses and costly errors in the final product, especially as a first-time PCB manufacturer, thorough PCB prototype testing is essential.
15. The prototype can be a bare PCB or include PCBA, depending on your requirements. Choose a PCB factory that performs prototype testing. Understanding that the final circuit board’s quality will determine your reputation as a reliable manufacturer is crucial. Skipping prototype testing can lead to recalls and product failures, costing significant time. Make prototype testing a top priority before proceeding with full-scale PCB production.
16. Consider possible risks and how to respond or control them
Risk assessment is vital for companies aiming to remain relevant. Identifying hazards helps avoid costly mistakes, both in the workplace and in PCB manufacturing.
17. To ensure accuracy from the start, consider potential risks and develop strategies to manage them. Risks in PCB manufacturing include warpage, short circuits, cracking, contamination, and delamination, among others. Proper risk management will help you achieve profitability and successful initial production.
18. How your CM (contract manufacturer) can help
Contract manufacturing helps customers offload demanding projects to an independent party, saving both time and money.
19. In PCB manufacturing, first-time producers can save significant time and costs by engaging a contract manufacturer. Contract manufacturers are especially useful when handling complex tasks or manufacturing specific components.
