Share methods to avoid common PCB design errors
When you rely on printed circuit boards to achieve the expected functionality of the product, any small mistake can cause a huge setback to your operation. This is why it is so important to handle all content correctly in the first place. Of course, this is not always possible - but if you plan ahead and carefully avoid these misfortunes, you will be more likely to be 100% satisfied with the final result.
Avoiding common PCB errors
The design is too complex: The PCB manufacturing process is already very complex. Ideally, your PCB assembly plant would want to manufacture and manufacture printed circuit boards in a cost-effective manner. An overly complex design can make this process more complex, which may actually put the functionality of the circuit board at risk. Collaborate with your PCB assembler to ensure that circuit boards are constructed in a simple and efficient manner, avoiding unnecessary delays and reducing costs.
Incorrect or missing Gerber sent: Gerber files must be industry standard RS274X. All current versions of CAD programs can generate - X format. Gerber files are used to paste layers.
Unable to quickly detect errors: Your PCB wafer manufacturer and assembly partners should be able to detect most errors before PCB production, provided they have a comprehensive design review process. They should also use advanced technology to conduct a complete PCB inspection to ensure that your circuit board can function properly after delivery. Otherwise, your operations may suffer significant losses due to delays or even product failures. Before choosing a PCB manufacturer, please ensure that they have the ability to fulfill their PCB inspection commitments.
Incorrect BOM format: The component BOM must be in CSV format. PDF documents cannot be reliably converted to CSV format. In addition, the BOM needs to include reference marks, values, packaging/labels, descriptions, and part numbers.
Not collaborating with reputable PCB assembly factories: Some companies believe they can manufacture their own PCBs or want to collaborate with the cheapest PCB manufacturers they can find. Unfortunately, this often leads to delays and costly errors - so in the long run, you won't save much! Please remember that compared to 50 manual welding operators, automated production lines can also place and weld more components. This means that when time is a factor (almost always), you will choose a company that can quickly produce PCBs. Usually, this means that you will collaborate with companies with high reputation and extensive experience in the industry, rather than just selecting based on price.
Missing file: The SMT machine uses XYRS coordinates for SMT parts. Almost every CAD program can generate XYRS data. If you do not use turnkey service, each kit must also include a packing list or invoice for comparison with the BOM. In addition, the packaging box should indicate the internal operation number.
