PCB prototyping refers to the trial production of printed circuit boards before mass production. It is mainly applied when electronic engineers have designed the circuit and completed the PCB layout, and then proceed to conduct small batch trial production with a PCB factory. Below, we will introduce the preparations needed before PCB prototyping.PCBs can be simple or complex. Simple PCBs are easy to prototype, but for complex circuit boards, caution is required. If relevant testing tools are not used during the PCB prototyping process, any issues may only be discovered after the PCB is completed, which would be too late. Therefore, it is essential to make thorough preparations before prototyping.
Preparations Needed Before PCB Prototyping1. Creation of Physical BordersA closed physical border serves as a basic platform for subsequent component layout and PCB prototyping. It is crucial to ensure precision, and it is best to use rounded corners to avoid injuries from sharp edges and to reduce stress concentration.2. Introduction of Components and Networks, and Layout of ComponentsWhen introducing components and networks into the drawn border during PCB prototyping, it is essential to operate carefully according to the guidelines, including the packaging forms of components and network issues. Following the guidelines helps to minimize problems. The layout of components and routing during PCB prototyping significantly affects the product’s lifespan, stability, and electromagnetic compatibility, which should be given special attention. Generally, the following principles should be observed: placement order and attention to heat dissipation.3. PCB Design Routing and AdjustmentsWhen designing the PCB routing, it is advisable to pay attention to the processing parameter requirements or consult a reliable PCB prototyping manufacturer to greatly reduce the defect rate. After completing the PCB design routing, adjustments should be made to the text, individual components, and routing, as well as copper plating (this task should not be done too early, as it may affect speed and complicate PCB design routing), all to facilitate production, debugging, and maintenance.4. Network Inspection and VerificationSometimes, due to operational errors or negligence, the network relationships of the drawn PCB may differ from the schematic diagram. Therefore, inspection and verification are necessary. Thus, it is recommended to perform verification after drawing before proceeding with subsequent work.The above is an introduction to what PCB prototyping is and the preparations needed before prototyping. We hope this can help everyone. For more information on PCB prototyping, please follow the updates from Lingzhu Prototyping.
