5 Key PCB Layout Considerations for Efficient Circuit Board Assembly and Soldering Production Processes
When designing a PCB layout, various questions inevitably arise. Is this PCB best suited for a single-layer, double-layer, or multi-layer configuration? How should you protect against ESD/EMI? Will the printed circuit board assembly (PCBA) use a single-sided or double-sided process? … Continue reading

Exploring EVT/DVT/PVT: Explaining the Three Crucial Validation Stages in New Product Development
When developing a new product, it is common to conduct a “trial run” to obtain a prototype sample. This serves two purposes: firstly, it allows developers to further test and validate the prototype’s functionality, and secondly, it helps the manufacturing … Continue reading
