In microcontroller development, we often need to hand over the designed PCB files to the factory for production. Recently, one of our engineers encountered a troubling issue, as the PCB board lacked Mark points, resulting in deductions from the SMT factory. Today, we will discuss this topic: how important are Mark points in SMT processing? … Read more
PCB Panel Design: The Perfect Balance of Cost and Efficiency In PCB manufacturing, panel design directly affects production efficiency and cost. A reasonable panel scheme can increase SMT placement efficiency several times, while incorrect designs can lead to reduced processing speed or even production failure. This article will delve into the core points of PCB … Read more

[Disassembly] Monument This is a low-power Bluetooth device, and this tiny circuit board integrates six types of sensors. Let’s see what it can transmit. ▽ It is called “Monument” because it looks like a stone tablet. ▽ Stripped of its fancy attire, revealing the transparent “xq underwear”. ▽ Shyly turning away. ▽ Screwless design for … Read more
Part One: Design Guidelines for Mixed-Signal Circuit Boards The operation of analog circuits relies on continuously varying currents and voltages. Digital circuits operate by detecting high or low levels at the receiving end based on predefined voltage levels or thresholds, which corresponds to determining the logical states of “true” or “false”. Between the high and … Read more
Printed Circuit Board Comprehensive Design The comprehensive design of a Printed Circuit Board (PCB) is a complex process that involves multiple fields such as electronic engineering, materials science, thermodynamics, and signal integrity. 1. Preliminary Design Preparation 1. Requirement Analysis Functional Requirements: Division of circuit functional modules (power supply, control, communication, etc.) Performance Indicators: Operating frequency, … Read more

For the layout of SMT components with small pin pitches such as QFP, QFN, and SOP, we sometimes encounter situations where adjacent pins of these components need to be interconnected. It has been observed that many designers, in an effort to save time, directly route the connection between the pads, effectively shorting the pins together. … Read more
