High Parallel Testing of Mobile PMIC in WLCSP Package In this article, we introduce the high parallel testing of mobile PMIC in WLCSP package. During this process, we illustrate the testing of a small chip that integrates a lithium-ion charger, a micro USB interface controller, RGB, and LED drivers. We also compare and explain the … Read more
Abstract This article discusses the definition of EMC, testing methods for microcontroller application systems, the application of new EMC devices and materials, and troubleshooting techniques. Anyone involved in the research, development, production, or supply of electronic products must conduct EMC electromagnetic compatibility testing. Introduction EMC, or Electromagnetic Compatibility, refers to the ability of a device … Read more
01 Core Standards: Technical Requirements and Testing Framework GB/T 9813.1-2016 focuses on “functionality, reliability, and safety,” clearly defining the mandatory and optional testing items for desktop computers, which include: Basic Performance: CPU computing power, memory read/write speed, hard disk storage performance (e.g., SSD random IOPS); Structure and Appearance: Shell materials (e.g., impact resistance of metal/plastic), … Read more
Following the previous SOC test cases, which garnered significant attention, we will add some considerations for PMIC testing. Combining the previously discussed requirements for PMIC, this article will provide a preliminary discussion from a testing perspective: after the definition and design of the PMIC, how to conduct testing. There is a wealth of information available … Read more

In embedded IoT development, the MQTT protocol has become the standard choice for communication between devices. Why do you need a local MQTT server? • Development Testing Isolation: Avoid impacting the production environment and provide a secure testing space. • Network Independence: Does not rely on external network connections, ensuring a stable development environment. • … Read more
Component costs account for 40%-60% of the total PCBA cost, and even a small decimal error can lead to losses in the tens of thousands. In electronic product design, accurately estimating PCBA costs is crucial for assessing project feasibility and controlling profit margins. Whether you are a hardware engineer, procurement specialist, or a startup founder, … Read more
