In the fields of mechanical processing, PCB design and product assembly, the design of holes is far more than just a round hole. Different types of hole structures have a direct impact on assembly accuracy, mechanical properties and even product appearance. Counterbore vs countersink are the two most common finishing hole types. Many technicians, purchasers,

What is Modular PCB Design? With the increasing complexity of electronic product functions, traditional single circuit board design has been unable to meet the needs of rapid iteration, flexible upgrades and efficient maintenance. In this context, the concept of “Modular PCB Design” came into being and gradually became an important trend in the electronics manufacturing

Introduction With the continuous improvement of global environmental awareness, green manufacturing has become an irreversible trend in the electronics industry. Major markets such as Europe and the United States have put forward stricter environmental standards for electronic products. Among them, ROHS PCB, as a basic compliance requirement, is playing the dual role of “pass” and

Introduction: The intersection of craft and art In stained glass works, each piece of glass is a narrative of light and shadow, and it is the shining metal welds that splice these fragments into a complete picture. Stained glass solder is not only an adhesive that connects each piece of glass, but also a tool

In modern electronic design, connectors play an irreplaceable role as bridges between modules. In particular, 4 pin connectors are widely used in consumer electronics, industrial control, automotive electronics, smart home and other fields due to their simple structure, diverse functions and flexible applications.
