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
Eutectic soldering, also known as low melting point alloy soldering, is a specific soldering technique. The process involves the removal of unstable oxide layers at the interface between the chip and the gold-plated base by gentle friction at specific temperatures and pressures, which causes the contacting surfaces to melt and form a liquid phase. Subsequently,

PCB encapsulation materials consist of substrates, interconnections, frames, interlayer media, and sealing materials. Among these, PCB encapsulation substrate materials serve as electronic components, primarily providing mechanical support, hermetic protection, and facilitating heat dissipation for electronic components and their interconnections.Substrate: High-density multilayer encapsulation substrates primarily serve as an electrical transition between semiconductor chips and conventional PCBs
Welding porosity is a common defect encountered in welding production, formed by the absorption and release of gases (primarily oxygen, nitrogen, and hydrogen) within the weld seam. It not only reduces the effective cross-sectional area of the welded component but also causes stress concentration, significantly lowering the strength and toughness of the weld metal. This
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
What is a dipole antenna? A dipole antenna is a basic antenna used to broadcast radio frequencies. A dipole antenna is named after the two conductors of equal length that extend from either side of the antenna. A dipole is an omnidirectional antenna, which means that it broadcasts frequencies in all directions at the same
