In modern electronics manufacturing and testing, especially in the semiconductor industry, the load board is a crucial yet often overlooked component. It acts as a “bridge” and “extended stage” between the chip tester and the chip under test (DUT), playing a key role in ensuring chip performance, quality, and reliability. Read more
Introduction Within the intricate circuitry of high-performance electronic devices like smartphones and laptops, countless miniature chips are securely attached to printed circuit boards (PCBs) using sophisticated interconnection technologies. Among these, Ball Grid Array (BGA) assembly has emerged as a pivotal process for high-density, high-performance chip mounting, establishing itself as an Read more
What is an HDI PCB? – The Backbone of Modern Electronic Devices HDI PCBs (High-Density Interconnect Printed Circuit Boards) are among the most critical fundamental components in today’s electronics industry, representing the forefront of printed circuit board technology development. HDI refers to circuit board design and manufacturing technology that utilizes Read more
In PCB design, exposed copper refers to the area of copper foil directly exposed, not covered by solder mask. Typically, PCB surfaces are coated with a solder mask to protect the copper foil from oxidation, prevent short circuits, and improve overall reliability. However, in certain functional areas, the copper foil Read more
