It holds and connects all components. Indeed, the “drill” process is a vital step in making PCBs. It is a stage where accuracy is … Continued
The Impact of PCB Warping on PCBA Quality PCB designing is the very begaining of PCB fabrication. PCB warping, a common issue in electronic manufacturing, significantly compromises the quality and reliability of PCBA (Printed Circuit Board Assembly). When warping exceeds 0.75% of the board length (e.g., >2.1 mm for a 300 mm board), it directly … Continued
Standard pcb board thickness is 1.6mm, for circuit surface finishes, there are mainly 4 kinds. In this artical, we will introduce the difference between them. Advantages and Disadvantages Printed Circuit Board (PCB) surface finishes are critical coatings applied to protect copper traces from oxidation and ensure solderability during assembly. The choice of finish significantly impacts … Continued
The Differences Between FPC Layout and PCB Layout FPC Layout, as the core of flexible printed circuit board design, differs significantly from rigid PCB Layout in terms of design concepts, application scenarios, and the stability of the final product performance. Generally speaking, the performance of rigid PCBs in products is usually more stable, and this … Continued
PCB and PWB are often heard in the realm of electronics manufacturing. While frequently used interchangeably, a subtle but important technical and historical distinction exists between them. The Historical Origin of PCB and PWB The term Printed Wiring Board (PWB) is actually the older name. It was coined to describe the core function of the board: … Continued
Differences Between PTH PCB and HDI PCB PTH PCB is the main product of Printed Circuit Boards (PCBs), which are essential in electronics, along with High-Density Interconnect (HDI) PCBs representing distinct technologies catering to different needs. Technology and Structure: PTH PCB rely on mechanically drilled through-holes (typically >0.2 mm in diameter) coated with copper to … Continued
The standard FPC lamination is a critical manufacturing process that involves bonding multiple layers of materials under controlled heat and pressure. This procedure is essential for creating reliable and high-performance flexible printed circuit boards (FPCs). Which we use widely in modern electronics due to their lightweight and bendable nature. It also has a close relation … Continued
PCB Potion, we also call it the magic of electronic potting. In the intricate world of electronics manufacturing, reliability is paramount. Potting is one of the most crucial, yet often unseen, guardians process of this reliability. The material used for this—the PCB potion—is far from a magical brew. however, its protective qualities are indeed transformative … Continued
