Abstract This paper examines the effects of common (shared) pads on printed circuit board (PCB) soldering processes and final product quality. As electronic devices continue to shrink in size while increasing in complexity, the use of shared pads has become more prevalent in PCB design. While offering space-saving benefits, common pads introduce several challenges to…
Introduction to PCB Via Repair Printed Circuit Board (PCB) vias are essential conductive pathways that connect different layers of a multilayer PCB. These small holes plated with conductive material allow electrical signals and power to travel between layers, making them critical components in modern electronics. When vias become damaged or fail, it can lead to…
Chip on board (COB), semiconductors place chips on printed circuit boards and achieve electrical connections between chips and substrates through wire stitching. The electrical connection between the chip and the substrate is achieved through wire stitching and covered with resin to ensure reliability. . Although COB is the simplest chip-on-chip technology, its packaging density is…
Abstract This paper examines the critical requirements for non-electrolytic nickel coatings on printed circuit boards (PCBs) in modern electronics manufacturing. As PCBs continue to evolve with higher density interconnects and more demanding operating conditions, the specifications for nickel surface finishes have become increasingly stringent. The discussion covers thickness requirements, adhesion standards, solderability, corrosion resistance, electrical…
I. Overview At present, the typical process of printed circuit board (PCB) processing adopts “graphic electroplating method”. That is, a lead-tin anti-corrosion layer is pre-plated on the copper foil part of the outer layer of the board to be retained, that is, the graphic part of the circuit, and then the rest of the copper…
As the carrier of various components and the hub of circuit signal transmission, PCB has become the most important and critical part of electronic information products. Its quality and reliability level determine the quality and reliability of the whole equipment. However, due to cost and technical reasons, a large number of failure problems have occurred…
1 Introduction When electronic engineers are doing reverse design or repair work on electronic equipment, they first need to understand the connection relationship between the components on the unknown printed circuit board (PCB), so they need to measure and record the connection relationship between the pins of each component on the PCB. The simplest method…
