SMT soldering process and technology are slightly different from through-hole technology. SMD soldering or surface mount technology assembly requires different SMT equipment and more experience and expertise. SMT PCBs have flat tin-lead or gold-plated copper pads without any holes. These traces are called “pads”. SMT Soldering Process Semi-solid solder called solder paste, which consists of very fine...
SMT vs. Through-Hole Technology – Which is better in terms of cost, assembly and reliability? This debate has been going on for several years. The advantages of SMT or surface mount technology over through-hole technology are in design and manufacturing. Surface mount components or SMD components are small in size and can be mounted on either...
At the heart of nearly every electronic product today is a printed circuit board (PCB), which supports and electrically connects the electronic components needed for an electronic device to function. Manufacturing a printed circuit board is a complex process that involves many steps that are different for every project. First, you need to design the board...
Customer Background: Our customer is a leading communication equipment company specializing in the development and manufacturing of high-frequency devices for 5G communication systems. Due to the high-frequency signal transmission requirements of their products, their PCB design demands extremely high signal integrity and strong anti-interference capabilities. Product Complexity: The primary challenge of this project was ensuring that the high-frequency...
Copper current density refers to the amount of continuous current going through a copper wire —whether on a PCB circuit board as a trace or not. According to the principles of Joule or Ohmic heating (represented as VI or I²R), any material that conducts electricity will generate heat, leading to a gradual rise in temperature...
In printed circuit board (PCB) design, the choice of pad type plays a critical role in determining the durability, reliability, and performance of the final product. Through-hole pads, which are designed for components with leads that pass through the PCB, offer superior mechanical and electrical connections compared to surface mount pads. This article explores the design steps for...
In printed circuit board (PCB) design, copper pads are points for attaching components with soldering. These pads come in two primary types: through-hole and surface-mount (SMD). Through-hole pads are designed for components with leads that are inserted through the pad’s holes and soldered on the opposite side of the board. This method ensures a mechanical and electrical bond between...
1. Customer Background The customer is a globally leading manufacturer of communication equipment, specializing in the development and production of large-scale routers, switches, servers, and high-speed networking devices. As modern network communications demand increasingly high signal integrity, reliability, and thermal stability, the customer required an 36-layer PCB with low-loss material (S1000-2M) and advanced immersion gold plating to ensure stable signal transmission...
