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...
Project Background A manufacturing plant in California sought to reduce electricity costs through a distributed rooftop solar system while enhancing its green and sustainable corporate image. With ample rooftop space available, the company required a highly efficient MPPT solar controller capable of maximizing solar energy utilization and ensuring stable operation. The Role of PCBA Technology...

A variable power supply PCB is one of the most essential designs in electronic engineering, lab equipment, industrial systems, and embedded development platforms. It allows adjustable output voltage and current, making it suitable for testing, prototyping, and powering sensitive circuits. Designing a reliable variable power supply PCB layout requires careful consideration of power integrity, thermal...
With the development of electronic information technology, multi-layer PCB circuit boards are used in more and more fields. Traditionally, we define PCBs with more than four layers as “multi-layer PCBs” and PCBs with more than ten layers as “high-layer PCBs”. Whether or not a PCB manufacturer can produce high-layer PCBs is an important indicator of its...
There are some pretty amazing benefits to using flexible PCBs. Some of the advantages of flexible PCBs include the following: Reduced Space and Weight: Most of the advantages associated with flexible PCBs come from their low volume and weight. In fact, using a flexible PCB instead of a rigid PCB can result in a space reduction of over 50 percent and...
