Due to their high routing density and excellent space utilisation, double sided pcbs are widely used in various electronic products. However, their dual-sided layout and metallised via structure place higher

The layer-up strategy for multilayer PCBs directly determines signal integrity, power supply stability and electromagnetic compatibility (EMC), and is a core skill that hardware engineers must master. A well-designed layer-up

BGA packaging has become the mainstream form of integrated circuit packaging due to its high density, high reliability and excellent electrical and thermal performance. Compared to traditional DIP and QFP

A BGA substrate (Ball Grid Array Substrate) is the core carrier of a ball grid array package; essentially, it is a high-density interconnect (HDI) multilayer PCB used to mount the

A bare PCB serves as the core framework of a traditional circuit board; its fundamental function is to guide the flow of current through carefully designed circuit paths, and it

In the design of power adapters, the quality of the PCB routing on the bare PCB directly determines the stability, reliability and electromagnetic compatibility (EMC) of the entire unit. A

The Physical Framework and Operating Limits of Relays Electronic components As the progenitor of “weak current controlling strong current” in the electronics industry, the core value of relays lies in

Printed circuit boards (PCBs) are the core components of modern electronic products, and their manufacture relies on a key base material: copper-clad laminate (CCL). Depending on product form and application,

The soundness of RF board layout directly determines the transmission quality of RF signals, interference immunity and the overall performance of the equipment; it is a core aspect of RF

In today’s rapidly evolving technological landscape, drones have become deeply integrated into every aspect of daily life and industrial production, emerging as indispensable smart devices. At the heart of a

The key difference between leaded solder and lead free solder processes lies in the lead content of the solder. According to the EU RoHS Directive, lead content must be below

As PCBs evolve towards being lighter, thinner, smaller and more compact, rigid flex boards (also known as rigid-flex assemblies) have emerged as a key technology for reducing the size and

As IC pin densities increase and signal frequencies rise, the choice of PCB surface treatment process has become particularly critical. Gold plated circuit boards were once favoured for their high

What is FCT testing? The core principle of FCT (Functional Circuit Test) is to treat the PCBA as a complete functional module, simulate its actual operating environment within the end

The defining characteristic of rigid PCBs (rigid printed circuit boards) is that they are ‘non-flexible’; relying on their rigid substrate, they provide stable support and electrical connection pathways for electronic

IC packaging involves encapsulating the bare die—cut from a wafer—into a complete component that can be directly mounted onto a PCB. It fulfils three fundamental functions: establishing an electrical connection

What is a RF PCB? Put simply, a RF PCB is a printed circuit board specifically designed for the transmission and control of radio frequency and microwave signals. Within the

In the field of PCB design and assembly, through hole PCBs remain a core technology—even though surface-mount technology (SMT) now dominates most modern devices. Many engineers still opt for through

As electronic products continue to evolve towards lighter, thinner designs and higher levels of integration, hardware design is no longer confined to simple two- or four-layer boards. 6 layer PCBs
