With the continuous development of science and technology, PCB board industry is also moving forward, technology upgrading has become a key element of the development of the industry...

The interlayer bonding quality of PCB multilayer boards is the decisive factor in preventing failures such as delamination, blistering, and peeling. The core of this bonding process lies in the selection of prepreg (PP) and the control of lamination parameters. Most mass production defects in multil

Many hardware engineers face the same dilemma at the very start of a PCB layout: how many layers should I use? Should I save cost with a 2-layer board, or go straight to 4 or even 6 layers?In reality, there’s no mystery here. The core principle is simple: use the minimum number of layers that meets

In high-volume PCB manufacturing, the vast majority of mass rework and scrap incidents do not originate from process fluctuations at the fabrication site, but rather from latent Design for Manufacturability (DFM) defects introduced during the design phase. Many hardware engineers focus solely on mee

Many hardware engineers directly apply the Design Rule Check (DRC) settings of standard 1oz six-layer boards to 2oz or 4oz heavy copper multilayers. A common mistake is retaining inner layer trace/space rules at 4mil/4mil. Post-prototype, this leads to two typical failures:Open circuits caused by ov

Controlling impedance in four-layer blind/buried via designs isn't just about adjusting trace width; the synergistic design of the blind via structure, dielectric thickness, and inner reference planes is paramount. Even if trace widths perfectly match simulation parameters, excessive antipad sizes o

High-speed digital chips feature low core voltages, rapid transient current changes, and severe load fluctuations. Core devices such as CPUs, FPGAs, and high-speed buses are extremely sensitive to power supply noise, voltage ripple, and transient voltage drops. High-layer-count PCBs offer advantages
