Today, let's learn about the various types of holes found on HDI PCBs. There are numerous types of holes used in printed circuit boards, such as blind via, buried via, through-holes, as well as back drilling holes, microvia, mechanical holes, plunge holes, misplaced holes, stacked holes, first-tier via, second-tier via, third-tier via, any-tier via, guard via, slot holes, counterbore holes, PTH (Plasma Through-Hole) holes, and NPTH (Non-Plasma Through-Hole) holes, among others. I will introduce them one by one.

As the prosperity of the PCB industry gradually rises and the accelerated development of AI applications, the demand for server PCBs is continuously strengthening.

As AI becomes the engine of a new round of technological revolution, AI products continue to expand from the cloud to the edge, accelerating the arrival of the era where "everything is AI".

The product we bring today is an optical chip substrate used on single-photon avalanche diode (SPAD) imaging detectors.

Bright red solder mask ink, gold plating + gold-finger surface treatment process of 30U', makes the entire product appear very high-end.

With the development of science and technology, information and communication technology is changing day by day, people's performance requirements for computers are getting higher and higher.

The main PCB supply chain has recently benefited from the demand for new product preparation.

As the demand for high-performance computing grows, the semiconductor industry is exploring new materials to enhance the speed and efficiency of chip integration.

In the context of semiconductor packaging, glass substrates are emerging as a key material and a new hotspot in the industry. Companies like NVIDIA, Intel, Samsung, AMD, and Apple are reportedly adopting or exploring glass substrate chip packaging technologies.

Today, let’s continue to learn the statistical problems and solutions of solder mask manufacture.

In the PCB solder mask process, sometimes we will have some production problems, today we will be part of the statistical problems and solutions for reference.

Paste mask. It is used for the SMT (Surface-Mount Technology) placement machine to place components. The template of the paste mask corresponds to the pads of all surface-mounted components, and its size is the same as the top and bottom layers of the board.
