Product Description

With the development of portable product design in the direction of miniaturization and high density, the difficulty of PCB design is becoming greater and greater, placing higher requirements on the production process of PCB. In most portable products, the BGA package with a pitch of 0.65mm or less uses a blind buried via design process, so what is a blind buried hole?
Blind holes: Blind vias are the type of vias that connect the inner wiring of the PCB to the surface wiring of the PCB. This hole does not penetrate the entire board.
Buried holes: Buried vias only connect vias between inner layers, so they are not visible from the PCB surface.

HDI is the English abbreviation for High Density Interconnector. High-density interconnect (HDI) manufacturing is one of the fastest growing areas in the printed circuit board industry. From the first 32-bit computer from HP in 1985 to the large client server with 36 sequential multi-layer printed boards and stacked micro-vias, HDI/mini via technology is undoubtedly the future PCB architecture. Smaller ASICs and FPGAs with smaller device spacing, I/O pins, and embedded passives have shorter rise times and higher frequencies, all of which require smaller PCB feature sizes, which drives Strong demand for HDI/mini vias.

Printed circuit boards abbreviation as PCB. A conductive pattern which is formed on a dielectric material in a predetermined design to form a printed circuit, a printed component, or a combination of the two is generally referred to as a printed circuit. And a conductive pattern that provides electrical connection between components on an insulating substrate, called printed circuits.

PCB characteristics
● High density. For decades, the high density of printed boards has grown with the increased integration of integrated circuits and advances in mounting technology.
● High reliability. Through a series of inspections, tests and aging tests, the PCB can be reliably operated for a long period of time (usually 20 years).
● Designability. For the various performances of PCB (electrical, physical, chemical, mechanical, etc.), the design of printed boards can be realized through design standardization and standardization, with short time and high efficiency.
● Productivity. With modern management, it can carry out standardization, scale (quantity), automation and other production to ensure product quality consistency.
● Testability. Established relatively complete test methods, test standards, various test equipment and instruments to detect and identify PCB product qualification and service life.

● Assemblyability. PCB products not only facilitate the standardized assembly of various components, but also can be automated, large-scale mass production. At the same time, the PCB and various component assembly components can be assembled to form larger components and systems up to the complete machine.

● Maintainability. Since PCB products and various component assembly components are produced in a standardized design and scale, these components are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the system can be quickly restored. Of course, you can say more about it. Such as miniaturization and weight reduction of the system, high-speed signal transmission, etc.
