About The HDI PCB

Due to the influence of drilling tool, the cost of traditional PCB drilling is very high when the drilling diameter reaches 0.15mm, and it is difficult to improve again. The drilling of HDI PCB board no longer depends on the traditional mechanical drilling, but uses laser drilling technology. (so it is sometimes called laser plate.) The drilling hole diameter of HDI PCB board is generally 3-5mil (0.076-0.127mm), and the line width is generally 3-4mil (0.076-0.10mm). The size of pad can be greatly reduced, so more line distribution can be obtained in unit area, resulting in high-density interconnection.

The emergence of HDI technology adapts to and promotes the development of PCB industry. So that more dense BGA and QFP can be arranged in HDI PCB board. At present, HDI technology has been widely used, of which the first-order HDI has been widely used in the production of 0.5 pitch BGA PCB.

The development of HDI technology promotes the development of chip technology, which in turn promotes the improvement and progress of HDI technology.

At present, BGA chip of 0.5pitch has been widely used by design engineers, and the solder angle of BGA has gradually changed from the form of center hollowing out or center grounding to the form of center signal input and output needing wiring.

Advantages Of Blind Via And Buried Via PCB

The application of blind and buried via PCB can greatly reduce the size and quality of PCB, reduce the number of layers, improve the electromagnetic compatibility, increase the features of electronic products, reduce the cost, and make the design work more convenient and quick. In traditional PCB design and machining, through hole will bring many problems. First of all, they occupy a large amount of effective space. Secondly, a large number of through holes in one place also cause a huge obstacle to the routing of the inner layer of multi-layer PCB. These through holes occupy the space needed for routing. And conventional mechanical drilling will be 20 times as much work as non-perforating technology.
