What is a Printed Circuit Board (PCB)
Printed circuit board, also known as printed circuit board, printed circuit board, often used in English abbreviations are PCB (Printed circuit board) or PWB (Printed wire board). PCB is the base plate used to assemble electronic components, and it is also the "mother of electronic products". It is a very important electronic component and a support for electronic components. Mainly through the metal copper foil circuits on the board, through the design of each layer to connect and conduct related components, to achieve a complete product that operates effectively.
Before the early PCB assembly service appeared, the various components of electronic products were connected by wires to form a complete path. Later, in order to simplify the manufacturing process of electronic products and reduce the cost, the circuit was developed by printing, and the copper foil on the substrate was used to replace the original wire connection, thereby improving the production efficiency.
The various components are mainly connected through the metal copper foil circuits on the board. By designing each layer to connect and conduct related components, a complete product that operates effectively is achieved.
Advantages and disadvantages of Blind and buried vias
Blind and buried vias can help you to meet the high
density constraints of lines and pads on a typical design without
increasing the overall layer count or your board size.The vias also
help you manage the printed circuit board aspect ratio and limit
the change of break out.
Cost is still the main issue with boards using blind and buried viasin PCB assembly service, compared to the boards using standard through hole vias. The high cost is due to the increasing complexity of the board and more steps in the manufacturing process. At the same time, testing and precision checks are made more frequently.Venture engineers can look at your engineering requirements, space needs and the functionality of your PCB to help you reduce costs with buried and/or blind vias.
