PCB types and Applications

1. Rigid-Flex Board

Technical Features:

· Tightly assembled electronic packages, where electrical connections are required in 3 axes, such as cameras (static application).

· Electrical connections where the assembly is required to flex during its normal use, such as folding mobilephones (dynamic application).

· Electrical connections between sub-assemblies to replace wire harnesses, which are heavier and bulkier, such as in cars, rockets and satellites.

· Electrical connections where board thickness or space constraints are driving factors.

2. HDI Borad

Technical Features:

The HDI Board has finer lines and spaces, smaller VIAS and capture pads, and higher connection pad density than employed in conventional PCB technology. HDI PCB is made through Microvia and buried vias and sequential lamination with insulation materials and conductor wiring for higher density of routing.

5. Blind Buried Board

Technical Features:

A blind via connects exactly one outer layer with one or more inner layers. A buried via is a via between at least two inner layers, which is not visible from the outer layers. The advantage of Blind and Buried Board is that this technology offers a viable design technique to help meet the density constraints of lines and pads on a typical design without increasing the layer count or board size.

6. High frequency Board

Technical Features:

The increasing complexity of electronic components and switches continually requires faster signal flow rates, and thus higher transmission frequencies. Because of short pulse rise times in electronic components, it has also become necessary for high frequency (HF) technology to view conductor widths as an electronic component.

Depending on various parameters, HF signals are reflected on circuit board, meaning that the impedance (dynamic resistance) varies with respect to the sending component. To prevent such capacitive effects, all parameters must be exactly specified, and implemented with the highest level of process control.

Critical for the impedances in high frequency circuit boards are principally the conductor trace geometry, the layer build-up, and the dielectric constant (er) of the materials used.

7. Metal-Base Board

7.1 Cu-Base Board

9. Backplane Board

10 Layer Backplane Board

Backplanes are normally used in preference to cables because of their greater reliability. In a cabled system, the cables need to be flexed every time that a card is added or removed from the system; this flexing eventually causes mechanical failures. A backplane does not suffer from this problem, so its service life is limited only by the longevity of its connectors.
