Q1:What is a Rigid-Flex PCB?
A1: A Rigid-Flex PCB is a hybrid board that consists of a combination of rigid and flexible printed circuit boards. These boards are designed by combining flexible circuit boards with one or more rigid boards.
The flexible part of the board is usually used for providing interconnections between rigid boards, which allows narrow conductor lines which take up less space making the boards smaller. Using flexible PCBs for interconnections also eliminates the need for connectors, which are bulky and heavy making rigid-flex printed circuit boards much lighter. Interconnections using flexible PCBs over connectors also provide lower losses and accommodate controlled impedance and eliminate connection problems such as cold joints.
Another major advantage of Rigid-Flex boards is the use of different substrate materials in different sections on the board. Some sections of the board might require high performance substrates which are expensive while others sections might not could use a standard FR-4 substrate. This flexibility in terms of substrate selection can optimize the performance and cost of Rigid-Flex PCBs.
Designers often use Rigid-Flex PCBs as they provide a lot of design flexibility. These boards are also more cost effective than flexible PCB boards.
Q2: What is DRC in Printed Circuit Boards?
A2:Design Rule Checking (DRC) is a process used to identify errors and mismatches such as spacing & trace widths in a PCB design/layout. The layout of a PCB board is designed using software, each PCB fabricator has a set of rules which they publish that specify various parameters such as what the spacing between each line should be, the minimum size of vias, the width of a line etc.
Once a design is submitted to a PCB Fabricator, they run a DRC test to ensure that the submitted design complies with their published standard. This ensures that the PCB will be fabricated to spec. If there are any mis-matches the DRC points them out and the designer then updates the design/layout accordingly. DRC (Design Rule Checking) is a must to ensure there are no design violations in the PCB. This check is done prior to the manufacturing of the final board.
The Design Rules are different for each PCB manufacturer. Users should check the design rules of a PCB fabricator before submitting a PCB Design to the manufacturer.
