How close can components be placed on PCB?
Keep at least 40 mils of space between all of your parts. Why? Each footprint that you place on your PCB contains a set of copper pads that will have an electric connection.
Why do we need to have a high consideration on the proper component placement in our PCB?
PCB component placement affects everything from testing and accessibility to functionality and performance. Therefore, when designing a PCB, it is a requirement that components fit together in a specific way. For example, your components need to be near their connected circuitry to provide electrical functionality.
Which is the correct alignment for a PCB?
Quite simply, the ideal for component alignment is to group together similar or identical Component Packages, and to specify the same orientation for each of these, throughout the grouping, as shown in the picture below. For example: all QFP packages are placed in a row, with Pin 1 at the top left-hand corner for each IC.
What should I know about component orientation on PCBs?
Marking orientation: Assuming that the component is oriented correctly to begin with, you can create a huge problem if your silkscreen marking is incorrect. Please make sure that your polarity indicators are marking the correct pins.
Is it safe to place components on the edge of a PCB?
However, if you do need to avoid placing components on the edge of your board because of assembly restrictions then make sure that all of your parts and traces are at least 20 mils away from the edge of your PCB. An example of a PCB panel, which gets snapped off after the board is complete.
What happens to passive parts on a PCB?
Passive parts with unbalanced metal connections between their two pins run the risk of floating on their pads or standing up in an effect known as “tombstoning” during solder reflow. Another concern is the orientation of parts near the edge of the PCB.
