What are the orientation options for Connectors?
PCB orientation is the relative position of two PCBs to be connected by BTB connectors. Here are some of the common orientations of BTB connectors:
In order to cater various PCB orientations (Parallel, Horizontal, Perpendicular), board-to-board connectors have been developed in straight, right angle and U-shaped designs.
How do we stack PCBs?
Amid the trends of miniaturization, transitioning to light weight and high speed, designers often face many constraints, both mechanically, and electrically. Greenconn offers various solutions to accommodate all stacking options.
Vertical - Parallel, Mezzanine - Both connectors are in a vertical orientation. This allows a PCB to be stacked on top of another, minimizing the surface area as a result.
Horizontal - 180 Degree, Coplanar, Edge-to-Edge - Both connectors are in a horizontal orientation. From the design standpoint, this keeps the mating centerline low profile to the PCBs.
Perpendicular - Motherboard to Daughterboard - Connectors are perpendicular to one another. This is commonly seen in hard drive applications where many "Daughterboards" are stacked onto one motherboard, allowing the data storage space to be efficiently expanded.
Here are some advantages of stacking PCBs: The design can be modularized into smaller PCBs and the PCBs can be connected using BTB connectors later on during assembly. This not only improves the design process but also allows modifications to be made easily.
From the assembly perspective, it can improve the manufacturability of the product, by operating with smaller PCBs rather than one large PCB.
Overall, properly stacking PCBs in layers can enhance the EMC (Electromagnetic Compatibility) of the design.
