Find the Right Board-to-Board Connector by Specification
Board-to-board connector selection should start with real mechanical and electrical requirements. A reliable match depends on pitch, stack height, pin count, mating direction, signal speed, current path, tolerance and PCB assembly conditions.
Pitch & Density
Choose the pitch based on PCB space, signal density and assembly requirements. Current source data strongly supports 0.80 mm BTB families, with additional larger-pitch display connector options available from PPT materials.
Stack Height
Confirm the distance between two PCBs. Selected 0.80 mm series cover low-profile and taller mated-height options, including 5–10 mm and 5–25 mm stack-height ranges.
Mating Direction
Select vertical, side-entry, mezzanine or board-parallel structures according to the internal product layout, insertion direction and available mechanical space.
Signal, Power or Floating
Use standard signal BTB, high-speed signal BTB, power-signal hybrid or floating board-to-board connector options depending on electrical performance and assembly tolerance.

Board-to-Board Connector FAQs
What information is needed to select a board-to-board connector?
Please provide pitch, pin count, stack height, mating direction, PCB spacing, signal or current requirements, target series or part number, expected quantity and any available drawing or datasheet.
Can LinkManu review an alternative for an existing board-to-board connector?
Yes. Send the existing part number, drawing, datasheet or sample photos. Any possible alternative should be confirmed through dimensional, electrical, mechanical and application validation before use.
When should I use a floating board-to-board connector?
Floating board-to-board connectors are useful when the design has PCB misalignment, assembly tolerance, vibration or blind-mating requirements. Send the expected tolerance range for review.
Do you support high-speed board-to-board connector projects?
Selected source series list PCIe 3.0 / 8 Gbps and PCIe 4.0 / 16 Gbps capabilities. For actual projects, the connector, PCB layout, stack height and test conditions should be reviewed together.
Can pitch, pin count or stack height be customized?
Custom connector development may be reviewed based on target volume, tooling feasibility, electrical requirements, mechanical constraints and validation needs.
