BM20 0.4 mm Pitch Board-to-Board/Board-to-FPC

Hirose's 0.4 mm pitch, 0.8 mm stacking height, FPC-to-board-connectors with no restriction on pattern design

Image of Hirose's BM20 SeriesThe BM20 series from Hirose Electric is a 0.4 mm contact pitch board-to-board / board-to-FPC connector with a stack height of 0.8 mm. There is no restriction on pattern design, as the thin molding technology maintains the effective mating length of 0.2 mm while achieving complete insulation between the bottom side of the connector and the board.

The BM20 series has a mating self-alignment of 0.3 mm which is secured by the guide ribs. It has a shock-absorbing configuration with a dimple on the contact for connector robustness. This series is RoHS-compliant and Halogen-free and is available in positions 10, 20, 24, 34, and 40.

Features
  • Space saving: 2.3 mm depth
  • 0.7 mm pick-up depth accepts universal vacuum pick and place nozzle
  • Highly reliable 2-point contact and retention force with clipping contact design
  • Area beneath the connector is available for patterning
  • Enhanced self alignment mechanism by guidance ribs (self alignment range: 0.3 mm)
  • Shock-absorbing configuration with dimple on contact for robustness
  • Clear tactile click with excellent contact design
  • Supports USB 3.1 gen.2 (10 Gbps) transmission
  • Solder wicking prevention
  • Contact protection against dust
  • RoHS compliant; Halogen-free product
Applications
  • Portable audio
  • Notebok PC, table PC
  • Mobile phone, smart phone
  • DSC, DVC
  • Game machine
