Product details

40-Pin BERGSTIK® Breakaway for Board-to-Board Stacking

The solder tails carry a 150.0µin tin-lead finish, which reflows reliably in a standard SMT oven but is not RoHS-compliant for lead-free processes. With a 0.232" (5.90mm) mating pin length and 0.100" (2.54mm) insulation height, this header mates with standard low-profile socket strips and leaves enough clearance for a 1.6mm PCB stack.

Sourcing an Obsolete BERGSTIK® Header

The surface-mount solder tails require a solder-paste stencil aperture sized to the 150.0µin tin-lead finish — typical reflow profiles for SnPb solder apply.
