APPLICATION

Automotive Board-to-Board Connector

Cockpit and ADAS domain controllers, automotive cameras and radar modules all stack sensor, compute and power boards with board-to-board connectors. Automotive adds vibration, wide temperature and long life to the consumer requirements.

Three typical automotive stacks

1) Domain controller: 0.4mm B118 (10–100 pins) between compute and interface boards for differential pairs and power; 0.8mm BB0098 (60 pins, 15mm) where the mechanical design needs a tall, wide stack. 2) Camera modules: 0.4mm B118 for space or 0.5mm B104 for structural height. 3) Power plus signal: 0.3mm B43 combines 12A power pins with signals, replacing one part and one placement step.

Metrics that matter in validation

Retention: no loosening after vibration and mating cycles; validate against the vehicle profile and re-measure contact resistance. Thermal cycling: from -40°C to high temperature, stress relaxation shifts contact resistance, so terminal material and plating matter. Life: automotive programmes typically require 30+ mating cycles within the resistance limit, with test reports on request.

Volume and traceability

Tape and reel for direct SMT, batch traceability and outgoing inspection reports per project, and sample plus data preparation ahead of PPAP.

FAQ

What validation can you support?

Insertion force, contact resistance, thermal cycling and vibration pre-validation with corresponding test data.

Which series for a domain controller?

Mainly 0.4mm B118 at 60 / 80 / 100 pins depending on signal count; 0.8mm BB0098 for stacks above 10mm.

How is power handled?

The 0.3mm B43 combines 12A power pins with signals in one connector, removing a part and a placement step.

Do you provide PPAP or inspection reports?

Outgoing inspection reports and batch traceability are available per project; PPAP documentation follows the customer template.
