Board-to-Board Stacking Connectors from China
1 resources tagged with "Stacking Connector"
Stacking connectors are board-to-board (BTB) connectors that join two PCBs in parallel at a fixed mating height — common in stacked module designs, camera assemblies, and compact IoT boards. Chinese suppliers offer both OEM-original parts (Hirose, JAE, Molex) and clones, with stack heights typically in the 0.8-5.0 mm range and pitches down to 0.35-0.4 mm. Fine-pitch parts are where clones get risky: contact alignment and retention force drift, causing intermittent connections after a few mating cycles.
When sourcing stacking connectors, the spec that matters most is mated stack height and pitch — both must match the original exactly or your boards won't seat. The common pitfall is buying a fine-pitch clone to save cost and getting contact resistance or mechanical retention that fails reflow or field vibration.

FAQ
Are Chinese BTB connector clones reliable?
For coarse pitches (0.8 mm and up) good clones are usable; below ~0.5 mm, alignment and retention tolerances often slip and intermittent contact appears. Validate with mating-cycle and contact-resistance tests on samples before committing.
How do I match a stacking connector's height?
Specify the mated stack height (board-to-board gap) and pitch from the original datasheet — these are fixed by the connector pair and must match for the boards to seat correctly. Send the supplier the exact OEM part number you're cross-referencing.
