Fine-Pitch Board-to-Board Connectors for North American OEMs
North American hardware engineers usually begin with a parametric requirement - pitch, stack height, position count, current rating and mating cycles - and then look for a second source. This page maps those parameters to CPTGR series and shows how to obtain the CAD and compliance files needed for a design review.
How buyers in North America search
High-intent queries include "board-to-board connector manufacturer China", "0.4mm mezzanine connector", "DF40 alternative", "DF12 drop-in replacement", "BK13C06 cross reference" and "3D STEP model download" alongside "datasheet / footprint / free samples". Google carries the majority of search, with Bing meaningful on corporate desktops and inside Copilot.
procurement teams also check whether a supplier is the actual manufacturer. CPTGR is the factory, not a distributor: all BTB series are built on full Insertmold lines with plating after molding at our Dongguan facility, and cross-reference names are used only to describe compatibility intent.
Recommended series for North American programs
B118 (0.4mm, 10-100 pins, 1.5-4.0mm stack) and B104E/B104F (0.5mm, 10-80 pins, 3.0-5.0mm) serve camera modules, LiDAR modules, automotive board-to-board links and high-speed main-to-sub-board data connections. B09 covers 0.35mm / 6-60 pins / 0.6mm height, and BB0088 is a 0.175mm four-row BTB for extremely dense wearable or optical modules.
For RF, S01/S06 are RF test sockets rated to 11GHz for repeated production-line and final-test insertion; C01/C02/C03 are micro coaxial antenna connectors, a different category. FC0019 is a vertical drawer-type FPC connector that saves board area in compact modules.
Engineering package and commercial terms
Request the datasheet, 2D drawing, 3D STEP model, recommended PCB land pattern and stencil guidance for the target part number. At 0.4mm pitch and 100 pins we review coplanarity before reflow, aperture pull-back on a 0.10-0.12mm stencil, and ground-pin placement for return paths.
Standard samples are typically prepared in 3-7 days. MOQ, tape-and-reel packaging, Incoterms and compliance documentation are confirmed per part number at quotation. Custom heights, pin counts and plating are supported through OEM/ODM development.
Contact and response window
Our team operates on UTC+8. For North American buyers this means inquiries sent in the evening Pacific time are usually answered by the next morning. Use eng201@cptgr.com or +86 186 7678 9529, and include the stack-up, pin count and incumbent part number to receive a part-number-level reply.
The part number index (220 part numbers) and the cross-reference table are static, login-free pages, suitable for sharing internally during a component review.
FAQ
Are you a manufacturer or a distributor?
CPTGR is the manufacturer. Production, molding, plating and assembly are performed at our Dongguan facility.
Can you support a second-source qualification?
Yes. Send the incumbent part number and drawing; we return the mapped CPTGR pair, dimensional comparison and sample plan.
What CAD formats do you provide?
3D STEP models, 2D drawings and recommended footprints are supplied on request for the relevant part numbers.
What are typical sample and production lead times?
Standard samples are typically prepared in 3-7 days. Production lead time is confirmed at quotation based on pin count, plating and quantity.
