BOARD TO BOARDConnectors (BTB Sockets & Headers) · 10 models

A board to board connector (BTB connector) mates two circuit boards directly without a cable, for stacking a daughter board on a main board, a module on a carrier, or a display module on a control board. The KINGCONN BOARD TO BOARD series has 10 models: sockets (SOCKET) and headers (HEADER) at 0.4mm, 0.5mm, 0.8mm and 1.27mm pitch, including side-entry and right-angle types, with mated heights from 0.80mm to 15.0mm and 10 to 200 pins — each with a downloadable engineering drawing on its part page.

How do I request a drawing or samples for BOARD TO BOARD?
Email service@kingconn.com.tw with the part number. Clicking any part card on a product page also pre-fills the enquiry subject with that part number. Our sales team will reply with the drawing, samples and pricing.
Can BOARD TO BOARD be customised?
Yes. The Taoyuan R&D team covers the full path from design and tooling to volume production, including medical-device ODM experience. Send us the application and the requirement, and sales and engineering will assess it together.
How do I choose the pitch of a board to board connector?
By board space, pin count and current: 0.4mm and 0.5mm pitch save the most space for handheld devices and small modules; 0.8mm is the most common pitch on industrial PCs and embedded boards; 1.27mm has heavier terminals for higher current or mechanical strength. The KINGCONN BOARD TO BOARD series lists all four pitches.
How is the mated height of a board to board connector determined?
Mated height is the gap between the two boards once socket and header are mated, set by the combination of socket height and header height; the part descriptions in this series state H (body height) and MATING HEIGHT, all taken from the drawings. Email both the socket and header part numbers to service@kingconn.com.tw and sales will confirm the combined height.
Is there a drawing for each board to board connector?
Yes. Click any part card on this page to open the part page and download its engineering drawing (PDF); the dimensions, materials and plating in our spec tables are transcribed from those drawings.
