Advantages Of Mezzanine And Coplanar Connection In Unshielded Board-to-board Connectors With 1.27 Mm

By: Phoenix Contact (SEA) Pte. Ltd.
EUNOS, Singapore - July 31, 2020 - PRLog -- As automation and the IoT things transform industrial environments, demand is increasing for electronics with interfaces for signal, data, and power transmission, as well as shielding from harsh environmental conditions. Coplanar connections use horizontal female and male connectors to connect coplanar PCBs where as Mezzanine connectors. Combine vertical female and male connectors to connect stacked PCBs.

Board-to-board connectors are an important component in the fourth industrial revolution. Board-to-board connectors with 1.27 mm pitch enable the robust PCB connections within the device. This allows you to design PCB orientations flexibly. Implement mezzanine and coplanar connections, mother-daughter cards, and connections with flat-ribbon cable. Unshielded board-to-board connectors with a 1.27mm pitch can be suitable for stacking, pre-assembled female connectors with flat ribbon cable can also enable wire-to-board applications, which can help accommodate larger PCB spacings.

0.8mm- and 1.27mm-pitch board-to-board connectors ( provide PCB designers with more flexibility when connecting several PCBs in industrial electronic devices. These robust contact systems also allow for different PCB arrangements and stacking heights, which results in greater support for flexible and modular device designs. As field devices become smaller, more modular, and more intelligent, device manufacturers can obtain tested and reliable device interfaces for the transmission of signals, data, and power from a single source. Thanks to these highly adaptive devices, the intelligent factories that serve as the backbone of Industry 4.0 are fast becoming a reality in markets around the world.

FINEPITCH 1.27 mm – Advantages

Continuously reliable contact
: The gold-plated contact surface enables high number of (up to 500) insertion and withdrawal cycles, performance level 1.

Stable soldering: Anchor metals ensure that the connection to the PCB is mechanically stable.

Protection from vibrations: Latching on both sides prevents connections from coming loose due to vibrations.

Reliable connection: Lead-in chamfers ensure that male and female connectors are guided and engage correctly.

Mismatching prevented: Polarization prevents female and male connectors from being rotated 180° before being connected to each other.

Process-reliable soldering: Female and male connectors feature a coplanarity of very less value (usually ≤ 0.1 mm).

Securely positioned: Positioning pins on the bottom ensure secure positioning on the PCB.

Process-compatible packaging: The female and male connectors are supplied in tape-on-reel packing, connectors without cables are supplied in tray format, and pre-assembled connectors are supplied in a bag.

Automated soldering: The PCB connectors are soldered using the SMT method. Overhead soldering and Automatic Optical Inspection (AOI) are also possible.
