Parallel Board-to-Board Connectors
Description
Horizontal SMT (HSMT) headers and sockets are ideally suited for low profile parallel board-to-board or board-to-component mating. The removable plastic cap provides the convenience of a traditional connector and once removed delivers an interconnect system with a minimal surface mount profile.
These sockets, 835-43-0XX-40-030001, and headers, 328-10-1XX-40-020001, are an excellent choice for applications where vertical board stacking is not an option, such as in LED lighting systems which often employ daisy-chained PCB’s to minimize overall package height. This series of HSMT connectors have an above-board profile of .096 in. with the cap in place and just .072 in. with the cap removed. The cap serves multiple functions: it maintains accurate pin to pin spacing, enables group placement of low profile SMT pins and receptacles and provides a flat pick and place surface for efficient automated assembly. After soldering, it may be easily removed to achieve a minimal profile.
The connectors are single row with .100 in. pin spacing and are available in 2-10 positions. All are packaged on tape and reel (1,450 parts per 13 in. reel) per EIA-481 standards; tape widths vary with pin count. The cap material is high temperature Nylon with an HDT of 260°C to withstand most soldering processes.
Each pin and receptacle are precision turned from brass alloy. The receptacle has a highly reliable 4 finger, beryllium copper contact and accepts leads ranging from .015 - .025 in. The standard plating for the sockets is tin on the shell and gold on the internal contact providing optimal interconnect reliability.
