As a leading supplier and pioneer of device connection technology, Weidmüller offers the broadest range of products that is available for the SMT process. Our connection elements are handled fully automatically together with the component assembly in a single manufacturing process, which reduces your manufacturing costs. In addition, we assist you throughout the design-in process with products, in-depth knowledge of applications and proven solutions expertise.
With their short pin length of 1.50 mm, our components free up more space and allow greater design freedom, while meeting the requirements of IPC-A-610 E (7.3.3, Table 7-3, Note 1). With a PCB thickness of 1.60 mm, you benefit from double-sided assembly. The option of vapour-phase soldering is also available, since no drops of solder paste form on the underside of the circuit board. Our simplified paste application process and minimised paste volumes also reduce your manufacturing costs. The optimum temperature absorption and trouble-free degasing of the flux in the soldering process also contribute to cost-efficient PCB assembly.
We manufacture our THR components from the high-performance plastic LCP to ensure reliable, problem-free use on your printed circuit boards. You can use these halogen-free, high-temperature-resistant components in all common soldering methods and benefit from their outstanding dimensional stability and accurate grid alignment. With their extremely low moisture sensitivity level (MSL 1), you can store the components indefinitely and use them in the assembly process without pre drying. Our components remain dimensionally stable even at high operating temperatures and fit snugly on the PCB.
With a position tolerance of less than ± 0.1 mm around the zero position, our solder pins exceed the requirements of the IEC 61760-3 standard. Due to our advanced manufacturing methods, our high-precision pin connectors are ideally suited for use in automated assembly. The contact pin is positioned and checked with the utmost care. Our dimensionally stable pin headers thus assure you of a seamless THR process without downtimes.
For particularly fast and stable fixing to the circuit board, you no longer need any additional screws. With our solder flanges, you solder the connection components to the contact pins in a single step in the reflow process. Time-consuming steps involving screws are no longer required. In addition, the geometry and positioning of the solder flange protects the solder joints against long-term mechanical stress and prevents them from being put under strain when screws are tightened.
Reduce the number of items, the time spent on data administration and the storage space required to a minimum. Thanks to their modular structure, our SL-SMarT pin headers with THR solder connections can be combined using any number of two- and three-pin components. Since you only need two conveyor systems, you optimise use of the available feeder space. Especially for circuit boards with different, multi-pole pin headers, the processing rate and cost optimisation achieved with the SL-SMarT are unrivalled.
