Overview of the YFW Series Stacker

The YFW series elevated open-pin-field stackers by Samtec are precision-engineered interconnect solutions designed to mate with the company’s YFS series. These stackers are notable for their 1.27mm (0.050″) pitch, variety in number of rows (five, eight, or ten), and choice of stack heights. They are made to facilitate pitch-matched stacking of printed circuit boards (PCBs). The insulator material is Black Liquid Crystal Polymer and the terminal material is brass, with a plating of gold (Au) over 50 microinches (1.27 micrometers) of nickel (Ni).

Key Specifications

The operating temperature range for the YFW series stackers is from -55°C to +125°C, accommodating a broad span of environmental demands. All models in the series are RoHS compliant, ensuring adherence to current environmental and safety standards, but note that the series is not lead-free solderable. Recognition credentials and the complete scope of recognitions can be accessed via Samtec’s quality webpage.

Product Options

All products in the YFW series offer flexibility in customization. The available options include tin-lead solder balls for assembly, choice in number of pins per row, lead style, plating option (specifically, 30 microinches of gold on post), and row options (five, eight, or ten rows). Auxiliary options such as polyimide pick and place pad and tape & reel packaging are available for certain models.

Mating and Mechanical Information

The YFW stackers are designed with polarization to ensure correct mating. Varying stack heights are offered, ranging from 5.00mm (0.197″) up to 25.00mm (0.984″), which should be chosen based on application-specific requirements. It is important to consider that processing conditions may affect the mated height; specifications for this can be found under the YFT series.

Important Notes

Buyers should be aware that some sizes, styles, and options are considered non-standard and non-returnable. Ongoing technical progress may result in design, specification, and component changes without notice, as mentioned on the Samtec website.
