SLM

Soft HT-SMD Foam Contact

Product Description

Laird Performance Materials’ HT-SMD is one of the Soft SMD (Surface Mount Device) Contact series which is used for circuit grounding and shielding of SMT (Surface Mount Technology) devices. This contact is designed to be solder reflow compatible and suitable for automatic processing.HT-SMD is composited of a tin/copper PI film over silicone foam.  SLM series is standard type with rectangular shape;  SSM series is similar t o SLM series but with lower compression force;  SLN series is hourglass or customized shape.
