Application:
The CLDM, Constrained Layer Damping Material, has three layers: a viscoelastic damping material, a polyester constraining layer, and a protective release paper. The CLDM material is designed to offer the maximum amount of structural damping to circuit boards and panel structures by shearing the highly damped viscoelastic layer.

Description:
The CLDM, Constrained Layer Damping Material, effectively and efficiently reduces the amount of vibration transmitted to a structure resulting in longer fatigue life of the structure or circuit board components. Typically, undamped structures have resonant transmissablities of 30:1 to 50:1 compared to the input. Systems using Constrained Layer Damping Material have transmissibilities of 3:1 to 10:1. This significant decrease in transmissibility directly correlates to a reduction in sound power transmission from the structure at resonance. Circuit boards can be ruggedized efficiently and cost effectively using CLDM without changes to the components.
