MSI Assemblies

Meritec’s MSI assemblies have set the standard for reliable multi-signal cable assemblies. Our proven manufacturing process provides both controlled impedance and point to point assemblies that mate with industry standard headers. Utilizing LCP molding compounds and FEP ribbon cables, these assemblies provide superior performance over IDC cables. In addition to being qualified for aircraft flight applications, their high heat resistance makes them applicable for use in Test and Burn-in stations or other harsh environments.
