ENGINEERING THE IMPOSSIBLE

Specs & Parameters
Design & Material Spec Sheets

Delmat Material has excellent machinability and will maintain mechanical properties at soldering temperatures. This material will not pick up solder and is resistant to the chemicals in flux and solvents, including MEK and acetone. Tests conducted with temperature profiling devices show an even thermal distribution across the PCB. The monolithic sheet construction of Delmat means it will not delaminate when exposed to repeated chemical and temperature changes.
