NEMA LI-1 & MIL-I-24768

Our fabrication capabilities are extensive, boasting 3, 4, and 5-axis milling on parts up to 30” x 40” x 40” with 7 micron tolerance (0.0003”). We also offer CNC 3 and 5 axis routed parts up to 60” x 120” and precision cut-to-size panels or blanks. Our proprietary precision grinding process can achieve 0.0005” flatness and thickness tolerances with finishes that rival or surpass traditional lapping for composite materials.

Through our partnership with Vericut we can digitally run your part before it even gets to a machine to verify accuracy, and through our Keyence-equipped 8200 square foot quality laboratory, we can verify accuracies and tolerances in seconds.

N.E.M.A. grades G10 and FR4 Glass Cloth Reinforced Epoxy Natural color is typically yellowish to light green. The most versatile all-around laminate grades are continuous glass woven fabric impregnated with an epoxy resin binder. (Epoxy resins are among the most versatile and widely used plastics in the electronics field, primarily because water absorption is virtually nil, rendering it an outstanding insulator. Beyond its electrical insulating properties, epoxy resins exhibit superior adhesive properties and great dimensional stability - shrinkage is usually less than 1 percent). G10 andFR4 have extremely high mechanical strength, good dielectric loss properties, both wet and dry. The main difference between N.E.M.A. GradesG10 and FR4 is that FR4 is a fire-retardant grade of G10. Therefore, FR4 may be substituted where G10 is called out except in applications where halogens are not desired. G10 can never be substituted where FR4 is called for. (G10 certifies to Mil-I-24768/2 GEE; FR4 certifies to Mil-I-24768/27 GEE-F.)
