Working with G10-ESD AS-SURF

Is G10-ESD easy to machine?

Machine dry with carbide or PCD tooling, high speed / moderate feed, sharp edges and rigid clamping; extract the abrasive glass dust and expect tool life well below that of plastics.

Can G10-ESD be welded?

Not weldable — thermoset laminate; join by bonding with epoxy/acrylic structural adhesive or by mechanical fasteners with washers to spread load.

Can G10-ESD be formed, bent or molded?

Supplied fully cured as flat sheet, rod or tube; no post-forming possible, so all geometry comes from machining, waterjetting or punching (thin sheet only, heated punch).

What surface finishes work on G10-ESD?

Edges should be deburred and sealed with epoxy to limit moisture wicking; no plating or anodizing — for coated antistatic grades avoid sanding or solvent wiping the functional surface.

G10-ESD AS-SURF — frequently asked

What is G10-ESD AS-SURF used for?

G10-ESD AS-SURF is typically used for ESD assembly jigs, PCB test and probe fixtures, board-handling nests and locating plates, insulating standoffs in electronics test rigs, static-safe magazine rails and guides and machine tooling and mounting plates. In short: static-dissipative G10.

What is the tensile strength of G10-ESD AS-SURF?

G10-ESD AS-SURF has a typical tensile strength of 300 MPa (43.5 ksi) — stronger than 53% of composite grades. Strength varies by condition: see the 5 listed tempers.

Is G10-ESD AS-SURF easy to machine?

Not especially — machinability is rated fair (40/100, better than 57% of composite grades). Machine dry with carbide or PCD tooling, high speed / moderate feed, sharp edges and rigid clamping; extract the abrasive glass dust and expect tool life well below that of plastics.

Can G10-ESD AS-SURF be welded?

Not readily — weldability is rated not recommended (0/100). Not weldable — thermoset laminate; join by bonding with epoxy/acrylic structural adhesive or by mechanical fasteners with washers to spread load.

What surface finishes work on G10-ESD AS-SURF?

Edges should be deburred and sealed with epoxy to limit moisture wicking; no plating or anodizing — for coated antistatic grades avoid sanding or solvent wiping the functional surface.

Can G10-ESD AS-SURF be formed, bent or molded?

Supplied fully cured as flat sheet, rod or tube; no post-forming possible, so all geometry comes from machining, waterjetting or punching (thin sheet only, heated punch).

What is the maximum service temperature of G10-ESD AS-SURF?

G10-ESD AS-SURF is rated for continuous use to about 130°C (266 °F), and briefly to 155°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
