Mechnano Develops First Nano-Uniform ESD, High-Temp 3D-Printable Resin

In a recent case study, Mechnano partnered with Tethon3D to develop a high-temperature, rigid electro-static dissipative (ESD) material resin for quick-turn soldering processes. The resin can be processed on a variety of vat photopolymerization systems, including stereolithography, digital light processing and liquid crystal display.

The company says the vat photopolymerization process enables quick-turn part fabrication with ultrahigh accuracy, nano-uniform ESD and exceptional surface finish, while taking advantage of custom 3D-printable design freedom.

This can help the electronics industry be more agile when handling bespoke customer requests by using additive manufacturing (AM) to fabricate ESD parts to support the reflow process. Mechnano uses AM to help electronic manufacturing service (EMS) providers reduce cycle time, increase throughput and ensure nano-uniform ESD protection.

The new material offers more production agility which is essential for customer-specific applications that require a variety of nonstandard components for low-volume production runs. Customers often request custom carriers/pallets to hold printed wiring assemblies during the reflow process. These carriers must protect today’s micro-electronic components from electrostatic discharge and withstand multiple cycles of a high-temperature wave soldering process (245°C).

Using traditional manufacturing technologies for fabrication of these components can slow down production and increase costs, while using the traditional carbon fiber-filled materials in these components does not protect today’s electronics. The challenge is quickly fabricating custom nano-uniform ESD components that would withstand numerous thermal cycles. The newly developed material can address those issues.
