Dymax launches 9310 adhesive for PCB reinforcement

Dymax has introduced 9310, a light-curing adhesive designed to reinforce fine-pitch, leadless components on printed circuit boards for advanced electronics and AI hardware. The material is built to speed assembly, survive reflow, and improve reliability in demanding manufacturing environments.

Why it matters: - Dymax 9310 targets a core reliability problem in advanced electronics: keeping fine-pitch, leadless components attached and stable on printed circuit boards. - The adhesive is designed for AI hardware and other complex electronics that face thermal stress, reflow cycles, and tight assembly tolerances. - Faster reinforcement can reduce reliance on traditional underfill and simplify manufacturing.

What happened: - Dymax launched 9310 adhesive for high-reliability PCB reinforcement. - The new material cures in seconds with light. - A secondary heat cure completes polymerization in shadowed areas. - The adhesive is intended to reinforce fine-pitch, leadless components on printed circuit boards.

The details: - Dymax says 9310 maintains adhesion through high-temperature reflow. - The formulation is built to flex under strain and absorb movement caused by thermal expansion. - The adhesive is engineered with 145% elongation and controlled modulus to help maintain bond integrity over time. - The material is designed to reduce stress on solder joints and components. - Its high viscosity and thixotropic profile support precise edge bonding without unwanted flow. - The adhesive is reworkable at relatively low temperatures. - Doug Katze, Senior Electronics Business Development Manager for Dymax, said 9310 makes reinforcement easier and more consistent without the added steps and complexity of underfill.

Between the lines: - Dymax is positioning 9310 as a process simplifier, not just a materials upgrade. - The combination of light cure, secondary heat cure, and reworkability suggests a focus on manufacturing speed and repair flexibility. - The product also fits a broader push for materials that can handle dense, high-heat electronics assemblies.

What's next: - Dymax is likely aiming for adoption in electronics manufacturing lines that need faster bonding and better thermal reliability. - The company’s broader materials and curing portfolio suggests 9310 will be paired with its dispensing equipment and UV/LED systems in production settings. - Demand will likely come first from advanced electronics, AI hardware, aerospace and defense, medical device, and consumer and automotive electronics markets.

The bottom line: - Dymax is betting that a fast-curing, reworkable adhesive with strong thermal performance can replace more complex underfill steps in high-reliability PCB assembly.
