Following the thermal bonding stage, this process completes the cross-linking polymer network of the ACF epoxy matrix. By ensuring complete chemical curing, the compressed conductive particles are permanently locked into position under constant tension, securing optimal contact resistance and mechanical peel strength against environmental degradation.
Maxen utilizes Multi-Zone Precision Thermal Convection Ovens alongside High-Intensity Narrow-Spectrum UV-LED Curing Tunnels. The environment is strictly regulated by Continuous Temperature & Humidity Data Loggers linked to a centralized SCADA system. Polymer cross-linking density is audited using Differential Scanning Calorimetry (DSC) testing equipment and Mecmesin Peel Strength Testers.
Depending on whether a thermal-setting or dual-cure (UV + thermal) epoxy resin chemistry is deployed, the curing duration ranges from 10 to 20 minutes inside continuous conveyor ovens.
To reduce thermal loading on the sensitive driver IC chips, Maxen is collaborating with premium resin manufacturers to test Low-Temperature Fast-Curing ACF materials (120°C activation). Our objective is to lower the oven processing time by 35% while increasing the joint's thermal stability. This guarantees flawless performance during rigorous environmental stress testing, including 1,000 hours of High-Temperature/High-Humidity exposure (85°C / 85% RH).
