INVERTER PCB COATING APPLICATION
CUSTOMER APPLICATION: A global producer of inverters was looking to find an alternative to their solvent-based conformal coating process. They needed a new process that would be effective and efficient and could be used in multiple locations for 12 different types of inverter PCBs. The company’s ultimate goal was to find an alternative that could help them increase productivity within their existing manufacturing space to meet a 30% demand increase.
PROCESS COMPARISION
Solvent-Based Conformal Coatings
Dymax Dual-Cure Conformal Coatings
Immediate handling
Needs time for the solvent to evaporate
Tack-free immediately after UV light cure
Odor
Strong odor from solvents
Low odor for a safer working environment
Thickness to achieve throughput and cost targets
25 um max, dry thickness, did not meet the existing electrical requirement
