Snap cure conductive adhesive are mostly employed in high volume production processes, due to dispensing ease and rapid adhesion at relatively low temperatures and high strength on a variety of substrates in less than one minute they also need to provide low shrinkage after curing and low stress characteristics.

Solution

The EMS 561-400 series is used in modified ribbon stringers as the adhesive is more stress absorbing than solder to withstand the rigors of thermal cycling and processes at lower temperatures than solder. EMS 561-400 series conductive adhesives are claimed to be 60% less expensive than pure silver-filled conductive adhesives.

Applications

Snap curing conductive adhesive for crystalline silicon and heterojunction solar modules.

Platform

The EMS 561-400 series is designed to be used in modified ribbon stringers. The material will snap cure and fixture ribbons in seconds at 150°C with enough strength to withstand module manufacturing processes until the adhesive cure is completed during the encapsulant lamination process. EMS 561-400 series conductive adhesives can be dispensed by time-pressure, auger or jetting.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 7-8 October 2025 is our third PV CellTech conference dedicated to the U.S. manufacturing sector. The events in 2023 and 2024 were a sell out success and 2025 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
