Accelerating PCB protection at scale
Featured Product from ELANTAS North America LLC
From zero to cured — In runway time
Airlines and airports are not the only providers that value high levels of throughput and highly repeatable scheduling. This is a challenge also faced by all manufacturers that develop, design or deliver electronic circuit boards. Electronic circuit boards are the centerpiece of countless applications — from mobile, hand-held devices to automotive electronics, from household appliances to heavy industrial machinery. Conformal coatings provide effective protection against various environmental conditions such as humidity, dust, vibration and thermal stress. They form a dense and insulating protective layer over the contours of the PCB, reliably protecting sensitive components without impairing their function. As PCB designs become more compact with increasing component density and ever-expanding customer expectations, the reliance on conformal coatings continues to grow for protecting powerful electronics.
Bectron PT 4700 N, from ELANTAS, offers powerful protection as a solvent-free, light-curing conformal coating for electronic circuit boards that does not require an oven cure in the production process. Unlike conventional coating processes using solvent-based varnishes, with oven curing times of up to 20 minutes, ELANTAS Bectron PT 4700 N cures at room temperature in just 5 to 10 seconds under broadband UV light or in 10 to 20 seconds using an LED curing device (365 nm). This ultra rapid light-curing allows production to be completed in not only record time, but in runway time. In addition to this rapid curing processing, the Bectron PT 4700 N has a moisture driven secondary cure process. Allowing for cure completion of shadow areas on products in staging at room temperature versus in ovens or at the time of processing. This curing profile makes the Bectron PT 4700 N ideal for large scale production when every second counts.
