JELK series
This specialized stripper is capable of removing stubborn resists and dry film resists remaining after ion implantation—materials that are typically difficult to strip using conventional amine-based solutions. Free of hydroxylamine and NMP, this product offers a safer, more environmentally friendly alternative without compromising performance.
