Immersing the encapsulated component in this material will also soften the encapsulant the same as Methylene Chloride and of course, it will also attack and destroy any embedded epoxy devices. There has been some success reported in using the commonly available paint stripper sold under the trade name Circa 1867. Unfortunately, since printed circuit boards and many electronic components are also encapsulated with epoxy, they will also be damaged or destroyed by this solvent. Methylene Chloride will cause the encapsulant to swell and become soft for removal. The user must take all precautions to prevent contact with skin and not to inhale the vapours while using this product. We define the associated equivalence relation as s t. This solvent is hard to obtain as it has been declared a carcinogen. We also developed an automated tool (Polytool) for termination analysis based. Sdim: to toggle between poly Area, length and segment length. The other method is to immerse the encapsulated component in Methylene Chloride. Keyboard Command: Adim: to add dimensions to existing polyline ( Area, Length or perimeter) Cpoly: to convert Arc, line to polyline and join polylines. Ensure to wear an appropriate face mask and good ventilation while removing the encapsulant when using this method. Epoxies and polyurethanes will smoke and give off odours when heated to high temperatures. This method is more convenient for recovering heavier solid components than reclaiming delicate electronic circuits. At this point the encapsulant will be soft enough to cut or penetrate with a chisel like device and break it away from the embedded component. The easiest method to remove epoxy or polyurethane is to heat it above its glass transition (softening point) temperature. In certain instances however, where the embedded component is reusable, such as an encapsulated conductor, it is worth while to remove the encapsulant and reclaim the embedded part. At best it is difficult to remove cured material without damaging the encapsulated components.
