TRESKY soldering neekozesa omuyaga gwa formic acid omu kugaita na nitrogen (HCOOH + N2), ekirikuha oburungi omu kuteerana n’okuteerana eby’amaisho n’eby’amashanyarazi. Formic acid neekyendeeza omu muringo ogurikwesigwa kandi neemaraho kimwe okusheeshasheesha. Okukozesa formic acid nakyo nikihamya ngu aha itaka hariho amaizi marungi, ekirikureetaho embeera nungi z’okukora emirimo y’okushemeza egumire. Omuringo ogu nigukoresibwa omu kuteera eutectic n’okuteera thermocompression, eky’okureeberaho na indium. Emiringo yoona ey’okuteerana neekoresa ebiriisa ebirimu nitrogen (HCOOH) barikukoresa eki barikweta bubbler. Omutaano gw’omuyaga gwa nitrogen na formic acid nigutaaha omu kishengye ky’okujanjabiramu omu muringo ogurikutegyekwa kandi gushohozibwa.
