I-TRESKY soldering isebenzisa i-formic acid vapor ngokuhlanganiswa ne-nitrogen (HCOOH + N2), okunikela iinzuzo ku-optoelectronics kanye ne-photonics assembly kanye nobuchwepheshe bokuhlanganisa. I-formic acid yehlisa ama-oxide ngokuthembekileko begodu iqeda ngokupheleleko ukugeleza. Ukusetjenziswa kwe-formic acid godu kuqinisekisa ukuthamba okuhle kwephasi, okwenza ubujamo obufaneleko bokuwelda okuhlukahlukeneko. Imojuli le isetjenziselwa ukuwelda kwe-eutectic kanye nokuwelda ngokugandeleleka komtjhiso, ngokwesibonelo nge-indium. Zoke iinkambo zokuhlanganisa zisebenzisa i-nitrogen-enriched formic acid (HCOOH) kusetjenziswa lokho okubizwa nge-bubbler. Umxube we-nitrogen vapor ne-formic acid ufakwa ngaphakathi kwegumbi lokuhlanza ngendlela elawulwako bese uyakhishwa.
