TRESKY soldering yana amfani da formic acid tururin tare da nitrogen (HCOOH + N2), wanda ke ba da fa'idodi a cikin optoelectronics da haɗakar photonics da fasahar haɗin kai. Formic acid yana rage oxides cikin aminci kuma yana kawar da kwarara gaba ɗaya. Amfani da formic acid kuma yana tabbatar da kyakkyawan danshi a saman, yana ƙirƙirar yanayi masu dacewa don hanyoyin walda masu rikitarwa. Ana amfani da wannan module don soldering eutectic da thermocompression walda, misali tare da indium. Duk hanyoyin haɗin suna amfani da nitrogen-enriched formic acid (HCOOH) ta amfani da abin da ake kira bubbler. Ana shigar da cakuda nitrogen tururin da formic acid cikin ɗakin magani ta hanyar da aka sarrafa kuma ana cire su.
