mth-90 used solder with a high lead content. Therefore, for a long time of non-use, the balls on the legs of the solder oxidize and form a rather large film of oxide that prevents the metal itself from melting. To do this, you need to remove the plaque to a shiny with anything, a file or a knife. And after that, everything is soldered quite easily. суббота, 29 апреля 2023 г. в 19:31:58 UTC+3, Jasper nagle:
