Tšebeliso ea fr4 epoxy board ho sephethephethe

E mong le e mong oa rona o tla pepesehela litaba tsa maeto bophelong ba rona. Ho na le mefuta e mengata ea lipalangoang, tse tloaelehileng ke likoloi, lifofane, literene tse tsamaeang ka tlas’a lefatše le literene. Joale rea tseba hore kahong ea metro le literene, liboto tsa fr4 epoxy li bohlokoa haholo!

Kahoo, mokhoa oa ho sebelisa FR4 epoxy board ka tereneng kapa ka tereneng? Litlhoko tsa thepa tse sebelisoang tseleng e tsamaeang ka tlas’a lefatše li tlameha ho ba holimo haholo, joale fr4 e sebelisoa joang?

Ha re shebeng thepa e khethehileng ea FR-4 epoxy board.
