FIELD: electric engineering. ^ SUBSTANCE: in method for manufacturing of printed circuit boards, printed circuit boards are produced from glass-cloth laminate with transition holes, besides prior to chemical activation, glass-cloth laminate stock with technological and transition holes is heated at the temperature of 60-120C and pressure of not more than 760 mm of mercury column and is placed into organic solvent with high boiling temperature, which is not dissolved in water. ^ EFFECT: improved reliability and prolonged service life of printed circuit boards due to removal of water and salts from glass-cloth laminate base. |
