PROCESS OF CLEARING OF HOLES OF PRINTED-CIRCUIT BOARDS Russian patent published in 1997 - IPC

Abstract RU 2074537 C1

FIELD: radioelectronics. SUBSTANCE: hydrocavitation generator and printed- circuit board are placed into liquid medium and jet of cavitating liquid is formed perpendicular to surface of this board along holes in printed-circuit board. Clearing of holes from microinclusions takes place thanks to passage of cavitating flow through holes. Jet flow action is carried out under pressure difference 0.6-10.0 MPa. EFFECT: improved clearing efficiency of process. 2 cl, 1 dwg
