Patent ID: 6868780

Claim:
A screen printing method for printing paste on a work via pattern holes formed on a mask plate, comprising: a mask attachment step in which said work is brought into contact with the a lower surface of said mask plate; a squeegeeing step in which a squeegee is moved on the mask plate in the mask attachment state thereby to filling paste into said pattern holes; and a plate separating step in which the work is separated from the mask plate stepwise by a plate separating operation of repeating plural times an acceleration and deceleration pattern in which a moving speed at which said work is moved in the direction where the work separates from the mask plate is accelerated up to an upper limit speed and thereafter is decelerated up to a lower limit speed, wherein an initial upper limit speed representing said upper limit speed in start of said plate separating operation is set higher than succeeding upper limit speeds representing the upper limit speeds from the middle of the plate separating operation on, wherein in said plate separating operation, a plurality of said acceleration and deceleration patterns are set so that said succeeding upper limit speed are decelerated gradually.
