Movable clawsare formed in clampersholding a substrateso that the movable claws can be selectively moved to a position where they have projected above the substrate, and to a position where they have retreated from above the substrate. Thereby, the safety of operation is ensured by causing the movable clawsto retreat during maintenance. Moreover, printing with high precision can be performed in a state where the surface of the substrateand the rear face of the maskare brought into surface contact with each other without any clearance by causing the movable clawsto retreat.

In a screen printing apparatus which prints solder cream on a substrate by a closed type squeeze head, in print spacethat houses the solder creampressurized in a paste storing part and brings the solder creaminto contact with a surface of a mask plate, a hollow heat regulating memberprovided in a horizontal direction orthogonal to a squeezing direction is caused to pass, and a heat regulating medium is circulated inside the heat regulating memberby a heat regulator, whereby the solder creamin the print spacecan be always kept at an appropriate temperature and at an appropriate viscosity, so that print quality can be secured.

Screen printing apparatus

A cream solder cartridge used in a screen printing apparatus which prints cream solder on a board through pattern holes by sliding, on a mask plate, a closed squeegee that is stored with cream solder inside is composed of a long and narrow concave portion made of a flexible film-like material, a brim portion projecting from the outer periphery of the concave portion, and a film-like cover sheet that is stuck to the brim portion and thereby closes the opening of the concave portion. This configuration makes it possible to supply paste at a low cost and to perform a viscosity adjustment easily by externally stirring the paste accommodated inside.

A screen printing apparatus and method in that in the print parameter setting process for setting print parameters including a squeegee movement speed, a printing pressure, and plate release conditions, a squeegee movement speed at which the squeegee is to be moved is set at the first step, then a printing pressure for realizing a desired cream solder charging state is set at the second step, and then plate release conditions for realizing a desired cream solder transfer state is set at the third step. Therefore, the print parameter setting process can be performed according to an efficient processing procedure and trial-and-error-based backward work can be avoided. Print parameters can be set quickly and properly for a wide range of solder types.

Screen printing apparatus and screen printing method

A screen printing apparatus prints cream solder through a pattern hole of a mask plate, to which a substrate is brought into contact, by sliding a squeegee head. A three dimensional detector, such as a laser, is used to determine the extent to which the pattern hole is filled with the cream solder. Based on the determination result, the printing operation is modified, with respect to the positioning of the mask plate and substrate, to maintain the printing quality.

Screen printing apparatus and method of the same

In a screen printing method of bringing a mask plate into contact with a substrate to print solder cream through a pattern hole on the substrate, a plate separating operation of separating the substrate from the mask plate after a squeegeeing step in which the solder cream is filled into the pattern hole comprises an operation pattern in which acceleration and deceleration pattern in which a descending speed is accelerated up to an upper limit speed and thereafter decelerated up to a lower limit speed is repeated plural times. Further, an initial upper limit speed in start of the plate separating operation is set higher than the succeeding upper limit speeds, whereby viscosity of the solder cream into the pattern hole in start of the plate separating operation is lowered, and the mask plate can be separated with a high accuracy throughout the entire range of the substrate.

Screen printing method including variable speed plate separating operation

In a screen-printing apparatus for printing creamy solder paste on a substrate by attaching a screen mask to the substrate, a predetermined measuring position of the mechanisms in the screen-printing apparatus is measured three-dimensionally by a three-dimensional measuring device. Based on the measured result, a predetermined measuring point on an object to be measured is determined on a position relative to the origin of the mechanical coordinate system in the screen-printing apparatus, and the origin position on a control program can be set. As a result, machine adjusting operation and teaching operation in the screen-printing apparatus can be simplified with high accuracy.

Apparatus and method of screen printing

Cream solder stored in a squeegee head is pressurized by a pressurizing plate, and the squeegee head is slid on a mask plate, so that the cream solder is printed onto a substrate via pattern apertures. This is done by a screen printing apparatus, in which pressurized solder is accommodated, and the solder is brought into contact with a surface of the mask plate via an opening formed on a lower face of the cell. A rectifier is disposed in the cell for blocking the cream solder from flowing into a specific area just above the opening. This structure allows the solder to flow into the opening in a slant direction, and causes the solder to roll. This mechanism prevents the solder from being hardened due to staying stagnant just above the opening, and thus prevents defective printings.

In the step of pre-squeezing includes the steps of (1) pressurizing the paste stored in the squeegee head in a state of the squeegee head being abutted on the mask plate, and (2) horizontally moving the squeegee head while the bottom end portion of the squeegee head is abutted on the mask plate in a state of the paste being pressurized.
