摘要:
It is possible to obtain a screen printing method that may assure excellent printing qualities since the screen printing method of the present invention includes: (A) sliding a squeegee head with paste stored in the squeegee head on a mask plate, while the past is pressurized, and printing the paste on a substrate through pattern holes of the mask plate, (B) at least one step of (b) separating the squeegee head with the paste stored therein from the mask plate, and (e) sliding the squeegee head on the mask plate for a pre-squeezing purpose before the step (A). The step of separating the squeegee head from the mask plate includes the steps of (1) discontinuing the pressure application to the paste stored in the squeegee head, (2) horizontally moving the squeegee head by a predetermined distance while the bottom end portion of the squeegee head is abutted on the mask plate in a state of the pressure application being discontinued, and (3) moving the squeegee head upward off from the mask plate. 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.

摘要:
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.
摘要:
A screen-printing apparatus for printing creamy solder paste on a substrate by attaching a screen mask to the substrate. A laser-measuring device mounted in the apparatus measures the top surface of the screen mask at a printing position and the top of the substrate at a substrate-measurement position by three-dimensional measurement, and detects a shape of the substrate or the screen mask, and determines whether or not they are acceptable. After screen printing is completed, the substrate and the screen mask undergo a printing inspection where their shapes are inspected. This provides not only inspection data of the printing results but also data for identifying the causes of print failures. As a result, the screen-printing apparatus, which has high-printing accuracy and can prevent printing failures from occurring, is provided.

An object of the invention to provide a screen printing machine allows, during maintenance work for one printing device, the other printing device to continue its screen printing work, and a method for controlling an inside temperature of a screen printing machine. A space surrounded by a base (12) and a cover member (11) is divided into two portions by a partition member (14), and two printing devices (13) are accommodated in two working compartments (15), respectively, which are defined by the base (12), the cover member (11) and the partition member (14), whereby temperature-controlled air is blown into each of the working compartments (15) via an air pipe (71) which branches into two air vents (72) opened to the respective working compartments (15).

An object of the invention is to provide an electronic component mounting device and a work method of the electronic component mounting device, capable of ensuring safety of an operator who accesses a work line through a door portion, and avoiding reduction of workability. A space defined by a base (11) and a cover member (14) is partitioned by a partition member (15) to define a plurality of work line storing spaces (SP1). A plurality of work lines (12) are stored in the respective work line storing spaces (SP1) individually. When any of a plurality of door portions (14a) provided in the cover member (14) so as to allow an access to an inside of the respective work line storing spaces (SP1) is opened, an operation of a work line (12) stored in a work line storing space (SP1) accessible through the opened door portion (14a) is stopped.

摘要:
A screen printing apparatus is designed so that cream solder 17 disposed on a mask plate 12 can be preserved at a certain appropriate temperature by the limited use of blown air. An air nozzle unit 20 is provided above the mask plate 12 at a place on the side edge running in parallel with the moving direction of a squeegee 16. The temperature-conditioning air is blown sidewise from the air nozzle unit 20 towards the cream solder 17 during the operation of printing the cream solder 17 on the surface of a substrate through the mask plate 12 disposed in contact therewith.
摘要:
To provide a printing inspection apparatus and a printing inspection method enabling an optimal inspection mode in which a balance is kept between the improvement of production efficiency and the securing of a printing accuracy.In a printing inspection for inspecting a printing state of cream solder on a substrate after screen printing, inspection data is generated by dividing unit shape and position data, indicating the shapes and the positions of element solder print portions to be printed on electrodes provided on a circuit forming surface of the substrate to be used to bond electronic components, into data groups according to a grouping condition chosen in response to an inspection mode. A go/no-go judgment at the time of inspection is made per data group, and a judgment result is displayed for each data group. It is thus possible to choose an optimal inspection mode flexibly in response to the characteristics of a substrate as the subject to be inspected.
