Abstract

A screen printing apparatus of the invention comprises: a supporting device supporting a circuit substrate from below; a clamp, from both sides, holding the side surface of the circuit substrate supported by the supporting device; a circuit substrate pressing device for pressing the circuit substrate from above, which is supported on the supporting device and maintaining the circuit substrate in a warp and then straightened state along an up-and-down direction. The circuit substrate pressing device holds the circuit substrate to move the same along a holding direction of the clamp. According to the invention, via the circuit substrate pressing device pressing the circuit substrate, a warp of the circuit substrate can be straightened and the circuit substrate can be maintained in this state.

Description

technical field

[0001] The present invention relates to a screen printing device for coating a paste such as cream solder on a circuit board. Background technique

[0002] In conventional screen printing devices, the squeegee moves (rotates) on the mask with the circuit board and the mask set on the printing table generally overlapped, and the creamy solder supplied to the mask, conductive Paste such as paste is printed (applied) on a predetermined position on the circuit board through openings (mask openings) formed in the mask.

[0003] The printing table of the above screen printing device includes, from below, a carrier device that supports the circuit board that is carried in substantially horizontally by a conveyor belt; A pair of clamps that overlap the matte. As a result, the above-mentioned circuit board is warped in the vertical direction as a whole, and if the circuit board in the warped state is clamped by the above-mentioned jig, an unnecessary gap will be gen...
