Definitions
- the present invention relates to a screen extending frame in which a screen for screen printing in a sheet shape or a mesh shape is extended and is mounted on a screen extending jig for adjusting tension of the screen in regard to manufacturing of printed circuit boards.
- a printed circuit board in the subtractive process that is generally used in electric/electronic devices is configured to be formed with a conductive pattern by removing unnecessary portions of copper foil stuck to an insulating substrate, and active and passive elements are fixed to the conductive pattern by means of soldering, or the like.
- a screen board which is a mesh-like sheet woven with a metal or a resin or a sheet made of a metal or a resin, is used by forming holes of image thereon and by extending the sheet in a frame with uniform tension, not making crinkles.
- a metal mask where through holes are formed on a metal thin plate made of stainless steel or the like is extended in a screen extending frame with tension, ink is transferred onto the insulating substrate via the through holes using a squeegee, and thereby, a conductive pattern or a solder pattern is formed thereon.
- a planar shape is ideal for the object to be printed, but there may be warping or waviness thereon in some cases, and a material with flexibility is selected for the squeegee in order to keep the screen board in tight contact with the printed object, and the extending tension of the screen is not so tensed.
- the screen is required to be as strongly extended as possible, a rigid and sturdy screen frame is prepared, the sheet is intensively pulled from four directions, and extended using a stretching property of the sheet material and using a repulsive force thereof.
- the sheet can be extended since the mesh does not have a high stretching property but has a little.
- the sheet can be extended by connecting the outer circumference of the centered metal sheet to a resin sheet having the stretching property.
- the screen is used as attached to the screen extending frame. If there has slack, the location of the printed pattern is deviated or the pattern is warped when the screen is rubbed by the squeegee. In order to prevent such a situation, it is necessary to always give a certain degree of tension to the screen by exerting a tensile force thereto when printing is performed.
- a tension fixed frame of which the size is fixed so as to maintain the tensile force of the screen constant there are a tension fixed frame of which the size is fixed so as to maintain the tensile force of the screen constant, and a tension variable frame of which the size varies so as to be able to change the tensile force of the screen. Since both frames are required to have strength that gives a tensile force to the screen, the frames have to be robust and large.
- the tension variable frame of which the size varies includes a variable mechanism, and accordingly, the frame costs higher.
- the screen needs to be separated from the circuit board to be printed before and after printing, and to be brought into tight contact with the circuit board when printing is performed using a squeegee. For this reason, the screen is required to have the stretching property.
- the metal mask does not have the stretching property, it is, in general, stuck to a mesh made of polyester strings, stainless steel strings, or the like and is used as a screen. There may be a case where a metal mask is used as it is, and in that case, any extending and reducing mechanism is provided in the mounting portion of the metal mask or in the screen extending frame.
- a screen using a mesh is attached to the screen extending frame mostly by using an adhesive agent, and such the screen is kept attached to the screen extending frame so long as the screen is necessary. For this reason, when being not in use, the heavy and bulky screen has to be stored or transported.
- a screen extending frame in a configuration where the end part of the screen using a mesh is attached thereto by means of winding, clamping, or the like.
- the screen extending frame it is possible to remove the screen from the screen extending frame for storage or transportation when the screen is not in use, but it is not easy to store or transport the screen without damaging the printing patterns that are precisely formed thereon as the screen is thin.
- Patent Application No. 2002-556010 (refer to Publication No. WO2002/055304) a device for screen printing in which a screen extending frame is divided into a screen extending jig having a tensile force adjusting mechanism and a screen extending frame in a simple structure without the tensile force adjusting mechanism, which is provided with an engagement mechanism to connect the jig and the frame with each other, and thereby, the screen is attached to the screen extending frame.
- the screen printing device is described referring to FIG. 1 .
- the reference numeral 1 is the screen extending jig, and the screen extending frame 2 having engagement grooves 4 is mounted on the screen extending jig 1 .
- a screen 3 is attached, which is a sheet that is a metal plate or a resin plate with conductive patterns formed by through holes, or is a mesh stuck a sheet with conductive patterns formed by through holes, not shown in the drawing, thereto.
- the screen extending frame 2 is constituted by joining four plate-shaped, or rectangular tube-shaped frame members together by means of welding, or the like.
- each frame member constituting the screen extending frame
- the length in the longitudinal direction of each frame member represents the “length”
- the length from the outside to the inside thereof represents the “width”
- the length between a face to which the sheet is attached and a face to which the sheet is not attached represents the “thickness”.
- FIGS. 1 (B) and (C) illustrate mounting the screen extending frame 2 on the screen extending jig 1 .
- FIG. 1 (B) shows the state of the screen extending frame 2 before being mounted on the screen extending jig 1
- FIG. 1 (C) shows the state of the screen extending frame 2 being mounted on the screen extending jig 1 .
- the engagement grooves 4 are formed on the mounting sides of the screen extending frame 2 along the longitudinal direction of the screen extending jig, and engagement elements 5 are formed on the mounting sides of the screen extending jig 1 along the longitudinal direction of the screen extending jig.
- the tensile force to the screen 3 is adjusted by extending or reducing the screen extending jig 1 in the arrow directions shown in the drawing where the engagement elements 5 are kept engaged with the engagement grooves 4 .
- Conductive patterns are formed using the screen by transferring ink with a squeegee not shown in the drawing via through holes.
- the screen is attached to the screen extending frame 2 by fixing means such as an adhesive agent, that is mounted on the screen extending jig 1 , and the tensile force is exerted thereon by the screen extending jig 1 .
- fixing means such as an adhesive agent
- slack or the like occurs which may cause the screen deformation. It is, therefore, desirable for the screen to have a certain degree of tension even being attached only to the screen extending frame 2 .

Description
- The present invention relates to a screen extending frame in which a screen for screen printing in a sheet shape or a mesh shape is extended and is mounted on a screen extending jig for adjusting tension of the screen in regard to manufacturing of printed circuit boards.
- A printed circuit board in the subtractive process that is generally used in electric/electronic devices is configured to be formed with a conductive pattern by removing unnecessary portions of copper foil stuck to an insulating substrate, and active and passive elements are fixed to the conductive pattern by means of soldering, or the like.
- In the subtractive process, after holes are made on an insulating substrate, such as a glass epoxy plate, to which copper foil is stuck, unnecessary portions of the copper foil is removed by printing and etching, and then a conductive pattern is formed. When soldering is performed by a reflow method, solder cream is printed further on necessary portions.
- In screen printing, a screen board, which is a mesh-like sheet woven with a metal or a resin or a sheet made of a metal or a resin, is used by forming holes of image thereon and by extending the sheet in a frame with uniform tension, not making crinkles.
- With regard to a printed pattern, a metal mask where through holes are formed on a metal thin plate made of stainless steel or the like is extended in a screen extending frame with tension, ink is transferred onto the insulating substrate via the through holes using a squeegee, and thereby, a conductive pattern or a solder pattern is formed thereon.
- At this moment, if the screen board does not come into tight contact with the object to be printed, the ink runs over from a gap causing bleeding, which results in inaccurate printing.
- A planar shape is ideal for the object to be printed, but there may be warping or waviness thereon in some cases, and a material with flexibility is selected for the squeegee in order to keep the screen board in tight contact with the printed object, and the extending tension of the screen is not so tensed.
- However, since the screen is required to be as strongly extended as possible, a rigid and sturdy screen frame is prepared, the sheet is intensively pulled from four directions, and extended using a stretching property of the sheet material and using a repulsive force thereof.
- When a metal mesh is used, it can be extended since the mesh does not have a high stretching property but has a little. When a metal sheet with no stretching property is used, the sheet can be extended by connecting the outer circumference of the centered metal sheet to a resin sheet having the stretching property.
- The screen is used as attached to the screen extending frame. If there has slack, the location of the printed pattern is deviated or the pattern is warped when the screen is rubbed by the squeegee. In order to prevent such a situation, it is necessary to always give a certain degree of tension to the screen by exerting a tensile force thereto when printing is performed.
- For a screen extending frame, there are a tension fixed frame of which the size is fixed so as to maintain the tensile force of the screen constant, and a tension variable frame of which the size varies so as to be able to change the tensile force of the screen. Since both frames are required to have strength that gives a tensile force to the screen, the frames have to be robust and large. In addition, the tension variable frame of which the size varies includes a variable mechanism, and accordingly, the frame costs higher.
- The screen needs to be separated from the circuit board to be printed before and after printing, and to be brought into tight contact with the circuit board when printing is performed using a squeegee. For this reason, the screen is required to have the stretching property. However, since the metal mask does not have the stretching property, it is, in general, stuck to a mesh made of polyester strings, stainless steel strings, or the like and is used as a screen. There may be a case where a metal mask is used as it is, and in that case, any extending and reducing mechanism is provided in the mounting portion of the metal mask or in the screen extending frame.
- A screen using a mesh is attached to the screen extending frame mostly by using an adhesive agent, and such the screen is kept attached to the screen extending frame so long as the screen is necessary. For this reason, when being not in use, the heavy and bulky screen has to be stored or transported.
- There is a screen extending frame in a configuration where the end part of the screen using a mesh is attached thereto by means of winding, clamping, or the like. In a case of such the screen extending frame, it is possible to remove the screen from the screen extending frame for storage or transportation when the screen is not in use, but it is not easy to store or transport the screen without damaging the printing patterns that are precisely formed thereon as the screen is thin.
- Taking the circumstances into consideration, the present inventor has proposed in Patent Application No. 2002-556010 (refer to Publication No. WO2002/055304) a device for screen printing in which a screen extending frame is divided into a screen extending jig having a tensile force adjusting mechanism and a screen extending frame in a simple structure without the tensile force adjusting mechanism, which is provided with an engagement mechanism to connect the jig and the frame with each other, and thereby, the screen is attached to the screen extending frame.
- The screen printing device is described referring to
FIG. 1 . - In
FIG. 1 (A), thereference numeral 1 is the screen extending jig, and thescreen extending frame 2 havingengagement grooves 4 is mounted on thescreen extending jig 1. To thescreen extending frame 2, ascreen 3 is attached, which is a sheet that is a metal plate or a resin plate with conductive patterns formed by through holes, or is a mesh stuck a sheet with conductive patterns formed by through holes, not shown in the drawing, thereto. By extending and reducing thescreen extending jig 1, an appropriate tensile force is exerted on thescreen 3. - The
screen extending frame 2 is constituted by joining four plate-shaped, or rectangular tube-shaped frame members together by means of welding, or the like. - In description hereinafter, on frame members constituting the screen extending frame, the length in the longitudinal direction of each frame member represents the “length”, the length from the outside to the inside thereof represents the “width”, and the length between a face to which the sheet is attached and a face to which the sheet is not attached represents the “thickness”.
-
FIGS. 1 (B) and (C) illustrate mounting thescreen extending frame 2 on thescreen extending jig 1.FIG. 1 (B) shows the state of thescreen extending frame 2 before being mounted on thescreen extending jig 1, andFIG. 1 (C) shows the state of thescreen extending frame 2 being mounted on thescreen extending jig 1. - The
engagement grooves 4 are formed on the mounting sides of thescreen extending frame 2 along the longitudinal direction of the screen extending jig, andengagement elements 5 are formed on the mounting sides of thescreen extending jig 1 along the longitudinal direction of the screen extending jig. - The tensile force to the
screen 3 is adjusted by extending or reducing thescreen extending jig 1 in the arrow directions shown in the drawing where theengagement elements 5 are kept engaged with theengagement grooves 4. - Conductive patterns are formed using the screen by transferring ink with a squeegee not shown in the drawing via through holes.
- When the screen is not in use and to be stored, it is most ideal to store the
screen extending frame 2 being mounted on thescreen extending jig 1, but since thescreen extending jig 1 having an extending and reducing mechanism is not only expensive but also bulky, storage or transportation of thescreen extending frame 2 attached with the screen being mounted on thescreen extending jig 1 is not efficient. - The screen is attached to the
screen extending frame 2 by fixing means such as an adhesive agent, that is mounted on thescreen extending jig 1, and the tensile force is exerted thereon by thescreen extending jig 1. When not being mounted on thescreen extending jig 1, slack or the like occurs which may cause the screen deformation. It is, therefore, desirable for the screen to have a certain degree of tension even being attached only to thescreen extending frame 2. - A screen printing device using a screen extending frame, in which the screen is attached to a screen extending frame, the screen extending frame is mounted on the screen extending jig, and the tension of the screen is adjusted by changing the size of the screen extending jig, is disclosed in Japanese Patent Laid-Open Publication Nos. 2006-212955, 2006-44180 and 2008-1010 by the present inventor, in addition to the publication WO2002/055304.

FIGS. 23 to 25 , a hollow-bodied screen extending frame gains flexibility at the joint of frame members by cut grooves formed on the joint. - While stress is put on the frame and a screen is attached thereto using a repulsive force against the stress, the sides of the frame bend, and the repulsive power is generated.
- The repulsive force is generated strong in the center of the sides of the frame, and weaker as close to the vicinity of couplings of the frame.
- The situation is similar also in other configurations, and crinkles may occur around the corners if there is no countermeasure.
- In Embodiment 18 shown in
FIG. 23 , in each of square-shaped hollow frame members one notch is formed on both sides in the vicinity of the joint of frame members in the width direction. - A bendable flexible part is configured with these notches.

In addition, since the lower half part thereof does not have a notch, the lower half part constitutes a frame with strength.
- In this case, it is very effective to make the thickness in the vertical portion of the upper half part of the two-tier hollow body thin and the thickness in the vertical portion of the lower half part of the two-tier hollow body thick.
- A notch or a through hole is formed on a wall face in the thickness direction of the frame side in the upper half part of the hollow body in the thickness direction in order to lower the strength of the frame side and to make deformation easy.
- By doing this, deformation becomes easy by lowering the strength of the wall face of the upper frame side in the thickness direction, and thus, it is possible to apply a tensile force also in the vicinity of the joint, and overall uniform extending is possible.
- Since a notch or a through hole is not formed in the lower half part of the frame side, the lower half part constitutes the frame with strength, that has the same effect as making the thickness in the vertical portion of the upper half part of the two-tier hollow body thin and the thickness in the vertical portion of the lower half part of the two-tier hollow body thick.
