Description

JIG FOR CIRCUIT BOARD MODULE {JIG FOR CIRCUIT BOARD MODULE}

The present invention relates to a jig for a circuit board module, and more particularly, to a jig for a circuit board module implemented to be attached to prevent the flexible circuit board module from bending.

Recently, with the miniaturization of electronic equipment, circuit boards have been developed to facilitate the embedding even in more complex and narrow spaces. In addition, the circuit board has been used as a main board such as a mobile communication terminal due to the development of technology, and the circuit board itself is also used by embedding the chip directly.

In this case, the circuit board is manufactured by arranging a plurality of identical products on one sheet and then cutting and separating the same products. Hereinafter, for convenience of description, a sheet state in which a plurality of circuit boards is arranged is called a circuit board module.

On the other hand, in a circuit board module, a chip is often mounted as a component element on each circuit board. The circuit board module is mounted in a separate fixing jig to position the circuit board module. Subsequently, the circuit board module and the jig are put into the silk screen printing apparatus, the screen printing of the solder on the chip mounting part of each circuit board, the chip is mounted on the circuit board, and then the circuit board module and the jig are put into the baking apparatus and baked. As the printed solder is melted, the chip is soldered and fixed to each circuit board.

At this time, since the precision positioning device for positioning the chip in the circuit board module has a limited range for reading the position of the circuit board module, the position of the circuit board module before the circuit board module is inserted into the silk screen printing apparatus. To hold the first operation is required, the operation of holding the position of the circuit board module is performed by using a separate positioning jig. That is, the circuit board module is installed in the positioning jig to position the circuit board first. Subsequently, when the jig panel constituting the positioning jig and the circuit board module attached thereto are put together in the precision positioning device, the precision positioning device detects the reference points formed on both sides of the upper surface of the circuit board module to locate the circuit board module. Set the precision again. Then, the position of the circuit board module is precisely set again by the precision position adjusting device, and then the circuit board module is put into the silk screen printing apparatus to print the solder and continue to be performed later.

By the way, the circuit board module is not produced by only one standard, but is produced in various shapes and specifications according to the type of electronic products to use the circuit board, conventionally, in order to position the circuit board module of various specifications There is a problem in that the jig of the different standards for each of the specifications of the substrate module has to be produced, and furthermore, because different types of jig must be manufactured separately, it results in disadvantages in terms of economic efficiency.

Module boards, i.e. circuit board modules, are becoming thinner and thinner. In order to prevent bending of thin circuit board modules during the machining process, it is necessary to use transfer boards called carrier jigs in all companies. do.

At this time, in the case of a product having a large number of parts, a bending phenomenon occurs more easily during the production process. For example, a bending phenomenon occurs in a heat-cured part, causing cracks in parts and an open phenomenon (connection between circuits). Since the product cannot function properly, a carrier jig is required for each model to prevent this from happening.

Therefore, conventionally, in order to prevent the circuit board module produced in accordance with the trend of thinner thickness to bend during the machining process, there is a disadvantage in that each model must have a carrier jig of a different standard, furthermore, a carrier jig of a different standard It is a situation that results in a waste of cost by providing a mold for jig for manufacturing.

On the other hand, the background art described above is technical information possessed by the inventors for the derivation of the present invention or acquired in the derivation process of the present invention, and is not necessarily a publicly known technique disclosed to the general public before the application of the present invention. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

1 is a view showing a schematic configuration of a jig for a circuit board module according to an embodiment of the present invention.

Referring to FIG. 1, a jig 10 for a circuit board module according to an exemplary embodiment of the present invention includes a jig body 100, a substrate seating recess 200, and an adhesive line 300.

The jig body 100 is formed in the shape of a flat plate with each corner rounded, a substrate mounting groove 200 corresponding to the shape of the circuit board module 1 is formed on the upper side, one side of the substrate mounting groove 200 And the adhesive line 300 in the longitudinal direction on the other side is installed.

That is, the jig body 100 is a post-process such as a precision positioning device by attaching the circuit board module 1, which is made of a flexible material, seated in the board seating groove 200, as shown in FIG. It can prevent the warping.

The substrate seating recess 200 is formed on the jig body 100 so as to correspond to the shape of the circuit board 1 so that the circuit board module 1 may be seated.

That is, the substrate seating groove 200 may be formed on the top of each jig body 100 in a form corresponding to the shape of the circuit board module 1 so that the substrate seating groove 200 may be applied to various types of circuit board modules 1. .

The adhesion line 300 is installed in one direction and the other side of the substrate seating groove 200 in the longitudinal direction so that the circuit board module 1 can be temporarily attached to the board seating groove 200.

In one embodiment, an adhesive layer for temporarily attaching the upper surface circuit board module 1 of the adhesive line 300 may be provided, and the lower surface may be applied with an adhesive composition for attaching to the substrate seating groove 200. .

That is, the adhesive composition for temporarily attaching the circuit board module 1 and the adhesive composition for attaching to the circuit board module 1 are different kinds of compositions, hereinafter, the adhesive composition for attaching to the circuit board module 1. This will be described.

Here, the adhesive composition is an adhesive adhesive composition for attaching the adhesive line 300 to the substrate seating groove 200, 40 to 80 parts by weight of the thermoplastic resin, 5 to 40 parts by weight of the tackifier resin, 1 to 5 parts by weight rosin , 1 to 10 parts by weight of plasticizer, 1 to 10 parts by weight of filler and 0.1 to 1 part by weight of antioxidant.

The thermoplastic resin serves as a main component of the composition to control adhesion and cohesion. If the type includes a vinyl group or a hydroxyl group, the type is not particularly limited, and examples thereof include ethylene vinyl acetate copolymer, polyvinylacetate, polyvinyl alcohol, ethylene-acrylic acid copolymer and ethylene-methacrylic acid copolymer, and polyurethane. It may be composed of any one or more selected from the group consisting of.

The content of the thermoplastic resin is preferably 40 to 80 parts by weight based on the total composition. If the content is less than 40 parts by weight, the melt viscosity is high and the melt flow index is low, the workability is very poor, if the content is more than 80 parts by weight it is difficult to exert sufficient adhesive force to be applied directly to the fabric.

The tackifier resin is a low molecular weight resin, lowers the melt viscosity to improve workability, improves the initial wettability of adhesion and adhesion of the adhesive on the surface of the adherend, and enables control of the solidification time.

The tackifying resin is not particularly limited in kind, but is preferably a petroleum resin. More specifically, the tackifier resin may be composed of one or more selected from the group consisting of aliphatic hydrocarbon resins, alicyclic hydrocarbon resins, aromatic hydrocarbon resins, aromatic hydrocarbon-modified aliphatic hydrocarbon resins, and hydrogenated hydrocarbon resins.

The aliphatic hydrocarbon resins are commercial products such as Hikorez A-1100, Hikorez A-1100S, Hikorez C-1100, Hikorez R-1100, Hikorez R-1100S, and the like. In addition, alicyclic hydrocarbon resins include hydrocarbon resins containing dicyclopentadiene (DCPD) as monomers, and aromatic hydrocarbon resins are commercially available from Kolon Oil Co., Ltd. of Hikotack P-110S, Hikotack P-120, Hikotack P-120HS, Hikotack P-120S, Hikotack P-140, Hikotack P-140M, Hikotack P-150, Hikotack P-160, Hikotack P-90, Hikotack P-90S, Hirenol PL-1000, Hirenol PL-400. In addition, aromatic hydrocarbon-modified aliphatic hydrocarbon resins include Hikorez T-1080, Hikorez T-1100, etc. of Kolon Oils. Hydrogenated hydrocarbon resins can also be subdivided into hydrogenated aliphatic hydrocarbon resins, hydrogenated aromatic hydrocarbon resins, and the like, and commercially available from Kolon Oil, Sukorez D-300, Sukorez D-390, Sukorez SU-100, Sukorez SU-110, Sukorez SU-120, Sukorez SU-130 and Sukorez SU-90.

The tackifier resin is preferably a hydrocarbon resin having 4 to 10 carbon atoms in the monomer, and specifically, a C5 aliphatic resin, a C9 aromatic resin, a C5 / C9 aliphatic / aromatic copolymer resin, or the like may be used.

In addition, the tackifying resin of the present invention is more preferably characterized in that the hydrocarbon hydrocarbon resin containing dicyclopentadiene as a monomer, commercially available from Sukorez D-300, Sukorez D-390, Kolon Emulsifier (Korea), Sukorez SU-100, Sukorez SU-110, Sukorez SU-120, SukorezSU-130 and Sukorez SU-90.

On the other hand, the adhesive composition of the present invention, in order to minimize the irritation when applied to the operator's skin when applied to the lower side of the adhesive line 300, it is preferable to use a mixture of biodegradable hypoallergenic resin in the above-described various petroleum resin Do.

The biodegradable hypoallergenic resin may be prepared by melt-mixing a monomer of a polymer into a biodegradable polymer, and polylactic acid is preferably used as the biodegradable polymer.

The polylactic acid is a polyester synthesized by polycondensation of lactate or ring-opening polymerization of lactide, and has a medium physical property between polyamide and polyethylene terephthalate, and is mainly made of natural vegetable sugar components obtained from potatoes and corn. Biodegradability is high, but generally has high hardness, low elasticity, and poor durability.

The biodegradable polymer is melt-mixed with the same polymer monomer, wherein the biodegradable polymer is partially bonded with the monomer to cause chain breakage, thereby lowering the overall number average molecular weight. As the number average molecular weight falls, the physical properties that can be used as an adhesive are exhibited, and the workability is increased.

With respect to 100 parts by weight of the polylactic acid, the lactic acid monomer may be mixed 20 to 30 parts by weight. When the monomer is mixed in less than 20 parts by weight, the number average molecular weight is high and hard to be used as a pressure-sensitive adhesive, when the monomer exceeds 40 parts by weight migration may occur on the surface and may also be difficult to use as an adhesive.

It is preferable that the mixing ratio of the petroleum resin and the biodegradable hypoallergenic resin is 1 to 2: 1 (w / w). When the mixing ratio of the petroleum resin is too high, the biodegradable hypoallergenic effect is less likely to occur. If the mixing ratio is too high, economic efficiency may be lowered and the overall adhesive effect may be lowered.

In addition, the content of the tackifying resin is preferably 5 to 40 parts by weight relative to the total composition. If the content is less than 5 parts by weight, the effect of lowering the melt viscosity due to the addition of the tackifying resin is insufficient, and there is a fear that the increase in the melt flow index is not so large that the workability may not be satisfactorily reached, and the content is more than 30 parts by weight. If the melt flow index increase rate due to the excess of the tackifier resin is not large, the economical efficiency is lowered and the content of the thermoplastic polymer is relatively reduced, thereby reducing the overall physical properties of the composition.

The rosin acts to improve the overall adhesion of the adhesive composition and is harmless to the human body and acts as a natural preservative. The content of the rosin is preferably 1 to 5 parts by weight based on the total composition. If the content is less than 1 part by weight, it is difficult to obtain an effect of improving the adhesive strength, and if the content exceeds 5 parts by weight, there is a problem in that the adhesion is increased during processing, making it difficult to process the product.

The plasticizer is used to impart flexibility and adhesion to the polymer, and the type of plasticizer according to the present invention is not particularly limited, and for example, sorbitol, ethylene glycol, glycerin, glycerin diacetate, and pentaerythritol It may consist of one or more selected from the group consisting of.

The amount of the plasticizer is preferably 1 to 10 parts by weight based on the total composition. If the content is less than 1 part by weight, the effect of the addition of the plasticizer is insignificant. If the content is more than 10 parts by weight, the economical efficiency may be reduced by excessive use of the plasticizer, and there is a concern that the overall physical properties of the adhesive may be lowered.

The filler is used to control the reinforcement and flow of the composition. The type of filler is not particularly limited, and for example, calcium carbonate, clay, bentonite, calcium stearate or the like can be used.

On the other hand, the adhesive composition of the present invention is applied to the lower surface of the adhesive line 300, odor and bacteria are likely to occur in the application environment. Therefore, in order to reduce the odor and bacteria generation while controlling the reinforcement and flow of the adhesive composition, it is preferable to use a mixture of stone powder and pulp powder as a filler. Stone powder can achieve high strength without using additives due to the compactness of the particles, and the cracking of the adhesive hardly occurs even when the temperature change is large due to low volumetric strain according to the surrounding environment.

The stone powder may be used in the form of powder of various rocks such as loess, marble, ganban stone, granite, jadeite, preferably characterized in that the loess has various functions such as antibacterial, anti-fungal, UV emission.

The pulp powder serves to agglomerate the stone powders while sucking the liquid components, to improve the miscibility and improve the cohesion between the components. At this time, the stone powder and the pulp powder is preferably mixed in a ratio of about 7: 3 to 8: 2 (w / w).

The content of the filler is preferably 1 to 10 parts by weight based on the total composition. If the content is less than 1 part by weight, the effect of adding the filler is insignificant, and if the content is more than 10 parts by weight, there is a concern that the overall physical properties of the adhesive may be lowered.

The antioxidant is intended to improve the change in viscosity, yellowing, deterioration of adhesion and degradation of durability due to oxidation and decomposition, and the type thereof is not particularly limited, and specifically, phenols, aromatic amines, citric acid, or ascorbic acid may be used. Can be.

The content of the antioxidant is preferably 0.1 to 1 parts by weight relative to the total composition. If the content is less than 0.1 part by weight, the effect of the addition of the antioxidant is insignificant, and if the content exceeds 1 part by weight, not only the economical efficiency of the adhesive is lowered but also the overall physical properties may be lowered.

On the other hand, the adhesive composition of the present invention may further include a nano silica that can be uniformly distributed on the lower surface of the adhesion line 300 to improve the adhesion. At this time, the content of the nano silica is preferably 0.1 to 5 parts by weight, and the size of the nano silica (primary particles) is preferably 100 nm or less.

If the content of the nano-silica is less than 0.1 parts by weight, the effect of the addition of nano-silica is insignificant, and if the content exceeds 5 parts by weight, not only the adhesive force is lowered but also a bad phenomenon that blooming (blooming) occurs on the surface of the adhesive over time May occur.

Hereinafter, the configuration of the present invention and its effects through specific examples and comparative examples will be described in more detail. However, this embodiment is intended to illustrate the present invention in more detail, and the scope of the present invention is not limited to these examples.

Example 1

60 parts by weight of ethylene-vinylacetate copolymer, 25 parts by weight of Sukorez D-300, 3 parts by weight of rosin, 5 parts by weight of ethylene glycol, 4 parts by weight of ocherite, 2 parts by weight of pulp powder and 1 part by weight of ascorbic acid. Melt kneading at ° C to prepare an adhesive composition and then molded into pellets. At this time, the biodegradable hypoallergenic resin was prepared by melt-mixing 2.5 parts by weight of lactic acid monomer to 100 parts by weight of polylactic acid at 160 ° C. for 5 minutes.

Example 2

60 parts by weight of ethylene-vinylacetate copolymer, 15 parts by weight of Sukorez D-300, 10 parts by weight of biodegradable hypoallergenic resin, 3 parts by weight of rosin, 5 parts by weight of ethylene glycol, 4 parts by weight of loess, 2 parts by weight of pulp powder and ascorb 1 part by weight of acid was mixed and melt kneaded at 170 to 180 ° C. to prepare an adhesive composition, and then molded into pellets. At this time, the biodegradable hypoallergenic resin was prepared by melt-mixing 2.5 parts by weight of lactic acid monomer to 100 parts by weight of polylactic acid at 160 ° C. for 5 minutes.

Example 3

Except for adding 1 part by weight of nanosilica, it was prepared in the same manner as in Example 1, and was made as Example 3.

[Comparative Example]

Experimental Example

(1) Mesh adhesive strength

In order to evaluate the mesh adhesive strength of the hot melt adhesive, the adhesive pellet quantified on the lower surface of the adhesive line 300 was melt-coated at 170 ° C., and then pressed at a pressure of 60 kgf / cm 2 for 30 seconds at 130 ° C. It progressed and measured the mesh adhesive strength (kgf / cm <2>).

(2) Melt Flow Index

The heating cylinder of the melt flow rate meter was filled with a pellet type adhesive and melted at 160 ° C. for about 5 minutes. The weight (g) of the adhesive passed through the cylinder for 10 minutes was measured by putting a weight of 3 kg.

As can be seen from the table, it was confirmed that the adhesive composition of the present invention has improved adhesion and flow index than the existing product, even when using a biodegradable hypoallergenic resin it was confirmed that the adhesion and flow index does not fall significantly. Also, when the nano-silica is mixed, the flow index can be seen to increase significantly.
