Description
Technical field
The present invention relates to when the conveyance of chip-type electronic component etc., as the lamination band of the wrapping material of this electronic unit of packing etc.
Background technology
As the method for conveyance chip part, known have this electronic component packing is carried out conveyance in wrapping material band to twine the spool mode.Twine in the spool mode at this band, on the length direction of banded ground paper, accommodate subchassis on the carrying band (papery is packed base material) of usefulness bag every certain chip type component that is interval with, from top heat-sealing cover tape (top band) and seal, carry out conveyance after being curled into reel.After the conveyance, peeling off cover tape in the production process of circuit substrate etc., with air adsorption nozzle absorbent core chip part, is present trend with its mode that is installed on the substrate.
Be wound to the series of processes of supply substrate chip from such band, the cover tape for as the electronic component packing material in order to supply chip effectively, requires it to have following performance.That is, (1) has good tackiness to papery packing base material.When (2) peeling off cover tape, have stable separability, can not pack base material and produce fine hair, can when parts are installed, not give rise to trouble from papery.(3) suppress because chip the flying out from bag that the stripping charge that produces when peeling off cover tape causes promptly prevented the charging property excellence.(4) in carrying the way, can to cause that parts stick to cover tape not first-class owing to envrionment conditions.
Particularly in recent years, in chip-type electronic component, part dimension is miniaturization day by day, and the papery that produces when peeling off cover tape packing substrate surface layer has the phenomenon (generation fine hair) of peeling off to wait the bad influence of adsorption nozzle generation to fitting machine, has produced the problem that causes installation rate reduction etc.Therefore, particularly in the cover tape of the packing that is used for minimum parts etc., have good separability, the surface of papery packing base material does not produce fine hair and anti-charging property is important performance when peeling off, and expects such cover tape.
Method as the stripping charge pressure that suppresses wrapping material, a kind of cover tape combination has been proposed, it possesses: on the surface or inside contain and be selected from the polyvinyl acetate esters resin, ethene copolymer, the packing base material of at least a kind of composition in acrylic resin and the paraffin class, and adopt to contain and be selected from the olefinic copolymer that intramolecularly contains carboxyl or amino oxygen base, ionic cross-linked polymer resin, and the formed tacky resin layer of the resin combination of at least a kind of polymkeric substance in the segmented copolymer of aromatic ethenyl compound and conjugated diene compound (referring to patent documentation 1).In the method, owing to can't obtain effect under the situation of different types of base material of combination and cover tape, therefore expectation all can be brought into play the cover tape of anti-charging property regardless of the kind of the base material of combination.
In addition, as cover tape with anti-charging property, known have the adhesive layer that will mix anti-live agent (tensio-active agent=low molecule-type anti-live agent) in polyolefin resin to be laminated to the cover tape (referring to patent documentation 2) that obtains on the support base material by the middle layer. this cover tape, reduced stripping strength owing to be seeped into cover tape as the low molecule-type anti-live agent of anti-live agent blended with the interface of papery packing base material. therefore in order to ensure the gluing tackifier that mix, yet to keep stripping strength., because the low molecular composition anti-live agent moves in adhesive layer, therefore raise with the adhesive power of paper wrapper layer sometimes, sometimes local adhesive power rising etc., when peeling off cover tape, the surface of pull-up paper wrapper and produce fine hair. such cover tape can be fully practical according to the size of parts etc., but in the chip-type electronic component of very small dimensions, the papery packing substrate surface layer peeling phenomenon (generation fine hair) that produce when peeling off cover tape etc. produce bad influence to the adsorption nozzle of fitting machine, generation causes the problem of installation rate reduction etc. therefore, particularly concerning the cover tape of packing of being used for widget etc., has good separability, and the surface of papery packing base material does not produce fine hair and anti-charging property is important performance equally when peeling off.
In addition, the surface resistivity of adhesive layer thus as preventing the method that surface of pressure-sensitive adhesive is charged, has been studied the method (referring to patent documentation 3) of mixing the polymer anti-live agent in tackiness agent along with the humidity temperature changes.In such cover tape, in order to ensure in tackiness agent, having mixed a large amount of tackifier with the tackiness of carrying belt material paper, therefore adhesive power is bigger than suitable value, separability reduces in time, cause peel off (the generation fine hair) of papery packing substrate surface paper fiber, sometimes cause not good in the installation, there is not the cover tape of these problems in expectation.
In addition, because what produce when papery packing base material is peeled off cover tape peels off vibration (buffeting), chip part in the carrying belt material paper empty chamber produces inclination or the phenomenon (chip flies out) that flies out from cavity etc., during by air adsorption nozzle absorbent core chip part, can't adsorb in correct position, thereby cause that the installation rate descends.The problem of peeling off vibration like this is along with the miniaturization of chip part, lightweight development are more and more obvious.In addition, even use with a kind of cover tape, because the kind of carrying belt material paper and batch different and adhesive strength is different, in order to peel off cover tape with certain peeling force and to reduce and peel off vibration, need pack the kind of base material and change in batches according to papery and be adjusted at crimping condition in the band wrapping machine etc., thereby need high-caliber management.Therefore, expect a kind of kind of carrying belt material paper and in batches, under certain crimping condition, can stably show certain adhesive power of not relying on, and be difficult to produce and peel off the cover tape of vibration.

13The problem of adhesive layer etc. in few chip part, takes place to stick to owing to static in Ω/.In addition, if the blending ratio of polymer anti-live agent is too much, then anti-charging property is good, but glueability reduces the adhesive power that can't obtain expecting.In addition, except the polymer anti-live agent, can also unite and use normally used low molecule-type anti-live agent (tensio-active agent) with the adjustment sheet surface resistivity.Consumption to low molecule-type anti-live agent at this moment has no particular limits, and can be no more than for example interior suitably selection of scope of 5 weight % with respect to 100 weight part base polymers.If the combined amount of low molecule-type anti-live agent is too much, low molecule-type anti-live agent is seeped into the problem on hot glue adhesive layer surface etc. sometimes, is not preferred therefore.
As the polymer anti-live agent, can use the polymkeric substance that has anti-charging property arbitrarily, unqualified to it.The polyamide-based multipolymer, calcium ion cross-linked polymer that can enumerate polyether ester amides etc. for example etc. contain carboxylate salt polymkeric substance, contain the multipolymer of quaternary ammonium salt etc.The polymer anti-live agent can not move in adhesive layer as low molecule-type anti-live agent and the surface of emersion adhesive layer etc., therefore by using the polymer anti-live agent, can obtain anti-charging property and tackiness steady in a long-term.For example, can make the surface resistivity of adhesive layer 10
13Ω/ or following (for example 10
8～10
13About Ω/), preferably 10
9～10
12About Ω/.In addition, for adhesive power, also can keep suitable adhesive power 10～70gf (98.1mN～687m N) steadily in the long term.
As the polymer anti-live agent, can be fit to use for example polyether ester amides; The segmented copolymer of polyolefine and polyethers; The polymkeric substance that polyvinyl ether and ethylene glycol constitute etc. contains the polymer anti-live agent of polyether structure.If use the polymer anti-live agent that contains polyether structure, when then heat sealing packaging material is peeled off after with the lamination band on the packing base material, polyether components remains in base material one side, a part that forms the anti-live agent in the tackiness agent is transferred to the form of packing substrate surface, therefore the kind of tube packaging base material (raw material) not all can have been given play to high anti-charged effect.For example, behind heat-sealing laminated belt for package material of the present invention on the papery packing base material, (23 ℃ * 65%RH of the absolute values that the stripping charge that produces hot glue adhesive layer when papery packing base material is peeled off is pressed, 180 ° of peel angle, peeling rate 5000mm/ branch, electrode and adhesive layer apart from 5mm) under the situation of using any papery packing base material, be 200V or following.
In addition, when peeling off in the residual polyether components of base material one side, even for the packing of papery arbitrarily base material commonly used usually, under certain condition under Re Feng the situation, can demonstrate certain adhesive power. for example, under 190 ℃, make the paper package base material that paper produces more in north: the paper package base material that paper produces is made in trade(brand)name " HOCTO40 " and north more: trade(brand)name " HOCTO40E " goes up under the situation of heat-sealing laminated belt for package material of the present invention, for the adhesive power of paper package base material " HOCTO40E " is in for the adhesive power of paper package base material " HOCTO40 " 2 times. according to the inventor's research, in papery packing base material commonly used usually, paper package base material " HOCTO40 " contains low molecule-type anti-live agent to not containing the polymer anti-live agent tackiness agent demonstrates minimum adhesive power, paper package base material " HOCTO40E " contains low molecule-type anti-live agent to not containing the polymer anti-live agent tackiness agent demonstrates the highest adhesive power. for example, under 190 ℃, produce at Fuji's republicanism paper: trade(brand)name " FK-42 ", system paper in Tokyo produces: trade(brand)name " TK-43 ", Oji Paper produces: when sealing laminated belt for package material of the present invention on trade(brand)name " HJ-42 " the etc.s papery packing base material commonly used usually, below adhesive power when its adhesive power all is under 190 ℃ to seal laminated belt for package material of the present invention arbitrarily on papery packing base material " HOCTO40E ", and be in going up below 2 times of adhesive power when sealing laminated belt for package material of the present invention at papery packing base material " HOCTO40 " under 190 ℃.
The polymer anti-live agent that contains polyether structure can use known material commonly used, and it is had no particular limits, and can be particularly suitable for using the polymer anti-live agent that contains polyether ester amides.The molecular-weight average that the polymeric amide that can illustration for example has a carboxyl by two ends and poly-(oxyalkylene group) glycol reaction obtain is the polymer anti-live agent that constitutes of about 8000～100000 polyether ester amides etc.The polymer anti-live agent is according to the kind of base polymer and tackifying resin, and consideration intermiscibility and other rerum natura, can suitably select to use.In addition, it is rotten etc. that the high temperature when preventing to extrude lamination and heat-sealing causes, the preferred heat decomposition temperature of polymer anti-live agent be 120 ℃ or more than.
The combined amount of tackifying resin and polymer anti-live agent can be selected in above-mentioned scope respectively, but with respect to 100 weight part base polymers, the summation of the addition of tackifying resin and polymer anti-live agent is preferably at 33 weight parts or following, further preferred in 30 weight parts or following scope selection.If the summation of the addition of tackifying resin and polymer anti-live agent in this scope, owing to can further be suppressed the time dependent laminated belt for package material of characteristic such as adhesive power and surface resistivity, is preferred therefore.
In addition,, can add antioxidant, ultraviolet screener, coupling agent as required, consider the workability when making, can also add releasing agent, filler etc. as the constituent of adhesive layer.In addition, can also unite the anti-live agent of use except that above-mentioned etc.
Above-mentioned base polymer is by melt blending tackifying resin, polymer anti-live agent and other composition of adding as required, can obtain constituting the adhesive compound of the adhesive layer of laminated belt for package material of the present invention.This adhesive compound is configured as particle diameter is the ball shape of about 3m m, preservation in the time of 24 hours in the constant temperature and humidity machine of 35 ℃ * 80%RH condition, the water ratio of this adhesive compound be preferably 0.5% or below, be preferably especially 0.3% or below.If the water ratio after the moisture absorption is in this scope, then the laminated belt for package material that is made of this tackiness agent of adhesive layer particularly can suppress because the variation of the adhesive power that environmental change causes, stably continues the adhesive power of expectation.Especially in above-mentioned water ratio scope, can significantly suppress under the high humidity and the decline of adhesive power during dewfall.
From the viewpoint of tackiness and the property handled etc., the thickness of the adhesive layer that is made of mentioned component is preferably 5～50 μ m, is preferably especially about 10～30 μ m.When the thickness less than 5 μ m of adhesive layer, can't obtain enough adhesive powers sometimes, if thicker, when heat-sealing, produce because tackiness agent oozes out and the trouble of pollution zone wrapping machine etc. sometimes than 50 μ m.
In the present invention, between above-mentioned support substrate layer and adhesive layer, in order to improve both adaptations, the middle layer can also be set. this middle layer can be made of thermoplastic resins such as for example polyolefin resin, thermoplastic elastomer etc. and these compositions can use separately, or use mixing more than 2 kinds or 2 kinds. and polyolefin resin can use as the above-mentioned illustrative material of thermoplastic elastomer.
As the thickness in middle layer, can in not damaging productivity in the manufacturing process, the scope of operability when making the lamination band, suitably select, for example, if under the situation that adopts laminating to make, then be generally about 5 μ m～30 μ m.
Lamination band of the present invention can be made as follows: for example with the constituent of mixed adhesive layer of regulation; in two kneaders by melt blending pillization or carry out dry type and mix; the material that obtains is adopted independent or series connection extruded layer platen press commonly used; by the middle layer or not by the middle layer, make supporting layers on substrates moulding adhesive layer.In addition, adhesive layer and middle layer can also be laminated to by the co-extrusion laminating method and support substrate layer to make.
Laminated belt for package material when the lamination band that obtains like this can be suitable as chip-type electronic components such as conveyance chip fixed resistor constant resistance device, laminated ceramic compacitor etc.Particularly after heat-sealing on the papery packing base material, the separability excellence when peeling off can not produce under the filoplume at the paper fiber that papery is packed the substrate surface layer and peels off.
