The present invention relate generally to be used to strengthen mixture through the coated fiber pigtail, more specifically relate to can be compatible with the base material that mixes this fibre strand through the coated fiber pigtail.

In the thermoset molding operation, need good " drenching " (" wet-through ") performance (polymeric substrate infiltration mat or fabric) and " moistening " (" wet-out ") performance (each fibrous bundle or fibre strand in polymeric substrate infiltration mat or the fabric).In contrast, in typical thermoplastic moulded operation, major concern be good dispersiveness (being the well distributed property of fiber in thermoplastic material).

Be made into by fibre strand fabric with the situation that forms mixture or laminated thing under; fibre strand is except will having good drenched property and wettability; also wish the lip-deep coating protection fiber of fibre strand avoid in the course of processing wearing and tearing, good weavability (especially on air-jet loom) is provided, and compatible with fibre strand polymeric substrate wherein.Yet many starching components can not be compatible with polymeric substrate, can the bounding force between glass fibre and the polymeric substrate be had a negative impact.For example, textile fibres starching component commonly used--starch usually just can not be compatible with polymeric substrate.As a result, these inconsistent materials must be removed from fabric before with the polymeric substrate dipping.

Available multiple technologies remove described can not with the sizing agent of resin compatible, promptly fabric is carried out degreasing or de-oiling.Removing these can not be to make Woven fabric be in high temperature for a long time with thermolysis sizing agent (this method is commonly called heat cleaning) with the most popular method of the sizing agent of resin compatible.Conventional heat cleaning is included in 380 ℃ and adds heating fabric 60-80 hour.Yet these thermal cleaning steps are disadvantageous to the intensity of glass fibre, can fully successfully not remove inconsistent material, and fabric is stain by the sizing agent degradation production.Attempted other and removed the method for sizing agent, as WATER-WASHING METHOD and/or chemical removal method.Yet these methods usually need significantly to change the composition of size composition, adapting to above-mentioned washing and/or chemistry is removed operation, and remove aspect all incompatible sizing agents so effective not as heat cleaning usually.

In addition, because weaving process is very big to the wearing and tearing of fiberglass yarn, therefore the fiberglass yarn as warp thread will carry out the coating step second time (being commonly called " warp sizing (slashing) ") usually before weaving, make warp thread coat wear-resistant coating (being commonly called " warp sizing slurry layer "), be beneficial to make the wearing and tearing of glass fibre to be reduced to minimum.Warp sizing slurry layer is applied in the first slurry layer outside usually, and the described first slurry layer is coated on the glass fibre in becoming fine operation in advance.Yet because typical warp sizing slurry layer is not compatible with polymeric substrate usually yet, so they also must be removed from Woven fabric before sneaking into resin.

In addition, in order to improve bonding between degreasing or de-oiling fabric and the fluoropolymer resin, need in another procedure of processing (being commonly called " arrangement "), apply arrangement slurry layer (finishing size) (normally silane coupling agent and water), coated glass fiber again to fabric.

The procedure of processing of all these no added values (warp sizing, degreasing or de-oiling and arrangement) all can prolong time production cycle of fabric and raise the cost.In addition, these procedure of processings usually need be in great amount of investment aspect production unit and the labour.And these procedure of processings may cause fabric to damage and the reduction quality to the extra process of fabric.

People have made great efforts to attempt improving the efficient or the validity of some above-mentioned procedure of processings.Yet still need to satisfy the coating of following one or more requirements: suppress the wearing and tearing and the fracture of glass fibre; Compatible with multiple base material; Drenched property and the wettability good with base material is provided.In addition, if coating can be suitable for modern air-jet loom to boost productivity then better.And, preferably in forming, saves in fabric the procedure of processing of these no added values, and still keep the electronics carrying to use required fabric quality and good laminated rerum natura energy is provided.

As previously mentioned, weave in the operation in the routine that the electronic component carrier is used, warp thread scribbled the warp sizing layer usually before weaving, to help the wearing and tearing that prevent warp thread in the weaving process.Usually make warp thread through containing the dip pan or the impregnation bath of warp sizing composition, remove excess stock through one or more sets extrusion rolls then, so with on the warp sizing composition paint warp thread.Common warp sizing composition can comprise for example film forming material, softening agent and lubricant.The film forming material that is generally used for the warp sizing composition is a polyvinyl alcohol.After warp sizing, dry warp thread also is wound on it on loom spool.The number of warp thread end and spacing depend on the pattern of fabric knitting.Because the combination of initial spreading mass and warp sizing material, through the dried loss on ignition of the warp thread of starching usually greater than 2.0%.

Usually, when adding is used to make the electronic component carrier as reinforce with fabric, warp sizing material and starch/oily spreading mass usually can not be compatible with mixture manufacturers used polymer resin material, therefore must clean removing all basically organic materialss fabric, and then Woven fabric is flooded from fiberglass surfacing.This can finish by several different methods, for example cleans fabric, or more generally is with well known mode fabric to be heat-treated.Therefore the result of clean operation can make and be used for not having suitable interface between the polymeric substrate of impregnate fabric and the fiberglass surfacing through cleaning, must apply coupling agent to fiberglass surfacing.This operation is called arrangement by these those skilled in the art sometimes.Arrangement starching layer can obtain LOI usually less than 0.1% fabric.

Arrangement starching layer floods this fabric with the compatible polymer base material after handling, and pushes the aforesaid semicure prepreg of dry then formation between a cover metering roll.About making the more information of electronic circuit board, can referring to The electronic material handbook(Electronic Materials Handbook ^TM), ASMInternational (1989), 113-115 page or leaf, R.Tummala (Ed.)

Because the warp sizing process applied thicker coating on warp thread, so this warp thread becomes comparatively firm and loses flexibility with comparing without the warp thread of starching.The warp sizing material tends to make warp thread to keep together and forms the bundle closely that the cross section is generally circle.Though do not wish to limit the present invention, this knot structure ` restraints closely and cross section is roughly circle) be considered to when procedure of processing (as preimpregnation) subsequently, can hinder polymer resin material to infiltrate warp thread, also have this situation even if remove the warp sizing material.

Although warp sizing does not have disadvantageous effect to the present invention, neither be preferred.Therefore in preferred embodiment of the present invention, warp thread did not carry out the starching step before weaving, and did not therefore mainly contain warp sizing material residue.Term used herein " does not mainly contain " and is meant that warp thread contains and is less than 20 weight %, is more preferably the warp sizing material residue that is less than 5 weight %.At one more preferably in the example of the present invention, warp thread did not carry out the warp sizing step before weaving, and was substantially free of warp sizing material residue.Term used herein " is substantially free of " and is meant that warp thread contains in its surface and is less than 0.5 weight %, is more preferably to be less than 0.1 weight %, preferably the warp sizing material residue of 0 weight %.Yet, if having carried out secondary before weaving, warp thread applies operation, the consumption of secondary coating better is 0.7 weight % less than sized warp weight on the paint warp thread surface before weaving.

In another preferred embodiment of the present invention, the loss on ignition of warp thread better is to be lower than 2.5 weight % in the weaving process, is more preferably to be lower than 1.5 weight %, preferably is lower than 0.8 weight %.In addition, total loss on ignition of fabric of the present invention better is 0.1-1.6%, is more preferably 0.4-1.3%, is 0.6-1% well again.

In another limiting examples of the present invention, warp thread preferably has long cross section and high pigtail degree of opening.Term used herein " long cross section " refers to that warp thread has general flat or elliptoid shape of cross section.As mentioned above, pigtail degree of opening height is meant that each root fiber of yarn or fibre strand is not closely to keep together, but has the feature of open space to help base material infiltrated fiber bundle between one or more single fiber.Cross section and pigtail degree of opening that the warp thread (as mentioned above) of process starching has circle usually are low, therefore can not promote the infiltration of base material.Although do not want to limit the present invention, but resin infiltrates warp thread bundle (be good resin moistening) well and is considered to reduce or eliminate the passage that moisture enters in the laminated thing that makes according to the present invention and the electronic component carrier in the laminated process, thereby improves their overall stability to hydrolysis.This also has an advantage: by

The printed-wiring board (PWB) that above-mentioned laminated thing and electronic component carrier make can reduce the trend that short circuit takes place easily owing to form electroconductibility anode fibril when being in wet condition under the bias voltage.

Degree with F-index experimental measurement pigtail degree of opening.In the test of F-index, make the roller of yarn to be measured through a series of arranged verticals, and be placed near the sensing device (this sensing device comprises the light-emitting area light sensitive face relative with) of horizontal positioned, so that the Z-axis almost parallel of yarn is aimed at light-emitting area and light sensitive face.Sensing device is installed in the vertical height of a half-distance between the roller that is approximately arranged vertical, the horizontal throw of this sensing device and yarn by make roller towards or move away from sensing device and to control.When yarn passed through (usually with about 30 meters/minute speed) on roller, according to the difference of fibre strand degree of opening, the part of yarn or many parts can be sheltered a part of light that sends from light-emitting area, thereby cause the response of light sensitive face.Then, for the yarn (being about 10 meters usually) of given length the numerical value of sheltering is tabulated, gained ratio (being the numerical value of sheltering of per unit length) is considered to measuring of pigtail degree of opening.

It is believed that, the tight warp structures of the fabric that is made into through the glass fiber yarn of warp sizing by routine and the low opening of above-mentioned these yarns, make the ventilation property of these fabrics in general be higher than the ventilation property of preferred fabric of the present invention, preferred fabric of the present invention better is to comprise long warp thread cross section and higher warp thread opening.In another limiting examples of the present invention, the fabric breathability that records according to ASTM D 737 standard test methodss is not more than about 0.05 standard cubic meter/(minute square metre), be more preferably and be not more than about 1.52 standard cubic meter/(minute square metre), preferably be not more than about 0.91 standard cubic meter/(minute square metre).In another example of the present invention, fabric is made into the fabric of 7628 styles, record its ventilation property according to ASTM D 737 standard test methodss and be not more than 0.05 standard cubic meter/(minute square metre), be more preferably and be not more than 1.52 standard cubic meter/(minute square metre), preferably be not more than 0.91 standard cubic meter/(minute square metre).

Do not want to be subjected to the constraint or the restriction of any concrete theory, suppose that the warp thread with elongation or flattened cross-sectional also can help to improve the boring performance of the laminated thing that is made by the fabric that mixes this warp thread.More specifically, owing to have in the fabric of long cross section warp thread between the warp thread and weft yarn on the intersection point, therefore its profiled outline line position is lower than the fabrics in general of the warp thread that mixes circular cross section, and it is less that drill bit drills the glass fibre that fabric contacts when holing, thereby the wearing and tearing that suffer are also less.As previously mentioned, in an example of the present invention, preferably warp thread and weft yarn when being shaped, on it, apply can with the initial coating composition of resin compatible.On the paint warp thread can with the initial coating composition of resin compatible can with the paint weft yarn on can be identical or different with the initial coating composition of resin compatible. used herein with respect on the paint warp thread can be for the initial coating composition of resin compatible " with on the paint weft yarn can be different with the initial coating composition of resin compatible " amount that refers at least a component in the initial coating composition on the paint warp thread is different from the amount of this component in the initial coating composition on the paint weft yarn; Perhaps at least a component is not present in the initial coating composition on the paint weft yarn in the initial coating composition on the paint warp thread, and perhaps at least a component is not present in the initial coating composition on the paint warp thread in the initial coating composition on the paint weft yarn.

In another limiting examples of the present invention, the glass fibre of fabric yarn is the E-glass fibre, and its density is lower than 2.60 gram/cubic centimetres.In another non-limiting preferred embodiment, when the E-glass fiber yarn was made into the fabric of 7628 styles, the tensile strength that the gained fabric is parallel to warp thread direction was greater than the intensity of fabric on warp thread direction in specie mutually through conventional thermal cleaning and arrangement.In a limiting examples of the present invention, preferably can mainly not contain " viscosity " film forming material with the initial coating composition of resin compatible, promptly initial coating composition comprises to haggle over solid amount and is lower than 10 weight %, is more preferably " viscosity " film forming material that is lower than 5 weight %.

In preferred embodiment, can be substantially free of " viscosity " film forming material with the initial coating composition of resin compatible, promptly initial coating composition comprises to haggle over solid amount and is lower than 1 weight %, is more preferably and is lower than 0.5 weight %, preferably is lower than the viscosity film forming material of 0.1 weight %.The viscosity film forming material can have a negative impact to the weaving performance of wanting the yarn above the paint, for example reduces the jet conveying of weft yarn, makes warp thread adhered to one another.A non-limiting object lesson of viscosity film forming material is the water-soluble epoxy resin film forming material.

Existing summary description forms the another kind of method that the present invention is used for the fabric of electronic component carrier, this method may further comprise the steps: (1) obtains at least one weft yarn with many glass fibre, is coated with the first resin compatible coating on the described weft yarn of at least a portion; (2) obtain at least one warp thread, be coated with the second resin compatible coating on the described warp thread of at least a portion with many glass fibre; (3) loss on ignition is made into less than the described at least a warp thread of 2.5 weight % and described at least a weft yarn is applicable to the fabric that strengthens the electronic component carrier.

Existing summary description forms the method for the laminated thing that is applicable to the electronic component carrier.The first step that this method comprises is the fabric that acquisition is made into by at least a weft yarn and at least a warp thread, described at least a weft yarn has many glass fibre, be coated with the first resin compatible coating on the described weft yarn of at least a portion, described at least a warp thread has many glass fibre, be coated with the second resin compatible coating on the described warp thread of at least a portion, the loss on ignition of described warp thread in weaving process is less than 2.5 weight %.In a limiting examples of the present invention, this fabric preferably is substantially free of warp sizing material residue.

As previously mentioned, form in the operation at common fabric, conventionally paste composition on paint glass fibre and/or the yarn (being initial size composition and warp sizing composition) can not with resin compatible, therefore must remove behind these compositions from fabric could be with this fabric of polymeric resin material impregnates.As mentioned above, after weaving, finish usually with the thermal cleaning fabric.Yet thermal cleaning can reduce the intensity (thereby the yarn that reduction makes thus and intensity of fabric) of glass fibre, also can make glass densification (densify).The present invention before weaving on paint warp thread and/or the weft yarn can with the coating of resin compatible owing to need not before dipping, to remove, thereby also need not to carry out thermal cleaning.Therefore, in non-limiting preferred embodiment of the present invention, fabric was not heat-treated and thermal destruction before dipping.

In the fabric forming procedure of this external routine, after removing size composition, before dipping, also must on fabric, apply arrangement starching layer, be used for improving the consistency between fabric and the fluoropolymer resin with thermal cleaning.And in the present invention, before weaving to warp thread and/or weft yarn apply can with the composition of resin compatible, thereby also need not to carry out textile finishing.Therefore, in another preferred embodiment of the present invention, fabric better is the residue that does not mainly contain secondary coating and/or arrangement spreading mass, promptly is less than 15 weight %, is more preferably the residue that is less than 10 weight % secondary coatings and/or arrangement spreading mass.In a better example of the present invention, fabric is substantially free of the residue of secondary coating and/or arrangement spreading mass." being substantially free of " used herein is meant that fabric contains the residue that is less than 1 weight %, is more preferably the secondary coating that is less than 0.5 weight % and/or arrangement spreading mass.

Now the present invention is described in conjunction with following non-limiting specific examples.

Apex point wearing and tearing percentage=100 * (P _i-P _f)/P _i

Wherein, P _iThe original width of=initial cuts sword

P _f=bored and stipulated the hole width of initial cuts sword afterwards

With reference to Figure 11, the girth of the width 1170 usefulness apex points of the initial cuts sword 1172 of drill bit 1174 is measured.

Hole with the single head drilling machine.High 3 layers laminated thing (as mentioned above) that piles up are holed, and this laminated thing has the backing plate of refill phenolic aldehyde coating of aluminium inlet (entry) and the thick 1.88mm (0.074 inch) of thick 0.203mm (0.008 inch).Once drill 3 compound normally standard operations in industry layer by layer.Measure the apex point wearing and tearing percentage of two kinds of diameter 0.35mm (0.0138 inch) and 0.46mm (0.018 inch) drill bit.These two tungsten burs that drill bit all is 508 series are available from Tulon Co., Gardenia, California.It is constant that chipload during boring keeps, and is each instrument 0.001." chipload (chip load) " used herein refer to drill bit insert speed (inch per minute clock) and axle rotating speed (rev/min, ratio rpm).For the drill bit of 0.35mm, the axle rotating speed is 100,000rpm, insert speed and be 100 inches (254cm)/minute.For the drill bit of 0.46mm, the axle rotating speed is 80,000rpm, insert speed and be 80 inches (203cm)/minute.The retraction rate of two kinds of diameter instruments be 2.54m (1000 inches)/minute, the drill bit head upper limit is held constant at 1.65mm (0.065 inch)." drill bit head limit (drill head limit) " used herein is meant that apex point returns to the distance of laminated thing upper surface top.

The apex point percentile measurement of wearing and tearing is based on 500 hole drill sectional hole patterns shown in Figure 12.This boring pattern is included in 391 holes of boring in 0.635cm * 10.16cm (0.25 inch * 4 inches) pieces (1280 part), then being 100 holes in 10 * 10 sectional hole patterns (1282 part), is 9 holes in 3 * 3 sectional hole patterns (1284 part) then.Hole density with 62 hole/square centimeters (400 hole/square inch) is holed in each part.Repeat this pattern three times, bore 2000 holes altogether.Test 1 and test 2 boring with Uniline 2000 single head drilling machines, test 3 boring with CNC-7 single head drilling machine.Two kinds of drilling machines all derive from Esterline Technologies, Bellevue, Washington.

Table 13B illustrate reference examples GG and sample HH for the drill bit of 0.35mm and 0.46mm diameter at apex point wearing and tearing percentage by drill bit after pattern bores 2000 holes as mentioned above.Each test all begins with new apex point.

Table 13B

By table 13B as seen, sample HH (comprising the fiberglass that scribbles the compatible size composition of described herein and laminated thing matrix resin) in the test 1 and 2 compares with reference examples GG (be included in to apply and contain the fiberglass that silane arrangement spreading mass must carry out thermal cleaning before), and its apex point wearing and tearing percentage obviously reduces after boring 2000 holes.Test 3 shows only having a bit aspect the apex point wearing and tearing percentage and improves, but that the reason of this phenomenon is CNC-7 drilling machine used in this test is more outmoded than testing Uniline 2000 drilling machines used in 1 and 2, not too can control in the drill test process.

Location accuracy

The module that is commonly used to evaluate laminated thing boring performance is the location accuracy in hole.Deviation in range between this experimental measurement actual apertures position and the position, predetermined hole.This measurement 3 layer by layer the bottom layer compound lower surface ` that stacks of compound stack the surface of drilling bore hole from laminated thing) carry out because estimate the predetermined i.e. difference maximum of " truly " position, hole of this Kong Weiyu.This difference is evaluated with " offset distance ", the distance between actual positive center of holing on the promptly laminated thing surface and the predetermined positive center, hole.Repeating four aforesaid 500 hole sequences (being that each instrument bores 2000 holes) afterwards, the measured deviation distance.Measure the offset distance of last 100 sectional hole patterns (being last boring part 582) of boring.With the diameter of the Tulon Co. of type as mentioned above is the 508 serial bit bores of 0.46mm (0.018 inch).As what use in the tool wear test, the chipload for 0.001, the axle speed of drill bit is 80,000rpm, inserting speed is 80 inch per minute clocks.Should test for 8 times for each reference examples GG and sample HH repetition, test since a green bit at every turn.

Table 13C illustrates the result who bores the location accuracy test of reference examples GG and sample HH after 2000 holes.

Table 13C

	Reference examples GG	Sample HH
	Reference examples GG	Sample HH	The drill bit number	8	8
