With the recent rapid development of Seiko Industries, the demand for steel-clad laminates for printed wiring circuits is rapidly increasing, and the demand for flame-retardant tights is increasing significantly.

Previously, epoxy resins were the mainstream in this field, but unsaturated polyester resins are being used because they are comparatively low cost and have excellent electrical performance such as arc resistance and tracking resistance. The things that are used are starting to attract attention. In addition, in order to create a circuit using these materials, holes have traditionally been made using an ultra-high-speed drill, but this requires high IW dimensional accuracy and requires extremely expensive equipment. Moreover, the drawback was that it required processing time. In contrast, it has been a long-standing dream of the industry to make it possible to make holes by punching, unlike conventional paper-based laminates, thereby shortening the processing time and simplifying the process.

Furthermore, it is essential that the solid resin used in the present invention contains 0.5 to 5.0% of each of phosphorus and silica. The aim is to promote the chemical action and increase the effect with less stimulant haloquine. Below this level, the effect cannot be fully demonstrated, and above this level, the effect is not much different, and moreover, the effects are the same. This is also undesirable since it may cause deterioration. It is also preferable because it inhibits the decomposition of the halocarbon group at heavy temperatures and converts it into JZ.

Furthermore, for the solid unsaturated polyester containing 1, halogen, and nitrogen, the solid unsaturated polyester contains 1, halogen, and nitrogen.
Alternatively, it is preferable to contain 5 to 30 epoxy compounds as a stabilizer, based on the amount of halokene a411 (actual BrJ calculation) in the resin. The effects of these stabilizers tend to occur when exposed to semi-high temperature regions for long periods of time, such as during processing such as soldering of bullet wiring during the deposition of the d layer, and during use in mounting. Thermal decomposition of halogen groups and the accompanying deterioration of performance are suppressed as much as possible. Salts, noalkyltin, sulfur-based compound salts, etc., and epoxy-based compounds include alicyclic polyepoxy compounds or low-molecular monoepoxy compounds, etc. It is.

In addition, the above-mentioned resin contains an inorganic thixotropy agent (such as fine particle silica) as appropriate, and in Varnish Q mixed with water-containing alumina, uniform coating and impregnation can be achieved by suppressing the precipitation. It has a multifaceted effect that makes it easier to use, and also has the effect of preventing the stickiness of the 7° leg of dry glue, and also has the effect of suppressing the flow of resin excessively during pressure molding.

In the present invention, in order to obtain each Eft performance in a well-balanced manner, it is necessary to appropriately combine the Noril legs of these two types of tights, which have quite different properties, and the preferred configuration of the 7° leg legs is as follows. Surface layer (one is 1, i′+′
I (lower) is made of lath cloth base material, and the inner layer is glass base material. If all Norisoreg is made of only glass cloth base material, the adhesion, mechanical strength and heat resistance of the copper foil (prevention of warping and flanneling during heating, etc.) will be improved, but the flame resistance will be reduced, and holes due to gunching will be reduced. Drilling is extremely difficult, and if the entire material is made of glass base material, the punching performance is good, but the mechanical strength and heat resistance are poor, both of which are undesirable.

The interrelationships and effects of halide content (Br/n), phosphorus content, and nitrogen content have already been explained in the resin section, and in conjunction with the interaction with water-use alumina, they are even more important. The effect becomes noticeable. The structure of the laminate is that both surface layers (one under the copper foil) are glass fiber cloth, and the first layer is glass paper.
However, this point is also different from the one already explained in the prepreg section.The 'l-1111 clad laminate of the present invention has the above composition,
If the structure is adopted, any manufacturing method can be used equally effectively. Glass fiber content m
As for t, it is safe to use at least 20φ in order to maintain 1f, and if it is 1.30% or more, it will be as strong as JVI.
Although it has the ability to maintain flame retardancy, the amount of resin required to maintain moldability is extremely large, making the water-use alumina too weak and requiring an inner cone to maintain flame retardancy.

In addition, the prepreg for the surface layer used in combination with glass paste and glue/reg uses Glass I-B base material that does not contain water-containing alumina, and is suitable for thin sheets of 2.0- or less that can be punched at room temperature. Therefore, the laminate requires a balance of both prepregs. However, taking these points into consideration, it is also necessary to view the cutting for the entire h* layer plate, and the ratio of resin/water/alumina is on the resin excess side, and is 0.85 to 2.7 (preferably t /'i1
.. 0 to 2.0) is appropriate.

If the amount is less than this, the moldability will be poor, and if it is more than this, the flame retardancy will be deteriorated, so both are not preferable.

In terms of the balance between these three factors, if the water content of 4-day alumina is less than 20%, it will be difficult to maintain flame retardancy, and if it is more than 40 φ, the formability will be significantly impaired, so both are undesirable. Similarly, if the amount of resin is less than 35%, the moldability will be impaired, and if it is more than 5 parts, the flammability will be impaired by 1"J, which is not desirable.
