本発明では、塗工工程における金属箔の走行速度に対するコートロールの周速度の比が115〜200%に制御する。該速度比が115%未満では均一な塗工ができなくなり、ポリイミド層の厚みばらつきが発生する。また、200%を超えても塗工ムラ、ポリイミド層の厚みムラが発生する。通常、塗工工程における金属箔の走行速度は0.5〜5m/分程度、また、コートロールの周速度は0.6〜10m/分程度である。 In the present invention, the ratio of the peripheral speed of the coat roll to the running speed of the metal foil in the coating step is controlled to be 115 to 200%. If the speed ratio is less than 115%, uniform coating cannot be performed, and the thickness variation of the polyimide layer occurs. Also, uneven coating, uneven thickness of the polyimide layer to generate 200% super forte. Usually, the traveling speed of the metal foil in the coating step is about 0.5 to 5 m / min, and the peripheral speed of the coat roll is about 0.6 to 10 m / min.

(1)金属箔の弛み(mm)
〔図3〕は金属箔の弛みの測定方法の概要を示す模式図である。〔図3〕に示す如く、幅が684mmである金属箔5を繰り出し軸から、前ガイドロール10と後ガイドロール11の上を通過させる。この時、2本のガイドロール10及び11間を走行する金属箔5を水平に保つ。金属箔5がガイドロール10及び11に接触する点間の距離は1000mmとする。後ガイドロール11を通過した金属箔に5kgの重り12を負荷させ、繰り出し軸にロックし、重り12が地面に接触しないようにする。金属箔5がガイドロール10及び11に接触する箇所の中央位置(一方の接触点から500mmの位置)の部分から金属箔の端面を基準とし、レーザー変位計(キーエンス(株)製、形式:LB−1000)13を用いて全幅についてその変位を測定する。
(2)均一塗布性
FMCL試料を縦横100mmの正方形に切り取り、塩化第二鉄水溶液(40重量%)を用いて金属箔層に化学エッチング処理を施し、ポリイミド層のみとする。ポリイミド層を透過光で観察して、直径10μm以上の穴の有無を観察する。
(3)ポリイミド層の厚みムラ(μm)
前項と同様にしてポリイミド層のみを得る。接触式膜厚計(Heidenhain(株)製、形式:200068G)を用いて、横方向に任意に10点厚みを測定し、その最大値と最低値の差を厚みムラとする。
(1) Looseness of metal foil (mm)
FIG. 3 is a schematic diagram showing an outline of a method for measuring the slack of a metal foil. As shown in FIG. 3, a metal foil 5 having a width of 684 mm is passed from a payout shaft 9 over a front guide roll 10 and a rear guide roll 11 . At this time, the metal foil 5 traveling between the two guide rolls 10 and 11 is kept horizontal. The distance between the points where the metal foil 5 contacts the guide rolls 10 and 11 is 1000 mm. A metal foil which has passed through the rear guide roll 11 to load the weight 12 of 5 kg, to lock the unwinding shaft 9, the weight 12 does not contact the ground. A laser displacement meter (manufactured by KEYENCE CORPORATION, type: LB) from the center position of the place where the metal foil 5 comes into contact with the guide rolls 10 and 11 (500 mm from one contact point) with reference to the end face of the metal foil. The displacement is measured for the entire width using (−1000) 13.
(2) Uniform applicability An FMCL sample is cut into a square of 100 mm in length and width, and a metal foil layer is subjected to a chemical etching treatment using an aqueous ferric chloride solution (40% by weight) to obtain only a polyimide layer. The polyimide layer is observed with transmitted light, and the presence or absence of a hole having a diameter of 10 μm or more is observed.
(3) Thickness unevenness of polyimide layer (μm)
Only the polyimide layer is obtained in the same manner as in the previous section. Using a contact-type film thickness meter (Heidenhain Co., Ltd., model: 200068G), the thickness at 10 points is arbitrarily measured in the horizontal direction, and the difference between the maximum value and the minimum value is defined as the thickness unevenness.
