Abstract

PURPOSE:To laminate an overlay film under pressure without applying 'squeezing' to a circuit and the overlay film, by a method wherein a substrate having the circuit adhered thereto and the overlay film are integrally held between metal belts and pressed by a hot roll on the way of feed to be laminated before cooled under pressure by a cooling roll. CONSTITUTION:A substrate 2 and an overlay film 3 are held between two belts 22, 27 to be fed and heated in an oven 13 to vent air and successively pressed by rolls, 30, 31, 32, 33 of a hot roll unit 14. Since the substrate 2 and the overlay film 3 are held between the belts 22, 27 and indirectly pressed, both of them receive force due to a plane and effect due to the core shift of the rolls 30-33 and the change in pressure balance is removed. Further, the substrate 2 and the overlay film 3 are pressed and cooled in a state held between the belts 22, 27 by a cooling roll 15 and the overlay film 3 laminated to the substrate 2 receives no 'squeezing' even by the cooling roll 15 and dimensional stability is secured.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional laminator, since the laminator directly sandwiches and presses the substrate and the overlay film, pressure roll speed differences, misalignment, and
Due to changes in pressure balance, the circuit 1, substrate 2, and overlay film 3 are "strained" in the direction of arrow A or B in FIG. 3, or in the right or left direction, and the overlay film 3
The occurrence of the wrinkles tends to cause wrinkles in the circuit 1 and the overlay film 3, to create a gap 5 called an air pocket between the circuit 1 and the overlay film 3, or to cause insufficient adhesion of the overlay film 3 to the substrate 2. Not only does this reduce the commercial value of the product, but it also lacks stability in the dimensions of the circuit, leading to defective products. Lack of elasticity causes wrinkles or voids.

(Function) A substrate with a circuit glued between two metal belts of a belt conveyance mechanism and an overlay film placed on the substrate so as to cover the circuit are integrally sandwiched between these substrates and an overlay. The film is transported integrally with the belt transport mechanism. During the VA feeding, the substrate and overlay film are heated in an oven, and then the substrate and overlay film are pressed together by a hot roll through each of these metal belts to form an a1 layer. After the overlay film is laminated onto the substrate, the overlay film is further cooled under pressure with a cooling roll via each of the metal belts to complete the lamination of the overlay film. The speed difference between the two rolls is absorbed by the rolls sliding on the surface of the metal belt. This produces a printed circuit board.

(Effects of the Invention) As explained above, according to the present invention, in an overlay lamination apparatus that forms a printed circuit board by forming an overlay film covering a circuit pattern on a substrate to which a circuit pattern is bonded, and laminating the same with a laminator. , a belt conveyance mechanism that integrally conveys the substrate on which the overlay film is placed between two metal belts provided with elastic members; a heat roll that presses the overlay film and the substrate together through the belt conveyance mechanism; Since the structure is equipped with a cooling roll, when the overlay film is laminated on the board, a planar force is indirectly applied to the board, the overlay film, and the circuit pattern to prevent misalignment of the rolls. , the effects of changes in pressure balance, etc. are eliminated, and since each of the belts is made of metal, even if a speed difference occurs between the rolls, the speed difference is absorbed by the slippage of the rolls. , the substrate, the overlay film, and the circuit pattern are not subjected to "straining", and the overlay film can be prevented from being wrinkled and air trapped, and the dimensional stability of the circuit pattern can be ensured. Furthermore, it is possible to significantly improve the adhesion between the substrate and the overlay film 3, and it is possible to produce a high-quality and extremely good printed circuit board, while also limiting the range of allowable conditions during production. Since it can be made wide, it becomes possible to easily manufacture the circuit board.

Furthermore, in an overlay lamination apparatus that forms a printed circuit board by placing an overlay film covering the circuit pattern on the board on which the circuit pattern is adhered, and laminating them using a laminator, the board on which the overlay film is placed is covered with an elastic member. a belt conveyance mechanism that integrally conveys these by sandwiching them between two metal belts; and a belt conveyance mechanism that integrally presses the overlay film and the substrate via each of the metal belts disposed on the belt conveyance mechanism. a heat roll, an oven disposed upstream of the heat roll of the belt conveyance mechanism and heating the overlay film and the substrate, and an oven disposed downstream of the heat roll of the belt mechanism and passing through each of the metal belts. By having a configuration including a cooling roll that presses the overlay film and the substrate, it becomes possible to more effectively remove air accumulated between the substrate, the overlay film, and the circuit pattern. This has the excellent effect of further suppressing the occurrence of air pockets.
