Example Embodiment

[0111] Example

[0112] The resin paint shown in Table 1 was coated on one side of an aluminum foil (1000 series alloy, elastic limit stress: 140 MPa) with a thickness of 20 μm using a bar coater to form a resin coating film. Then, the sintering process was performed under the conditions shown in Table 1 to produce a mold release material.

[0113] With respect to the produced mold release materials (No. 1 to 16), a releasability test was performed according to the following procedure, the adhesive strength of the resin coating film (release material) to the printed circuit board was measured, and the releasability of the mold release material was evaluated. The results are shown in Table 1.

Abstract

The invention provides a demoulding material for resin matrix substrate and a method for making the same. When used for manufacturing the resin matrix substrate, the demoulding material is easier to be peeled off from the resin matrix substrate and has excellent stripping performance. The demoulding material for resin matrix substrate of the invention is used for producing the resin matrix substrate. The demoulding material is characterized in that: the demoulding material (1A) comprises an aluminium foil (2) and a resin film (3), with the resin film (3) formed upon one surface or double surfaces of the aluminum foil and composed of an epoxy series resin, a melamine series resin, and a silicone. The bonding strength of the resin film (3) to the resin matrix substrate is 1 to 200g/cm.

Description

technical field [0001] The present invention relates to a release material for a resin-based substrate used when manufacturing a resin-based substrate and a method for producing the same. Background technique [0002] As one of the resin-based substrates, there is a resin-based printed circuit board, and its manufacture is performed as follows. First, glass cloth, paper, etc. are impregnated with a resin, and then dried to form a semi-cured sheet (hereinafter referred to as a prepreg). The prepreg, the copper foil, and the mirror plate made of stainless steel were laminated, and a plurality of laminates thus obtained were stacked, and hot plates were placed above and below the laminates, and pressure was applied. Next, the hot plate and the mirror plate are removed, and the laminate is disassembled to manufacture a resin-based printed circuit board composed of a prepreg after the resin has been cured and a copper foil bonded to the surface. It should be noted that at this ...
