Abstract: A metal substrate includes a first insulating substrate, a second insulating substrate, a first metal layer, a second metal layer and a release layer. The first insulating substrate has a first modified surface and a second surface opposite to the first modified surface. The first metal layer faces the second surface. The release layer is bonded on the first modified surface. The second insulating substrate is bonded on a side of the release layer, such that the release layer is between the first modified surface and the second insulating substrate. The second metal layer is disposed on a side of the second insulating substrate, such that the second insulating substrate is between the release layer and the second metal layer. An original surface roughness of the first modified surface has a variation substantially less than 10% after the first modified surface is released from the release layer.

Abstract: A method for manufacturing a liquid crystal polymer film includes the following operations. Liquid crystal oligomers are received, in which the liquid crystal oligomers have a melting point of Tm1 and has an average degree of polymerization of 10 to 100. A first heating process is performed to melt the liquid crystal oligomers, in which the first heating process has a first heating temperature higher than the Tm1. An extrusion process is performed to make the liquid crystal oligomers into a first film. A second heating process with a second heating temperature is performed to heat the first film, in which the liquid crystal oligomers in the first film are polymerized to form a second film including liquid crystal polymers.

Abstract: A multilayer board includes laminates. Each of the laminates includes a liquid crystal polymer substrate and a metal layer. Each of the liquid crystal polymer substrates has a melting point. When a number of the liquid crystal polymer substrates is an odd number, they include a first middle substrate that is located in the most middle position and has a first melting point lowest among the melting points. The melting points increase in a direction away from the first middle substrate. When the number of the liquid crystal polymer substrates is an even number, they include second and third middle substrates that are located in the most middle position and respectively have second and third melting points that are substantially same. The second or third melting point is lowest among the melting points. The melting points increase in a direction away from the second and third middle substrates.
