如果请教大神，用Rogers5880压制多层板，板之间用什么材料粘在一起？

请教大神，
0 ^! l1 ~* C; Y+ ~, H1 T9 F8 [8 N9 D如果用Rogers5880压制多层板，板之间用什么材料粘在一起？
材料是什么属性，介电常数等，如果再中间某层金属板刻缝隙，那缝隙的材料是空气、5880还是其它材料，与缝隙大小有关系吗？非常感谢！

是用半固化片粘在一起的。比如RO3001、或者Taconic的HT1.5材料。
缝隙的材料是仍然是半固化片。因为在高温高压下，熔化状态的半固化片被挤进缝隙。

Two categories of adhesive systems, thermoplastic and thermoset, have been used when bonding
