產品介紹 - 無鹵覆蓋膜(黃色、黑色)

Product introduction- Halogen free coverlay (yellow / black)
黃色、黑色無鹵覆蓋膜(CVL)是由聚酰亞胺薄膜塗覆高性能熱固性環氧樹脂接著劑,以離型紙做隔離層,經高溫固化後形成的絕緣耐熱膠膜。材料廣泛應用於FPC製造,以作線路保護及絕緣層。

Halogen free coverlay (CVL) is a kind of high temperature thermosetting epoxy resin coated with polyimide film. Then, the insulating coating is made of release paper as insulation layer and cured by high temperature. The series of materials are widely used in FPC manufacturing for line protection and insulation.
