After plating-through-hole, dry film will be laminated on pretreated boards as etching resist.
Dry films are kinds of photosensitive film, so the operation have to be proceeded in a yellow light clean room for preventing side reaction.FPC mass production might use reel-to-reel mode. This film laminating operation is different from sheet by sheet mode and need different laminator.
貼膜：鍍通孔後，以熱滾輪加壓貼合，在清潔完成的材料表面貼合一層乾膜(dry film)作為蝕刻阻劑。乾膜對光線中的紫外線敏感，因此必須在黃光室作業，避免乾膜在製作前就發生變化。軟性電路板在大量生產模式中，常會使用捲對捲生產方式，所以貼膜作業所使用的設備與一般單片操作設備略有不同。
