Clean your board. Cut dry film a little larger than your board.\u003c\/p\u003e\u003cp\u003e2. Apply Resist: This Photoresist has 3 layers, the top and bottom layers are clear protective layer, so at the first, you need remove one protective layer, the easy way is to use two small pieces of tape. Then apply the middle layer on board.\u003c\/p\u003e\u003cp\u003e3. Expose: Place your negative artwork over the rest protective layer.\u003c\/p\u003e\u003cp\u003e4. Develop: Remember: you need NEGATIVE film developer, Remove the rest protective layer on the film. After 3 minutes take board out of developer and hold under running water to check,you can always place it back in the developer if needs more time.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEtching:\u003c\/b\u003e\u003cbr\u003eThe dry film is resistant to most of the acid etching solution, the PH value can be resistant to most alkaline etching solution between PH8.0 ~8.5.\u003cbr\u003e\u003cb\u003eCover hole:\u003c\/b\u003e\u003cbr\u003e1.5 mil dry film can fully cover a 0.25 inches thickness hole.\u003cbr\u003e\u003cb\u003ePlating:\u003c\/b\u003e\u003cbr\u003eThe dry film is available in most common use of the plating bath, no wrinkles, no color.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003c\/p\u003e\r\n\u003cp\u003e1 roll photosensitive dry film\u003c\/p\u003e\r\n\u003cp\u003e\u003cb\u003eNote:\u003c\/b\u003e\u003c\/p\u003e\r\n\u003cp\u003eDue to the light and screen setting difference, the item's color may be slightly different from the pictures.\u003cbr\u003ePlease allow slight dimension difference due to different manual measurement.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\r\n","brand":"UNIQBUY","offers":[{"title":"Default Title","offer_id":50750850531614,"sku":"60006181","price":916.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/9266\/7678\/files\/60006181_1_image.jpg?v=1775855965","url":"https:\/\/uniqbuy.in\/products\/30cmx1m-photosensitive-dry-film-for-pcb-circuit-production-photoresist-sheet","provider":"UNIQBUY","version":"1.0","type":"link"}
