Choosing the Correct Foil - When using transparent glass or bevels, choose your foil based on the color of your solder seams:
Choosing the Correct Foil thickness
1mil - Thinnest of the copper foil tapes. Recommended for the price and ease of folding. Higher potential to tear than a thicker tape. Most popular.
1.25 mil - This mid-price range and mid-thickness tape offers an increased strength factor. Second most popular.
1.5 mil - Thickest available tape. Suitable for applications where the tape is splitting during application. Least popular thickness. Edco does not manufacture a 1.5 thickness.
