Application types
1. Soft substrate to soft substrate lamination
Reel-to-reel/reel-to-sheet, laminating equipment common
2. Soft substrate to hard substrate lamination
Single piece lamination, generally have positioning accuracy requirements, according to the accuracy requirements can use manual lamination
3. Hard substrate to hard substrate lamination
General use of CEF, laminating the most difficult, can not be manually laminated, the need for vacuum laminating machine, roller type laminating machine
