Really corresponding positioning, vacuumizes in a device, and ultra-thin glass surface layer (1) and substrate (4) is leaned on adosculation, carries out vacuum pressed patch
It closes, so that LOCA glue sufficiently extends and fills full ultra-thin glass surface layer (1) and substrate (4) gap.
Step 4: the product after fitting is put into UV curing oven, in 50-70oC temperature range, penetrates ultra-thin glass with UV light source
Glass surface carries out hardening with radiation to LOCA, and cured UV intensity is adjusted to guarantee that solidification is filled according to the thickness of LOCA glue film
Point, good fit, transparent light wear-resistant fire retardant, multi-layer composite material required for being obtained after solidification.
