CEM-3 COPPER CLAD LAMINATES SHEETS

1.Excellent mechanical processability, 2.Punching process applicable 3. Longer drill bit life;

UV Block and AOI compatible, low Z-axis expansion, high thermal delamination, good heat and humidity resistance

With good properties of solder resistance,excellent electrical character,high CTI, mechanical, excellent PTH hole-through, even, good humidity-resistance than paper laminate. CEM-3 can be substitute for FR-4. Widely used in the fields of monitor, switch, supersonic machine, TV, self-ballasted lamp, VCD and DVD equipments, etc.

Usual thickness ranges from 0.6mm to 1.60mmUsual sizes include: 36x48'';40''x 48''; 41''x 49'',  43" x 49"Copper clading: H/0;H/H;1/0;1/1;2/0;2/2Other specification upon requests.
