Laminates with Heavy Metal Backing
In the microwave industry many applications require printed circuit boards (PCB's)
being mounted onto thick metal casings mostly for thermal considerations. Taconic's
product range encompasses laminates with heavy metal backing that exhibit superior
adhesion between printed circuit board and metal. The combination of PCB and metal
gives the opportunity to consolidate two assemblies thereby reducing overall
manufacturing costs.
Brass or copper backing is available in thicknesses from 0.8 mm to 6.0 mm, and
aluminium from 1.2mm to 12.0 mm ("metric" thickness grades only). We strongly
recommend a heavy metal thickness of minimum 3 x the dielectric thickness to avoid
bow & twist attributed to "bi-metallic" effects.
All Taconic dielectric grades are available with combined heavy-metal backing and
0.5 oz or 1 oz copper cladding. The largest available panel size is 18x24" (457 x
610 mm), for your convenience supplied burr-free.
