RF & Microwave Laminates with Heavy Metal Backing
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, copper and aluminium backing is available in thicknesses from 0.5 mm to 6.35 mm (0.02" - 1/4"), with "metric" thicknesses being the main grades.

All Taconic dielectric grades are available with combined heavy-metal backing and
0.5 oz or 1 oz ED and RA copper cladding. Typical panel sizes are 12x18" (304 x
457 mm), for your convenience supplied burr-free and with rounded corners. A low-tack protective film ensures a defect-free surface
For power amplifier applications RF-35P and RF-60A are the main laminate grades, whereas TLX and TLY are mainly used for radio links.
