This PCB material, made from FR4 glass fiber laminate and copper clad, is ideal for CNC isolation routing/drilling machines, dry film laminators, screen printed resists, etch resist transfers and ink resist pen.
1/2oz copper clad is typically used in the manufacture of double sided PCB's with Plated Through Holes or Via's. The 1/2 refers to the thickness of the copper foil cladding. Typically 1/2oz board is processed and plated upto 1oz during the manufacture process.
In low current digital applications either 1/2oz or 1oz can be used, for high current or very low resistance applications 1oz is often specified.
We stock standard thickness of PCBs 1.57 mm (1.6mm) - 0.78 mm (0.8mm) and 0.2mm. Our standard board size is 12" x 9", but we can cut boards to any size from the raw 8ft x 4 ft sheet.
The copper clad is based on FR4 (Flame Retardant 4). FR-4 describes the board itself with no copper cladding. Bare FR-4 is yellow/green in colour.
FR-4 has excellent mechanical performance and good performance in dimension thickness.
Copper cladded FR4 board material has an epoxy substrate with glass fiber enforcement, which is compliant with electroplating.
This is a non flammable sheet materiel, however fumes and dust may irritate skin and eyes and inhalation should be avoided to to the fiberglass nature of the sheet.
FR4 PCB material is highly abrasive and requires the use of specialist end mills and drills. PCB Supplies provides the highest of quality tools made of high grade Tungsten Carbide which feature very high cutting performances whilst maintaining the tightest production tolerances.
