Kinsten manufacture the positive resist coated printed circuit board (PCB) for many prototyping, educational and low volume applications. Even some high volume applications have used Kinsten PCB to keep the full process secure and in-house.
Fibreglass is the most commonly seen PCB substrate. These Singe Sided PCBs have good electrical and physical characteristics, being robust with good di-electric strength. Kinsten supply it with 1oz or 2oz copper cladding (selected sizes). Fibreglass substrate is generally a straw yellow to green colour, and is available in thicknesses from 0.6mm to 1.6mm
The positive resist has good exposure latitude and can produce very detailed track layouts when suitable artwork and processing is used.
Fibreglass is more demanding to cut and drill. PCB shears are recommended to cut fiber-glass PCB, and carbide drill bits are recommended for drilling.
