Kinsten GS

GS selection table

Low cost, robust

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. It has 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 0.2mm to 1.6mm

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.

There have been significant changes to freight transport.

Notably, most services reject chemicals (DP50 developer & EB750 etchant) as general cargo or for post. They have to be sent as Dangerous Goods. We don't offer this service.

While the situation is improving, some orders experience longer than quoted delivery times. This is outside of our control.

EMS Courier

Where available, EMS delivery is generally 3 to 7 days from despatch, but some countries will take longer due to incoming customs delays. Tracking is available for all EMS deliveries.

International Parcel Post

Parcel post can be used when delivery time is not critical, at a lower cost.

Air Post delivery time can vary from 7 days to 45 days from despatch, but is typically delivered within 30 days.
