We use DL Designs for all our PCB Layout needs, ranging from simple, single sided, single layer boards to complex, high density, 10-layer boards with high speed, length matched differential pairs and they have never failed to impress.
DL Designs are highly skilled, flexible, easy to get on with and have a very structured and efficient way of working and communicating with their customers. I cannot think of a single board that has had an issue due to their wrong doing which is remarkable.
Placements and layouts are always neat and completed in a timely manner. We are a long term customer with our relationship extending back for over 8 years. Highly recommended, we wouldn’t use anybody else.
