Lloyd Doyle design, manufacture and market sophisticated automatic optical test (AOT) systems used in the bare board sector of the printed circuit board manufacturing industry. Founded in 1982, they have maintained a solid growth pattern throughout the last decade and now supply their equipment to many of the worlds leading pcb manufacturers.

Lloyd Doyle is based in Surrey, UK where the research and development, design, manufacturing and after sales support is managed. At this location the company employs leading industry scientists, dedicated design teams and support personnel in addition to the company administration staff. Further Lloyd Doyle facilities placed strategically at the heart of the pcb manufacturing centers around the world provide support, demonstration and sales on a local basis.

Lloyd Doyle was founded by Roy Lloyd and Dr Keith Doyle in 1982 to supply industrial automation products with an optical and electronic bias. The first products applicable to pcb fault detection were brought to the market in 1986 as TRACKSCAN; reflective light based optical test systems.

Development of these products over the next 8 years brought the TRACKSCAN 4000 model to the market which provided state of the art optical test for the pcb manufacturing industry.

A step change in technology in 1994 gave rise to the EXCALIBUR range of systems which brought higher scan speeds at the same time as higher resolution, and opened up the high-volume sector of the market to Lloyd Doyle. EXCALIBUR has been continually developed and today provides the most cost effective way of finding faults on pcb layers.

Recent developments in 2000 saw the release of phasor, which is the first laser/ccd based AOT system. phasor combines laser illumination and the florescent properties of pcb laminates with new style ccd cameras to give unbeatable performance on low contrast pcb laminates.

A range of repair stations complement the range of test systems to give maximum flexibility.

EXCALIBUR and phasor products provide for mainstream optical test applications, but they also specialise for niche markets providing options to scan large formats, HDI products with fully automatic panel handling.
