The Mercurex lineup includes two models: the highthroughput LI-9000 and the high-precision LI-9500.
The Mercurex is a multi-purpose direct imaging system designed for various exposure processes of printed circuit boards, such as inner layer, outer layer, and solder resist patterns.
The combination of a SLM (spacial light modulator) and Screen's exclusive optical technology enables the use of an ultra-high-pressure mercury lamp as the light source.
Conventional resists used for one-shot exposures can even be used with the new unit.
Circuit patterns can be exposed on to the resists directly from CAD data without the use of a photomask, resulting in drastically improved turn around times and reduced costs.
Naturally the problems associated with using a mask are totally eliminated.
Screen's highly advanced imaging head achieves a minimum width of 15µm L/S and an accuracy of ±1µm.
Scaling features have been implemented to match expansion and fluctuations in the board, while the autocalibration feature brings about a positioning accuracy of 10µm (3σ).
The unit is ideal for exposing across a range of applications, including multi-layer boards, packages, and build-up PCBs with intricate patterns.

The relentless miniaturization and sophistication of electronic devices such as palmtop computers and portable phones has accelerated the miniaturization of circuit board patterns. As a result, inspection systems with higher performance and reliability are now a necessity.
The PI-8700 can inspect a variety of boards, such as outer layer/inner layer/mixed circuit boards, as well as BGA and CSP package boards, at high speed and with high precision. It is a high-end optical inspection system that offers excellent operability.

The WI-8000 is a visual inspection system designed to detect the fine defects that occur on work-size substrates during intermediate processes. This system features the leading color inspection technology developed for Screen’s FP-8000 series of final visual inspection equipment.
The WI-8000 quickly locates structural failures such as solder-resist stripping around silkscreen and solder adhered to minute areas of solder-resist stripping, which are difficult to detect and correct in the final process. This technology makes a major contribution to improving yield rates.

The VT-2000 is a defect verification and repair system that displays defect data for boards on a monitor, with the aid of inspection data from SCREEN AOI systems.
When the operator places an inspected board on the verification table and enters the board's lot number, the camera automatically moves to the locations of defects on that board, and displays enlarged images of the defect areas on the monitor. The monitor's attachment position has been adjusted to lower the viewing angle, which reduces the strain on the operator during verification.
