Market research shows that nearly 80% of the printing process with approx. 64% and from the reflow process with approx. 15%. ERSA, Europe's largest manufacturer of soldering systems, has accepted this SMR challenge and has expanded its product range by screen printers. This consequential step clearly defines ERSA's role as a strategic system supplier taking increased responsibility for the entire SMT processes of printing and reflow.

New Technology
The revolutionary Line Scan Technology (LIST) camera (patent pending) and the TRT (Triple Rail Transport) define the focus of the core competence of this new printer: true savings via optimized parallel processing and 100% post print AOI integrated into the machine.

LIST - Line Scan Technology
Today's printers use a standard camera for alignment and the same camera to rapidly shoot many small field-of view pictures for inspection. ERSA revolutionizes these processes via the use of a line sensor based camera for both alignment and inspection. Unlike commercial scanners, the LIST camera (patent pending) has top and bottom contact image sensors (CIS) and an array of the rod lenses specifically designed for the VERSAPRINT application. Standard cameras take many picture of a very small area, whereby the LIST camera scans entire length of 260mm at a speed of 35mm per second! From an inspection speed standpoint, ERSA's Line Scan technology will wet the new standard. The fastest inspections speed in a printer today is 1,200mm2/s. the LIST camera in the VERSAPRINT achieves the world's fastest inspection speed of 9,100mm2/s! In addition to inspection speed, the scanning of the entire substrate offers many additional advantages.

Parallel Processing: TRT Triple Rail Transport
Optimizing production efficiency remains the foremost goal of SMT equipment manufacturers, cleaning and inspecting. The cleaning process, for example, can be conducted simultaneously or parallel to an inspection process and can achieve a relative cycle time savings. The VERSAPRINT revolutionizes parallel processing based on a TRT Triple Rail Transport and the 100% inspection capability offered by LIST. The two most time consuming processes of printing and inspection can run parallel in order to achieve tremendous cycle time savings!

Print Head: CPC Continuous Pressure Control
Closed loop print pressure control offers the best print results. Weight compensation of print head and squeegee is very easy and fast and is conducted from the front side of printing head.

Intelligent Stencil Cleaner
The intelligent, closed loop stencil wiper automatically starts a cleaning cycle upon the result of the stencil inspection failure. The Gravity Fed Solvent Dispenser ensures exact volume application via monitoring of the cleaning paper. Fast changeover of cleaning paper is possible without using tools. Constant speed control of paperwind assures optimal process stability.

VERSAPRINT Inspection Capability
The revolutionary LIST camera offers advanced inspection capabilities not often found in a printing machine. Detection of paste on pad, detection of print offset, detection of bridges, and finally detection of stencil smearing and lockage can be all managed at line speeds!
