Ersa VERSAPRINT
A revolutionary printer with
fully integrated Post Print AOI
Market research shows that nearly
80 % of the defects produced in an
SMT production line result primar-
ily from the printing process with ap-
prox. 64 % and from the reflow pro-
cess with approx. 15 %. Ersa, Europe‘s
largest manufacturer of soldering
systems, has accepted this SMT chal-
lenge and has expanded its product
range by screen printers. This con-
sequential 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 Technol-
ogy (LIST) camera and the TRT (Triple
Rail Transport) define the focus of the
core competence of this new printer:
true time savings via optimized par-
allel processing and 100 % post print
AOI integrated into the machine.
LIST - Line Scan Technology
Today’s printers use a standard cam-
era for alignment and the same cam-
era to rapidly shoot many small field-
of-view pictures for inspection. Ersa
revolutionizes these processes via
the use of a line sensor based cam-
era for both alignment and inspec-
tion. Unlike commercial scanners, the
VERSAPRINT S1
LIST camera has top and bottom con-
tact image sensors (CIS) and an array
of rod lenses specifically designed for
the VERSAPRINT application. Stan-
dard cameras take many pictures of
a very small area, whereby the LIST
camera scans an entire length of
260 mm at a speed of 35 mm per sec-
ond! From an inspection speed stand-
point, Ersa’s Line Scan Technology
will set the new standard. The fast-
est inspection speed in a printer to-
day is 1,200 mm²/s. The LIST cam-
era in the VERSAPRINT achieves the
world’s fastest inspection speed of
9,100 mm²/s! In addition to inspec-
tion speed, the scanning of the en-
tire substrate offers many additional
advantages.
Parallel processing:
TRT Triple Rail Transport
Optimizing production efficiency re-
mains the foremost goal of SMT
equipment manufacturers. In a print-
ing machine, the major process steps
are printing, transporting, cleaning
and inspecting. The printing, for ex-
ample, can be conducted simultane-
ously or parallel to an inspection pro-
cess and can achieve a relative cycle
time savings. The VERSAPRINT revo-
lutionizes 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 a
tremendous cycle time savings!
Print head: CPC Continuous
Pressure Control
Closed loop print pressure control of-
fers the best print results. Weight
compensation of print head and
squeegee realizes low print pres-
sure for highly sensitive applications.
Mounting the squeegee is very easy
and fast and is conducted from the
front side of printing head.
