Following the successful introduction of ViCON for Rehm’s

reflow convection soldering systems, the software has

now been specially adapted to the requirements of the

ProtectoXP and ProtectoXC dispensing systems. The main

feature of ViCON Protecto is the option of importing ECAD

data and image les directly and optimising ECAD data for

the coating process by cutting. The integrated camera also

enables stitching: A complete image of the printed circuit

board can be created and further processed from several

individual images. While the program is being created, the

user is supported by a wizard that shows the user all current

progress by means of colour-coded pointers, and thus easily

facilitates usability.

After selecting an applicator, users can access a coating

database via ViCON Protecto that has been lled by the

application specialists of Rehm Thermal Systems and

contains all the important coatings with their parameters.

ViCON Protecto enables programs to be created offline,

which can be used simultaneously with the current produc-

tion process. With the camera integrated into the Protecto

coating systems, ViCON software can be used to read both

ducials as well as (data matrix) codes (DMC).

The objective of ViCON Protecto is to congure the system’s

current operating status clearly. The operator can react

quickly and intuitively to status and alarm messages. At the

same time, access rights, views and favourites are tailored

to each user. The specications of ViCON Protecto are

based on the basic elements of ViCON, which have already

performed impressively in the convection soldering systems

of the Vision series. Thanks to colour coding, the operator

can also easily identify and assign the status of the display

from a greater distance. ViCON software is also consistently

designed to accommodate multiple languages. The simplic-

ity with which you can switch “on the fly” to the preferred

language simplies worldwide remote access to other Rehm

systems and operating in an international environment.

Alarm messages can be clearly viewed, interpreted, edited

and processed at the top of the screen – the relevance of

the alarms is displayed in different colours. To control the

system individually, the operator can individually create a

favourites bar, that includes relevant and necessary param-

eters and control elements. These then appear on the main

screen and at a denite point on each page.

The ViCON Protecto enables guided coating program creation by using a wizard.

Process locking, traceability & co.

for a detailed process documentation

Depending on the production environment, the Protecto

systems can be optionally connected to an MES in various

ways. Any combination of the various conguration stages

of production data acquisition (PDA), traceability, process

locking and material locking ensures flexible production.

The Protecto systems can be optionally connected to a

line master computer or an MES. Depending on the cong-

uration, various data is communicated between MES and

ProtectoXP/XC. An interface specially designed by Rehm

(ROI – Rehm Open Interface) is used. On the one hand, this

means a high degree of standardisation; on the other hand,

customer-specic adaptation can be carried out without

problems. To identify the module, an ID-reader (bar code,

DMC, RFID) is installed on the conveyor belt in front of the

system and connected to the Protecto control. Optionally,

the identication can also be carried out via the MES. This

ensures absolute process reliability through process locking

and can guarantee seamless documentation by means of

unique data records for each module.

Optimum assembly protection

without contamination of the work environment

To prevent contamination from vaporised sol-

vents of lacquers and compounds in the immedi-

ate vicinity of the Protecto systems, the lacquer

supply is integrated in the system at the back

of the plant (XP) or at the front of the machine

(XC). This means there is no odour pollution from

random releases of solvent vapours into the envi-

ronment. The plant also has an extractor system

which conducts and removes solvent-containing

evaporations to the in-house exhaust system

during the coating process.

Rehm has developed a ground-breaking cleaning sys-

tem for Protecto systems which is particularly mainte-

nance-friendly. A brush station with a solvent bath allows

optimum cleaning of the lacquer nozzles. Even if the sys-

tem has been off for up several days – depending on the

used material – it is operational at the touch of a button

without additional cleaning work. The cleaning tank pro-

tects nozzles, cables, connections and ports from drying

out and automatically cleans the system during downtime,

without wasting resources. This allows long processes to

run without requiring maintenance. Depending on the ma-

terials even long downtimes without cleaning and flushing

the valves or system are possible. All control elements and

lacquer stocks are easy to access for the performance of

maintenance tasks.
