Assembly and mounting in housing.
Distinctive features of our surface-mounted assembly line:
installation of chips from 0402, integrated microcircuits with interval from 0.4 mm;
quick changeover from one board to another is provided by advanced construction of power supply sources with bar code identification (Agilis feeders);
a new printed board could be programmed without stopping the production line;
automated accounting system of stored components and their consumption during assembling;
along with a standard optical alignment camera a specialized camera of higher resolution is available that enables to install performance components (integrated microcircuits in housings with small output interval and BGA);
Printed circuit boards with dimensions up to 20x20 mm or boards without specific processing edges could be applied;
For high performance orders a verifier of mounted components’ electrical parameters could be installed.
Solder paste is applied by means of a screen printer of TWS Automation production (Italy).
components are mounted on surface of a board by My9 pick and place machine of MYDATA Automation production (Sweden) which is significant for its high capacity and accuracy of components placement.
Welding of surface mount components is provided by a convection soldering system of SEHO Seitz & Hohnerlein Gmbh production (Germany) which is equipped with four heating zones.
Washing of printed-component assemblies is carried out in ultrasonic bathes of Reltek production with usage of special washing liquids.
Visual control of components mounting is provided by stereo microscopes Mantis Elite.
Temperature tests of electronic modules are carried out Tabai Thermal Shock Chambers with usage of our own control equipment.
