Application Notes for IGBT modules were updated

10 September 2024

We are glad to inform that Application Notes were updated to product pages for all IGBT modules made by Proton-Electrotex.

Proton-Electrotex, JSC employs modern technologies used by many global manufacturers. The first step in manufacturing IGBT modules is soldering. Soldered seam provides mechanical connection between module components, as well as electrical and heat conductivity.

The soldering process at Proton-Electrotex, JSC is based on a modern method of conductive heating in vacuum in vapor of formic acid using preforms. Such approach improves mechanical life and reliability of the devices thanks to the following:

single pass soldering reduces heat stress in the components;

a large selection of available soldering alloys, including various materials with required elasticity and melting temperature;

cleaner preforms as compared to paste;

no need for subsequent wet cleaning;

high quality of soldered seams thanks to the vacuum resulting in minimal amount of caverns and voids;

high thermal capacity components – the baseplate and DBC – are heated first. Chips are heated last, reducing influence of high temperatures on the chip;

very flexible customization of soldering temperature profile – an important feature for lead-free technologies;

voids area <3%

The next step is ultrasonic welding with aluminum wire and welding power terminals and connections. Ultrasonic welding of power terminals, control terminals and chip connections is a new modern technological approach to manufacturing classic IGBT modules.

The high technology ultrasonic welding allows Proton-Electrotex to produce high quality devices on par with world leaders of the semiconductor industry. Thanks to the ultrasonic welding, service life of modules is no longer limited by reliability of contact connections of a conductor inside the device.

IGBT modules are manufactured by Proton-Electrotex are successful used in AC motor drives, voltage inverters for solar panels, wind turbine inverters, railway traction drives, high power converters and UPS, power transmission and distribution grids etc.

The Application Notes contain a detailed description of the structure and design of IGBT modules, features of various operating modes and recommendations on related items necessary for the operation of the device.
