A unique for the Russian Federation assembly line with automatic 3D inspection appeared near Kaliningrad

Kaliningrad Digital Television Systems (DTS) factory has redesigned a line for surface mounting of electronic components on the board so that now it has additional functions, namely: automatic 3D inspection of the solder paste and dual automatic optical 3D inspection before and after soldering.

A total of 25 million rubles was invested in modernization.

The company said that now leading manufacturers of computer and peripheral equipment impose high requirements to the quality of their products. Using of control equipment after all critical operations is now obligatory; its absence, on the contrary, serves as a blocking factor for customers.

As it follows from research of German manufacturer of equipment for electronic components assembly and surface mounting ASM Assembly Systems GmbH, 2/3 of all defects are caused by quality of solder paste application. Monitoring the stability and repeatability of this process is therefore fundamental.

3D optical inspection starts immediately after installing the components and before the board is fed into the fusion furnace. This gives possibility to control how accurately components are set before soldering and to make corrections without board repair.

It is especially important in case of production of expensive or complicated for repair components like processors or chips.

Because the board is not in place during inspection, it is not possible to move unsoldered elements.
