How video cards are made

A good video card is a window and an entrance ticket to the world of exciting content. But few people know how video cards are made. In this material, we propose to arrange a virtual tour of the production and see how they are made.

A little about production
A video card manufacturing plant is a huge enterprise that performs the final assembly of video adapters from ready-made components. Production is a rather long pipeline, where people and robots work side by side with each other. The machines are entrusted with routine, but high-precision work. People are mainly involved in the stages of control and testing of finished products. Also, people perform the functions of servicing the robotic fleet and other devices involved in the production process.

All components for assembling video cards come to the enterprise from third-party manufacturers.

GPUs – from developers, Nvidia and AMD, who are the “trendsetters” in the world of discrete graphics.
Memory chips are from reputable manufacturers, whose products correspond to the type and configuration provided for by the reference design of the graphics card developer.
Printed circuit boards – from third-party manufacturers.
Independent production of printed circuit boards is a rather complicated and costly undertaking. The printed circuit board of a modern card can contain from 10 to 14 layers. This requires from the manufacturer a large amount of high-precision equipment and a staff of qualified personnel. In other words, the manufacture of printed circuit boards is a separate large production. Therefore, it is economically feasible to order the production of boards from third-party manufacturers.

Electronic components (resistors, capacitors, diodes, chokes, etc.) also come to the enterprise from third-party manufacturers.
After the necessary components are put on the conveyor, the production process of the graphics adapter begins. It consists of several stages, sequentially following each other.

Mounting components
As a rule, most of the electronic components are mounted on the board using SMT surface mount technology (from the English. Surface mount technology ). To do this, the printed circuit board is prepared for mounting SMD components (from the English. Surface Mounted Device – a surface-mounted device). The board is placed in a machine that applies solder paste to its pads using a stencil specially designed for that board configuration.

After applying the paste, the printed circuit board goes through a series of robotic machines, the mechanical manipulators of which place all the necessary electronic components on it: from resistors and capacitors to memory chips and a graphics processor.

The miniature components are fed into the machine using tapes wound into reels.

Large elements – are located on movable tables, from where they are taken by the “hand” of the manipulator and placed on the board.

The mounting speed is five to ten elements per second. Positioning accuracy is controlled by laser and optical sensors.

First of all, the installation is carried out from the back side of the video adapter board, after that – from the front side of the printed circuit board. Memory modules and GPU are installed last.

Soldering components
After installing the parts on one side of the board, it moves to a special induction or infrared furnace, in which the board is heated, the solder paste is melted and the electronic components are fixed on the printed circuit board.

In order not to spoil the temperature of the “delicate” electronics, the board is heated in several stages. During the movement of the board along the conveyor of the furnace, it passes about ten temperature zones. During soldering, the temperature in the oven ranges from 175°C to 245°C. This is necessary so that the board and electronic components first warm up evenly (up to about 195-200 ° C), and then the solder paste melts (t ≈ 245 ° C). After that, the board cools down.

The same mounting and soldering processes are repeated on the second side of the printed circuit board.
