In an exemplary implementation, a system for producing an electrical module includes a pressure chamber configured to receive a first body, a second body, and a sinter material therebetween. The system further includes a pressure generator configured to apply non-mechanical pressure in the pressure chamber to form the electrical module by attaching the first body to the second body using the sinter material. The pressure chamber is configured to enclose the first body over the second body. Furthermore, the pressure chamber includes a bottom opening configured to receive at least the first body. The non-mechanical pressure can include gas pressure.
