The oven followed a temperature profile that facilitated efficient soldering with minimum "tomb-stoning" components
The final project of my PCB Design course (ESE 292) was to create a WiFi-controlled robot for a "jousting" competition. I designed both custom PCBs to house the micro-controller and the motor-controller for the robot, using Altium.
The PCBs were fabricated in China, but I picked and placed the components onto the boards manually. Larger components, such as header pins and connectors were hand-soldered, whereas smaller components (ICs, resistors, etc.) were reflow-soldered in an oven.
