Reflow soldering is a technique used to connect very small electrical components together using a soldering paste and heat. Marc, an electrical engineering student, and Erica, a medical physics student, spent the afternoon reflow soldering small transceivers that are smaller than 1cm x 1cm in size. These transceivers will be used to communicate with the satellite.
