Macrofab Engineering Podcast

In this episode of Circuit Break, hosts Parker Dillmann and Stephen Kraig dive into the nuances of working with contract manufacturers, specifically focusing on the responsibilities of both the designer and the manufacturer. They discuss critical topics such as reflow profiles, solder specifications, parts washing, and the benefits of allowing your CM to handle PCB panelization. Parker also shares updates on his personal project, the PropFan controller, detailing its features and the challenges faced during its development.Key Discussion Points:What information can you assume your CM will handle?Reflow profile considerationsSolder specifications and BGAsParts washing requirementsPanelizing PCBs: Why it's best left to your CMPersonal Project Updates: PropFan controllerSwitching to a SamD21 MCU for the PropFanUsing the LT8672 for circuit protectionDetails on the Crystal Fontz CFA533-TFH-KC displayImplementing I2C to differential pair conversion with PCA9615Using Ethernet to connect the display and PWM controlle
