Aero controller board, all soldered up |
Once again, the process of assembly is standard SMT reflow.
Starting with the boards and a pile of parts, apply solder paste on all the pads. Next, place components on the board. I usually inspect under the microscope to check alignment, and here it's crucial to have proper alignment marks on the silkscreen for parts with no visible leads (i.e. the ADXL335 accelerometer, which is a LFCSP package). Stick it in the oven, and let it reflow. This board was easy because all the SMT components are on one side (if it's possible, it's good practice to keep all components on one side to keep assembly easy).
