Challenges
The existing proof of concept electronic design used many PCBs and connecting wires to control the electro-mechanical equipment within the unit. These PCBs also had to be manually tuned which was both time consuming and produced inconsistent results. This resulted in a high cost of manufacture along with reliability issues.
Solution
Our solution was to replace all of the PCBs with a single microprocessor controlled PCB. This allowed us to keep the manufacturing cost low while also allowing automatic calibration, self test diagnostics and functionality updates in the field.
Benefits
Our solution provided a cost effective design, both in terms of bill of materials and manufacturing time. It also made fault diagnosis easier and allowed firmware updates in the field to enhance functionality.
