Production processes are often prone to failures and defects due to heavy manual works which lead to increased production costs and delays. Here, I demonstrate not only an end-to-end automatic visual inspection based on the state-of-the-art object detection algorithms to verify the correct assembly of through-hole technology components on printed circuit boards with live feedback in real-time to avoid slippage of defective products, but also invaluable lessons learned for a successful end-to-end product.
