How to inspect circuit boards and solder joints with computer vision

How can an electronics maker use computer vision to check assembled circuit boards?

Train a model on the plant own board images so it can mark likely missing or shifted parts, parts placed the wrong way round, solder bridges, too little or too much solder, and lifted leads. Each mark points to the board, side and spot on the board, so a trained inspector can look closely and decide whether to pass, rework or scrap it. The model only highlights boards and spots worth a second look; it never passes a board on its own, and the existing test and quality steps stay in place.

What this means in practice

Collect images of boards that inspectors have already passed or failed, on each product and line
Label the defect types the quality team tracks, plus good examples of each part type
Run new board images through the model and send only marked boards and spots to the inspector
Have a trained inspector confirm or reject each mark and record the rework decision
Add confirmed and rejected marks back into training whenever a new board design or part comes in

How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
