Through-Hole Inspection

Pre-wave and post-wave.

Before soldering, detect missing, wrong and reversed components, and check pin insertion. After soldering, inspect solder quality at each through-hole pad.

THT pre- and post-wave inspection are DaoAI's (微链道爱) two ACI checkpoints on the through-hole process: before soldering, missing, wrong and reversed parts and lead insertion; after soldering, joint quality on every through-hole pad. The boundary with SMT inspection is process position — leaded parts have a distinct defect set before and after wave soldering. The dedicated machine is the A3.

AI inspection before and after soldering.

Check pin presence and insertion before soldering, then inspect solder quality at each pad after soldering. Dedicated AI algorithms handle these different inspection tasks.

THT pre-wave inspection: enable inspection, generate the program, zoom in on pins and review detected examples

PRE-WAVE

THT post-wave inspection: draw the region, generate inspection windows and review solder joint results

POST-WAVE

Missing, wrong and reversed components.

DaoAI ACI detects missing, wrong and reversed through-hole components with AI. Generate the inspection program from one golden board.

Train for your specific solder joints.

Extend the DaoAI solder model with examples from your own production. Train it to recognize niche defects and acceptable variations in wave, selective or hand-soldered joints.

Collect images from inspected boards

Add individual solder joint images or all matching solder joint images from a product to your training dataset.

Label OK and NG to your standard

Label solder joint images as OK or NG to teach the model your acceptance criteria.

Apply the model where needed

Apply the trained model to selected pads or set it as the default for a component group. It runs alongside the existing joint and bridge checks.

Collect images, label examples, train and evaluate models directly on the DaoAI machine. No internet connection or cloud account required. Model training .
