Abstract
Printed circuit board assembly (PCBA) is the major portion of manufacturing processes of electronic manufacturing services (EMS) industry, where surface mounting technology (SMT) has become the primary assembly method. Two series-connected SMT placement machines in a SMT assembly line are often the bottlenecks due to the unevenly distributed workloads. This paper studies the line balancing of the SMT assembly line focusing on the workload distribution between the two placement machines. A heuristic approach is proposed to reduce the workload difference of the two machines without increasing the total machine setup time. A software, which can be used as an effective automation tool for a company, is then developed based on the heuristic model. This will increase the quality of the service that the company provides to its customers.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
