Quality Gates Along the Line

Every station can add a defect, so good lines inspect between steps. The course shows where to check, what to measure and what to do with the result.

Know the Defects

Most SMT defects look small but come from clear causes in paste, placement or heat. You will learn to spot them and trace them back.

What You Will Learn

A practical path through the SMT process and the quality methods around it.

SMT process overview

The full flow from bare board to soldered assembly and the role of each station.

Paste and stencil printing

Paste behaviour, stencil design and the settings that control print quality.

Placement and reflow

Pick and place accuracy, reflow zones and how profiles affect joints.

Inspection methods

When to use solder paste inspection, automated optical inspection and X-ray.

Defects and root causes

Bridging, tombstoning, insufficient solder, voids and how to fix each one.

Quality metrics

Defect rates, first-pass yield and the standards used to judge a joint.
