Controlled Bonding Trial Matrix
Build a seven-condition, one-factor-at-a-time sequence around one baseline. The matrix helps identify which control direction changes the result; it does not establish a universal production setting.
Define the baseline and step size
Hold material lot, substrate preparation, construction, cooling and verification method constant.

Use the matrix as a diagnostic sequence
Do not change adhesive grade, surface preparation or cooling method inside this sequence. If the safe equipment or material range cannot accommodate a step, reduce it before running specimens and record that decision.
