Press Load and Contact Pressure Guide
Convert press load and nominal contact dimensions into an area and average contact pressure that another team can record. The result is a process-documentation aid, not a prediction of bond strength or local pressure uniformity.
Enter the recorded press inputs
Model: pressure in MPa = load in N ÷ nominal contact area in mm².
Trial record
Nominal contact area5,000 mm²
Average nominal pressure0.2000 MPa
Record tooling geometry, pad compliance and pressure distribution separately.
Interpret the number within the real bond stack
A press can apply the same average pressure while local contact changes because of platen flatness, substrate thickness, cushioning, joint shape or surface roughness. Compare like-for-like specimens and document how load was measured.
