1. Substrate and process window data
Start with the workpiece itself. Record the panel size and thickness, the substrate type (glass, or flexible film where a vacuum laminating machine is used), and the film stack you intend to bond. PowerDe's large-size automatic laminating machine is specified for high-precision bonding of large LCDs, and other models in the same semiconductor process equipment line cover medium-size film application in the 10–32 inch range, curved-surface bonding for flexible OLED, and aluminium plate plus LCD bonding in the 60–86 inch range. Note which model your size falls into, and keep the material data with the trial results.
2. Alignment and registration data
CCD alignment and roller bonding appear repeatedly across these machines, but alignment accuracy is only meaningful when you know how it was measured. Collect: offset readings per corner, the alignment method, and — most important — how the readings change from the first panel of a run to the last. On a large substrate a small drift per cycle becomes a visible defect at the edge. Ask for the alignment data set as a run of consecutive panels, not one representative shot.
3. Bond quality and defect data
For laminating, the defect list is short but must be counted: bubbles, dust inclusions, wrinkles, incomplete wetting at the perimeter, and shift after release. Record defect counts by zone (centre, edges, corners), by panel, and by shift. Debubbling results belong in the same data set — a high-pressure debubbling machine is often the recovery step, and you need to know how many panels actually require it.
4. Vacuum, temperature and pressure curves
Log the actual process curves, not just set points: chamber pressure before and during bonding, heating behaviour, and pressure applied by the roller or platen. Where a model's listing states working vacuum or press pressure, treat those numbers as the boundary of the process window and verify them on your own product. Temperature uniformity across a large area is worth measuring separately; a curve logged at the chamber sensor does not prove the panel centre is at the same temperature.
5. Cycle time and throughput at your size
Cycle time quoted on a small test piece will not carry over. Time the complete operation — load, alignment, bond, unload — at your panel size and your film, and separate machine time from handling time. Where an equipment listing gives a cycle time, check what size and test condition it was measured on before using it in a capacity plan.
6. Uptime, yield and rework
Track first-pass yield, alarms and stoppages, time to recover, and consumable use. Machine availability figures are useful acceptance data only when you also hold the yield data, because a machine that runs continuously and produces rejects is not available in any sense that matters to production.
7. Changeover and recipe data
If you run more than one panel size, record how long a changeover takes and what changes with it: fixtures, program parameters, recipe selection. Some PowerDe equipment is described with selectable recipes to control alignment and bubbles; on a multi-product line, how fast and reliably you can switch recipes is part of the machine's real capacity.
How to collect this data with the supplier
Two practical points decide whether this data is worth anything. First, run the trial on your own panels and your own film, not on the supplier's sample stock. Second, have PowerDe's engineering team walk through the trial plan and the parameter records before you agree to it — their hardware testing and custom equipment services are built around exactly this kind of verification, and the record from a trial agreed in advance is the document you use at acceptance.
Send us your panel size, film stack and target output, and we will tell you which machine in the large-size range applies and what data the test report should contain. Contact details are on the contact page.
