Engineering
Five stages from a drawing to repeat production. Each stage has a defined deliverable and a defined input from your side.
Direct answer
No stage starts until the previous deliverable is agreed. That is what keeps a custom project from drifting.
| Step | Deliverable | What you prepare |
|---|---|---|
| 01 · Requirements sheet | A one-page specification we both sign off: heated area, voltage, power, target temperature, environment, volume. | Product drawing, supply voltage, target temperature, expected annual volume. |
| 02 · Design and thermal simulation | Film outline, conductive pattern, resistance target and a predicted temperature profile. | Confirmation of the mounting surface, insulation and any constraints on the heated area. |
| 03 · Sampling | A physical sample built to the agreed drawing, with leads and connector as specified. | A receiving address and a named person to evaluate the sample. |
| 04 · Testing | Measurement against the agreed acceptance criteria, with the method and conditions recorded. | Agreement on acceptance criteria before the test, so the result is not negotiable afterwards. |
| 05 · Mass production | Repeat parts with the agreed inspection record, released from the production line. | Purchase order, delivery schedule and any incoming-inspection requirements. |
Samples are typically ready in about 1 week from an agreed drawing. Custom quote per project · MOQ 5 pcs
Before you start
Four inputs decide whether a project takes one week or one quarter.
Even a sketch with dimensions beats a description.
Voltage and available current, not a range you hope to narrow later.
Steady-state target and the time allowed to reach it.
What counts as a pass, agreed before the sample is measured.
Where the numbers come from
Film-level data comes from a third-party report. Panel-level data comes from a measured grid. Both are published with their limits.
Send the drawing, supply voltage, target temperature and expected volume. We will come back with a specification and a project-specific quote.
