Overview

MINCO HK6904 Polyimide Thermofoil heaters are flexible heaters bonded using an acrylic pressure-sensitive adhesive (PSA).

Handling

DO:

Wear gloves when handling component to prevent contamination of heater and adhesive.
Clean the application area using a suitable solvent such as acetone or alcohol.
Avoid trapping air within the adhesive during the mounting procedure:
- Apply the heater starting from a corner edge, using firm and even hand pressure.
- Peel off release liner slowly, while applying firm pressure outward to the unadhered sections to avoid trapping air.
- If necessary, use a rubber roller to press the heater into place and remove any trapped air. This step should be repeated after the heater is baked in a vacuum chamber, to maximize adhesion.

DO NOT:

Touch exposed PSA once the release liner is peeled off.
Cut the perimeter or surface of the heater, and its lead wires. replacement of the heater will likely be necessary if this occurs.
Partial PSA removal and reapplication is not recommended.

Heater should be stored in a temperature and humidity controlled environment (16C/60F to 27C/80F & 40-60 RH%) for a maximum of 60 months (5 yr) to maintain adhesive quality.
Storage environment should limit UV exposure (sunlight)
Special storage is no longer needed once heaters are bonded to heat sink
