Thermal performance, adhesion strength and visual inspection were used as pass/fail criteria. ## **Apparatus** Anatek[®] Thermal Analyzer: The ATA was used to measure Rj-a before and after environmental stressing. PQFP: 196 lead, plastic PQFPs known to contain silicone mold release were evaluated. T-WING Heat Spreader: 1 in x 4 in T-WING parts were applied to the PQFP packages with a 5 psi (0.03 MPa) mounting pressure. - Light weight (0.039 oz/in[2] ) - Standard parts are scored for easy forming and alignment - Easy removal for device replacement - Available die-cut on continuous rolls **Phone +1 781-935-4850 www.parker.com/chomerics** 1 ## **THERMAL PERFORMANCE** Various sizes of T-WING heat spreaders were applied to a 196 lead PQFP using less than 5 psi (0.03 MPa) bonding pressure. Within 30 minutes of application, the test boards were mounted in an Analysis Tech[®] thermal analyzer. The devices were heated to equilibrium (45 to 60 minutes) with approximately 3 watt load on 3 x 3 in (7.6 x 7.6 cm) test boards. Two test environments were used: restricted convention, achieved with a 1 x 5 x 6 in (2.5 x 12.7 x 15.2 cm) plexiglass box; and 100 LFM (30 m/ min) air flow. Results were obtained using thermocouples for Tc (centered on case) and Rj-a. ## **Environmental Stressing** Control: Specimens were maintained for 1000 hours at standard laboratory conditions, 23°C, 35-60% RH. Heat Aging: Test specimens were placed in a forced convection hot air oven maintained at 150°C ±5°C for 1000 hours. Test specimens were then removed and tested. ## Elevated Temperature/ High Humidity: Specimens were placed in a humidity chamber maintained at 85°C ± 2°C and 90%-0 +10% RH for 1000 hours. Temperature Cycling: Specimens were subjected to 500 cycles from -50°C to +150°C in a Tenney Temperature Cycling Oven. Temperature Shock: Specimens were subjected to 100 temperature shocks by immersion into -50° and +150°C liquids. Temperatures were monitored with thermocouples. ## **Evaluation Procedure** Visual: All test specimens were examined for de-bonding, delamination or other signs that the tape was failing after environmental stress. Thermal Performance: T-WING was applied to the PQFP with 5 psi mounting pressure. After a one hour dwell, the Rj-a of each specimen was measured at 100 LFM and under restricted convection conditions. The Rj-a was again measured after environmental stressing. 90° Peel Strength: A T-WING heat spreader was applied to each PQFP with 5 psi mounting pressure. The specimens were subjected to environmental stress and then tested for 90° peel strength at room temperature. ## **Results** Visual: There was no visual evidence of T-WING adhesion failure to the PQFP after the environmental stresses. Thermal Performance: The before and after thermal resistances are given in Table 4. The data shows that the thermal resistances were essentially unchanged by the exposures. 90° Peel Strength: The results of the peel strength tests are given above. The data shows that the average peel strength actually increases with high temperature/humidity and temperature shock, while remaining unchanged with heat aging and decreasing slightly with temperature cycling. ## **APPLICATION INSTRUCTIONS** **Materials needed:** Clean cotton cloth or rag, industrial solvent, rubber gloves. **Step 1:** For best results, clean the top surface of the component using a lint-free cotton cloth. **Step 2:** Wipe the bonding surface of the component with an industrial solvent, such as MEK, acetone or isopropyl alcohol. In the case of a plastic package, select a cleaner that will not chemically attack the plastic substrate. Do not touch the cleaned surface during any part of the assembly process. If the surface has been contaminated, repeat Steps 1 and 2. **Step 3:** Remove the clear release liner from the T-WING part, exposing the pressure-sensitive adhesive (PSA). Avoid touching exposed adhesive with fingers. **Step 4:** For best bond strength and contact area, center the exposed PSA onto the component. Press and smooth the entire T-WING bonding area with firm finger pressure of about 5 psi, for 5 seconds. Note: Bond strength will increase as a function of time as the adhesive continues to wet out the bonding surface. Increasing any of the application variables (pressure, temperature and time) can improve bonding results. **Phone +1 781-935-4850 www.parker.com/chomerics** 2 ## **T-WING[®] Heat Spreaders** **==> picture [394 x 272] intentionally omitted <==** **----- Start of picture text -----**
