It sits directly over the hashboard, exposing only the chip surfaces while masking surrounding SMD components — capacitors, resistors, MOSFETs, and signal traces — that would otherwise collect excess paste.

(2) Align stencil over hashboard so each window centers on a BM1489 chip. (3) Apply paste across the stencil with a straight-edge scraper, pressing firmly. (4) Lift stencil straight up to avoid smearing. (5) Inspect each chip for even paste rectangle. (6) Reinstall heatsink, torque mounting screws in cross-pattern.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Which thermal paste do you recommend?\u003c\/strong\u003e\u003cbr\u003eA: For continuous-duty mining on Scrypt at L7's power envelope, a 5+ W\/m·K silicone-based grease (G18 or similar mining-grade) is the right choice. Avoid generic computer-grade paste — insufficient thermal conductivity for sustained ASIC heat flux.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How often should I renew the thermal paste?\u003c\/strong\u003e\u003cbr\u003eA: For continuous mining at 90%+ utilization, plan paste renewal every 12-18 months.
