OpenClaw CoWoS Demo

TPU v8 CoWoS Reliability Visualization

This demo translates a CoWoS material-risk simulation into a package-level visual report. The focus pair is TGV Cu Fill against a glass core substrate under a high-power TPU v8 thermal cycle.

Highest concern localizes near high-DNP edge zones where lateral shear accumulates fastest.

OpenClaw Strong Inference: global warpage is not the only threat. The primary failure hypothesis localizes to the package perimeter where DNP is maximal and CTE-driven shear is amplified.

Glass / Interface Findings

TGV Cu Fill: challenging compatibility, score 41.
BT/ABF Organic Substrate: conditional compatibility, score 68.
Primary interpretation: center zones mostly see Z-axis compression, while outer edge zones absorb radial shear and become the first candidate for fatigue or crack initiation.

Why I constantly hit the AI token limit
and why that matters in executive work

I treat AI usage as an operating metric: not because more tokens are always better, but because disciplined experimentation reveals how quickly an organization can turn judgment into systems.

TonyCapm assistant demo Speak

Hello. I am the TonyCapm technical assistant demo, trained to discuss semiconductor QA, SPC and reliability methods, quant research workflows, and CFA-related concepts.

Assistant ready.

I regularly hit the usage limits on my cloud LLM tools, but not because I am automating shallow busywork. I use that budget to test workflows, pressure-check assumptions, and turn expert thinking into repeatable operating systems.

In recent weeks, that meant using AI capacity to:

Architect a self-healing ISO 27001 compliant workflow for my home lab.
Build a local RAG pipeline indexing 8,100+ quantitative and engineering documents.
Simulate CoWoS and glass substrate thermo-mechanical fatigue in Python and R.

In the AI era, a better metric is Return on Tokens: not how many prompts were sent, but how much durable architecture, clarity, and leverage those prompts created.

The QA manager's AI philosophy

My role is not to let AI replace judgment. It is to let AI absorb repetitive analysis so I can spend more time on risk framing, governance, process capability, and the human decisions that still require accountability.

中文摘要

黃仁勳的新 KPI：為什麼我常常把 AI Token 額度刷爆？

我同意把 AI 使用量視為一種生產力訊號，但真正重要的不是消耗了多少 token，而是那些 token 最後有沒有轉化成可靠的系統、流程與決策能力。

我用 AI 做的是 ISO 27001 稽核、RAG 知識庫、以及 CoWoS／玻璃基板模擬等高強度工作。這些不是為了炫技，而是為了把專業判斷轉成可重複、可擴展、可治理的運作模式。

不要只量工時，也不要只量 token。要量的是：這些 token 最後幫你蓋出了什麼。

Strategy One

BTC Fast Trend (EMA 50)

A high-conviction trend model designed for crypto exposure. The framework uses a faster 50-day EMA to react earlier, then sizes positions through volatility targeting to keep risk proportional rather than emotional.

Risk control: Dynamic sizing using rolling volatility.
Signal logic: 50-day EMA crossover for faster participation.
Use case: Designed for investors who prefer process-led exposure over static holding.

Allocation logic

# Risk-On/Risk-Off Rotation (SPY vs KXI)
spy_sma200 <- SMA(prices$SPY, n = 200)
regime <- Lag(ifelse(prices$SPY > spy_sma200, 1, 0))

strat_ret <- (regime * asset_returns$SPY) +
             ((1 - regime) * asset_returns$KXI)

Decision architecture

The public version shows the model shape, while the production-grade tuning stays private.

Strategy Two

Risk-On / Risk-Off Rotation

A defensive macro allocation model that rotates between growth and consumer staples depending on the broader market regime. The goal is steadier participation with more disciplined downside posture.

Mechanism: Shift toward staples when SPY falls below the 200-day moving average.
Objective: Preserve capital in weaker regimes without abandoning upside participation.
Execution: Daily review cycle with lagged signals to avoid look-ahead bias.

Operating Lens

Quant trading with a QA manager's discipline

The strategy framework borrows from semiconductor quality culture: every trade behaves like a managed lot, every shock is treated like process variation, and every drawdown becomes a signal for root-cause thinking rather than panic.
