Taiwan's ASE Technology, the world's biggest chip packaging and testing company, posted its best month ever as AI demand keeps building — good news for the AI supply chain.

• August sales jumped 11% from July and 46% from a year earlier, the first time the company has cleared NT$80 billion in a single month.
• The driver is advanced packaging, the step that stitches AI chips together, where orders keep climbing.
• Sales for the first eight months are up 28% from last year, also a record for the period.
• Advanced packaging revenue will beat the company's earlier target of $3.5 billion this year and double next year.

Outlook: ASE expects its whole packaging and testing business to grow 35% next year as AI chip demand keeps running hot.
