Taiwan's chip-testing interface maker Yingwei (Wintest, 6515) posted its third straight record month of sales in August, a strong sign that the AI chip boom is still accelerating.

• August sales more than tripled from a year earlier, and sales for the first eight months of 2026 nearly doubled.
• The company says the problem is not demand but supply — it cannot make enough test hardware fast enough.
• Capacity will be expanded by another 50% between the second and third quarters of next year.
• AI chips now need far more connection pins than old CPUs did, and each jump in pin count pushes selling prices higher.
• Its current test platform can handle chips up to about 20,000 pins, covering the top-end AI chips expected over the next two years.

Outlook: As long as AI chip orders keep coming, sales should keep climbing, with the added capacity arriving late next year.
