The Top-marking Rule for SOT23-5/6 Packaged Products


Question: What's your top marking rule?

Answer: The creative patent-pending Top-marking Rule for our SOT23-5/6 Packaged Products is:

(1) 4-5 Alphanumeric Letters, mostly 5;

(2) First 2 Letters stands for the Product;

(3) Rest 2-3 Letters comprises of Production Tracking Information.

The innovative and most amazing thing is that each product has its unique 2-letter code and each batch of production has a unique 5-letter marking code, even though we use 4-digit coding system.

Following table shows the marking rule for some products.
