Recycle Transistors, Mingjiada Recycle Bipolar Junction Transistor, Field-Effect Transistor

Shenzhen Mingjiada Electronics Co., Ltd. — Specialises in the long-term recycling of transistor ICs, including bipolar junction transistors (BJT), field-effect transistors (FET), and other products.

Recycling Process:  

1. Consultation: If you have inventory electronic components that need to be disposed of, you can send an email to chen13410018555@163.com with details of the ICs/modules you wish to sell.

2. On-site Recycling: Our company will dispatch professional staff to collect your inventory electronic components on-site and conduct preliminary testing and classification of the components.  

3. Quotation: The company will provide a corresponding recycling price based on factors such as the type, quantity, and quality of the recycled components.  

4. Settlement: Once both parties reach an agreement, specific transaction methods for delivery can be negotiated.
