From old customers to new markets: East Chemical's NMP solution is recognized by Korean semiconductor companies again

"In the semiconductor packaging process, the complete removal of adhesives is directly related to the chip yield. A well-known Korean semiconductor material company recently selected East Chemical's high-purity NMP N-methylpyrrolidone as the core process solvent through the recommendation of an old customer. This is the third international company to reach cooperation through "customer referrals" this year."

✅ Project background: High-end precision applications place higher demands on  NMP quality

The Korean customer is mainly engaged in the research and development and production of semiconductor packaging materials. In its production process, N-methylpyrrolidone NMP is a key solvent for cleaning and removing adhesives, and has extremely high requirements for purity, stability and impurity control.

After inspecting multiple suppliers, the customer finally chose the East Chemical N-methylpyrrolidone NMP product recommended by a long-term old customer.

🤝 Customer evaluation: Professional service + high-quality NMP products, reliable cooperation

The new customer said that when choosing an NMP supplier, they attach great importance to the following points:

Whether the product can stably meet the quality standards of the semiconductor process level

Whether the supply is stable and timely

Whether the service response is fast and professional

In the past services to old customers, East Chemical has always adhered to the concept of **"customer first, professional and efficient", ensuring the quality traceability and factory inspection pass rate of each batch of NMP products 100%**, and assisting customers to ensure delivery through efficient logistics.

The word-of-mouth recommendation of old customers and the strong strength of our company allowed new customers to quickly reach cooperation intentions and complete the first batch of purchases in a short period of time.
