1.Product Description

1. What is SMT assembly used for?

SMT assembly was developed to create an improved and more powerful electronic product. You can find various SMT applications in any office or home.

SMT has primarily taken over electronics manufacturing. If a product needs to be smaller, faster, lighter, or more powerful, it will likely be produced via SMT assembly instead of the through-hole process.

2. What are the SMT assembly capabilities of NEMO Manufacturing?

In the contract manufacturing industry, which is highly competitive, NEMO Manufacturing has taken on the mission of exceeding every customer’s expectations. We are committed to consistently producing reliable products, providing superior customer service, and maintaining a talented and experienced staff. NEMO customers can expect excellence from us because we demand it from ourselves.
