Introducing Butterfly Package: A Comprehensive Guide for Dealers

As a dealer in the electronics industry, it’s important to stay up-to-date on the latest packaging solutions available. One such solution that has gained popularity in recent years is the butterfly package. In this article, we’ll provide a comprehensive guide to butterfly packages, including their benefits, applications, and how they compare to other packaging options.

What is a Butterfly Package?

A butterfly package is a type of opto-electronic package that is used for the packaging and protection of laser diodes. It is named after its shape, which resembles a butterfly with two wings. The package consists of a base, a lid, and two leads for electrical connection. The base and lid are typically made of metal, such as Kovar or copper, and the leads are made of gold or aluminum. The package is hermetically sealed to protect the laser diode from environmental factors such as moisture and dust.

Benefits of Butterfly Packages

Butterfly packages offer several benefits over other packaging options. Firstly, the butterfly shape of the package allows for efficient heat dissipation, which is important for the longevity and reliability of the laser diode. Additionally, the hermetic sealing of the package provides excellent protection against environmental factors that can damage the laser diode. The use of gold or aluminum leads also ensures high electrical conductivity, which is important for the proper functioning of the laser diode.


In conclusion, butterfly packages are an excellent packaging option for laser diodes due to their efficient heat dissipation, hermetic sealing, and high electrical conductivity. They are commonly used in telecommunications, medical, and scientific applications where reliability is of utmost importance. As a dealer, it’s important to be aware of the benefits and applications of butterfly packages in order to provide the best solutions to your customers.
