Remtec Adds New Plating Line

NORWOOD, Mass., Dec. 21, 2010 — Remtec Inc. has completed the installation of a state-of-the-art gold-tin plating line and associated process control and quality assurance equipment.

The new line provides the company with complete integrated in-house ability to produce high-quality laser diode submounts with Zero Pullback copper metallization and selective gold-tin finish, as well as ceramic substrate packages and packaging components with gold-tin finish.

The gold-tin plating process production, statistical process controls and quality control equipment have raised the company’s quality levels. Its quality control equipment includes x-ray fluorescence, energy dispersive x-ray fluorescence and a spectrophotometer, which allows for fast, accurate control and record of critical parameters such as gold-tin composition and thickness distribution.

Its plating line includes gold-tin alloys with compositions varying from 72/28 to 80/20, with thickness specified between 3 and 50 µm. Substrates are available with multiple metallization techniques and selective plating options that permit both silver thick-film and TiW thin-film seed layers of various thicknesses, plated copper from 5 to 75 µm and NiAu finish with gold thickness from 0.1 to 2.5 µm. Ceramic and copper surface finishes also are available and can be held to <1 µm.

Remtec provides custom and semicustom ceramic packaging based on plated copper and thick film (PCTF) technology.

Glossary

fluorescence: Fluorescence is a type of luminescence, which is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Specifically, fluorescence involves the absorption of light at one wavelength and the subsequent re-emission of light at a longer wavelength. The emitted light occurs almost instantaneously and ceases when the excitation light source is removed. Key characteristics of fluorescence include: Excitation and emission wavelengths: Fluorescent materials...
spectrophotometer: A spectrophotometer is a scientific instrument used to measure the intensity of light at various wavelengths in the electromagnetic spectrum, typically in the visible and ultraviolet regions. It is commonly employed in various fields such as chemistry, physics, biology, and environmental science for a wide range of applications, including chemical analysis, color measurement, and concentration determination of substances in a solution. Spectrophotometers operate by passing a beam of light...
substrate: A substrate refers to a material or surface upon which another material or process is applied or deposited. In various fields, such as electronics, biology, chemistry, and manufacturing, the term "substrate" is used with specific contexts, but the fundamental definition remains consistent: it is the underlying material or surface that provides a foundation for subsequent processes or applications. Here are some examples of how a substrate is used in different fields: Electronics: In...
