These photodetector ceramic packages are intended for light-receiving devices such as photodiodes, avalanche photodiodes (APDs),infrared detectors,optical sensors,and other optical receiving components. Unlike general-purpose IC packages,photodetector packaging must account for optical access,detector position,cavity geometry,light shielding,and PCB interface requirements in addition to chip mounting and electrical connection.
Alumina ceramic offers electrical insulation,mechanical rigidity,dimensional stability,and compatibility with metallization processes,making it well suited to compact optoelectronic assemblies that require precise positioning and reliable integration.

Frequently Asked Questions
Why Use Alumina Ceramic Packages for Photodetectors? How Do They Suppress Stray Light and Noise?
Plastic SMD housings frequently suffer from moisture-induced dark current drift, mechanical warping, and internal optical crosstalk. INNOVACERA’s alumina SMD ceramic packages provide rigid dimensional stability and high dielectric insulation. Our custom cavity structures and light-shielding walls effectively suppress stray-light interference around the active sensing area, while precision internal metallization minimizes parasitic capacitance for photodiode, APD, and LiDAR optical receiver modules.
Need Tailored Cavities or Optical Apertures for Optical Sensors? How to Order Custom Photodetector Packages from INNOVACERA?
