[Circuit Board Manufacturing Example] Small Submount Board for High-Density Mounting

This is an introduction to a case where side patterning technology for substrates has been established.

We will introduce examples of manufacturing substrates for implementing semiconductor devices such as optical modules for optical devices (DVD/CD recorders, optical communication), semiconductor laser diodes, and semiconductor photodiodes. With the trend towards miniaturization and thinness of devices, the demand for implementing multiple elements in a low area and high density is increasing. Therefore, we have established side patterning technology for substrates. It is possible to form circuits on one to four sides of high heat dissipation ceramic substrates such as alumina and aluminum nitride. 【Case Overview】 ■ Base Material: Alumina, Aluminum Nitride, etc. ■ Conductor Film Composition (Au-based wiring, Cu-based wiring *Pt barrier film compatible) ■ Resistance Film Composition (TaN, NiCr), Solder Flow Prevention Film (Cr, Solder Resist) ■ Implementation Support: Wire/Ribbon Bond, Bump, Various Soldering Specifications Available ■ Testing/Reliability: Compatible with MIL specifications and other customer-specified specifications *For more details, please refer to the PDF document or feel free to contact us.
