Background:

OptoTech is a company of VSCEL laser technologies, specializing in high-performance VSCEL lasers. They cater to various industries such as telecommunications, medical devices, and scientific research. OptoTech Solutions is facing challenges with the thermal management and electrical performance of their VSCEL lasers, which are crucial for maintaining laser stability and efficiency. They are seeking a reliable ceramic PCB supplier that can provide high-quality ceramic circuits for their VSCEL laser systems.

PCB challenge:

The ceramic PCB needs a very good flatness to perform good thermal management for their VECEL lasers.
The whole board is covered by copper, it is not easy to protect from oxidation and scratch.
Some specific areas required 200um copper, so it needs to proceed plating process several times to achieve the required thickness, which will affect the surface flatness.
The customer wants to add solder paste on the pads for 1mm, it is difficult to control the thickness, especially since the copper thickness is different on some pads.

Solution:

During the second plating, we protected the copper surface so that no need to add extra copper by film, all the operators paid high attention during the whole process, and finally we finished the products and applied the solder paste successfully by a stepped stencil.

Result and Benefits:

The customer appreciated our hard work and dedicated work attitude, they gave us a big thump up and sent some other similar projects to us. Now we are still in cooperating new project.
