Selecting the appropriate glass substrate is critical to the performance of the final product. Engineers select glass materials with appropriate thermal properties, mechanical properties and chemical stability based on design requirements and application scenarios.

Graphical conversion

During the graphical conversion stage, the substrate design is converted into a machine-readable data format, usually a Gerber file. These files contain information such as substrate wiring, hole locations, and component locations, providing necessary guidance for subsequent manufacturing steps.

Printing

Printing is one of the key steps in manufacturing glass material packaging substrates. At this stage, the substrate’s graphic layout is printed on the surface of the glass substrate, forming a template for circuit traces and component locations.

Chemical corrosion

Chemical etching is the process of converting patterns printed on the surface of a substrate into conductive lines. At this stage, the substrate undergoes a series of chemical treatments to metallize the parts not covered by printing to create conductive pathways.

Tin covering

The tin covering is to protect the conductive traces and provide a soldering surface. At this stage, the substrate surface is coated with a layer of tin to protect the wires from corrosion and provide good soldering performance.

Assemble

In the assembly stage, electronic components are mounted on the substrate and soldered. This involves attaching the components to the substrate via surface mount technology (SMT) or plug-in assembly and ensuring they are connected to the wires.

Test

Finally, the last critical step in the manufacturing process is testing. At this stage, manufacturers conduct various functional tests and performance evaluations on the assembled substrate to ensure that it meets design requirements and quality standards.
