🔍 What holds the layers of a multilayer PCB together?
PCB prepreg is a key material used during the lamination process. It helps bond PCB layers, provide electrical insulation, and maintain controlled thickness throughout the board structure.
Choosing and processing the right prepreg is important for achieving consistent lamination, reliable layer bonding, and quality multilayer PCB construction.
📖 Want to understand how prepreg works? Our latest blog explores its types, benefits, and role in the PCB lamination process.

🔍 What keeps a PCB protected during soldering and everyday use?
The solder mask is a thin protective layer applied to a PCB that helps shield copper traces, reduce the risk of solder bridging, and keep the right pads exposed for component assembly.
Beyond protection, solder mask plays an important role in supporting PCB durability, assembly quality, and long-term performance.
But what types of solder mask are available, and how is it applied during PCB manufacturing?
📖 Our latest blog explores the types, application process, key benefits, and role of solder mask in PCB manufacturing.
👉 Read the full blog to learn why solder mask is an essential part of a reliable PCB.
