🔍 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.

🔍 Solder Resist vs. Solder Mask - Are They Actually Different?
When it comes to PCB manufacturing, solder resist and solder mask are often used interchangeably. Both refer to the protective coating applied over a circuit board to protect copper traces, reduce the risk of solder bridges, and leave specific pads exposed for component soldering.
But understanding their terminology, purpose, and role in the PCB manufacturing process can help you better understand PCB quality and assembly requirements.
📖 Our latest blog explains the difference between solder resist and solder mask, how they function, and why this protective layer matters in PCB manufacturing.

✨ What makes a solder joint reliable?
Flux plays an important role in the soldering process by helping remove oxidation from metal surfaces and improving solder wetting. The result is a cleaner connection that supports consistent and reliable solder joints during PCB assembly.
But how exactly does flux work, and why is it essential for achieving quality solder connections?
Our latest blog breaks down what flux is, how it works, and why it matters in PCB assembly.
👉 Read the full blog and discover how the right soldering process can support better PCB assembly results.
