Key Components and Their Functions in PCB Production
Every functional electronic system relies on four critical elements working in harmony. These parts form a complete unit that ensures signals flow smoothly while surviving daily wear and tear.
Substrate, Copper, Solder Mask & Silkscreen
The foundation begins with fiberglass material called substrate. This layer gives the board structural stability and heat resistance. It supports all other components like a skeleton holding organs in place.
Thin copper sheets form conductive pathways when etched. These traces act as highways for electrical signals between parts. Without proper copper patterning, devices couldn't process data or transmit power.
A green solder mask coats the surface after etching. This polymer shield prevents oxidation and accidental short circuits. It also resists environmental factors like humidity that degrade exposed copper over time.
White markings called silkscreen complete the assembly. These labels help technicians identify components during repairs or upgrades. Clear symbols reduce assembly errors by 43% compared to unmarked boards.
| Component | Primary Material | Function | Performance Impact |
|---|---|---|---|
