HDI PCB Board for Inverter with Green Solder Mask
♦ What is Solder Mask?
Solder Mask (also called solder resist or solder stop mask) is a thin, protective layer of polymer applied to the copper traces of a printed circuit board (PCB) to prevent oxidation, short circuits, and unintended solder connections during assembly.
♦ Types of Solder Mask?
| Type | Description | Common Uses |
|---|---|---|
| Liquid Photoimageable (LPI) | Applied as a liquid, exposed to UV light, and developed (most common). | Standard PCBs, high-precision designs. |
| Dry Film Solder Mask | Pre-formed film laminated onto the PCB, then UV-exposed and etched. | High-density PCBs (HDI). |
| Top & Bottom Side Masks | Applied only to specific sides (e.g., single-sided PCBs). | Simple boards with limited layers. |
| Peelable Solder Mask | Temporary mask that can be removed after soldering. | Selective protection during assembly. |
♦ Types of Solder Mask?
| Feature | Solder Mask Covered | Exposed Copper (No Mask) | Solder Mask Defined (SMD) Pads | Non-Solder Mask Defined (NSMD) Pads |
|---|---|---|---|---|
| Protection | Yes | No | Partial (mask covers edges) | No (pad extends beyond mask) |
| Solderability | Prevents solder spreading | Solder adheres fully | Controlled solder flow | More solder volume |
| Common Use | General traces | Test points, ground pads | Fine-pitch components (BGAs, QFNs) | High-reliability soldering |
