- Preventing Damage to Circuit Lines
Plugging Services Offered by WellCircuits Limited
WellCircuits Limited provides two specialized plugging services tailored to customer needs:
- Resin Plugging: Utilizes solvent-free ink to address difficult filling issues and reduce the risk of ink cracking during heating.
- Electroplating Filling: Controls copper deposition rate using additives, beneficial for continuous multi-layer laminated hole boards or high-current PCB designs.
Key Considerations During PCB Assembly
- Avoiding Flux Residue Blockage in VIAs
- Preventing Solder Beads Popping Out During Wave Soldering
- Avoiding Solder Bridges Caused by Surface Tin Flow
- Ensuring PCB Board Qualification Through Testing
Understanding PCB Solder Mask Openings
The PCB solder mask layer, coated with protective ink, plays a crucial role in PCB fabrication. Solder mask openings expose copper pads for soldering, facilitating signal measurement and preventing leakage.
Types of Solder Mask Inks
- Liquid Photosensitive Ink: Ideal for small batch, high-precision PCB production with personalized designs.
- UV Solder Mask Ink: Features rapid fixation, heat resistance, and strong adhesion for single-sided and double-sided circuit boards.
