Case Study: QR Code Marking for Traceability
You need to track every PCB in your production line. Many electronics factories use uv laser machines to mark QR codes on delicate surfaces. These codes help you follow each board from start to finish. When you use uv laser, you get sharp QR codes that scanners read fast. You do not see fading or smudging. The codes stay clear, even after cleaning or handling. HeatSign’s uv laser marking solutions give you high precision. You keep product integrity and meet industry rules. You also avoid damage to delicate surfaces, which is important for quality.
- uv laser marking gives you long-lasting QR codes.
- You do not worry about codes fading or getting damaged.
- You meet traceability and compliance needs with ease.
Effects on Solder Mask Integrity
You want to protect the solder mask on your PCB. If you use uv laser, you avoid heat damage. The cold process keeps the mask smooth and strong. You do not see burns or cracks. The copper stays covered. This is important for quality and safety. If you use co2 laser, you risk heat damage. The co2 laser can burn or lift the solder mask. Sometimes, the copper shows. This weakens the board and can cause problems later. You need to keep delicate surfaces safe, so uv laser is the better choice.
- uv laser does not damage delicate surfaces.
- co2 laser can cause burns and expose copper.
- You keep your solder mask strong with uv laser.
Material Compatibility: FR4, Black, and White Solder Masks
You work with many types of PCBs. Some have FR4, some have black or white solder masks. Not all lasers work the same on these materials. uv laser is compatible with sensitive materials. It marks FR4, black, and white solder masks without damage. You get clean, clear marks every time. co2 laser works fast on green FR4, but it can damage delicate surfaces. You see burns or rough edges on black and white masks. You need to choose the right laser for each job.
- uv laser works well on all solder mask colors.
- co2 laser is not always safe for delicate surfaces.
- You get better quality with uv laser on sensitive materials.
Note: Many electronics manufacturers trust HeatSign’s uv laser solutions. You get high-quality marks, protect delicate surfaces, and meet all traceability needs.
