Titanium Mesh for PCB Plating

Titanium mesh for PCB plating is mainly used in four areas: Plating inside tiny holes (for HDI boards), Precious metal plating (like gold), Collecting electricity & filtering in tanks, New uses in solar power & hydrogen energy. This black titanium mesh is a key material for high-end electronics and semiconductor packaging. It's also the most common type of mesh DONGSHENG recycles.

Main Uses of Titanium Mesh for PCB Plating

Plating Inside Tiny Holes: This mesh works as a high-performance anode. It helps put an even layer of copper or gold inside very small holes. It handles high power well and works efficiently. This gives better coverage inside the holes and stops empty spots (voids). It's important for 5G equipment circuit boards.

Precious Metal Plating: This mesh is very stable, even in strong plating liquids (like gold cyanide). It doesn't release impurities. This keeps the liquid clean and the plating shiny. It's a key material for high-end electronics and chips.

Collecting Electricity & Filtering: People use this mesh to collect electricity or to filter solid bits out of plating liquids. This helps equipment last longer. It's common in metal processing and cleaning PCB plating liquids.

New Uses in Solar & Hydrogen Energy: It can also be used for printing silver paste on solar cells and in hydrogen fuel cell parts. This helps make new energy devices lighter and work better.

Key Features of Titanium Mesh/Plate for PCB Plating

Material: Made from high-purity titanium (TA1/TA2 or GR1/GR2).

Power Handling: Can handle up to 10,000 A/m² (≈1 A/cm²), good for fast plating.

Mesh Types:

Expanded Mesh: Diamond-shaped holes: 0.5×1.0mm ~ 1.5×3.0mm

Woven Mesh: Mesh count: 20~200. Fine mesh (like 400 mesh) is used for careful filtering.

Physical Strength:

Melting point: 1660°C (3020°F)

Tensile strength: ≥345 MPa (≈50,000 psi)
