What's the difference between LDS and LRP and LAP?

All three are tontop 3D-MID technology based on three-dimensional laser. LDS is a laser-induced modified material, followed by selective metal plating. The LRP is coated with silver paste and then laser trimmed. LAP is a common material that is induced by laser and then selectively plated with metal.

1. From the perspective of antenna tuning, LAP is the best tuning, LDS will affect the dielectric constant because of the material, and LRP is the most difficult tuning. The resistance of silver paste is not as good as that of electroless copper plating and electroless nickel plating, but LRP is relatively environmentally friendly.

2. From the perspective of three-dimensional realization ability, LAP = LDS & gtLRP, which is easy to understand. LRP is printed, and simple patterns are easier to get, while the first two are mainly based on laser. Wherever the laser can see, it can be laser carved, that is, it can be metallized.

3. From the cost advantage, LAP & gtLDS, because LAP does not need special modified materials, and special materials are expensive. Simple picture, LRP>；; Circle, but in fact, the mobile phone antenna is more complicated now, so in summary, LRP may not have an advantage, look at the drawings.

4. From the perspective of process maturity, both LDS and LAP have been mass-produced, but LRP has not been mass-produced.
