Abstract: A series of laser direct structuring (LDS) materials including LDS-PA6, LDS-PPS,
LDS-PA6/PPS, and long glass fiber (LGF) reinforced LDS material (LDS-PA6/PPS/LGF) were prepared
based on polyamide 6 (PA6), polyphenylene sulfide (PPS) and their composites. The properties of the
materials were characterized by TGA, thermal deformation tester, pendulum impact tester and material
testing machine. The morphologies of regions after laser activation and layers after selective plating, and
the reliability of plating layer were evaluated by optical microscope, SEM, crosscut tape and salt spray test.
The results revealed that the thermal properties, water absorption resistance, flexural strength and modulus
of LDS-PA6/PPS were between those of LDS-PPS and LDS-PA6. The introduction of LGF made the initial
thermal decomposition temperature of LDS-PA6/PPS increased by 20 ℃. While the heat deflection
temperature and flexural modulus of LDS-PA6/PPS/LGF were improved by 62% and 102% compared with
those of LDS-PA6/PPS, respectively. It was found that increasing the laser energy and frequency,
decreasing the scanning speed and hatch distance could enhance the superposition of laser pulse and
effectively coarsen the surface of materials, which eventually contributed to the adhesion and deposition of
copper particles during the subsequent selective plating process. The optimum laser activation process
conditions were as follows: laser energy of 10 W, frequency of 70 kHz, scanning speed of 2500 mm/s and
hatch distance of 25 µm. The copper coating of the LDS materials had uniform copper particles (particle
size of approximately 40 µm), smooth surface and excellent electrical conductivity, the adhesion between
