2、 PPS film: an excellent substrate for high-performance engineering plastics

Polyphenylene sulfide (PPS) is a thermoplastic specialty engineering plastic with a range of excellent physical and chemical properties:

• high-temperature resistancePPS film can be used continuously for a long time at temperatures ranging from 200 ℃ to 240 ℃, and its short-term temperature resistance can even exceed 260 ℃. This characteristic enables it to exhibit excellent dimensional stability in the reflow soldering process, effectively avoiding curling deformation problems at high temperatures.
• Chemical resistancePPS has strong resistance to most acids, bases, salts, and organic solvents, and can operate reliably even in harsh chemical environments.
• Excellent electrical insulationPPS film has excellent insulation performance, which can effectively block the flow of current, avoid current leakage and short circuit of electrical equipment, and is widely used in electronic components, circuit boards, cable insulation and other fields.
• Low dielectric lossThe dielectric loss tangent (tan δ) of PPS thin film can be as low as 0.002 or below at a frequency of 10 GHz. Its low dielectric constant (ε ≈ 3.2) and low loss factor characteristics significantly reduce signal transmission loss.
• Flame retardancyPPS material itself has self extinguishing properties and can meet UL94 VTM-0 flame retardant standards without the need for flame retardants.

3、 Metalization process: a key leap from insulation to conductivity

PPS itself is an excellent insulating material, but by depositing a metal layer on its surface, it can be endowed with new functions such as conductivity, thermal conductivity, and electromagnetic shielding. However, PPS is a non-polar material with low surface energy, and the untreated PPS has weak adhesion with the metal layer - this is the main technical difficulty in the mass production of PPS metallization.

Advanced Institute of TechnologyHaving been deeply involved in the field of metallization for many years, we have independently mastered a complete set of process technologies from substrate surface pretreatment to metal layer deposition

• Physical Vapor Deposition (PVD) technologyThe company adopts advanced PVD technology, which can achieve uniform deposition of metal atoms on the surface of PPS under low temperature conditions, forming high-quality metal coatings. Compared with traditional chemical plating methods, PVD technology has advantages such as environmental friendliness, good coating uniformity, and strong adhesion.
• Roll to roll (R2R) vacuum coating production lineThe company has independently built magnetron sputtering and vacuum evaporation production lines, using roll to roll continuous production technology. This device can achieve continuous production at a line speed of 3m/min, and adjust the uniformity of the coating in real time through an online monitoring system to control the thickness deviation within ± 5%. The process features include uniform coating, strong adhesion, and support for large-scale supply.

• Applicable substrates and platable metalsThe company's applicable substrates include FEP, PI, PET, LCP, PPS, PEN, PP, etc; Plateable metals include gold, silver, copper, aluminum, tin, nickel, titanium, platinum, etc.
