Liquid Crystal Polymer (LCP)

Withstanding lead-free reflow soldering temperatures up to 280°C while maintaining sub-millimeter structural flatness down to 0.1mm thickness requires a specialized self-reinforcing polymer, which Celanese’s Vectra E130i delivers through its 30% glass fiber reinforced Liquid Crystal Polymer (LCP) matrix. Boasting a density of 1.62 g/cm³ and a melting point of 340°C, this high-flow grade provides an exceptional tensile modulus of 15,000 MPa alongside outstanding low-warp dimensional stability. Jucheng Precision, under ISO 9001 and IATF 16949 frameworks, specializes in micro-molding Vectra E130i for high-density 5G telecommunication and connector assemblies. Using our 5-axis CNC-machined H13 tooling, we control its anisotropic shrinkage and optimize weld-line strength, delivering defect-free parts verified by Zeiss CMM.

Fabricating three-dimensional molded interconnect devices (3D-MID) with integrated circuitry on polymer carriers requires high thermal soldering resistance and selective platability, which Celanese’s Vectra E840i LDS delivers through its 40% mineral-filled, laser-direct-structuring liquid crystal polymer (LCP) matrix. Boasting a density of 1.81 g/cm³ and a melting point of 335°C, this specialized grade contains active metal-catalysts optimized for subsequent chemical plating (copper, nickel, gold) while maintaining ultra-low warpage. Jucheng Precision, operating under strict ISO 9001 and IATF 16949 standards, specializes in high-precision molding of Vectra E840i. Backed by 35+ advanced presses and in-house 5-axis CNC tooling, we control its anisotropic shrink variables (0.1%-0.5%), delivering pristine micro-substrates verified by Zeiss CMM.

To maintain stable dielectric properties and strict coplanarity during lead-free surface mount (SMT) reflow soldering up to 300°C, Sumitomo's Sumikasuper E6008 delivers through its 40% glass fiber reinforced Liquid Crystal Polymer (LCP) matrix. Boasting a density of 1.62 g/cm³ and a heat deflection temperature of 279°C, this high-heat, high-strength grade offers an outstanding ASTM flexural modulus of 12,300 MPa and exceptional low-loss dielectric performance (0.005 dissipation factor at 1GHz). Jucheng Precision, under IATF 16949 and ISO 13485 medical frameworks, specializes in micro-molding Sumikasuper E6008. Utilizing five-axis CNC-machined S136 stainless steel tooling, we control its anisotropic shrinkage, delivering flash-free micro-bobbins verified by Zeiss CMM.

Maintaining uncompromised coplanarity and ultra-low outgassing under SMT reflow temperatures up to 255°C requires an exceptionally tough, high-precision polymer, which Toray’s Siveras LX70G35 delivers through its 35% glass fiber reinforced Liquid Crystal Polymer (LCP) matrix. Boasting a density of 1.66 g/cm³ and a heat deflection temperature of 255°C, this high-heat, high-toughness grade offers a massive ASTM flexural modulus of 16,000 MPa and excellent vibration damping properties. Jucheng Precision, under ISO 9001 and IATF 16949 certified frameworks, specializes in micro-molding Siveras LX70G35. Using 5-axis CNC-machined S136 tool cavities and 35+ advanced presses, we control its anisotropic shrinkage to deliver flash-free, thin-walled micro-components verified by Zeiss CMM.
