High reliability, controlled peel force, and superior electrostatic protection optimized for automatic high-speed surface mount placement.
Undergoing an unprecedented transformation, driven by automation, material science breakthroughs, and sustainability parameters.
As micro-electronic packages become smaller (such as WLCSP and 01005 passives), precision in component transport carrier materials is paramount. High-speed SMT picking requires structural integrity and tight dimensional tolerance on cover tapes to avoid component jamming, loss, or incorrect orientation.
Electrostatic discharge can destroy vulnerable microchips. Our custom-engineered carrier and cover tapes integrate advanced anti-static coatings (both dissipative and conductive properties) that prevent charge generation during high-speed peel-off, protecting sensitive wafer dies.
During the SMT thermo-bonding processes, standard tapes fail due to outgassing and thermal degradation. Jiangsu Yongjia's heat-seal carrier tapes exhibit exceptional stability under temperatures exceeding 200°C, providing continuous seal consistency without residue transfer.
Registered and established in June 2007, Jiangsu Yongjia has developed into an industry-leading comprehensive service provider of functional tape products. Nestled in the high-tech industrial corridor of Nantong, China, our operations span a state-of-the-art facility covering 16,000 square meters.
We focus on the core track of functional tapes for the electronics and semiconductor industry. Our capabilities range from custom synthetic formulation, coating, precision slitting, to direct support for automated packaging operations. With scientifically planned production lines, class 1,000 cleanroom environments, and a dedicated R&D laboratory, we guarantee consistent quality and high yield for global electronic assembly lines.
Discover how our diverse product segments align with the complex assembly requirements of modern high-density PCBs and integrated circuit carriers.
Our Standard & Enhanced High Temperature Series Heat Seal Cover Tapes rely on high-precision thermal bonding. By adjusting sealing pressure, temperature, and dwell time, these tapes offer extremely stable peel force profiles. For ambient-sensitive components, our Self-Adhesive Cover Tapes utilize advanced pressure-sensitive adhesives (PSA), providing strong bond strength and easy release without requiring thermal excitation.
Engineered for high dielectric strength, our Acetate Cloth Tapes (available with or without release liners, featuring flame-retardant chemistry) deliver outstanding puncture resistance and conformability. When combined with our ultra-strong Glass Fiber Tapes, they form a robust mechanical barrier capable of securing high-voltage battery packs, transformer windings, and heavy-duty industrial electric circuitry.
Our PET Electrical Protection Tapes use a tough polyester film backing coated with specialized acrylic or silicone adhesives. They offer excellent resistance against solvents, acids, and high temperatures, ensuring no adhesive residue is left on copper terminals, PCBs, or lithium battery casings during manufacturing and chemical washing steps.
Addressing technical challenges in local automation factories, stamping plants, and assembly cleanrooms across the globe.
Securing sensors, ECUs, and high-frequency radar modules. Materials must survive under-hood temperature extremes and resist vibration-induced peeling.
Used as terminal carrier tapes during precision metal punching. High tensile strength prevents snapping under immense mechanical tension.
Enabling packaging of discrete components, MEMS, and advanced logic circuits. Guaranteed anti-static properties protect delicate gates.
Flame-retardant acetate tapes isolate power control modules, transformer coils, and white goods internal wiring harnesses safely.
Operating from Nantong, Jiangsu Yongjia leverages the world's most integrated chemical and electronic materials supply chain cluster. This geographic and industrial integration allows us to source premium base materials with zero lead-time volatility, insulation from commodity shocks, and rapid prototyping capabilities.
By utilizing high-speed precision coating lines and automated defect inspection technologies, we achieve a continuous production yield of 99.7%. This efficiency allows us to optimize manufacturing costs and pass those savings directly to our global wholesale partners. Our strategic proximity to the Port of Shanghai ensures rapid, cost-effective container dispatch to Europe, North America, and Southeast Asia.
As global electronics manufacturing shifts towards narrower tape widths (such as 4mm and 8mm pocketed carriers) and higher pick-and-place velocities, Jiangsu Yongjia's engineering department is focused on next-generation materials:
Every meter of tape engineered by Jiangsu Yongjia conforms to international electronic specifications, ensuring trouble-free integration into automated assembly systems.
We perform rigorous gas chromatography-mass spectrometry (GC-MS) testing to guarantee that our acetate cloth, PET, and cover tapes are fully halogen-free, non-toxic, and meet RoHS, REACH, and California Proposition 65 standards.
Our carrier cover tapes are manufactured to strict width tolerances of ±0.1mm, ensuring flawless alignment with pocket configurations and standard feeder widths. We test for consistent peel force range (between 10g and 130g as defined by EIA standards).
From initial design trials to SMT process adjustments, our global applications team offers complete technical support. We assist your engineering department with thermal sealer calibration, peel strength optimization, and substrate compatibility verification.
