Highly stable, anti-static, and thermal-resistant packaging solutions for automated electronic pick-and-place lines.
While Calgary, Alberta, has traditionally been recognized as a global hub for energy and resource engineering, the city is experiencing a rapid technological transition. Today, Calgary hosts a growing cluster of high-tech firms specializing in Industrial IoT (Internet of Things), aerospace electronics, subsea sensors, and smart grid control equipment. These highly sophisticated applications demand specialized electronic assemblies that can withstand extreme environmental fluctuations—ranging from freezing sub-zero winter storage to intense operating environments.
Within this regional industrial framework, the necessity of absolute reliability in electronic component packaging has never been more critical. The automated manufacturing lines (SMT/PCB assembly) operating in Calgary require carrier and cover tapes that guarantee zero static discharge (ESD), precise sealing strength consistency, and reliable mechanical feed. Any packaging failure during the pick-and-place process translates to costly production downtime, component damage, and reduced yields.
"For Calgary's contract manufacturers (EMS), matching components to high-specification carrier tapes with stable peel-back force is critical to sustaining efficiency and achieving the low-ppm defect rates demanded by modern telecom and aerospace sectors."
As a dedicated global manufacturer and factory partner, we bridge the gap between advanced micro-material science and local assembly demands. By providing specialized carrier tape accessories, custom slitting capabilities, and anti-static materials tested against extreme dry winter conditions in Alberta, we ensure Calgary facilities maintain unmatched throughput.
Registered and established in June 2007, Jiangsu Yongjia Electronic Materials Co., Ltd. has accumulated over 18 years of deep R&D and production experience in the functional tapes industry. Strategically located in the high-tech industrial belt of Nantong, our facility occupies an area of 16,000 square meters with modern production plants, advanced chemical formulation labs, and cleanroom packaging zones.
Our focus spans the entire development cycle of functional tape technologies—including formulation, coating, precision slitting, and ESD verification. We serve key markets worldwide, facilitating high-speed SMD component packaging, high-voltage transformer insulation, and advanced lithium battery insulation wrapping.

Strict control over surface resistance. Formulated with stable conductive and dissipative agents to prevent triboelectric charging during high-speed unwinding.
High optical clarity guarantees that vision systems can inspect component presence and alignment accurately before pick-up.
Maintains consistent peel strength throughout the entire reel length. Prevents the common issue of tape tearing or component jumping during carrier travel.
In today's global semiconductor supply chain, cost-efficiency and delivery reliability are critical. Operating under standard Industry 4.0 methodologies, our Chinese manufacturing plant integrates precision chemical blending, automatic multi-station high-speed coating, and digital inspection systems.
By working with Jiangsu Yongjia, Calgary electronics firms obtain direct factory prices without sacrificing quality control. We provide custom slitting to strict widths (such as 5.3mm, 9.3mm, 13.3mm, up to 21.3mm, and custom wide-format dimensions) for pocket depths of all sizes.
Calgary OEM/EMS clients benefit from direct communication with the factory's primary engineering team. We offer custom adhesive formulations tailored for specific carrier materials (Polystyrene, Polycarbonate, or APET), providing optimal solutions for challenging semiconductor assemblies.
Contact Sourcing EngineerISO certified processes ensuring consistent batches for high-yield surface mount operations.
Frequently asked technical questions regarding functional cover tapes and shipping logistics to Calgary.
Dry and cold environments typically increase static generation and can cause adhesive formulations to become brittle. To mitigate this, our heat-seal and self-adhesive cover tapes are formulated with specialty anti-static elements and temperature-resilient adhesive polymers. We conduct thermal cycle testing from -30°C to 70°C to ensure the peeling force remains within the standard limits of EIA-481 guidelines even in low relative humidity.
Heat-Seal Cover Tape (HSA) requires heat and pressure to activate the adhesive backing, providing robust, long-term bond strength and high aging stability. It is the industry standard for high-speed, cost-sensitive passive components. Self-Adhesive Cover Tape (PSA) features pressure-sensitive adhesive that bonds at room temperature without requiring heat. It is typically selected for heat-sensitive components (such as chemical sensors or high-value ICs) and applications requiring simple tape application processes.
We coat our ESD cover tapes on both the top and bottom surfaces using a proprietary conductive coating matrix. The surface resistivity is kept between 105 and 1011 ohms, which prevents electrostatic charges from transferring to sensitive semiconductors. We perform inline resistivity testing during the coating and slitting phases.
Our slitting technology allows us to maintain a width tolerance of ±0.1mm. This high precision is crucial for narrow cover tapes (e.g., 5.3mm tapes designed for 8mm carrier tapes packaging 0402 or 0201 passive components), ensuring smooth feeding on automated feeders without jamming.
Yes. All materials manufactured by Jiangsu Yongjia are tested by third-party testing institutions (such as SGS). They comply with RoHS 3 (EU) 2015/863 regulations and do not contain substances of very high concern (SVHC) listed under the EU REACH framework. We provide updated certificates with every shipment.
For optimal performance, tapes should be stored in their original packaging in an environment kept at 20°C - 25°C and 40% - 60% relative humidity. Under these conditions, our heat-seal cover tapes have a shelf life of up to 2 years, while self-adhesive cover tapes are recommended to be used within 1 year from the manufacturing date.
