Overseas Procurement + Domestic Slitting of PET Film for Power Cables | Cost Reduction While Maintaining Equivalent Quality

In response to the risks of rising domestic PET film prices and supply chain factors, we offer a combined package of new overseas PET film sourcing and domestic slitting services for power cable manufacturers seeking both cost improvement and stable supply. With our three-pronged advantage of “Equivalent Quality × Cost Reduction × Domestic Support,” we contribute to maintaining the competitiveness of your cable selling prices.

Deteriorating Cost-to-Sales Ratio of Power Cables and Demands for “Equivalent Quality × Cost Reduction”

The goal is to reduce the procurement cost of PET film for power cables, while maintaining quality equivalent to conventional products.
Domestic products offer stability but come at a high price. Overseas products feature attractive pricing but raise concerns regarding quality and logistics.
●Scenarios where this becomes apparent: Continuous cost structure review phases. Initiated by proposals from Fuji Chemi.
●Main impacts: Deterioration of the cost-to-sales ratio, decline in cable selling price competitiveness.

Why Domestic Price Renegotiations Have Reached Their Limit: Price Increases and Supply Chain Factors

Rising prices of domestic PET film and supply chain factors (extended lead times).
●Specific Rationale: Prototype evaluation of overseas PET candidates, demand volume estimations.

Measures Tried So Far and Their Limitations

Price renegotiations for domestic products (limited impact), consideration of direct import of overseas PET (burden of customs clearance and slitting processes).
Based on these limitations, we adopted the following approach as a more fundamental solution.

Solution Approach: New Overseas Supplier Sourcing × Domestic Stock × Slitting Process

By sourcing from new overseas manufacturers and combining it with domestic inventory + slitting processing, we maintain the same delivery conditions for customers as conventional products.

STEP. 01

Overseas Supplier Sourcing

Discovering overseas PET that matches required physical properties

STEP. 02

Domestic Stock

Holding buffer stock at the Mito Processing Center

STEP. 03

Focused Development of High-Frequency Compatible FPC (Low-Dielectric Materials such as LCP) | On-Site Hearing-Based Proposals Utilizing Overseas Bases

The high-frequency FPC field is seeing growing requirements for physical properties due to the widespread adoption of 5G and next-generation communication devices. We provide a "demand-driven" solution that aggregates information on manufacturers' new and developmental products, and matches them with needs through on-site hearings at local factories via our overseas bases. Mismatches Between Required Properties and Supply Frequently Occurring in the High-Frequency FPC Market While market requirements in the electronic components and equipment industry are updated daily and demands for high-frequency compatible FPCs (such as LCP) are rising, projects tend to stall due to a mismatch between required physical properties and actual supply.Through meetings with customers' procurement departments, it became clear that it is essential to gather raw feedback from local bases.● Scenarios where this becomes apparent: New product development and existing product improvement phases. Targeted at mobile and consumer devices.● Main impacts: Supply anxiety, prolonged lead times, procurement delays after design freeze, and falling behind competitors. Why Mismatches Occur: Supply Stability, Prolonged Lead Times, and Advanced Property Requirements Supply stability issues and prolonged lead times with overseas suppliers. Required physical properties are highly advanced, making it difficult to match them with manufacturers' developmental products.● Grounds for identification: Meetings with customers' procurement departments and local hearings at overseas bases. Countermeasures Attempted So Far and Their Limits Performance insufficiency with general-purpose FPC materials and unfulfilled requirements when relying on a single manufacturer introduction.Based on these limitations, we adopted the following approach as a more fundamental solution. Solution Approach: Introduction of Manufacturers' New Products × Local Hearings × Demand Matching A matching-driven sales approach that introduces manufacturers' new and developmental products to existing customers while uncovering demand at overseas bases through the Fuji Chemi network.

Achieving Space-Saving in Electronic Equipment with Anisotropic Conductive Film (ACF) × Local Slitting Process in Thailand | Integrating Connection, Insulation, and Adhesion into a Single Sheet

In OA equipment and EMS fields, demands for thinner products and cost reduction are intensifying simultaneously, while the conventional mounting method, where connection, insulation, and adhesion are handled by separate components, has reached its limits. By combining material integration into high-performance Anisotropic Conductive Film (ACF) with local slitting and small-lot supply at our Thailand base, we provide solutions that simultaneously achieve space-saving inside devices, yield improvement, and cost reduction. It has already been adopted by multiple OA equipment manufacturers and EMS providers. Simultaneous Demands for "Space-Saving" and "Cost Reduction" Occurring in OA Equipment and EMS Fields In the fields of OA equipment and EMS (Electronics Manufacturing Services), market demands for even thinner and smaller products are growing year by year. At the same time, price competition for final products is becoming fiercer, making the balance between maintaining functionality and reducing costs the biggest challenge for design and procurement departments.Particularly for the connection parts of electronic components, conventional wisdom dictated that three functions—conduction, insulation, and adhesion—be handled by separate components. However, this has become a structural bottleneck that causes more complex assembly processes, increased thickness, and higher costs. On the manufacturing lines of local factories in Thailand, deterioration in yield and inefficiencies in assembly processes caused by these connection components have already become apparent."We want to make the product one step thinner. However, we cannot compromise on connection strength, insulation performance, or adhesion reliability. Furthermore, we also want to reduce costs."——We receive many such inquiries from the design and procurement departments of local factories in the ASEAN region. Why Space-Saving is Impossible: Limits of the Mounting Method Layering Single-Function Connection, Insulation, and Adhesion Components The root causes identified from on-site witness inspections and cross-checking mounting data with yield data can be summarized into the following two points:・Insufficient mounting space at connection points: The overlapping of multiple components results in a loss of design flexibility.・Inefficiency of separate components handling conduction, insulation, and adhesion: Alignment and pasting processes for each component increase, leading to higher assembly time and defect rates.These issues cannot be resolved by improving individual parts; integration at the material design level is required.The grounds for identifying the causes are the comparison of the following three points:・On-site observation at customer manufacturing facilities・Cross-checking of mounting data and yield data・Deconstruction of the cost structure of existing component configurations Countermeasures Attempted So Far and Their Limits The countermeasures previously attempted by many customers face a common barrier:・Replacement with thinner conductive tape: Insufficient connection strength made it unacceptable.・Consideration of adopting local general-purpose ACF: Failed to meet required physical properties for heat and chemical resistance.・Reduction of assembly man-hours through process simplification: Did not achieve fundamental thinning or cost reduction.Given these limits, "material integration into high-performance ACF that realizes the three functions of conduction, insulation, and adhesion in a single sheet" and "acceleration of evaluation and mass production response through local processing and small-lot supply" emerge as the most effective measures. Solution Approach: Material Integration into High-Performance ACF × Local Slitting in Thailand × Small-Lot Supply Centering on material integration into high-performance Anisotropic Conductive Film (ACF), we accompany you from the design stage to mass production through the combination of the following three steps. STEP. 01 Exploring High-Performance ACF Grades and Sample Prototyping From the high-performance ACF lineup of Japanese manufacturers, we select the optimal grade that meets required physical properties such as heat resistance, chemical resistance, connection strength, and adhesion reliability through matrix comparison. Following sample prototyping, we proceed with functional verification under the customer's mounting conditions to minimize risks before mass production. STEP. 02 Local Slitting Process and Direct Line Input at the Thailand Base Leveraging the network of our Thailand base, we perform slitting processes to the width and size specified by the customer. By supplying it in a shape that can be directly input into the production line, you can transition smoothly from evaluation to mass production without gaps. We also support quotation and settlement in local currency. STEP. 03 Division of Roles Inside and Outside Japan and Shortened Lead Times The Japan side handles ACF evaluation, formulation proposals, and heat resistance data preparation, while the Thailand side takes charge of mass production slitting and local inventory. Through this division of roles between both bases, we maximize the prototyping speed in the evaluation phase while simultaneously establishing a short-delivery supply to local factories. Fuji Chemi Trading's Supply System: Triangular Collaboration among Japan Headquarters, Thailand Base, and Mito Processing Center This solution is established through the division of roles among three bases:・Headquarters / Technology: ACF evaluation / formulation proposals / heat and chemical resistance data preparation / customer contact window・Thailand Base (Local Subsidiary): Local slitting process / local inventory storage / local currency quotation and settlement・Mito Processing Center: Parallel operation of slitting and die-cutting on the Japan side / immediate shipment of evaluation samples● Supply System: Slitting into small rolls at customer-specified widths, overseas inventory support, and immediate shipment of small-quantity samples for evaluation are possible. We have established a system to seamlessly accompany you from the evaluation phase to mass production. Results of Implementation: Simultaneous Achievement of Component Count Reduction, Thinning, and Yield Stabilization We have received the following qualitative and quantitative result reports from companies that have implemented this solution:・Reduction in the number of components by realizing connection, insulation, and adhesion with a single sheet・Thinning of products by reducing overlapping layers・Stabilization of yield (reduction of mounting defects)・Cost reduction due to material integration effects・Reduction of SKUs subject to inventory management● Implementation Lead Time: By sharing customer prototyping and evaluation inside and outside Japan, the time to mass production is shortened. Anticipated Ripple Effects and Horizontal Expansion: Three Returns Opened Up by ACF × Local Processing Material integration into ACF can be horizontally expanded to areas other than this case. Please use this as material for internal proposals.1. Expansion to other FPC/glass substrate connection projectsIt can be applied to all projects involving FPC connections, such as camera modules, sensors, and automotive displays. All fields requiring thinning and highly reliable connections, such as smart devices, wearable equipment, and automotive cockpits, are targeted.2. Simplification of the assembly process → Improvement of manufacturing line throughputIf assembly processes are reduced through material integration, the throughput of the manufacturing line itself will improve. This will be highly evaluated by manufacturing departments as a measure to increase production without expanding line capacity.3. Standardization of components within ASEAN and gaining inquiriesBy expanding the ACF adopted in Thailand to Vietnam factories and China factories with the same specifications, the "standardization of components" desired by the global headquarters' procurement department can be achieved. In addition, by turning it into a "small-lot evaluation kit" utilizing ACF evaluation know-how, it can lead to gaining inquiries from new customers. Differences from Competitors: Why Fuji Chemi Trading is Chosen While many trading companies handle only raw film materials, our unique strength lies in our ability to handle everything up to "ACF evaluation + local slitting + small-lot immediate delivery" within a single company. Trading companies with networks capable of maintaining Japanese quality in local Thailand are limited, and we can proceed from the evaluation phase to the mass production phase without disrupting the responsible contact window.・Difference from raw material sales-type trading companiesOne-stop support from evaluation, processing, to small-lot immediate delivery・Difference from local trading companiesProviding Japanese quality standards, Japanese language support, and materials for management・Difference from processing subcontractorsHandling everything from material selection, grade proposals, to heat resistance data preparation Product Information: Spec Overview of Anisotropic Conductive Film (ACF) The Anisotropic Conductive Films with a proven track record of adoption can be selected from multiple grades depending on the application and mounting conditions.
