Local Procurement of ESD Solutions for OA Equipment in Vietnam | Selecting Static Elimination Brushes and Conductive Fibers Aligned with OEM Design Philosophy

To suppress defects caused by static electricity in the assembly process of OA equipment, selecting static elimination materials tailored to the design philosophy of each individual model is indispensable. Through collaboration between our Vietnam base and cooperative manufacturers, we evaluate and supply model-specific static elimination brushes, conductive fibers, and conductive adhesive tapes locally. This enables customers to break away from import dependency and realize a stable supply. The "Procurement Challenges of Static Elimination Components" Manifesting in the Overseas Localization of OA Equipment We want to localize the procurement of static elimination components for OA equipment in Vietnam. However, because the design philosophy differs for each model, off-the-shelf general-purpose products do not fit.It was necessary to select static elimination components tailored to the specific design philosophy of each manufacturer.● When the issue manifests: Overseas expansion and local procurement phases.● Main impacts: Risk of stockouts due to imports, inability to secure design-compliant products locally, and countermeasures against defects in the assembly process. Why Off-the-Shelf General-Purpose Products Do Not Fit: Differences in Design Philosophy for Each Model Prolonged lead times caused by procurement and supply chain factors. Specifications for static elimination components are highly fragmented by specific models.●Basis for Identification: Customer hearings and prototype evaluations. Countermeasures Attempted So Far and Their Limitations Diverting local general-purpose brushes (insufficient static elimination performance), continuing to order Japanese products (lead times exceeded).Based on these limitations, we adopted the following approach as a more radical and fundamental solution. Solution Approach: Design Philosophy Interviews × Local Prototype Evaluation × Model-Specific SKU Management In coordination with our overseas bases and cooperative manufacturers, we select static elimination brushes and conductive fibers tailored to design specifications, and conduct on-site sample evaluations. STEP. 01 Custom Specification Capability Organizing static elimination requirements for each model to select the optimal fiber type, density, and tuft length. STEP. 02 Prototyping & Evaluation Conducting on-site evaluations tailored to the assembly line. STEP. 03 Local Inventory Management Storing required quantities to ensure short lead-time supply.

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.
