LEARY（莱尔科技） / 禾惠电子: FFCs and Functional Adhesive Films
Slim connections for displays, automotive electronics and battery signal collection.
What Is an FFC? Structure and Connection
A flexible flat cable (FFC) is a ribbon-like electrical cable with multiple flat metal conductors covered by thin insulating films. It connects circuit boards to one another or to modules such as displays, carrying signals or electrical power.

Board B / moduleFFC: thin ribbon-like cable
Align the exposed termination contacts with the connector contacts, then connect using the specified insertion depth and procedure. Where a locking mechanism is provided, operate it according to the connector instructions.
Schematic only; thickness, width and conductor count are not to scale. Insulation, terminations, contact orientation at each end and connector locking mechanisms vary by product. Minimum bend radius and suitability for repeated flexing require individual confirmation.
Explore flexible flat cables (FFCs) and functional adhesive films from 禾惠电子, part of the LEARY（莱尔科技） group. FFCs combine thin insulation and flat conductors to connect boards or boards and modules. EIKO reviews the application, drawings and specifications to check product candidates, samples and sourcing conditions.
About LEARY
LEARY（莱尔科技） develops, manufactures and sells polymer and electronic materials, including hot-melt adhesive films. Its range extends from bonding and insulating materials for FFCs to high-frequency transmission and shielding materials. Group company 禾惠电子 produces FFCs. EIKO reviews candidates from both the material and interconnect perspectives to suit the application.
Display FFCs (LVDS / VBO)
For connections in televisions, LCD displays and automotive display equipment. Candidates are reviewed against signal format, conductor count, length, termination, connector pairing and characteristic-impedance requirements.
SATA and High-Frequency / High-Speed FFCs
Candidate wiring for PC-related equipment, servers and video devices. We check SATA, VBO or other interface requirements, transmission conditions, shielding, crosstalk and loss-evaluation criteria. Support for a particular speed or standard requires individual confirmation.
Automotive FFCs
Candidate wiring for vehicle displays, doors, seats, roofs and ADAS-related equipment. We review mounting space, flexing, temperature, vibration, humidity and required automotive evaluation for each product and assembly. Safety-related functions require separate suitability checks.
Battery Signal-Collection FFCs (CCS-Related)
For signal-collection wiring in lithium-ion and energy-storage battery modules. We review cell layout, signal count, connection method, insulation and module mounting. The role is assessed separately from main-current wiring and busbars.
Functional Adhesive Films
Options include hot-melt adhesive films for FFCs, high-frequency/high-speed transmission films and adhesive films for glass-manufacturing processes. Candidates are reviewed against bonded materials, layer structure, insulation and dielectric requirements, and lamination conditions.
Materials for High-Frequency Signal Transmission
In addition to finished FFCs, discuss materials for insulation, bonding and shielding. Material and cable constructions are reviewed for internal wiring in large displays, laptops and servers.
LEHS Series High-Frequency Adhesive Films
Films combining a PET substrate with a polyolefin hot-melt adhesive. Candidates for USB 3.0/3.1 and large-display FFC applications where low dielectric constant and low dielectric loss are priorities. Selection considers frequency, bonded materials, film thickness and lamination conditions.
Integrated Adhesive and Shielding Materials
Composite materials combining adhesive and shielding layers, allowing FFC bonding, insulation and shielding to be considered together. For reviewing separate shielding-lamination steps or signal quality over longer wiring, we check grounding, layer construction, impedance, and loss and crosstalk evaluation conditions.
Adhesive Films and Shielding Materials for PCIe 4.0 Applications
Materials to evaluate for FFC-based high-speed internal wiring in servers and similar equipment. Film and shielding combinations are reviewed against cable length, connectors, required impedance, insertion loss and crosstalk. A material alone does not guarantee compliance of a finished cable.
Halogen-Free High-Frequency Films
Candidates where laptops, televisions or other equipment require halogen-free specifications. For high-frequency hot-melt adhesive films using PI substrates and integrated materials, halogen limits, flammability test methods and scope, and temperature requirements are checked for each product.
Dielectric properties depend on measurement frequency, method and material construction. Transmission performance is evaluated on the finished cable and its connections; comparative chart values are not universal guarantees. The PCIe 5.0 adhesive film is described as under development and is not included as an available product.
Automotive FFC Adhesive Films: Selection by Application
Separate from the applications of finished automotive FFCs, adhesive films for bonding conductors and insulation are selected according to the installation location and manufacturing process.
Moving Wiring
Adhesive films for FFCs that follow movement in clock springs, power windows and power seats. Share bend radius, motion direction, cycle requirements, operating temperature and layer construction so that adhesive durability and flex-test conditions can be checked. Safety-related locations require separate qualification of the finished component.
Battery-Module and Sensor Wiring
Candidate bonding and insulating materials for battery-module signal collection, sensor wiring and centre control panels. We review temperature, humidity, long-term conditions, conductor adhesion, insulation requirements and adhesive squeeze-out. These functions are considered separately from main-current battery wiring.
Wiring in High-Temperature Locations
For connections and sensor wiring in hot environments, constructions such as PPS substrates combined with heat-resistant PU may be considered. Products are checked against continuous temperature, short-term peaks, low-temperature conditions, damp-heat and thermal-ageing tests. These are distinguished from separate heat-resistant grades described as under development.
Terminations Requiring High-Temperature Soldering
For FFCs undergoing soldering, a PI substrate and thermosetting adhesive-film construction may be considered. We check soldering temperature, duration and cycles, termination design, adhesive curing, and post-process delamination and insulation evaluation. Process heat resistance is assessed separately from continuous service-temperature capability.
Temperature capability, flex life, flammability and automotive suitability are checked for each product, construction and test condition. Comparative test values are not universal guarantees, and products under development are not included as available products.
Materials for Reinforcement, Insulation and Noise Control
FFC Termination Stiffeners
Materials for reinforcing FFC ends inserted into connectors and adjusting termination thickness. Candidates are checked against end geometry, required thickness and stiffness, lamination temperature and mating connectors.
PI Coverlay
Polyimide-based cover materials for protecting and insulating flexible-circuit conductors. We review circuit construction, openings, flexing, bonding and temperature requirements to check suitability for the specific product.
Electromagnetic Absorbers and Electronic Shielding Films
Materials to evaluate for noise control in electronic equipment and LVDS wiring. Absorption and conductive shielding are considered as distinct functions. Selection considers frequency, placement, grounding, thickness, processing and lamination. Noise-reduction performance must be verified in the actual equipment.
Discuss Your Wiring and Lamination Requirements
In addition to standard FFC dimensions, share whether the wiring is fixed or moving, bend locations and repeated-flex requirements, contact orientation and stiffeners, shielding and grounding, and the mating connector. Cell layouts and connection drawings help with CCS enquiries; layer materials and lamination processes help with adhesive-film enquiries.
Construction, specifications and suitability vary by product. Transmission speed, temperature capability, flex life, flammability performance and certification scope must be checked for the product and test conditions concerned. Stock, samples, minimum quantity, price and lead time are confirmed individually. Unconditional interchangeability or performance improvements are not guaranteed.

Industrial Sensors and Precision Measurement Devices
Choose Sensors by What You Need to Know
Start by distinguishing presence detection from dimensional measurement to narrow down suitable candidates.
01
Is an object present or passing?
Through-beam example
Emitter
Receiver
Box
Check box arrival or part passage
Photoelectric or fiber-optic sensors
Example result: present / absent
Through-beam sensing uses interruption of light; reflective sensing uses changes in returned light. Transparent targets and surface conditions require suitable sensing methods.
02
Has a metal part approached?
Inductive proximity example
Sensing zone
Sensing face
Metal
Check metal-part arrival or machine-part position
An inductive proximity sensor example
Example result: in range / out of range

03
How much has distance or height changed?
Distance / height measurement
↕ d₁
↕ d₂
Reference
Measure step height, surface position or dimensional change
Displacement sensors and measuring devices
Example result: a distance or displacement value
Optical, contact and other methods are selected for the application. Thickness measurement requires verification of the measurement setup, including references and sensor arrangement.

Typical Applications
Application examples help narrow down the sensing method and measurement setup. The appropriate method depends on the target material, transparency, surface condition, speed and installation environment.
- Precision measurement in electronics and semiconductor production: candidate applications include step height, wafer bow, bump profiles, glass or transparent-material thickness, and coating thickness. We review laser displacement, confocal, white-light interferometric or reflectometric thickness methods against the target and measurement conditions.
- Film processing and transport: examples include film meandering or sag, and electrode-tab position or missing-tab detection. We clarify whether the required measurement concerns lateral or vertical changes, then review sensor arrangement and method.
- Photovoltaic production: examples include glass thickness, silicon-ingot dimensions, single-sheet versus overlapping-cell detection, and module presence or positioning. These are distinct from lithium-ion battery material applications. Optical, ultrasonic and other candidates are reviewed for the process concerned.
- Logistics and warehouse equipment: examples include arrival detection, distance measurement and positioning for AGVs, shuttles or stacker cranes, and 1D/2D code reading. Optical communication between equipment can also be reviewed against distance and interface requirements.
