As a specialized OEM/ODM manufacturer established in 2003, Dongguan Ravo Electronics Co., Ltd. supplies high-precision conductive silver traces, flexible polymer thick film (PTF) electronics, and custom membrane switch keypads to equipment manufacturers worldwide, including engineering partners serving Les Cayes and the broader Southern Department of Haiti. Conductive silver ink circuits represent the gold standard for human-machine interfaces (HMI), sensor arrays, and low-voltage interconnections due to their extraordinary electrical conductivity, cost-efficiency, and mechanical flex life.
Screen-printed conductive silver traces rely on high-purity silver micro-flakes suspended within thermo-setting or UV-curable polymer matrices (typically polyester or epoxy resins). When precision screen-printed onto thermal-stabilized polyethylene terephthalate (PET) film substrates and thermally cured, the silver particles sinter into a continuous metallic network. This network delivers sheet resistivity values as low as <0.015 Ω/sq/mil (0.025 mm thickness), ensuring minimal voltage drop across complex keypad matrices, capacitive touch pads, and thin-film Force Sensitive Resistors (FSR).
To ensure long-term durability in field deployments, every custom flexible circuit engineered at Ravo undergoes rigorous stack-up analysis during DFM (Design for Manufacturability) review. The underlying polyester film must withstand thermal drying processes up to 150°C without residual shrinkage, preserving trace registration tight within ±0.05 mm tolerances.

Les Cayes, a vital commercial port, agricultural hub, and coastal city in southern Haiti, experiences a tropical monsoon climate characterized by intense solar radiation, high ambient humidity, and saline sea air from the Caribbean Sea. Equipment deployed in Les Cayes requires resilient electronic components that resist corrosion, fungal growth, moisture ingress, and thermal cycling. Ravo’s custom OEM conductive silver trace solutions are tailored to meet the demanding operational conditions across primary regional sectors:
With Les Cayes expanding its reliance on decentralized microgrids and solar energy storage, solar charge controllers and hybrid power inverters require dust-proof, moisture-sealed HMI control panels. Our custom conductive silver trace membrane keyboards, combined with IP67 perimeter 3M 9448A adhesive gaskets, ensure uninterrupted switching performance for inverter status lights and push-button parameter configuration.
The Southern Department of Haiti is internationally renowned for vetiver oil production, sugarcane milling, and coffee processing. Essential oil distillation and agricultural machinery operate in wet, organic solvent-heavy environments. We supply custom silver ink membrane switches with solvent-resistant Polycarbonate (PC) and Polyester (PET) graphic overlays that protect internal circuitry against chemical splashes and dirt.
Maritime transport between Les Cayes, Île-à-Vache, and mainland ports demands saltwater-resistant interface controls. Our custom silver-ink pressure sensors and sealed capacitive keypad panels are engineered with anti-sulfuration carbon paste coatings, enabling long-term operation on boat telemetry displays, diesel generator controls, and reverse-osmosis water desalination plants.
Regional health centers and humanitarian mobile clinics serving the Sud department rely on portable medical monitors and satellite communications hardware. Ravo builds custom tactile metal dome keypads featuring silver-ink conductive matrix traces and integrated SMD LEDs, providing clear visual status feedback and crisp tactile response under emergency field conditions.
As industrial modernization accelerates across the Caribbean basin, local machinery builders, maintenance contractors, and electronic system integrators in Les Cayes are transitioning from legacy mechanical push-buttons to integrated flexible printed electronics. Key market drivers include:
Operating a 12,000 square meter state-of-the-art facility in Dongguan, China, Dongguan Ravo Electronics Co., Ltd. brings over two decades of specialized manufacturing expertise to global OEM clients. We provide end-to-end service—from initial schematic artwork optimization to high-volume screen printing, laser die-cutting, automated component placement, and 100% electrical testing.
Equipped with semi-automatic and fully automatic CCD registration screen printing lines capable of printing conductive silver ink lines with trace pitch precision down to ±0.05 mm.
Complete control over cutting dies, embossing molds, and screen preparation allows rapid prototype turnaround within 5 to 7 working days, backed by 7x12h technical support.
ISO 9001 certified manufacturing workflow with 100% Automated Optical Inspection (AOI), insulation resistance checking, circuit resistance measuring, and key actuation life cycle testing (up to 1,000,000 actuations).
We utilize certified RoHS and REACH compliant raw materials from industry-leading brands, including 3M adhesive tapes (3M 467MP, 3M 468MP, 3M 9448A), MacDermid Autotype PET film, and Henkel Acheson conductive silver inks.
Silver migration occurs when moisture and DC electrical bias cause silver ions to migrate between adjacent conductors. For humid environments like Les Cayes, we apply a micro-thin carbon conductive cap over the silver traces, utilize UV-curable dielectric crossover insulation, and incorporate full perimeter adhesive sealing (3M 9448A or 3M 467MP) to completely lock out environmental moisture.
We support both low-volume prototyping and mass production. Prototype samples can be produced from as few as 1 to 10 pieces. Standard mass production runs typical start at 100 to 500 pieces depending on layout size, graphic overlay complexity, and LED integration requirements.
Please provide your 2D mechanical drawings (DXF, DWG, PDF) and graphic overlay vector artwork (AI, CDR, PDF) along with key layout details, circuit schematic, pitch requirements, connector tail length, and operating environment specs. Our engineering team will return a comprehensive DFM review within 2 hours.
Yes. We utilize conductive silver epoxy adhesive bonding to mount ultra-bright SMD LEDs, resistors, and diodes directly onto flexible PET silver conductive traces, offering reliable visual indicator lights for control panels.
We pack all conductive flexible circuits and membrane switches in anti-static ESD shielding bags with desiccants and export-grade reinforced outer cartons. Shipping to Haiti is arranged via international express air freight (DHL, FedEx, UPS) for fast 5-7 day delivery, or air/sea cargo to Port-au-Prince / Les Cayes for larger production shipments.
We provide standard 2.54mm pitch female crimp connectors with locking housings, 1.0mm/1.25mm/2.54mm ZIF (Zero Insertion Force) plain tail terminations, and custom male pin headers engineered to mate directly with your host PCB.
