CIC holds a suite of certifications, including ISO 9001, IATF 16949 (for automotive), and ISO 13485 (for medical), reflecting their commitment to meeting industry-specific standards. They also offer value-added services like laser marking (to identify coated PCBA with serial numbers) and custom packaging, making it easier for clients to integrate the coated assemblies into their final products. While CIC's focus on mass production means they have a higher MOQ (500 units) compared to some competitors, their economies of scale result in lower per-unit costs—making them ideal for businesses with established product lines and consistent demand.

Fomboni Precision Molding (FPM) is a boutique supplier based in Fomboni, the capital of Mohéli, specializing in low volume and prototype PCBA low pressure injection coating. Founded in 2016 by a former aerospace engineer, FPM caters to startups, research labs, and small-batch manufacturers who need high-quality coating for innovative, one-of-a-kind projects.

What makes FPM unique is its flexibility with custom molds. Unlike larger suppliers that require clients to use standard mold sizes, FPM designs and 3D-prints custom molds in-house, often within 24 hours of receiving a PCBA design file. This allows clients to test different coating geometries and materials without the high upfront costs of traditional mold tooling. FPM's team works closely with clients during the design phase, offering feedback on how to optimize component placement for better coating adhesion and protection—an invaluable service for first-time product developers.

FPM uses a range of advanced coating materials, including conductive and EMI-shielding options for clients working on sensitive electronics like military communication devices. They also offer low pressure molding for electronics with complex shapes, such as curved PCBA or assemblies with protruding components. While FPM's lead times are longer for custom projects (typically 3–5 days for prototypes), clients appreciate the personalized attention: each project is assigned a dedicated engineer who oversees everything from mold design to final testing. For businesses in Comoros looking to innovate without breaking the bank, FPM's prototype-friendly approach is a perfect fit.

Comoros Green Tech (CGT) is on a mission to make electronics manufacturing more sustainable, and their low pressure injection coating services are a reflection of that goal. Based in Moroni, CGT uses 100% renewable energy (solar and wind) to power its facility, and all waste from the coating process is recycled or repurposed. This commitment to the environment has made them a preferred partner for international brands with strict ESG (Environmental, Social, Governance) goals.

CGT's coating materials are sourced from European suppliers that prioritize sustainability, with options like plant-based polyols and recycled polymers. Their low pressure injection coating process is designed to minimize material waste, with precision dosing systems that ensure only the necessary amount of coating is used for each PCBA. The company also offers a "take-back" program, where clients can return used or defective coated PCBA for recycling—a service that aligns with circular economy principles.

Beyond sustainability, CGT delivers on quality. They are RoHS compliant and hold ISO 14001 certification for environmental management, and their coatings are tested to meet IP68 standards for dust and water resistance. CGT's client base includes European consumer electronics brands and local solar energy companies, who value both their green credentials and technical expertise.
