High-performance processing components and specialized electrical assemblies engineered to thrive in demanding tropical industrial environments across the Philippines.
The industrial landscape of the Philippines is undergoing a rapid transition towards renewable energy generation, modern electric mobility (such as jeepney electrification projects), and expanded telecommunications across its vast archipelago. From the bustling industrial corridors of the CALABARZON region to green-field utility-scale solar farms in Central Luzon and new data center installations in Metro Manila, the demand for robust, high-performance electronics has never been higher.
However, operating electronic devices in the Philippines introduces severe environmental constraints. High ambient temperatures, high relative humidity levels, and coastal salinity place tremendous physical stress on circuit boards. Standard printed circuit boards (PCBs) carrying high electrical currents easily fail due to thermal overload and delamination under these tropical conditions.
Thick copper PCBs (also known as heavy copper PCBs) have emerged as the standard solution to these challenges. By incorporating copper weights ranging from 3 oz/ft² up to 20 oz/ft², these specialized boards allow high currents to flow efficiently while minimizing heat generation, protecting critical systems from catastrophic failure, and drastically extending the operational lifespan of power electronics.
Under the IPC-2152 standard, managing current-carrying capacity while controlling thermal rise is critical. Heavy copper circuits act as integrated heat sinks, directly facilitating heat transfer away from high-power components.
Heavy copper traces allow PCBs to carry hundreds of amperes without overheating, eliminating the need for bulky external bus bars and reducing overall system dimensions.
By combining thick copper traces with high-thermal conductivity substrates, heat is spread uniformly, reducing local hot spots and thermal stress on sensitive semiconductors.
Thicker copper plating increases the mechanical strength of plated-through holes (PTH) and connectors, preventing physical deformation under intense vibrational loads.

How our Thick Copper PCBs and Thermal Solutions are deployed across various Philippine commercial and industrial projects:
Deployed in massive solar installations across Luzon and Visayas, converting raw DC power from solar arrays to utility-grade AC power. Our heavy copper boards handle massive power transfers while resisting tropical humidity.
Supporting EV charging infrastructure in urban hubs like Makati and Quezon City. Heavy copper traces prevent trace degradation from cyclic high-amperage charging currents.
Powering remote cellular tower networks in the Visayan and Mindanao islands. High-thermal copper PCBs ensure operation under high atmospheric salinity and fluctuating voltage ranges.

Etching heavy copper is highly complex compared to standard boards. Over-etching or undercutting can reduce the active cross-sectional area of a trace, creating localized resistive bottlenecks. At Velmix, we employ advanced chemical etching processes combined with laser direct imaging (LDI) to maintain strict trace dimensional control.
Standard liquid photoimageable (LPI) solder masks may fail to sufficiently coat the steep vertical sidewalls of 3oz+ copper traces. Velmix uses customized, high-build multi-pass coating techniques to guarantee insulation coverage and prevent oxidation or electrical arcing under high humidity conditions.
Every high-power PCB undergoes strict thermal cycling and burn-in testing to verify the integrity of the copper-to-FR4 resin bonds, eliminating any risk of delamination or micro-cracks in plated vias during operation.
Find answers to the most common engineering and logistics questions regarding Thick Copper PCBs and Velmix services:
A thick copper PCB is defined as any printed circuit board with a copper cladding thickness exceeding 3 oz/ft² (approximately 105µm) in either the internal or external layers. Standard PCBs typically utilize 1 oz or 2 oz copper weights. Heavy copper boards can scale up to 20 oz/ft² (700µm) or more depending on high-current requirements.
In high ambient temperature zones like the Philippines, heat dissipation is difficult. Thicker copper profiles provide a larger cross-sectional area, reducing electrical resistance (I²R losses) and thermal generation. Furthermore, the massive copper structures act as heat conduits to spread thermal energy uniformly across the board, venting it through heat sinks and cooling fans.
For thick copper PCB prototypes, manufacturing takes 5 to 7 working days, with mass orders requiring 10 to 15 days. Shipping via express air courier (DHL/FedEx) to Metro Manila or Cebu takes 2 to 4 working days, while bulk sea freight orders take approximately 7 to 12 days to clear customs in Philippines ports.
