We review your Bill of Material and create a custom solution specific to your cost objectives. Our advanced material planning solutions allow us to make real-time scheduling decisions to mitigate both our liability and yours.

Manufacturing Capabilities

We offer a broad range of manufacturing capabilities from simple single sided assemblies to complex densely populated fine pitch and BGA surface mount assemblies. At Green Circuits we have designed each of our manufacturing lines to achieve maximum performance in various technology sectors. While the lines are customized, we chose common equipment platforms to allow efficient New Product Introduction and rapid transfer to production. We offer high level assembly or box build with various supply chain solutions. Our products can go from your dock to stock or we can provide drop shipment direct to your customers. Whether you have high-mix, low-volume supply chain problems or cost pressures for higher volume product Green Circuits has a solution to make you successful.
