Frequently Asked Questions

What is High-Throw DC plating?

High-throw DC plating is a direct current acid copper plating process that offers superior throwing power, enabling uniform copper deposition in deep or complex features, such as through-holes with high-aspect ratios, without the need for pulse plating equipment.

How does High-Throw DC improve plating performance?

High-throw DC solutions, such as MacuSpec HT 360, plate copper with exceptional brightness, ductility, and uniformity across a wide range of current densities. This results in improved throughput, broader operating windows, and reduced surface copper build-up, making it ideal for advanced printed circuit boards (PCBs).

What current densities can be achieved with High-Throw DC plating?

High-throw DC plating solutions, like MacuSpec HT 360, allow current densities from 5 to 30 ASF. This range provides flexibility in plating thick copper layers and complex geometries while maintaining high throughput.

How does High-Throw DC compare to pulse plating?

High-throw DC plating delivers performance comparable to pulse plating, particularly for complex designs, without the need for additional pulse rectification equipment. It offers superior throwing power, ensuring uniform plating in deep or high-aspect ratio holes.

What aspect ratios can High-Throw DC plating handle?

High-throw DC plating can handle aspect ratios of up to 15:1, ensuring effective copper deposition in deep vias or holes. This makes it an ideal solution for fabricators working with advanced multi-layer boards or High Density Interconnect (HDI) designs.
