Double-Sided PCBs
At Epitome, with a unit dedicated to manufacturing double-sided PCBs, we exemplify quality, production standards and customer-centricity. Here’s more to our double-sided PCBs and its benefits.
- Robust and reliable manufacturing process.
- Same bath used to etch both sides at the same time.
- Increased surface area in the same-size-single-layer board due to the second layer of copper and vias in a double-layer board.
