 What is a HDI PCB?
  
 IPC-2226 defines HDI as a printed circuit board with a higher wiring density per unit area than conventional printed circuit boards (PCB). They have finer lines and spaces ≤ 100 µm / 0.10mm, smaller vias (<150 µm) and capture pads <400 µm / 0.40mm, and higher connection pad density (>20 pads/cm2) than employed in conventional PCB technology.

 Our mission:
  
 PCBs for demanding customers, on time with zero defects, produced sustainably at the lowest total cost. Manufacturing many different types of PCBs in smaller series (High-mix, Low-volume) involves constantly adjusting, adapting and problem solving.
  
 Our responsibility:
  
 We know that the PCB is a critical key component for our customers. And we know for sure that anything can happen during the complex production process involved – and it often does. In our world, taking full responsibility means a lot of things, including a responsible and sustainable approach in everything we do – socially, environmentally and ethically. When a problem occurs, we try as hard as we can to understand the problem and find a solution. Our mindset is that we own the problem and don’t leave until we have cleared it up.
