12.5 Advanced Technology | Button-Plating

Features & Benefits

• Metallization of drill holes without additional copper build-up in the layout
• More precise structuring possible, as the base copper is very thin (5...10µm)
• Avoids excessive base copper thicknesses during multiple metallization of drill holes

Disadvantages

• Higher costs compared to standard technology due to additional photo printing and electroplating processes
• Layout may exclude the use of button plating (residual ring width too small)
