Light Pressure / Conductive Pattern

The Auto Cutting Sheet Laminator from Hakuto adds a photosensitive resist to the printed circuit board. The layout is then formed into the resist via exposure to ultraviolet light. Hotoprint uses high-precision UV-exposure systems such as the Schmoll MDI Printer with UV-LED. This system works with over 2 million individually controllable micro mirrors and powerful UV LED's.


      

Structures such as conductive pattern or spaces are not exposed. These areas are developed in further process. The bare copper forms the basis for the electroplated design of the layout.

For excellent exposure results, the climate needs to be constant. At Hotoprint, an air conditioning and purification system permanently regulates the temperature, the humidity and dust.
