Dry method for PCB

De Montfort University Leicester (DMU) academics are taking part in the Laser Printed Electronics (LPE) two-year research project aimed at providing an environmentally friendly production method for pcb manufacturer.

U.K. researchers are exploring whether laser technology can provide a low-cost, chemical-free method of making printed circuit boards.

The project is developing a dry printing method that uses no chemicals. DMU’s Rapid Prototyping and Manufacturing Group, led by Professor David Wimpenny, will develop a deposition system based on a combination of laser printing and fibre laser consolidation of the deposited material.

The project will initially look at laying conductive tracks on the circuit boards but could also be used to deposit layers of dielectric or protective materials, solder for connection of devices and also to print legends on boards.
