چکیده

Abstract The electronic industry has room for improvement in adopting cleaner strategies, both production processes (often energy-intensive and polluting) waste management. Many small components like security tags are routinely disposed of via general waste, which could be reduced biodegradable polymers. In this work, a method selective deposition metallic micro-tracks on polycaprolactone (PCL) circuitry integration is presented. polymer biodegradable, flexible, suitable 3D printing, can obtained from sustainable sources. Photoreduction Ag ions was used to generate seeds subsequent electroless copper (Cu) plating process that avoids common but undesirable compounds such as cyanides palladium. Two different photopatterning methods were successfully achieve Cu plating: flood exposure with 460 nm light-emitting diode (LED) direct laser writing (DLW) using 405 laser, achieving 47 ± 11 ? m wide tracks. uniform layers PCL substrates demonstrated, thicknesses up 14 electrical conductivities 2.06 × 10 7 S ?1 , near the conductivity bulk (5.89 ). Cu-plated interconnects demonstrated fully functional powering 5 SMD LEDs circuit. Furthermore, DLW enabled interconnect manufacturing an uneven substrate. This selective, low-cost, vacuum-free minimized environmental impact, it provides new route towards electronics.

Electroless Nickel Plating with Hypophosphite

In the previous chapter, the components of electroless nickel plating baths were discussed from the viewpoint of the function each performs in the bath, with little attention paid to their effect on the plating process. The metal and the electron source (the reducing agent) are consumed in the electroless plating reaction and so their concentrations in the bath are continuously decreasing. Ther...

Electroless Nickel Plating: Bath Control

In this paper, bath control is proposed for the electroless nickel plating through holes board process. The main parameters of the product (board) – thickness of the plating film and phosphorous content – are stabilized at constant levels using optimal tracking control. The set point for control is calculated from the model in dependence on the current state of the process. The pH-index and nic...
