The ink jet technology is used to spray metal particles to overcome this problem, and the lines can be formed without using an image transfer process and an etching process, thereby simplifying the manufacturing process. With conventional manufacturing techniques, the mask used in the image transfer manufacturing process must be changed when the shape of the circuit is changed, which not only increases the time and cost for mask fabrication, but also requires changes in the type of printed circuit board or the manufacturing line.

Meanwhile, the excessively soft plate body can also cause instability of each electrical element plugged on the plate body.
