Electric Connection Of Electric Components To Printed Circuits
(AREA)
Abstract
This invention relates to a V-shaped groove frame. It is utilized for resolving the problem of pre-baking in the solder resist process. Further, it employs the self-produced alignment tool of solder resist finish to solve the register problem because the discarded printed circuit board (PCB) may easily cause environmental protection problem. By means of this method, it takes advantage of discarded recyclable material. Moreover, the demonstration combines traditional with modern technologies. Eventually, it utilizes recyclable heat absorption and heat release of physics and chemistry.
