Introduction
Yin Yang board, also known as mirror board, refers to two types of panel designs in PCB (printed circuit board) manufacturing: one is a panel with the front and back reversed, that is, one side of a PCB is spliced together with the other side of another; Another way is to have all the panels on the same side but upside down. This design aims to improve the efficiency of SMT (Surface Mount Technology) production lines, reduce idle time by optimizing layout, and effectively increase board utilization, saving costs. Yin Yang boards are widely used in electronic assembly to achieve more efficient production and cost control
Advantage
In the electronic assembly manufacturing industry, there are generally two types of 'MirrorBoards' that we refer to. The first type is a different side reversed yin-yang board
Mirror board is also a situation where the first side of one board and the second side of another board are presented on the same side of the panel; Another type is a yin-yang board where all the panels are on the same side but reversed left and right (Same)
Side mirror board, such as the layout of PDPD.
There are two reasons why electronic manufacturers may require the use of a Yin Yang board design:
We can fully utilize the advantages of SMT long lines to achieve greater efficiency in component production
The overall efficiency of an SMT line can be judged simply by checking if there are machines idle. If it is possible to achieve a time without machine idle, then we can say that the efficiency of this SMT line has reached 100%.
But is it really that simple to achieve 100% efficiency? With the increasing speed of SMT machine parts, SOC (System On Chip)
Parts are becoming increasingly popular, and there are fewer and fewer parts on a single board, but we haven't seen solder paste printing machines yet
Machine has made significant progress in speed, so many SMT lines now face bottlenecks in the solder paste printing machine, which means that the solder paste printing machine cannot rest while other more expensive machines are waiting in vain.
It can save the wasted space of empty boards by improving the efficiency of panel assembly and saving costs.
