Why do PCB production do panelization?
The general circuit board production will carry out the so-called panel operation, the purpose of which is to increase the production efficiency of the SMT production line.
PCB usually has so-called "several in one" boards, such as two-in-one (2 in 1), four-in-one (4 in 1)...etc.
If you have the opportunity to walk on the SMT production line, you will find that the biggest bottleneck of the SMT production line is actually the solder paste printing process, because no matter how big the PCB is, the printing time is almost 25 seconds or so, that is It is said that if the time spent by the higher unit price of the high-speed patch printer and the general-purpose patch printer is less than that of the solder paste printer, it will be idle. From the point of view of economic benefits, this is a kind of waste.
In fact, the speed of the placement machine is very fast, as fast as one second, several parts can be printed, and some placement machines even have several nozzles that can be printed at the same time. Judging from the number of parts on the current mobile phone PCBA, if there is only a single For a board, it should take less than 10 seconds to complete all the placement operations, so the PCB is assembled to increase the number of parts for placement, which can increase the utilization rate of the placement machine and improve efficiency. Of course, it's best to balance the line so that each piece of equipment is fully functional.
PCB jigsaw has another advantage. It can save time when picking and placing PCBA, because multiple boards can be picked and placed at the same time at one time. If the subsequent board level test can be done with the board test, it can also greatly save the board in the fixture. Man-hours wasted in pick and place.
Finally, some boards have irregular shapes when they are designed, such as this board. If it is made into "Plan 1", there will be a piece of scrap in the upper left corner. If it can be designed to be upside down and upside down. PCB, waste can be greatly reduced, this is the concept of improving the utilization rate of PCB board.
BQC will decide whether to make panels according to customer needs, help customers save costs, and improve our production efficiency
