What matters should be paid attention to in PCB puzzle?

PCB circuit board factory: Usually we often see the PCB splicing structure in the circuit board manufacturing enterprises, but the splicing method of the PCB circuit board, the number of splicing boards, etc. need to be determined by comprehensive consideration of many factors. Jigsaw is more conducive to saving production time and more effective use of machinery and equipment, effectively using the area of the board to reduce unnecessary cost waste.

Someone asked: How many unit boards should be included in a jigsaw puzzle. What I want to tell you is that this quantity problem needs to be determined according to the actual situation. In principle, the more the number, the better, the more the number, and a single PCB is in the track. The shorter the transmission loss time, the higher the utilization rate of the equipment; at the same time, the more the number of panels, the higher the utilization rate of the materials used in PCB manufacturing, and the cost will be reduced accordingly. Of course, this also has a limit. Sometimes with the increase in the number of panels, the material cost of the unit board will increase instead, which is mainly due to the limitation of the equipment capacity of the PCB manufacturer. Our common PCB assembly methods generally include ABAB or AAAA. The specific method of splicing needs to be determined by considering the density and distribution of electronic components on the PCB board and the configuration of the equipment, so no matter which splicing method has its own advantages and disadvantages.

The use of the outer frame of the PCB jigsaw should also be carefully considered to ensure that the PCB jigsaw will not be deformed after being fixed on the fixture. Generally, it is not allowed to open V grooves on this side. In the case of this, it will cause the coordinate positioning problem of the processing. There should be no connector protruding between the outer frame of the jigsaw panel and the inner small board, and the small board and the small board. If this happens, it will prevent the tool from separating after the welding is completed. In order to ensure the position and level of the detection board, we need to set more than three positioning points on the edge of the board. By optically detecting these three points, the reference coordinates of the entire processing and the levelness of the board can be obtained.

The above are some instructions on PCB jigsaw, I hope I can help everyone. iPCB is a high-tech manufacturing enterprise focusing on the development and production of high-precision PCBs. iPCB is happy to be your business partner.
