Substrates are precisely aligned to improve assembly yield. Therefore, the PCB substrate carrying structure must have high reliability, that is, its structure must be stable, strong, and not easily deformed, and it must be able to place and arrange the plurality of PCBs accurately. In addition, the PCB substrate supporting structure also needs a high degree of freedom to be able to carry PCBs of different sizes, and other considerations such as selection of low-cost materials and easy fabrication are also considered.
