Новости PCB - требования к установке PCB

It should be supported at least within 1 inch of the three edges of the PCB board. According to practical experience, расстояние между опорными точками PCB толщиной 31 - 62 мм должно составлять не менее 4 дюймов; для PCB толщиной более 93 мм, the distance between the support points should be at least 5 inches. принятие таких мер повысит жесткость PCB и устранит потенциальный резонанс PCB.

Certain PCBs usually need to consider the following factors before deciding which mounting technology they use.
1) The size and shape of the PCB.
2) Number of input and output terminals.
3) Available equipment space.
4) Desired ease of loading and unloading.
5) Type of installation accessories.
6) Required heat dissipation.
7) The required shieldability.
8) The type of circuit and its relationship with other circuits.

PCB allocation requirements
1) No PCB area for mounting components.
2) The influence of the plug-in tool on the installation distance between two PCBs.
3) Specially prepare mounting holes and slots in проектирование PCB.
4) When the plug-in tool is to be used in the equipment, особенно его размер следует учитывать.
5) A plug-in device is required, which is usually permanently fixed to the PCB assembly with rivets.
6) In the PCB mounting frame, нужно специальное проектирование, как несущий фланец.
7) The adaptability of the plug-in tools used to the size, форма и толщина PCB.
8) The cost involved in using plug-in tools includes both the price of the tool and the increased expenditure.
9) In order to fasten and use plug-in tools, требовать определенного доступа к устройству.
