PCB News - PCB installation requirements

It should be supported at least within 1 inch of the three edges of the PCB board. According to practical experience, the distance between the support points of a PCB with a thickness of 31---62 mils should be at least 4 inches; for a PCB with a thickness greater than 93 mils, the distance between the support points should be at least 5 inches. Taking this measure can improve the rigidity of the PCB and eliminate the possible resonance of the 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 PCB design.
4) When the plug-in tool is to be used in the equipment, especially its size should be considered.
5) A plug-in device is required, which is usually permanently fixed to the PCB assembly with rivets.
6) In the PCB mounting frame, special design such as load bearing flange is required.
7) The adaptability of the plug-in tools used to the size, shape and thickness of the 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, it is required to have access to the inside of the equipment to a certain extent.
