What difference for pcb and pcba in the save? |
|
|
PCB board should consider the storage conditions, mainly to meet the conditions for subsequent re-assembled, the electronic parts is not taken into account, but in the assembled circuit board, because it will contain electronic components concerns must be pay more attention. Usually most concerned is scraped, hit, crushing, and other things to avoid electrostatic damage. Therefore, unless special products, most of all PCB storage in a stacked manner, and will be asked to control temperature and humidity. Packaging will be asked to vacuum processing, and packaging will be put for desiccant pack, and the other will be asked to dont open if it is not in use .It is a general requirement, and other requirements may be mutually agreed upon. As for the circuit board assembly, the assembly must look at the size of the decision. Usually a large circuit board using tray slices, binning, batch load, and must avoid electrostatic damage during operation. Therefore, after the assembly of semi-finished components the unit price will be increase. |
