每个电子制造商，无论是原始设备制造商（OEM）还是电子制造服务（EMS）公司，都必须确定进入装配过程的未填充印制板是否具有足够的清洁度。“多干净才算足够干净？”这是一个没有明确答案的问题，因为董事会清洁度没有“黄金数字”。这个问题是一个非常复杂的话题，有许多关键的考虑因素，因此不存在确定可接受性的单一方法。认识到这一点，IPC-5702旨在为印制板或印制板组件专业人士提供一些指导，指导他们如何将清洁度相关数据与电气功能关联起来，并确定“可接受”的清洁度水平。

Every electronics manufacturer, whether an original equipment manufacturer (OEM) or electronics manufacturing services (EMS) company, must determine if the unpopulated printed boards entering the assembly process have an adequate level of cleanliness. The question of "how clean is clean enough?" is one that has no definitive answer, as there is no "golden number" for board cleanliness. The issue is a very complex topic, with many critical considerations, and so a single methodology to determine acceptability does not exist. Recognizing this, IPC-5702 has been written to give the printed board or printed board assembly professional some guidance on how to correlate cleanliness related data to electrical function and determine "acceptable" cleanliness levels.
