Sanitation reflects the responsibility of plant manager directly. You may say the quality of products is not determined by the workshp sanitation, but if with good sanitation condition, workers and staffs will be more comfortable when they produce or assembly your products.At same time, if the rights of worker are guaranteed well, to some extent you can trust this supplier more because they pay attentions to something others not only profits.

If the workshop is full of PCBs and workers are really very busy to finish the assembly works, it's obvious that this factory has no other unused business capacity right now. When you start to cooperate with this PCB Assembly factory, you should pay more attention to the lead time. Otherwise, your orders will be delayed because of backward production capacity.


For international business, packaging is actually the first impression you give to your customer if they didn't visit your factory before. PCB or PCBA products are electronics related, if not with antistatic and stable packaging, no one can predict what will happen during such long time and long journey transportation. The products will be useless if they are damaged or defected when arriving the customers' place, even though you can say you tested 100% well before delivery.
