Tape&moistureproof film 

All PCBA cartons were taped completely, which avoid cartons damage or wetting during transportation. For air and sea transportation delivery, we also add moistureproof film all around goods.

Carton label

We have clear labels stick outside all cartons with part number, quantity, weight and date information. From prototypes order to big volume productions order, every shipment was treated carefully with labels. The cartons gross weight normally controlled as 15-17KG which ensure the merchandise safety and avoid transportation damage.
