1. Packaging specifications: High TG edge copper-plated multi-layer PCB boards are packed in professional-grade hard packaging boxes that are resistant to vibration and impact. The interior is tightly packed with anti-static foam and shock-proof materials to ensure safety and product integrity during long-distance transportation. 2. Transportation method: Choose land transportation, air transportation or sea transportation according to customer needs and destination; domestic orders give priority to fast land transportation, and overseas orders decide on air and sea transportation allocation based on timeliness and cost-effectiveness. 3. Identification mark: Fragile goods and anti-static signs are clearly posted on the outside of each packaging box to ensure that couriers and customers can identify and handle it with caution. 4. Express delivery method: We maintain cooperative relationships with a number of well-known express delivery companies and provide standard or economical express delivery services based on the urgency and delivery requirements selected by the customer. 5. Protective measures: The packaging process of each batch of products is strictly inspected to confirm that the closure is intact and there is no leakage. All shipping boxes are sealed and moisture-proof and fixed with protective tapes. The PCB boards are placed flush to reduce vibration damage during transportation. 6. Shipping charges: Shipping charges are calculated based on customer order quantity, packaging weight and volume, and final destination. Bulk orders can enjoy freight discounts and logistics insurance services.
