Description
Technical Field
[0001] This utility model relates to the field of blister tray technology, specifically a limiting blister tray for large-size printed circuit boards. Background Technology
[0002] In the electronics manufacturing and logistics sector, the protection and efficient handling of large-size printed circuit boards (PCBs) remain critical issues. Traditional packaging methods, such as cardboard boxes, wooden pallets, and ordinary plastic pallets, are no longer sufficient to meet the diverse demands of modern electronic products for safety, convenience, and efficiency.
[0003] While cardboard boxes are inexpensive, they lack strength, are easily deformed and damaged, and cannot stably support large PCBs, potentially causing the circuit boards to bend. Wooden pallets are strong enough, but they are bulky, take up space, and the wood is prone to warping and insect infestation, requiring frequent replacements, making them uneconomical. Ordinary plastic pallets are lightweight and durable, but lack support mechanisms, making it easy for large PCBs to wobble and shift, and they are also susceptible to damage from vibrations during transport, affecting performance and quality.
[0004] Furthermore, traditional pallets present numerous inconveniences when handling large PCBs. Operators must expend considerable effort and carefully adjust the angle and position to remove them from the pallet, which is not only inefficient but also prone to causing damage to the edges of the circuit boards during handling, potentially leading to component damage or circuit breakage, resulting in additional economic losses for the company and potential risks due to delayed delivery.
