6. Q&A
Q: What’s the difference between DFN2.5×1 carrier tape and ordinary carrier tape? Why must we use the special one?
A: The core difference lies in “compatibility + precision”! DFN2.5×1 is an ultra-thin and ultra-small package. The cavity size and depth of ordinary carrier tapes do not match at all, which is prone to device shaking, jamming, dropping and placement deviation, directly reducing production line yield and increasing device loss cost. Our DFN2.5×1 special carrier tape is completely customized 1:1 for DFN2.5×1 packaging, with exclusive optimized cavity size, depth and draft angle. The device fits tightly when put in, and the placement is smooth without mistakes, fundamentally solving all compatibility pain points and maximizing the production line efficiency.
Q: Why choose new black PC material instead of traditional PS?
A: Because new black PC material is the “ceiling” of ultra-thin device carrier tapes! Compared with traditional PS, PC material is comprehensively superior in toughness, heat resistance and impact resistance, no whitening or breaking during winding, and has a wider temperature resistance range, which can withstand both high-temperature workshops and low-temperature storage. Moreover, the black material has strong light shielding property, which can perfectly protect photosensitive IC devices from light affecting performance and lifespan. It can be easily adapted to ordinary consumer electronics, as well as automotive-grade and industrial-grade high-end scenarios, making it more worry-free and reliable to use.
Q: What is the cost-effectiveness of Hatro’s carrier tape?
A: As the most cost-effective comprehensive carrier tape source manufacturer, Hatro relies on self-developed high-speed particle molding machine to subvert traditional technology and reduce costs by 30%. At the same time, with automotive-grade quality and micron-level precision, it provides customers with mid-to-high-end positioning at affordable prices, coupled with one-stop service, truly achieving “no discount on quality, significant cost reduction” and full cost-effectiveness.
Q: Can you provide matching cover tape and reel? Can they be provided as a one-stop solution?
A: Sure! Relying on the advantages of the full industrial chain, we directly provide one-stop supporting services of carrier tape + cover tape + reel. 8mm cover tape and full-spec reels can be perfectly matched with DFN2.5×1 carrier tape. You don’t need to contact multiple suppliers, and you can purchase all at one time, which is worry-free and efficient. It also avoids the problem of mismatched products from different suppliers and greatly improves the production line connection efficiency.
