Other issues: components flip：

Cover tape ncover's solution：There is a gap between the traditional cover tape and carrier tape, so the thin components are easy to flip over or slide into the next cavity.There is no gap between the ncover and the cavity because ncover has a posted smoothly feature. The thin, light component will not flip and slide to the next cavity.

【ncover's films are volatile-mounted, and after taping, they are attached to the cavity so that the components do not flip over or slide into next door cavity.】

Inconvenient problem：It is less user-friendly, non-reusable and also inconvenient for a rework.

【temperature，Pressure diagram】

Cover tape ncover's solution： Once HAA cover tape is used, the surface will be damaged by high temperature and pressure, so the peel strength is very unstable if reusing or reworking.

Cover tape ncover uses PSA, no high temperature and pressure, so the peel strength is very stable if reusing or reworking.

【Pressure roll tapes ncover with aqueous PSA,.】

Carbon, VOC problem：Causing environmental issues.

【Heating causes VOC, power consumption.】

Cover tape ncover's solution：Manufacturing cover tape products lots of carbon because of lamination process, sealing with carrier tape products VOC.ncover is a brand-new type of transparent cover tape which features a revolutionary dispensing technique that applies Aqueous PSA to the glue-free CPP film during the taping process to the carrier tape. ncover significantly reduces carbon production and VOC closes to zero.

【Cover tape ncover structure】

Bad transparency problem：It is not easy to visually inspect.

【Opaque】

Cover tape ncover's solution：Glue effects transparency.The structure of ncover is a single layer CPP film with two strips of glue.

【Highly transparency rate is good for inspecting.】

Large range of peel strength problem：Large range of peel strength causes components to turn over or pop-off.

【Components turn-over】

【Different processing conditions need to be set with different carrier tape materials, and the surface of carrier tape is smooth or not will cause large peel-strength range.】

Cover tape ncover's solution：The range of peel strength is relative to tapes’ interface characteristics and flatness of the carrier tape surface. So, HAA cover tape has large peel-strength-range.

Cover tape ncover’s peel strength is decided by the tear strength of materials and will not be affected by the adhesion or carrier tape’s surface. In other words, the peel strength is very smooth and not be changed by aging.

【The thickness of easy tear line】

【Applied for all material carrier tape, the range of peel strength is within 10g.】

Adhesive left problem：Customers refuse to use it because glues on SMTs feeder.

【Glues on carrier tape’s surface, cover tape’s side.】

【Glues cumulate on SMTs feeder.】

Cover tape ncover's solution：Glues on PSA tape’s side will stick SMT’s feeder.Easy tear line makes the tape peeling on SMT effortlessly. Glue and film are on carrier tape’s surface. No glue on the film’s side because glue is dispensed 1mm from the edge of film.

【Cover tape ncover effect】

Tearing problem：This problem on SMT is always a concern when in high peeling speed.

Cover tape ncover's solution：Sometimes, the cause of tearing is the burr occurred on the edge of cover tape while slitting, or carbon deposited on the sealing knife damages the surface of cover tape.

A featured added easy tear line makes ncover peeling with carrier tape effortlessly. ncover uses PSA, no high temperature and pressure, no chance of carbon deposited.

【Peeling from easy tear line on SMT】

Breaking open problem：A certain kind of cover tape has to match specifically to the carrier tape in different materials (PS, PC or PET). Otherwise, this problem will show up.

【Anchoring】

Cover tape ncover's solution：The HAA cover tape is by heating up its adhesive layer (a thermoplastic), some adhered surfaces cannot be sealed because of incompatible interface.

Cover tape ncover’s PSA is mechanical interlocking with the adhered surface and can be matched with carrier tapes in all materials.

【Anchoring】

Broken：

【Cover tape bursts open】

Cover tape ncover's solution： PSA cover tape matches with PS, ABS, PET, PP carrier tape, it breaks open easily because of the shrinkaged PS, ABS, PET, PP. ncover's CPP film has great flexibility, can shrinkage with carrier tape.

【Cover tape ncover with PS carrier tape, aging condition is 80℃, 95%, carrier tape is deformation, ncover does not burst open.】
