The carrier tape is sealed with the upper cover belt. It is to complete the packaging function as the basis of turnover materials for electronic devices. However, as the packaging of SMD electronic components, it also plays an irreplaceable role in other general turnover materials. Such as antistatic function, humanized packaging function and load-bearing transportation function.—carrier tape seal crack
It is precisely because of this effect that there are many restrictions on the raw materials for the production of these two commodities and many problems. As the title says, “the problem of sealing and cracking of carrier tape”. But this problem is not inevitable. If the method is appropriate and the application is appropriate, we can not only consider the role of turnover materials for SMD electronic devices, but also apply them safely without concern.—carrier tape seal crack

In the final analysis, the problem of sealing and cracking of the carrier belt is caused by the mismatch between the carrier belt and the upper cover belt. Let’s first talk about the basic raw materials of these two commodities. The general raw materials of carrier belt are PC, PS, ABS, etc. The basic raw material of the upper belt is pet. The raw materials carrying the tape are not compatible with the raw materials on the tape because the organic chemical composition is different or the melting point is different. Of course, it is not easy to stick, or cause too tight and too loose. It is too light or too heavy that will cause adhesion and separation, and the provisions of upper belt separation cannot be incorporated. In order to consider the matching between the upper belt and the carrier belt and achieve a certain kind of practical effect, organic chemical preservatives must be penetrated into the production and manufacture of the upper belt or integrated with some chemical materials.—carrier tape seal crack

Because different manufacturers produce tape carrying raw materials, when producing tape carrying raw materials, different practical effects will appear when bonding with a certain kind of tape due to different secret recipes, various chemicals and different habits or hobbies such as conductive particles. Therefore, we have always paid attention to that different upper belts cannot be matched and bonded with any kind of carrier belt. Moreover, the packaged components are different, and the separation range after bonding must be considered. You can’t say the same thing. The only way is to match it according to the experiment. Find the specifications and models of the two products that can be matched, and find the appropriate sealing standard.

Therefore, it is necessary to deal with the problem of sealing and cracking of carrier tape. It is necessary to ensure that the two commodities are tested, and the high and low temperature tests are carried out at different times under different environmental factors and standards. And ensure the uniformity of the upper cover belt and download belt after testing and the variability of the sealing standard.
