Mara tape, also known as silicone mara tape, fire cow tape, mara tape, is a polyester film (PET Film) as the substrate coated with acrylic polymer pressure-sensitive adhesive made of high temperature and high pressure flame retardant insulating tape, thickness of 0.1mm or so, for the single-sided adhesive tape, is widely used in the electronics industry insulation, such as transformers, motors, capacitors and other types of motors, electronic components of the insulating wrapping, but also can be used for Lithium battery wrapping, such as in the protection plate and the core between the wrapping to play a role in fixing and insulation and fire protection.
Nowadays, the electronic industry material anti-counterfeiting traceability system has been popularized, in the electronic components of the outer layer of the surface of the Mala tape marking is commonplace. In the past, the main use of traditional labeling or fully automatic inkjet printer to mark the way, the shortcomings of the two is that, with the growth of years, coupled with the high temperature environment, the label is easy to fall off resulting in safety hazards, or the spray code is prone to become fuzzy and unclear, losing the significance of the anti-counterfeiting traceability.
The use of laser marking is more advantageous. It is through the high energy density beam directly on the surface of the object instantaneous vaporization and become a permanent mark, can not be erased, and no consumables, high marking efficiency.
Can be used for marking a wide range of laser categories, for the characteristics of polyester film, with "cold processing" 355nm UV nanosecond lasers (5W) in the laser marking of Mala tape in the application of the scenario, proper!
355nm UV single photon energy is high, with a pulse width of 25ns, the heat-affected zone is very small, to a large extent, to reduce the thermal deformation of the material; its beam quality is high (M2 <1.2), the spot diameter after focusing is very small, can reach 10um or so, can be some small electronic components on the marking text, graphics, images, barcodes, two-dimensional code, the product number, autographs, clear boundaries, easily realized! ......, the boundary is clear, easy to realize the identification and traceability of one thing, one code; at the same time, the high flexibility of laser marking for some special shapes of components can also be easily marked, and really realize the greater value of the marking.
