Mala tape, also known as silicone Mala tape, fire tape, Mala tape, is a high temperature and high pressure flame retardant insulation made of polyester film (PET Film) as the base material and coated with acrylic polymer pressure-sensitive adhesive. Adhesive tape, with a thickness of about 0.1mm, is a single-sided tape. It is widely used in the electronic industry for insulation, such as transformers, motors, capacitors and other types of motors and electronic components. It can also be used for lithium battery wrapping, such as in protection The wrapping between the board and the battery core plays the role of fixation, insulation and fire prevention.
Nowadays, the material anti-counterfeiting traceability system has become popular in the electronics industry, and it is common to mark the surface of the Marathon tape on the outer layer of electronic components. In the past, labeling was mainly done by traditional labeling or automatic inkjet printers. The disadvantage of both methods is that with the increase of age and high temperature environment, the labels are easy to fall off, causing safety hazards, or the inkjet printer is easy to inkjet. It becomes unclear and loses the meaning of anti-counterfeiting and traceability.
Using laser marking has even more advantages. It is formed by instantaneous vaporization of a high-energy-density beam directly on the surface of an object. It is a permanent mark that cannot be erased. It requires no consumables and has high marking efficiency.
Ultraviolet light has high single photon energy, and with a pulse width of 25ns, the heat-affected zone is very small, which greatly reduces the thermal deformation of the material; its beam quality is high (M2<1.2), and the focused spot diameter is very small, which can reach about 10um. , can mark text, graphics, images, barcodes, QR codes, product serial numbers, autographs… on some tiny electronic components. The boundaries are clear, and it is easy to realize the identification and traceability of one object and one code; at the same time, laser printing The high flexibility of marking can also easily mark some special-shaped components, truly maximizing the value of marking.
