In 2018, 5G is undoubtedly a popular word. Recently, at the 2018 mobile communication conference, HUAWEI released the first 5G commercial chip, and ZTE launched many 5G series base station products, and the 3 operators added at least 12 cities to carry out the 5G pilot... Every news tells us that the business of 5G is getting closer and closer.
5G commercial wave off switch
5G mobile network will go beyond the current mobile network in many ways, including speed, delay, bandwidth and energy consumption. The speed of the 5G mobile network will reach 10000 trillion bits per second, 100 times the current maximum speed; delay can refer to the time required to wait until the response of the other is received. In the current 4G network, the delay is between a few milliseconds to 100 milliseconds, and the delay in the 5G network will be reduced to 1 milliseconds.
But if you want to enjoy the convenience brought by 5G communication, you also need a terminal supporting it. At present, the mobile phone 100% of ordinary users in China does not support it. The coming of the 5G era will set off a new round of replacement boom. As the foundation of the electronics industry, the PCB industry will also usher in new opportunities for development.
PCB laser marking traceability
The arrival of the 5G era has also raised higher requirements for the research and development, production and management of PCB enterprises. Enterprises must provide more cost-effective products to the market at a faster rate, and improve the efficiency of product management as a key link.
A complete data traceability system is needed to build a product from warehousing, production, inspection and storage, so as to achieve internal product quality control. In order to achieve product traceability, we must mark the product with text or bar code to give the product a unique identity card.
There are two ways of traceability mark processing on PCB board, screen printing and laser marking. Silk printing has the following problems: easy to fall off, easy to remove, label rough, pollute the environment and so on. In addition, the portable electronic products are becoming more and more miniaturized, highly integrated and portable, and the welding disks and spacing are becoming smaller and smaller, making the printing counterposition more difficult.
The laser marking, with its precision and flexibility, can overcome the defects of the traditional processing mode which is easy to fall off and the processing precision is not high. It will play an important role in the PCB board industry.
FPC laser cutting
In the electronics industry, flexible circuit boards can be said to be the transfusion pipeline of electronic products. Especially in the light, miniaturization, wearable and folding of the electronic equipment, the flexible circuit board has the advantages of high density, light, flexiability and three-dimensional assembly, which is suitable for the development of the market, and the demand is increasing.
The traditional processing methods of FPC include knife die, V-CUT, milling cutter, stamping and so on. But this kind of mechanical contact plate process has stress, easy to produce edge, dust and not high precision, so it is gradually replaced by laser cutting technology.
As a non-contact tool, laser can be applied to a very small focus (100~500 m) with high intensity light energy (650mW/mm2), so high energy can be used for laser cutting, drilling, marking, welding, drawing and other processing.
Advantages of laser cutting flexible circuit board
As the line density and pitch of FPC products are increasing, and the contour of FPC graphics is becoming more and more complex, the difficulty of making FPC die is becoming more and more difficult. The laser cutting flexible circuit board adopts NC machining form, without die processing, saving the cost of mold opening.
The laser cutting flexible circuit board adopts high performance UV light source, and the beam quality is good and the cutting effect is better.
Because the traditional processing technology is a contact machining method, it is bound to produce the stress of the FPC, which may cause physical damage. The laser cutting flexible circuit board is non-contact processing, effectively avoiding the damage and deformation of the material.
The FPC flexible circuit board cutting machine has been developed by the Jiaming laser to automatically cut the flexible circuit board. Compared with the traditional mechanical blanking, the laser processing does not need any consumables, and the edge processing is more perfect, the speed is up to 3cm/s, it is equivalent to the blink of the eye, and the equipment has finished the length of the small hand finger of the adult.
