Description
Technical Field
The application relates to the field of ceramic element lamination, in particular to a packaging process and a packaging assembly for ceramic element bar block lamination.
Background
When Ceramic element blocks such as MLCC (Multi-layer Ceramic Chip Capacitors) and the like are laminated, if higher pressure and temperature are used, the lamination precision is difficult to control, the produced product has small margin, low cutting yield, discrete product capacity and low capacity hit rate, and the common practice in the MLCC industry is to firstly laminate a dielectric film and a protective film into a block under the condition of lower pressure and temperature, and then laminate the laminated block into a compact solid with the diaphragm in media with good pressure and temperature conductivity such as water, oil and the like under the condition of high temperature and high pressure. The size of the bar after lamination is generally of three specifications: 150mm, 225mm, 310 mm. The first two sizes can be laminated directly without re-splitting, and the last size of the bar block needs to be split into 4 parts (size: 155 mm. about.155 mm) before lamination due to its too large size. In order to prevent the internal electrodes from being broken, deformed and displaced due to uneven stress during lamination. The bar is then laminated with a rigid, flat-surfaced carrier. There are two main ways of packaging in industry:
the method comprises the following steps: the middle of the carrier is provided with a carrier, the two sides of the carrier are respectively provided with a bar block, meanwhile, the carrier and the bar blocks need to be isolated by a PET film and then are sealed in a vacuum mode by a packaging bag, and therefore the phenomenon that laminating media enter the bar blocks to pollute the bar blocks during lamination is avoided.
The second method comprises the following steps: the two sides of the bar block are provided with carriers, meanwhile, the carriers and the bar block need to be isolated by PET films and then are sealed in a vacuum mode by packaging bags, and therefore the phenomenon that laminating media enter the bar block to pollute the bar block during lamination is avoided. (the number of the blocks packed in each bag can be 1, 2, 4, etc. according to the actual situation)
The first method has the disadvantages of high packaging speed and low cost, but has the disadvantages of uneven product surface, easy formation of bread shape and low appearance yield. In the second method, although the surface of the product is relatively flat, the surface of the product is obviously improved, the appearance yield is high, meanwhile, the laminating pressure is more uniform, the capacity is relatively concentrated, the hit rate of the product is high, but the defects are that the process is relatively complex and the cost is high. With the development of society, the requirement for quality in the industry is increased, and the method of laminating two layers is more and more adopted. And under the condition that the capacity is high and the number of lamination layers is large, because the AB of the internal electrode is staggered, the printed electrodes at the two end areas are only 1/2 in the middle area, the stress is small when the internal paste at the two ends is less and laminated, the laminating tightness is insufficient, the product is easy to crack, particularly, triangular cracks are easy to occur at the staggered position of the AB electrode, and the phenomenon is more obvious when the capacity is higher and the number of lamination layers is more. Thus, there is room for further optimization of the lamination technique.
