Details
It is specially used for mechanical drilling of printed boards and placed under the copper clad laminates to be processed or semi-finished printed boards, high density fiberboard for gasket materials to meet processing technology requirements.Product raw materials choose wood raw materials with little deviation in moisture content and density, defibrating technology process stably controls the form of separated fibers of wood chips to meet quality requirements.The hot pressing and paving technology proocess finely controls the stability of the horizontal and vertical density of the fibers, In addition, under the steam injection system, the structure and performance of the product are more stable after hot pressing, which ensures excellent tolerance control even if the finished product is not sanded. Product density is higher than 840g/cm3, high surface hardness, flat surface, no bubbles, no wrinkles, no cracks, no scratches, no ripples, no bump points and impurities, no color inequality .The end face of the product is neat, and the thickness is only 2.0mm and 2.4mm, but the warpage of the product is guaranteed to be small, and the thickness tolerance is small, which is conducive to the fine processing of the printing plate. There are two surface treatment methods: sanding and catt .The size of the product is 1245mm×940mm、1245mm×1042mm、1245mm×1092mm, and the thickness is 2.0mm and 2.4mm.The Products are unprocessed plain wood-base panel. It can be cut, processed and packaged according to customer requirements. The formaldehyde emission of the product is determined by negotiation between the two parties.
