What is the PCB thick copper plate?The thick copper plate is displayed in the waiting process, with certain technical threshold and operation difficulty, and the cost is also relatively expensive. A layer of copper foil is bonded in the outer layer of FR-4. When the copper thickness is 2oz is completed, it is defined as the thick copper PCB plate.PCB thick copper plate has a very good extension performance, not limited by the processing temperature, high baking point can be used when oxygen blowing, low temperature unchanged brittle and other hot baking welding methods, and also fire prevention, spread in non-combustible materials, thick copper PCB its thickness is different, the specific application occasions are also very different.

PCB proofing, thick copper plate has good compressive strength and production and processing adaptability, in addition, it also apply to modules section metope, buckle lock system, vertical edge bite, bem system, rain water drainage pipe system and so on all kinds of processing technology and the system, but also be governed by the provisions of this system requires the various production and processing.

The thick copper plate is classified as a special plate. BEST TECHNOLOGY CO., LIMITED thick copper plate is UL certified to 2 layers of 15oz and the multi-layer plate is UL certified to 13oz for ultra thick copper.
