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.
Thick copper PCB high temperature resistance, corrosion resistance, mainly used in products with power storage, especially the need to run high voltage and current of electronic products is also need thick copper plate.Thick copper plate requires multi-layer wire printing and multi-layer resistance welding and multilayer copper sinking, thick copper plate because of PCB use and signal current thickness is different, completed copper 20z thick plate is called thick copper plate, 2oz finished copper thickness, hand printed wire printing is not enough to fill the gully between the lines, must be printed two times of welding resistance.When the PCB is made with 2oz and thicker, it will be noted when the welding resistance: thick copper plate, need secondary silk printing.In order to achieve the line is not red, the line surface resistance welding thickness is more than 10um effect.There will be one copper and one secondary copper. The main purpose of one copper is to provide sufficient copper thickness for the secondary copper etching to ensure that the copper thickness after the secondary copper etching can meet the standard requirements of the customer.
Thick copper PCB plate is a special plate, and Best Technology Co., Ltd. is committed to providing customers with the most suitable and innovative products and the most satisfactory service.
