General buyers for pcb circuit board circuit board PCB color is always in doubt , today we have to explain how the PCB circuit board color effect on the performance of the circuit board it?
PCB circuit board is to provide interconnection between electronic components . In fact, there is no direct relationship between color and performance. Different colors can also have an impact on the electrical properties of the executioner . Performance PCB board level is used by the materials used , the layout and board layers and other factors to decide. However , in the process of doing the circuit board , the black color is the most likely to cause , if raw materials and production processes used pcb slight deviation , will be due to chromatic aberration caused by PCB circuit board failure rate increases. This causes increase in production cost.
PCB circuit board materials in our lives is very common , it is made of glass fiber and resin and other components. Combining two kinds of hardening to form a heat insulation , a plate does not bend easily . This is the circuit board substrates. In general, such as glass fiber and resin alone combined into a PCB board can not pass the signal, so we will cover a layer of copper on the surface , and so we called for the PCB copper clad circuit board substrate .
As the black PCB circuit board traces illegible will increase R & D and after-sales maintenance and commissioning phase of the difficulty , if not profound skill of general RD ( R & D ) design and maintenance team of powerful brands, is not easily use black PCB 's . It can be said is a brand with a black PCB design and post repair the RD team is confident that the performance from the side , that is a producer for their confidence in the strength of a reflection .
Each vendor in the choice of when PCB circuit board design will be carefully considered color problems , most with red or blue PCB circuit board PCB board , only to see the situation in black PCB board high-end products .
