PCB circuit board is good or bad to identify the method

We are not unfamiliar with the application of PCB circuit board, almost in all electronic products will see, the development of science and technology to promote the PCB circuit board industry is growing, people for the layer number of components, precision, reliability requirements are more and more high. There are so many kinds of PCB circuit boards on the market that it is difficult to distinguish between good and bad quality. In this regard, the following will teach you a few ways to distinguish PCB circuit boards.

First, judge from the appearance

1. Appearance of weld

Because there are many PCB circuit board parts, if the welding is not good, the circuit board parts are easy to fall off, which seriously affects the welding quality and appearance of the circuit board, so it is very important to weld firmly.

2. Standard rules for size and thickness

Since PCB circuit boards have different sizes of the thickness of standard circuit boards, users can measure and check according to their own needs.

3. Light and color

Usually external PCB circuit boards are covered with ink to play the role of insulation, if the color of the board is not bright, less ink, that the insulation board itself is not good.

Two, from the plate to judge


1. Ordinary HB card board is cheap and easy to deformation and fracture. It can only be made into a single panel.

2, single-side 94V0, CIM-1 board, the price is relatively higher than cardboard, component surface color is light yellow, mainly used for fire rating requirements of industrial board and power board.

3. Glass fiber board has high cost, good strength, green double-sided, basically most PCB circuit boards are made of this material, copper can be very precise and fine, but the unit board is relatively heavy. PCB circuit board no matter what color printing ink should be smooth and flat, there can be no false copper dew and foaming phenomenon.
